OneStream Review
OneStream is a unified CPM platform: group consolidation, financial close, reporting, planning and forecasting running on one data model rather than a stack of connected point tools. It is bought mostly by large multi-entity organizations replacing Oracle Hyperion HFM, SAP BPC or TM1, and its Account Reconciliations, Transaction Matching, Journal Entry Manager and Task Manager solutions are where it overlaps BlackLine. It is not a close checklist you switch on. Licensing is quote only, implementation is partner led and measured in quarters, and since April 1, 2026 the company has been owned by the private equity firm Hg, which also owns Prophix, LucaNet and a stake in insightsoftware.
OneStream is the enterprise answer to a question BlackLine does not answer: statutory consolidation. If you are running Hyperion HFM past its usefulness, consolidating dozens of legal entities, and tired of your consolidation engine, your close tooling and your planning model being three different systems with three different hierarchies, OneStream is the credible unifier and a four time Gartner Magic Quadrant Leader for Financial Close and Consolidation, placed furthest in Vision in 2026.
Its agent surface is genuinely the most open of any enterprise close vendor we have reviewed: the Finance Agentic Layer went generally available on May 19, 2026 built on open Model Context Protocol, with Claude named explicitly, permissions enforced against the user's own OneStream identity, and full audit logging. The catches are large and real.
Implementation is the heaviest in this category, commonly 6 to 18 months and 500,000 to 2,000,000 dollars or more in partner services against a license that third parties put at roughly 150,000 to 300,000 dollars a year, and data migration out of HFM alone routinely eats 30 to 50 percent of that budget. Pricing is quote only with no published list, no calculator and reported renewal increases of 25 percent or more. And the ownership change matters: the February 26, 2026 results are the last audited public financials that will ever exist, so every customer, retention and growth number from here is vendor stated. Buy it for consolidation depth plus close in one model, negotiate the solution entitlement list and the escalator cap in writing now while Hg still needs a clean retention story, and do not buy it as a cheaper BlackLine.
- ✓Multi-state or multi-jurisdiction payroll where compliance is the real exposure
- ✓Mid-market to enterprise (50 to 1,000+) needing benefits, HR, and audit-ready reporting
- ✓CFOs who want one accountable vendor to absorb tax and penalty risk
- !Cost-sensitive teams under ~25 employees with simple single-state payroll, where Gusto is cheaper
- !Buyers who need all-in pricing transparency upfront
- !Software-first teams wanting native real-time API and GL sync as a core workflow
The jobs a controller actually hires OneStream for
Group consolidation and statutory reporting
The core job and the one BlackLine does not do. Global consolidation with intercompany eliminations, currency translation, ownership and acquisition management, and group reporting under US GAAP and IFRS, all in a single engine rather than an ERP consolidation plus a separate reporting layer.
Replacing Oracle Hyperion HFM, SAP BPC or TM1
The dominant sales motion, and OneStream's founding thesis: the co-founders invented Hyperion Financial Management and Hyperion FDM before building the platform that displaces them. Oracle Premier Support for HFM 11.2 ends December 2030, and Audit Friendly first-party data sizes the remaining migration wave: as of August 7, 2026, Oracle Hyperion is still named in 805 live finance postings on our job board, well ahead of OneStream's 528, so the installed base OneStream sells against is larger than the one it has already taken.
Account reconciliations tied to the reported numbers
Reconciliations run on the same application, security model, hierarchies and workflow as the consolidation, so trial balance data is single sourced and users can drill from a reported balance directly into the reconciliation that supports it. AI assisted reconciliation, continuous anomaly monitoring and risk based exception reporting sit on top. This is the module that competes head on with BlackLine.
High volume transaction matching
Transaction Matching launched October 14, 2025 as part of Modern Financial Close, automating high volume reconciliations across intercompany, invoice to receipt and corporate credit card data, with OneStream claiming up to 95 percent of routine matches automated so teams work exceptions instead of ticking and tying (published claim).
Controlled journal entry across multiple ERPs
Journal Entry Manager, also launched October 14, 2025, centralizes journal entry creation, approval and lifecycle control across multiple ERPs and business units with pre-validation and audit trails, aimed at groups whose entities sit on different ledgers.
Planning, forecasting and specialist accounting on the same model
Because it is one platform, budgeting, forecasting and scenario planning read the same actuals the consolidation produces, and specialist solutions extend the same model: Tax Provision for ASC 740 disclosures, Lease Accounting for ASC 842 and IFRS 16, and ESG Planning and Reporting launched in October 2025.

What it actually takes to go live
Reported timelines run 6 to 9 months for a consolidation only scope, 9 to 15 months for multi-module deployments, and 12 to 18 months for a full Oracle Hyperion HFM migration. Partner services are reported at 500,000 to 2,000,000 dollars or more, and year one total cost of ownership commonly runs 2 to 4 times the annual license. The critical path is almost always data: migrating history, hierarchies and mappings out of the legacy system is reported at 30 to 50 percent of the implementation budget. Practitioner sources are consistent that deployments almost always require a certified implementation partner, and that OneStream's breadth is itself a risk, since the temptation to build consolidation, close, reconciliation and planning at once is how programs slip. There is a real deadline behind many of these projects: Oracle Premier Support for HFM 11.2 ends in December 2030, so a 12 to 18 month migration started in 2026 lands comfortably inside it.
A generally available, first-party MCP layer that names Claude by name, governed by your own OneStream permissions, but version gated and admin configured rather than turnkey.
Existence is settled: OneStream announced general availability of the SensibleAI Finance Agentic Layer on May 19, 2026, built on open Model Context Protocol, explicitly to let Copilot, ChatGPT, Claude and Gemini reach OneStream data. Four SensibleAI agents are generally available.
Finance Analyst answers natural language questions against the financial cubes and executes roll-ups, compliance calculations and custom logic inside OneStream's model, returning reports, calculations, trend analysis, visual outputs and variance analysis.
Search Agent runs retrieval over policies, documents and platform knowledge with transparent sourcing. Deep Analysis combines structured financial data with unstructured documents across large document sets. Forecast Agent analyzes forecast accuracy, drivers and scenarios, and is available only to SensibleAI Forecast customers.
On scope, the layer is predominantly analytical: OneStream's materials describe translating natural language into structured queries, deterministic computation through its own engines, and stateful execution of multi-step tasks including initiating workflows, but they do not document a general path for an external agent to post or overwrite financial data.
Every interaction is authenticated against the user's own OneStream identity and enforced against existing role based permissions, with period locks, approvals, audit logging and administrator visibility into usage.
On turnkey versus configured, it is clearly configured: the Agentic Finance Toolkit (MCP finance tools, semantic layer, monitoring services) is available starting Platform Version 9.3 and Developer Studio from 9.2.0, and an Agentic Gateway acts as the mandatory entry point for every agentic request, handling routing, identity and access resolution, rate limiting and budget controls.
No MCP endpoint URL, connection instructions or public sandbox appear in OneStream's public materials, so pre-purchase evaluation of the agent surface is not possible. For context, this is meaningfully more open than BlackLine, which has no first-party MCP server at all.
The demos that matter, none of the noise
OneStream, kept current
OneStream FAQ
How much does OneStream really cost?
There is no published price, no calculator and no public tiers, so everything here is reported or estimated by third parties. Entry deals are reported at about 50,000 to 100,000 dollars per year, typical enterprise deployments at about 150,000 to 300,000 dollars or more per year with an average annual license around 178,000 dollars, and large enterprise at 300,000 to 400,000 dollars or more. Implementation is separate and reported at 250,000 to 2,000,000 dollars or more, commonly 1.5 to 2 times annual license for moderate complexity and 3 to 5 times for complex global programs, so year one typically lands at 2 to 4 times the license. Annual escalators are reported at 5 to 10 percent and negotiable, with customer reports of renewal proposals of 25 percent or more.
Does the Hg take-private change anything for buyers?
Two things concretely, and one thing only in prediction. Concretely: OneStream's Class A stock stopped trading on Nasdaq on April 1, 2026, and the February 26, 2026 full year results are the last audited public financials, so from here you cannot check a customer count, retention rate or growth figure against a filing. Also concretely, Hg now owns Prophix and LucaNet and holds a stake in insightsoftware, so one firm controls several CPM vendors at once. In prediction only: Forrester tells buyers to expect movement toward bundled or consumption based pricing within 18 to 24 months and to get support and pricing assurances in the contract now. BARC reads it the other way, noting Hg has not historically been aggressive with acquired vendors' customers and that removing quarterly public market pressure could help the roadmap. No post-close pricing action has actually been announced as of August 2026.
Is OneStream a replacement for BlackLine?
Sometimes, but they are aimed at different jobs and the overlap is narrower than it looks. OneStream is a unified CPM platform whose center of gravity is group consolidation, close and planning on one model; BlackLine is a close and controls layer that sits on top of your ERPs and does not consolidate. They meet in Account Reconciliations, Transaction Matching, Journal Entry Manager and Task Manager, and OneStream publishes customer stories of replacing BlackLine, including one that reported reconciliations 75 percent faster and about 100,000 dollars a year saved in software licenses. The counterweight is maturity and scale: BlackLine has roughly 4,260 customers and about 390,000 users on a close only footprint, while OneStream's Journal Entry Manager and Transaction Matching only launched in October 2025. If your problem is reconciliation and controls depth alone, BlackLine is still the benchmark. If your problem is that consolidation, close and reconciliation live in three systems, OneStream is the reason to look.
Can an AI agent like Claude connect to OneStream?
Yes, and this is genuinely one of the more open agent surfaces in enterprise finance software. OneStream's Finance Agentic Layer went generally available on May 19, 2026, built on open Model Context Protocol, and names Claude alongside ChatGPT, Copilot and Gemini. Every request is authenticated against the user's own OneStream identity and enforced against their existing role based permissions, with period locks, approvals and audit logging. Two caveats. It is scoped mainly to querying, computation and workflow initiation; OneStream does not document general external write access to financial data. And it is not turnkey: the Agentic Finance Toolkit needs Platform Version 9.3, Developer Studio needs 9.2.0, an administrator must stand up the mandatory Agentic Gateway, and no endpoint or public sandbox is published, so you cannot evaluate the agent surface before you buy.

OneStream Review
OneStream is a unified CPM platform: group consolidation, financial close, reporting, planning and forecasting running on one data model rather than a stack of connected point tools. It is bought mostly by large multi-entity organizations replacing Oracle Hyperion HFM, SAP BPC or TM1, and its Account Reconciliations, Transaction Matching, Journal Entry Manager and Task Manager solutions are where it overlaps BlackLine.

Independently scored across six dimensions. Every dimension is sourced, and we say whether a claim is published, reported, or estimated.
Very strong, and broader than a close-only tool. Global consolidation with intercompany eliminations, currency translation and acquisition management sits in the same engine as Account Reconciliations, Transaction Matching, Journal Entry Manager and Task Manager, so reported balances drill straight to the reconciliation that supports them. US GAAP, IFRS and SOX 302 and 404 are named on the product, alongside Tax Provision for ASC 740, Lease Accounting for ASC 842 and IFRS 16, and ESG reporting. Gartner named OneStream a Leader for the fourth consecutive year in the 2026 Magic Quadrant for Financial Close and Consolidation Solutions and placed it furthest in Completeness of Vision among the 14 vendors evaluated. The honest caveat is age: Journal Entry Manager and Transaction Matching only launched on October 14, 2025, so their installed base and audit track record are far younger than BlackLine's.
Built for large, complex groups. OneStream states 1,900 plus customers and 21 percent of the Fortune 500 (vendor stated; the same boilerplate said 1,800 plus and 18 percent as recently as April 2026, and neither figure is now checkable against a filing). Audit Friendly first-party data backs the adoption story and shows where it lands: as of August 7, 2026, 528 live postings on our finance job board name OneStream, more than any other close or CPM vendor we track, ahead of BlackLine at 342, Workiva at 235, FloQast at 132 and Trintech at 10, and the hiring is concentrated in exactly the profile you would expect, with Regal Rexnord, ASSA ABLOY, Xylem, Koch, Wabtec, nVent, Danaher, Fortive, Brookfield Renewable and Barrick Gold all recruiting against it. A new cube engine announced at Splash 2026 claims 2 to 4 times improvement across calculation, consolidation, translation and load, one consolidation cited moving from 1 hour 36 minutes to 28 minutes, and data unit sizing guidance raised 10 times from 2 million to 20 million rows. The practical ceilings that practitioners report are concurrency during the close window, a documented 18 dimension model limit (reported), and Azure only deployment.
The most open agent surface of any enterprise close vendor in our review set, though not turnkey. The Finance Agentic Layer went generally available on May 19, 2026, built on open Model Context Protocol, and OneStream names Claude, ChatGPT, Microsoft Copilot and Gemini as supported clients. Four SensibleAI agents are generally available (Finance Analyst, Search, Deep Analysis, Forecast), every request is authenticated against the user's own OneStream identity and enforced against existing role based permissions, and governance covers period locks, approvals and audit logging. What holds the score back is real: the Agentic Finance Toolkit requires Platform Version 9.3 and Developer Studio requires 9.2.0, an Agentic Gateway must be stood up as the mandatory entry point for every agentic request, no MCP endpoint URL or connection instructions are published, there is no public sandbox, write scope beyond workflow initiation is undocumented, and the Forecast Agent is gated to SensibleAI Forecast customers.
Better than the category average but still partner shaped. OneStream states 98 percent gross retention (vendor stated, never verifiable in a filing we could read), and BARC's review panel scores customer satisfaction 8.4 out of 10 across 44 reviews with strong marks for project success. G2 rates it 4.6 across roughly 160 reviews and Capterra 4.8 across roughly 83, higher than BlackLine's 4.5 but on a fraction of the review volume. In practice, day to day problem solving routes through your implementation partner or an internal OneStream administrator, and the partner tiering (Diamond, Platinum, Gold, Silver) exists precisely because that is where the expertise lives.
The single biggest reason to hesitate, and the weakest dimension here. Reported timelines run 6 to 9 months for consolidation only, 9 to 15 months for multi-module, and 12 to 18 months for a full Hyperion HFM migration, with partner services reported at 500,000 to 2,000,000 dollars or more and year one total cost of ownership at roughly 2 to 4 times annual license. Implementation runs about 1.5 to 2 times annual license for moderate complexity and 3 to 5 times for complex global programs (reported). Data migration alone, moving history, hierarchies and mappings out of HFM, BPC, TM1 or spreadsheets, is reported at 30 to 50 percent of the implementation budget and routinely underestimated. Practitioner sources are blunt that deployments almost always require a certified partner.
No public list price, no calculator, no published tiers, and now no audited financials either. Third party trackers put entry deals at roughly 50,000 to 100,000 dollars per year, typical enterprise at 150,000 to 300,000 dollars or more, average annual license around 178,000 dollars, and large enterprise at 300,000 to 400,000 dollars plus, all reported and estimated. Annual escalation is reported at 5 to 10 percent and negotiable, with customer reports of renewal increases of 25 percent or more. Sources also conflict on which Solution Exchange solutions are included in the platform license and which are separately licensed, which is exactly the ambiguity that costs money at renewal. The take-private compounds it: with no more 10-K, buyers lose the one public benchmark that made OneStream's growth checkable.

OneStream is the enterprise answer to a question BlackLine does not answer: statutory consolidation.

- Multi-entity groups running Oracle Hyperion HFM, SAP BPC or TM1 that need to migrate before support and skills run out, and want consolidation, close and planning on one model instead of three.
- Large organizations where statutory consolidation is the hard requirement: intercompany eliminations, currency translation, acquisition accounting and group reporting under US GAAP and IFRS.
- Finance teams tired of reconciliations living in a separate system from the numbers they support, who value drilling from a reported balance straight into the reconciliation and the matched transactions behind it.
- Buyers who want their own AI assistant to reach governed financial data, since OneStream ships a generally available MCP based layer that Claude and other external agents can connect to under the user's existing OneStream permissions.
- Mid-market close teams that just need coordination and visibility: OneStream is enterprise CPM with an enterprise price, and FloQast or a well run checklist gets most of the value for a fraction of the cost and time.
- Companies below roughly 500 million dollars in revenue without genuinely complex consolidation: third party guidance is explicit that the cost is prohibitive at that size, and OneStream is not a cost savings play.
- Buyers who need reconciliation and transaction matching depth proven at scale today: BlackLine has about 4,260 customers on a close and controls only footprint, while OneStream's Journal Entry Manager and Transaction Matching only shipped in October 2025.
- Anyone who needs transparent or predictable pricing, or who wants to verify vendor claims against audited numbers: pricing is quote only and the February 26, 2026 results are the last public financials that will ever exist.
The jobs a controller actually hires OneStream for
Six jobs, each with the two-minute clip that shows it. Hover a card to preview, click to watch.
Group consolidation and statutory reporting
The core job and the one BlackLine does not do. Global consolidation with intercompany eliminations, currency translation, ownership and acquisition management, and group reporting under US GAAP and IFRS, all in a single engine rather than an ERP consolidation plus a separate reporting layer.
Replacing Oracle Hyperion HFM, SAP BPC or TM1
The dominant sales motion, and OneStream's founding thesis: the co-founders invented Hyperion Financial Management and Hyperion FDM before building the platform that displaces them. Oracle Premier Support for HFM 11.2 ends December 2030, and Audit Friendly first-party data sizes the remaining migration wave: as of August 7, 2026, Oracle Hyperion is still named in 805 live finance postings on our job board, well ahead of OneStream's 528, so the installed base OneStream sells against is larger than the one it has already taken.
Account reconciliations tied to the reported numbers
Reconciliations run on the same application, security model, hierarchies and workflow as the consolidation, so trial balance data is single sourced and users can drill from a reported balance directly into the reconciliation that supports it. AI assisted reconciliation, continuous anomaly monitoring and risk based exception reporting sit on top. This is the module that competes head on with BlackLine.
High volume transaction matching
Transaction Matching launched October 14, 2025 as part of Modern Financial Close, automating high volume reconciliations across intercompany, invoice to receipt and corporate credit card data, with OneStream claiming up to 95 percent of routine matches automated so teams work exceptions instead of ticking and tying (published claim).
Controlled journal entry across multiple ERPs
Journal Entry Manager, also launched October 14, 2025, centralizes journal entry creation, approval and lifecycle control across multiple ERPs and business units with pre-validation and audit trails, aimed at groups whose entities sit on different ledgers.
Planning, forecasting and specialist accounting on the same model
Because it is one platform, budgeting, forecasting and scenario planning read the same actuals the consolidation produces, and specialist solutions extend the same model: Tax Provision for ASC 740 disclosures, Lease Accounting for ASC 842 and IFRS 16, and ESG Planning and Reporting launched in October 2025.

Compare on what matters
What it actually costs
Here's what it really costs: published rates where a vendor lists them, aggregated quote data where they don't, plus a path to your own number.
A narrow first footprint, most often consolidation and close for a limited entity and user count, on the same unified platform. There is no published entry SKU; this is the low end of observed contracts.
The common shape: consolidation and close plus one or more of planning, reporting and analytics, account reconciliation or tax provision, across multiple entities and currencies, with per user rates reported at roughly 20 to 30 dollars per month at scale.
Wide deployments across consolidation, close, reconciliation, matching, journals, planning, tax and ESG for large multi-national groups, typically on a three to five year commitment.
Partner delivered design and build: chart of accounts and entity hierarchy design, cube and dimension modeling, ERP and source data integration, migration off HFM, BPC or TM1, close and reconciliation configuration, training and change management.
What it actually takes to go live
Vetted Workiva partnersFind a partner →
SEC reporting manager or controller as owner, technical accounting for disclosures and tagging decisions, the SOX or internal audit lead for controls solutions, the sustainability controller for ESG scope, light IT involvement for SSO and data connectors, Workiva customer success plus its Professional Services team, and often an advisory partner (the Big 4 and firms like Riveron implement on Workiva; Deloitte has built CSRD compliance solutions on the platform).
History, hierarchies, mappings and the accumulated logic of a decade of consolidations do not lift cleanly. This is the most underestimated line in OneStream programs (reported). Decide early how many years of history you truly need, get the source extraction scoped by someone who has done it before, and plan a parallel close before you cut over.
Because consolidation, close, reconciliation, planning, tax and ESG all live on one model, it is tempting to build them together. Multi-module deployments are reported at 9 to 15 months versus 6 to 9 for consolidation only. Sequence it: land the consolidation and close, prove the model, then add reconciliation, matching and planning.
OneStream deployments almost always require a certified partner, and partner tier is a proxy for how many implementations the team has actually finished. Get competitive bids, insist on named consultants rather than a bench, check references at your entity count and legacy system, and confirm who owns the build and the knowledge transfer after go live.
OneStream markets 70 plus Solution Exchange solutions as extensions rather than bolt-on products, but public sources disagree on which are covered by the platform license and which are separately licensed. Name every solution you expect to use over the next 24 months, including Account Reconciliations, Transaction Matching, Journal Entry Manager, Task Manager, Tax Provision and Lease Accounting, and get the entitlement and any future pricing committed in the contract.
Hg completed its take-private on April 1, 2026. Forrester advises buyers to expect movement toward bundled or consumption based pricing within 18 to 24 months and to demand contractual assurances on support levels rather than waiting for renewal. BARC's read is more benign, noting Hg has not historically been aggressive with acquired vendors' customers. Nothing has actually changed in pricing as of August 2026, but a renewal cap and a support SLA in writing cost nothing to ask for while a new owner needs a clean retention story.
Entity hierarchy, account structure and dimensionality are foundational and painful to rework after go live. Practitioner reports cite an 18 dimension model limit that constrains the most complex scenario modeling (reported), and OneStream's own guidance sizes data units in the millions of rows. Design against your future entity structure and reporting needs, and pressure test the model with your largest consolidation before you accept the build.
Governed AI is strong inside the platform; the external agent surface is real REST APIs plus an MCP gateway that is announced but not yet self serve.
Existence is settled: OneStream announced general availability of the SensibleAI Finance Agentic Layer on May 19, 2026, built on open Model Context Protocol, explicitly to let Copilot, ChatGPT, Claude and Gemini reach OneStream data. Four SensibleAI agents are generally available.

On turnkey versus configured, it is clearly configured: the Agentic Finance Toolkit (MCP finance tools, semantic layer, monitoring services) is available starting Platform Version 9.3 and Developer Studio from 9.2.0, and an Agentic Gateway acts as the mandatory entry point for every agentic request, handling routing, identity and access resolution, rate limiting and budget controls.
No MCP endpoint URL, connection instructions or public sandbox appear in OneStream's public materials, so pre-purchase evaluation of the agent surface is not possible. For context, this is meaningfully more open than BlackLine, which has no first-party MCP server at all.
OneStream, kept current
At Splash 2026 OneStream announced a next generation cube engine claiming 2 to 4 times improvement across calculation, consolidation, translation and load with no migration project required, one consolidation cited dropping from 1 hour 36 minutes to 28 minutes, and data unit sizing guidance raised from 2 million to 20 million rows. It also launched Developer Studio (Platform Version 9.2.0 and later), which exposes business rules as native .NET projects for use in VS Code, Cursor or Rider with AI coding assistants, and the Agentic Finance Toolkit (Platform Version 9.3 and later) comprising MCP finance tools, a semantic layer and monitoring services, fronted by a mandatory Agentic Gateway with identity resolution, rate limiting and budget controls.
OneStream made its Finance Agentic Layer generally available, built on open Model Context Protocol so external AI tools including Claude, ChatGPT, Microsoft Copilot and Gemini can reach OneStream data under the user's own identity and role based permissions with full audit trails. Four SensibleAI agents reached general availability: Finance Analyst, Search, Deep Analysis and Forecast. Constellation Research characterized this class of interoperability move as table stakes, arguing all agents will eventually have to share common protocols.
Hg completed its acquisition of OneStream at 24.00 dollars per share in cash, about 6.4 billion dollars in equity value, and OneStream's Class A common stock ceased trading on Nasdaq. Hg is majority voting shareholder with General Atlantic and Tidemark as minority investors. Tom Shea remains CEO and the leadership team stayed in place. The deal was announced January 6, 2026 at a 31 percent premium to the January 5 closing price and a 27 percent premium to the 30 day volume weighted average, and closed 17 months after the 2024 IPO. KKR, which held majority voting power after taking OneStream public, approved the transaction.
Gartner named OneStream a Leader in the 2026 Magic Quadrant for Financial Close and Consolidation Solutions for the fourth consecutive year and placed it furthest for Completeness of Vision among the 14 vendors evaluated. Gartner's own report is behind a paywall, so the placement is quoted from OneStream's newsroom, a self-interested source for interpretation but a reliable one for the fact that the placement exists.
OneStream reported full year 2025 results: total revenue 601.9 million dollars, up 23 percent, subscription revenue 550.0 million dollars, up 28 percent, fourth quarter total revenue 163.7 million dollars, up 24 percent, GAAP operating margin negative 16 percent versus negative 65 percent in 2024, non-GAAP operating margin 5 percent versus 0 percent, and free cash flow 95.6 million dollars versus 58.5 million dollars. Citing the pending Hg acquisition, the company held no earnings call and issued no forward guidance. With the deal closed on April 1, 2026, these are the final audited public numbers, and every customer, retention and growth figure published from here is vendor stated.
At Splash EMEA 2025 in London, OneStream launched Modern Financial Close, adding Journal Entry Manager for centralized journal creation, approval and lifecycle control across multiple ERPs and business units, and Transaction Matching for high volume intercompany, invoice to receipt and corporate credit card reconciliation, with a published claim of up to 95 percent of routine matches automated. The same release introduced AI powered ESG Planning and Reporting and expanded SensibleAI Studio, which had roughly doubled its routine count since general availability in June 2025.

Entry deals are reported at about 50,000 to 100,000 dollars per year, typical enterprise deployments at about 150,000 to 300,000 dollars or more per year with an average annual license around 178,000 dollars, and large enterprise at 300,000 to 400,000 dollars or more. Implementation is separate and reported at 250,000 to 2,000,000 dollars or more, commonly 1.5 to 2 times annual license for moderate complexity and 3 to 5 times for complex global programs, so year one typically lands at 2 to 4 times the license. Annual escalators are reported at 5 to 10 percent and negotiable, with customer reports of renewal proposals of 25 percent or more.
Two things concretely, and one thing only in prediction. Concretely: OneStream's Class A stock stopped trading on Nasdaq on April 1, 2026, and the February 26, 2026 full year results are the last audited public financials, so from here you cannot check a customer count, retention rate or growth figure against a filing. Also concretely, Hg now owns Prophix and LucaNet and holds a stake in insightsoftware, so one firm controls several CPM vendors at once. In prediction only: Forrester tells buyers to expect movement toward bundled or consumption based pricing within 18 to 24 months and to get support and pricing assurances in the contract now. BARC reads it the other way, noting Hg has not historically been aggressive with acquired vendors' customers and that removing quarterly public market pressure could help the roadmap. No post-close pricing action has actually been announced as of August 2026.
Sometimes, but they are aimed at different jobs and the overlap is narrower than it looks. OneStream is a unified CPM platform whose center of gravity is group consolidation, close and planning on one model; BlackLine is a close and controls layer that sits on top of your ERPs and does not consolidate. They meet in Account Reconciliations, Transaction Matching, Journal Entry Manager and Task Manager, and OneStream publishes customer stories of replacing BlackLine, including one that reported reconciliations 75 percent faster and about 100,000 dollars a year saved in software licenses. The counterweight is maturity and scale: BlackLine has roughly 4,260 customers and about 390,000 users on a close only footprint, while OneStream's Journal Entry Manager and Transaction Matching only launched in October 2025. If your problem is reconciliation and controls depth alone, BlackLine is still the benchmark. If your problem is that consolidation, close and reconciliation live in three systems, OneStream is the reason to look.
Yes, and this is genuinely one of the more open agent surfaces in enterprise finance software. OneStream's Finance Agentic Layer went generally available on May 19, 2026, built on open Model Context Protocol, and names Claude alongside ChatGPT, Copilot and Gemini. Every request is authenticated against the user's own OneStream identity and enforced against their existing role based permissions, with period locks, approvals and audit logging. Two caveats. It is scoped mainly to querying, computation and workflow initiation; OneStream does not document general external write access to financial data. And it is not turnkey: the Agentic Finance Toolkit needs Platform Version 9.3, Developer Studio needs 9.2.0, an administrator must stand up the mandatory Agentic Gateway, and no endpoint or public sandbox is published, so you cannot evaluate the agent surface before you buy.
