Follow one new vendor from the first request to a verified record you can pay. Turn the dial to see what AI takes off your plate at each step, what it hands back to you, and which tools do it today.
Some tools let an assistant like Claude read your vendor contracts directly. Vertice hosts its own connector, and Tropic has one an admin switches on.

One lesson every few days, each a four-minute read with one small thing to try that week. It starts with the jobs almost every business has: paying bills, payroll and the month-end close.
The last lesson links back to this walkthrough and the other seven.
Today. Someone emails finance a quote and asks to add the vendor, with no owner, budget or reason attached.
With AI. Drafts the intake from the documents, points to preferred or existing vendors, and routes it to the right approvers. In: a plain-English request and the vendor's quote. Out: a complete request with an owner, a reason and its approvers.
Who decides. AI-assisted: AI drafts the request, the requester confirms it. AI-run: Complete requests route themselves, gaps go back to the requester.
Control. Every vendor starts with a request that names an owner and a reason.
Tools that do this. Ramp (score 85): the Procurement add-on takes plain-English requests and routes parallel approvals to finance, IT and legal. Procurify (score 72): Guided Intake drafts the request from a plain-language description (paid add-on). Vertice (score 77): conversational intake, with compliance and legal agents that check requests against policy. Zip (score 80): AI Procurement Concierge pre-fills intake from uploaded documents and steers requesters to preferred suppliers.
Today. Email the vendor a form, wait for a scan to come back, and retype it into QuickBooks.
With AI. Sends the vendor one secure form for tax, bank and payment details, and checks it is complete before it comes back. In: the approved request and the vendor's email address. Out: a complete vendor profile, entered once by the vendor.
Who decides. AI-assisted: The vendor fills the form, finance reviews it. AI-run: Complete forms move on, gaps go back to the vendor.
Control. Bank and tax details come in only through the secure form, never by email.
Tools that do this. Tipalti (score 82): suppliers onboard themselves and pick a payment method and currency. Routable (score 72): vendors submit tax forms in a branded flow without creating an account. BILL (score 78): vendors already on the BILL network get paid without anyone collecting their bank details. PaymentWorks (score 71): one registration covers tax, banking, insurance and conflict-of-interest data.
Today. Chase W-9s by email, file the PDFs, and find the bad tax IDs in January.
With AI. Requests the right form, checks the tax ID against IRS records, and flags mismatches. In: the vendor's W-9 or W-8. Out: a verified tax form, or a flag with the reason.
Who decides. AI-assisted: AI collects and checks, a person approves each form. AI-run: Verified forms approve themselves, mismatches go to a person.
Control. Hold payment until the vendor's tax form is verified.
Tools that do this. BILL (score 78): W-9 Agent emails new vendors, collects W-9s and validates tax IDs, and approves high-confidence forms. Melio (score 73): requests W-9s by email, validates tax IDs and totals payments against the 1099 threshold. Tipalti (score 82): a tax wizard picks the right form and applies 1,000+ rules, including TIN matching. Trolley (score 73): matches tax IDs against IRS records and re-requests W-8 forms when they expire.
Today. Copy the bank details off the vendor's PDF and trust that they are real.
With AI. Validates the account and its ownership against official and network data, and screens against sanctions lists. In: the bank details and the vendor's company record. Out: a verified account, or a hold with the reason.
Who decides. AI-assisted: AI checks, a person clears every flag. AI-run: Clean checks pass, risky ones are held for a person.
Control. Unverified bank details block payment until they clear.
Tools that do this. Tipalti (score 82): validates bank details against 26,000+ rules before the first payment. Lightyear (score 68): a Bank Details Checker compares the details on a bill with the supplier record. Trustpair (score 72): checks company and bank data against official sources and escalates risky cases to a person. PaymentWorks (score 71): identity and bank-ownership checks, with sanctions screening at onboarding and afterward.
Today. Create the vendor in QuickBooks by hand, often next to an old record for the same company.
With AI. Matches the new vendor against existing records by tax ID and name, and flags likely duplicates. In: the verified profile and your existing vendor list. Out: one vendor record, or a suggested merge.
Who decides. AI-assisted: AI flags likely duplicates, a person decides. AI-run: New vendors with no match are created, matches go to a person.
Control. One vendor record per tax ID, with every change logged.
Tools that do this. PaymentWorks (score 71): Registration Routing matches new submissions to existing ERP records by tax ID to avoid duplicates. Ottimate (score 76): Trust Score flags first-time vendors and duplicate invoices before payment. Xelix (score 69): scans the vendor master daily for duplicate, inactive and incomplete records. Trustpair (score 72): re-evaluates every vendor in the master file and suggests corrections.
Today. Whoever is around says yes, often the person who asked for the vendor.
With AI. Summarises the request, the tax and bank checks and any flags on one card, and routes it to the approver. In: the request and the results of every check. Out: a one-tap approval with every check in view.
Who decides. AI-assisted: A named approver decides, with every check in view. AI-run: A named approver decides, always.
Control. The requester can't approve their own vendor, and bank changes need a second approver.
Tools that do this. ApprovalMax (score 72): the requester can be a condition in the approval rules, so nobody signs off their own request. Payhawk (score 80): changes to supplier bank details can require a second approver. Ramp (score 85): routes parallel approvals to finance, IT and legal before a PO exists.
Today. Nothing happens until something goes wrong: an expired form, a sanctions hit, a bank change by email.
With AI. Re-screens vendors over time, re-requests expiring forms, and re-verifies every bank change. In: your vendor list, tax forms and change requests. Out: a current vendor list, with risky changes held for a person.
Who decides. AI-assisted: AI flags changes, a person reviews each one. AI-run: Routine updates go through, risky changes go to a person.
Control. Every change to a vendor's bank details gets the same checks as a new vendor.
Tools that do this. PaymentWorks (score 71): screening continues after onboarding, and a status change triggers an alert. Trolley (score 73): re-requests W-8 forms when they expire. Stampli (score 80): a vendor portal for status and documents (add-on), and bank changes go through review first. Xelix (score 69): alerts on bank-account changes and new vendors.
“Here are our W-9 and bank details. Can you set us up?” Replies with the secure registration link and keeps the emailed bank details out of your records. AI-run sends the reply. AI-assisted drafts it for finance.
“Is Brightline Cleaning already a vendor?” Searches the vendor list by name and tax ID and reads the onboarding status. AI-run sends the answer. AI-assisted drafts it for finance.
“The CEO needs this vendor paid today. Can we skip the checks?” Never skips a check. Flags the urgency and routes the request to a person. The controller, always.
Tools that do this. Tipalti (score 82): suppliers onboard themselves through a portal and pick how they get paid. Stampli (score 80): a vendor portal for status and documents (add-on), with bank changes reviewed first. Vertice (score 77): with its MCP connector, Claude can open a purchase request and asks before acting. Zip (score 80): AI Procurement Concierge pre-fills intake and steers requesters to preferred suppliers.
Put in your own figures. The result is labour only, and you choose how much of the work you expect AI to take on.
We don't show an industry benchmark here, because we haven't found a current, independent figure for what vendor setup costs.
