Esker Review
Esker is a Lyon-based cloud suite for the Office of the CFO whose accounts payable, procurement and supplier management modules automate invoice capture, matching, approvals and e-invoicing compliance for mid-size and large companies on SAP, Oracle, Microsoft or Sage ERPs.
Independently scored, one dimension at a time. Every dimension is sourced, and we say whether a claim is published, reported, or estimated.
Esker's about page reports 3,000+ customers, 1.12M+ users and about 250 million euros of 2025 revenue (checked 27 September 2026). The AP page lists 135+ currencies, and Lufthansa Group Business Services chose Esker AP for five ERPs and three service centers (release of 4 September 2025). The US terms cap the platform at 2 million master data records and a set number of ERP instances and company codes, with pricing reviewed if exceeded.
Esker's security datasheet reports SOC 1 Type 2 (SSAE 18 and ISAE 3402) since 2014 and ISO 27001 audited by A-lign, and its AP page describes matching against purchase orders and goods receipts, rule-based approval routing and archived workflow history (checked 27 September 2026). E-invoicing compliance covers 60+ countries, and Esker announced on 5 January 2026 that France's DGFiP had given it final registration as a certified platform. Points come off because no SOC 2 report is named on Esker's pages, the datasheet dates from 2020, and no 1099 filing feature is described.
Esker lists certified SAP ECC and S/4HANA integration, including S/4HANA Cloud extensions at Clean Core Level A, plus pre-built Oracle EBS, JD Edwards and NetSuite connectors and Dynamics 365 Finance and Operations and Business Central connectors (integration pages, checked 27 September 2026). Sage X3, Sage 100 and FRP 1000 are covered, though Esker's multi-ERP page credits partner Flowwa with the Sage integration and partner B.Workshop with the JD Edwards and NetSuite links, and partners build QAD and Epicor Prophet 21 links. Oracle Fusion connects through REST APIs, and no QuickBooks Online, Xero or Sage Intacct connector is listed.
A dedicated Customer Success team, local Professional Services consultants and the Esker Support Hub are described on esker.com (checked 27 September 2026). The US technical support terms (page dated 2022) set standard hours of 8:30 to 5:00 Central on weekdays, with response goals of 2 hours for critical cases and 24 hours for minor ones. SoftwareReviews shows 97 on likeliness to recommend across 32 reviews (reported), a small sample.
Esker Professional Services delivers projects under a paid statement of work using an Agile method, per its consulting page and the US terms (checked 27 September 2026). Esker says its pre-built connectors post a first Dynamics 365 or Sage invoice in about three days (vendor-claimed), and the Aprolis story reports a two to three month go-live. The terms also require an update project at least every three years under a separate paid SOW.
Esker does not move money itself. The Esker Pay page lists domestic and international payments, card payments, dynamic discounting and supply chain financing through fintech partners such as Corpay, Stripe and LSQ (checked 27 September 2026), and Corpay's release of 10 February 2022 adds virtual cards and cross-border payments. Supplier Management validates bank details before payment, while partner fees and card rebates are not published.
Inside the product, Synergy AI handles capture, coding, matching and anomaly checks, and Esker claims 80+ percent of invoices go touchless (vendor-claimed, AP page, checked 27 September 2026). Outside it, no first-party MCP server appears in the MCP registry, GitHub or Esker's docs, and the 9 September 2026 Synergy Agentic Framework release names MCP and A2A without documentation or dates. The only public API is the SOAP Esker on Demand web service, which works at the level of documents and transports.
Esker publishes no prices, and esker.com/pricing returns a 404 (checked 27 September 2026). Vendr and SpendHound have no public Esker page, and ERP Research lists pricing as quote-based by invoice volume, modules and scope. The US terms do disclose some charges: a 1 percent card convenience fee, a 100 percent early termination charge and an uplift of up to 2 percent after large change orders.
Strong multi-ERP AP and e-invoicing for enterprises, with quote-only pricing, strict terms and no MCP server.

You are buying a cloud workflow layer that sits over one or more ERPs. Esker captures supplier invoices from email, EDI, mail, fax and portals, matches them to purchase orders and receipts, routes approvals and posts to the ERP, then archives the record. Procurement, Supplier Management, Sourcing, Contract Management and Expense Management run on the same platform, and order-to-cash is there if you want it later. Gartner named Esker a Leader in its Magic Quadrant for Accounts Payable Applications in 2025 and again on 18 June 2026, per Esker's release.
The catch is commercial. Esker publishes no prices, and its own financial reports split SaaS revenue into subscription fees and per-transaction fees, which suggests cost tracks document volume. Implementation work by Esker is billed on a separate statement of work. The US terms (last updated 30 August 2024) charge 100 percent of the remaining subscription if you leave before the initial term ends, and require an update project at least every three years under a separate paid SOW. The AI agents live inside Esker; the public API is a SOAP web service, and MCP appears only in a 9 September 2026 announcement.
Before signing, get in writing: the per-document fee by volume tier and the overage rate, a renewal price cap (the terms include none), the cost of each three-yearly update project, archive retention and bulk export at exit, support hours for every region you run AP from, and whether your ERP connector is Esker-built or partner-built. If AI agents are on the roadmap, ask for a dated commitment on REST and MCP access.
- A multinational on two or more ERPs such as SAP, Oracle or Dynamics 365 that wants one AP workflow across entities, currencies and shared service centers.
- Companies facing e-invoicing mandates in France and the wider EU that want supplier invoice processing and compliance on one platform.
- Finance and procurement teams that want AP, purchase requests, supplier onboarding and sourcing from one vendor, with order-to-cash available later.
- Small US businesses on QuickBooks Online, Xero or Sage Intacct: Esker lists no pre-built connector for them.
- Teams that want Claude or another agent to run AP today: there is no MCP server, and the public API is SOAP web services.
- Buyers who need a published price or an easy early exit: pricing is quote only, and leaving early costs the rest of the term.
The jobs a finance team actually hires Esker for
Jobs, mapped to how finance teams actually buy.
Capture and post invoices from every channel
Esker takes invoices by email, EDI, mail, fax and supplier portal into one workflow, extracts header and line data without templates, applies business rules and posts to the ERP. Esker claims 80+ percent of invoices need no manual touch and 50+ percent faster approvals (vendor-claimed, AP page, checked 27 September 2026).
Meet e-invoicing mandates from one platform
Esker supports Peppol and local e-invoicing models and announced on 5 January 2026 that France's DGFiP had given it final registration as a certified platform, ahead of the 1 September 2026 start for large and mid-size French companies. AP and customer invoice delivery share the platform, so one vendor covers inbound and outbound mandates.
Vet suppliers before their first payment
Esker Supplier Management gives suppliers a self-service portal for company data, tax forms, certificates and bank details, then validates tax IDs, screens sanctions lists and verifies bank accounts. EcoVadis sustainability scores have been available inside onboarding since 7 April 2026.
Run AP across several ERPs and service centers
Lufthansa Group Business Services chose Esker AP to standardize invoice processing across five ERPs and centers in Frankfurt, Krakow and Manila, per Esker's release of 4 September 2025. It later added Esker Expense Management.
Guide employee purchases into clean POs
Esker Procurement takes requests through catalogs, quotes or a natural-language intake agent, routes them through budget checks and approvals, and issues POs whose receipts feed invoice matching. Swinburne University of Technology reports 75 percent less processing time and 3x faster approvals (vendor-claimed, Esker procurement page, checked 27 September 2026).

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.
Priced by module (AP, Procurement, Supplier Management, Sourcing, Contracts, Expense). Esker reports SaaS revenue as subscription plus per-transaction fees.
Implementation and customization are billed on a separate statement of work, plus pre-approved travel, per the US terms.
Sold as a separate service; without it, processed documents are kept 60 days and then erased, per the US terms.
Updates must be installed at least every three years under a separate SOW for an additional fee; skipping one ends technical support.
Applies to the subscription once change orders for one business process reach 40 hours or more, per the US terms.
Charged when a customer pays Esker's own invoices by credit card, per the US terms.
Feature releases, upgrades and bug fixes to the hosted platform install automatically at no cost, per the US terms.
What it actually takes to go live
Section 11.1 of Esker's US Terms of Service (last updated 30 August 2024, checked 27 September 2026) says a customer that ends the agreement before the initial term completes pays 100 percent of the subscription fees for the rest of that term within ten days. After the initial term, either party can end it with 30 days' written notice. Payments are non-cancelable and non-refundable. Negotiate the initial term length and an exit right tied to service failures.
Section 5.7 of the US terms requires customers to install Esker updates at least once every three years. The work runs under a separate SOW for an additional fee, done by Esker or a certified partner. A customer that does not update loses technical support and incurs an extra maintenance fee. Price these projects into total cost before signing.
The document storage and deletion policy in section 5 of the US terms says that, unless the archive service is purchased, processed documents stay on the platform for 60 days and are then erased. With archiving, customers can download archived documents themselves, but a bulk digital backup or an export tool needs a separate agreement and extra fees. Master data and configuration are deleted at the end of the agreement. Agree exit export terms at signature.
Esker's 9 September 2026 release on the Synergy Agentic Framework says external agents can reach Esker through APIs and standards such as MCP and A2A. On 27 September 2026 there was no Esker MCP server in the official registry, on GitHub or in Esker's docs. The public API is a SOAP web service for documents and transports. Get dates and scope in writing if agents are part of the plan.
Section 6.1 of the US terms says that once Professional Services change orders for one business process reach 40 hours or more, Esker adds up to 2 percent of the change order list price to the subscription fee to cover supporting the customization. The uplift recurs with the subscription. Keep configurations close to standard, or cap the uplift in the order form.
Esker's Technical Support Services page (dated 2022, checked 27 September 2026) sets standard support at 8:30 a.m. to 5:00 p.m. Central, Monday to Friday, excluding US holidays. Response goals are 2 hours for critical cases, 4 hours for degradation and 24 hours for minor issues, with resolution targets of 4, 48 and 72 hours. Local subsidiaries run their own support desks, so confirm coverage for each region in the contract.
Scored on what an outside agent can actually reach: the documented API, how it authenticates, and whether the vendor ships an MCP server.
Inside the product, Esker says Synergy AI (its AI engine dates from 2018) reads invoices without templates, learns layouts through a teaching feature, suggests coding, matches to POs and receipts and flags anomalies. Esker describes an Accounts Payable Agent that finds invoice information and speeds approvals, and conversational access through Microsoft Teams and Slack. Esker claims 80+ percent touchless invoices and 70+ percent fewer exceptions (vendor-claimed, AP page, checked 27 September 2026).
Exists: no. The official MCP registry, GitHub and Esker's documentation portal showed no Esker MCP server on 27 September 2026. The Synergy Agentic Framework release of 9 September 2026 says Esker can connect its workflows to enterprise AI through APIs and emerging standards such as MCP and A2A, with no documentation, scope or availability date. Treat it as an announcement.
Scope and turnkey do not apply yet. The only public API is the Esker on Demand Web Service, a SOAP interface documented at doc.esker.com (build of 2 June 2026) with session, submission and query services. The query service can approve, reject, update, cancel and resubmit transports, which are the platform's generic document records, and the docs describe no AP invoice, vendor or PO objects. Esker's ERP page mentions REST APIs, but no public REST reference was found.
For an AI agent today that means document-level automation through custom SOAP code, and nothing Claude can connect to without a developer. Ask Esker for dated commitments on REST and MCP access, their scope (read or write) and whether an admin must configure them.
Process a vendor invoice
Who wins for whom: Groups that want AP, procurement and supplier onboarding with tax ID and sanctions checks from one vendor: Esker. Global shared service centers processing 50,000+ invoices a year under e-invoicing mandates in several countries: Basware. Mid-market groups on Dynamics 365 or NetSuite that want four-eyes approvals and fraud checks inline: Medius.
Esker

Pay a vendor
Who wins for whom: Teams that want dynamic discounting and partner-run card and cross-border payments through Corpay, Stripe or LSQ: Esker. Enterprises whose ERP runs payments and that want payment dates written back to AP: Basware. Groups paying by SEPA, BACS, CHAPS or ACH from their own bank accounts inside the approval flow: Medius.
Esker
Esker Pay routes to partners. Esker moves no money itself: Esker Pay routes domestic, international and card payments, dynamic discounting and supply chain financing to fintech partners such as Corpay, Stripe and LSQ, and Supplier Management validates bank details first.
Where it loses: Supplier payment fees sit with Esker Pay partners such as Corpay and are not published, card rebates are not published either, and Esker runs no in-house payment rail.

Basware
Hands approved invoices to the ERP. Basware moves no money: approved invoices go to the ERP for payment, a PaymentResponses API writes the payment date back, and Trustpair bank-account checks await a deal signed 26 August 2026.
Where it loses: There are no ACH, check, virtual card or cross-border payout products, so rails, FX and card rebates need another tool, and Trustpair validates accounts without paying suppliers.

Where it loses: Per-rail fees are unpublished, the US card rebate is variable and not guaranteed under the May 2026 addendum, and Medius's two card pages disagree on expense card currencies.

Esker, kept current
Esker announced a governed agentic layer with Business Agents, Conversational Finance and connectivity it says will reach external agents through APIs, MCP and A2A. No documentation or availability date was published.
Esker announced its second year as a Leader in the Gartner report published 18 June 2026, and Leader status in The Forrester Wave for AP invoice automation, Q2 2026.
Esker integrated EcoVadis sustainability scores into supplier onboarding and evaluation, available to all Supplier Management customers.
A new module lets occasional buyers run RFQs for tail spend, with awards flowing into requisitions, purchasing and invoicing on the Esker platform.
Esker announced that France's DGFiP gave it final registration as a Plateforme Agréée, ahead of the 1 September 2026 mandate start (English release 13 January 2026). Esker says the platform is hosted in France and ISO 27001 certified.
QAD agreed to market Esker AP and other Esker solutions to its ERP customer base, with a pre-built integration and a progressive worldwide rollout.
Esker FAQ
Esker publishes no price, so the only reliable number is a written quote (checked 27 September 2026). Its financial releases show how it charges: a platform subscription plus transactional fees that track the volume of documents processed, with implementation billed on a separate statement of work.
Public benchmarks are thin. Vendr and SpendHound have no Esker page. Eco puts enterprise receivables suites including Esker at $100,000 to $300,000+ in year one (reported), a group band for order-to-cash suites that does not isolate Esker AP. As an Audit Friendly estimate, Esker's 2025 revenue of about 250 million euros across 3,000+ customers averages roughly 80,000 euros a year per customer across all modules and services. Ask for the per-document rate at your volume tier and the overage rate.
The US Terms of Service (last updated 30 August 2024) set the start date and initial term in the order form. Leaving before the initial term ends costs 100 percent of the remaining subscription fees; after it, either side can end the agreement with 30 days' notice. An update project is required at least every three years under a paid SOW.
Data export depends on archiving. Without the archive service, processed documents are erased after 60 days. With it, customers can download archived documents from the interface, but a bulk digital backup or an export tool needs a separate agreement and fees. Master data and configuration are deleted at the end. Write the exit export format, timing and price into the order form.
Esker Professional Services usually runs the project under a paid SOW, using an Agile method with incremental acceptance. Esker says its connectors can link an ERP in as little as five days and post a first Dynamics 365 or Sage invoice in about three days (vendor-claimed). The Aprolis story reports a two to three month go-live on Dynamics 365.
Partners also deliver: QAD markets Esker AP to its ERP customers (alliance of 3 September 2025), Numen supports SAP customers in the Americas, and B.Workshop builds JD Edwards and NetSuite links. On your side, plan for ERP and IT staff on connectors and master data, and super users who can spend real time testing.
Not directly, as of 27 September 2026. Esker has no first-party MCP server in the official registry, on GitHub or in its docs. The public API is the Esker on Demand SOAP web service, which lets custom code submit documents, query status and statistics, and approve, reject or resubmit transports, the platform's generic document records.
Esker's Synergy Agentic Framework, announced 9 September 2026, says external agents will be able to use selected Esker capabilities through APIs, MCP and A2A, with permissions governed inside Esker. No documentation or date was published. Inside the product, Esker says its agents already answer questions and trigger workflow actions such as approvals in Microsoft Teams and Slack.
