AI-powered contract-to-payment assurance
Vendor Optic’s AI reads your contracts and turns every pricing term into a plain-language rule. Proprietary machine-learning models learn how each vendor bills, so every invoice line is checked before the payment run, and every overcharge comes with the clause, the invoice line and the math.
Vendor Optic reads from these systems. Product names are trademarks of their owners; no endorsement implied.
The problem
The evidence is scattered across scans, spreadsheets and inboxes, far too much to check by hand. Vendor Optic’s AI reads all of it
The AI engine
Rules catch what the contract says. Proprietary machine-learning models catch what rules miss. Together they check every invoice line before you pay.
Reads scanned and native contracts, amendments and rate cards like an expert analyst, and extracts every price, rate, cap, discount and effective date.
Proprietary models learn the normal billing pattern of each vendor, role, lane and item, and flag anything that breaks it, even when no rule covers it.
Each approval, hold and dismissal your team records sharpens the models, so findings get more precise with every payment run.
Every model runs inside your environment and never trains on anyone else’s data. Every finding shows the clause, the invoice line and the math.
The 360 view
One AI platform, from the contract, to every invoice, to the payment, to the money back, to the renewal, and around again.
Document AI reads contracts, amendments and rate cards, scanned or native, and works out what each file is and which vendor it belongs to.
The AI turns every pricing term into a sentence a person can check. A named person on your team approves the rulebook.
Every line is checked against the rules in force on the date the work was done, and scored by models trained on each vendor’s billing patterns, before your payment run.
The AI recommends: hold, query the vendor or send to the contract owner. A person always decides.
AI-drafted disputes and credit claims are tracked until the money is actually back.
Walk into every renewal with an AI-built scorecard, the overcharges by cause and the clause weaknesses ranked by cost.
How it works
No sorting. The AI classifies every file and matches it to the right vendor and contract.
The AI turns each pricing term into a plain-language rule linked to the exact spot in the contract. Nothing is used until a person on your team approves it.
Against the rules in force on the date the work was done, including every amendment, while machine-learning models flag anything that breaks the vendor’s usual pattern.
Approve, hold and query the vendor, send to the contract owner, or dismiss with a reason. Every decision teaches the models, and recoveries are tracked until the money is back.
Accepted formats: PDF, Scanned PDF, Word, Excel, CSV, Email, ZIP, EDI, e-invoice XML.
From 1 April 2026 to 31 March 2027, a Programmer Analyst at Level 2 is billed at $145.00 per hour
See the proof
Illustrative example
This invoice bills a Level 3 Programmer Analyst at $175.00 per hour. The contract, as amended on 1 April 2026, sets Level 3 at $160.00 per hour. The difference on 120 hours is $1,800.00.
Schedule B is amended by replacing the rate for Programmer Analyst, Level 3, with $160.00 per hour, effective 1 April 2026.
This is 1 of 7 similar findings: 7 invoices billed the pre-amendment rate, $12,600.00 in total.
What the AI catches
Money owed to you
Illustrative example
Invoice checking alone never sees this money. Vendor Optic’s AI does
Coming up
Illustrative example
For your role
See every dollar you were overcharged, and get it back, with proof your auditors accept
The prices you negotiated, enforced on every invoice
Know which vendors bill accurately, and walk into every renewal with the numbers
Your contracts, finally working after signature
Ask a contract
Answers come only from your contracts, with the citation. If the contract does not say, the AI says so instead of guessing.
Illustrative example
Coverage you can see
You always know what is checked, what is not, and what it's worth.
Illustrative example: The AI found 212 lines worth $184,000.00 for detention charges that no rule checks yet. Clause 14.3 in three contracts appears to govern them.
Start safely
The AI checks past invoices against your contracts. (No system access needed)
The AI records what it would have held. (Touches nothing)
A list for AP before each payment run. (No system access needed)
Sets the hold itself, for clear-cut cases only.
Each step is optional.
Trust and control
The AI and its models run in your AWS or Azure account, your data centre or a disconnected network. No document leaves your organization, and your data never trains anyone else’s models.
The AI recommends; it never pays, approves or rejects anything. At most it places one payment hold, with a reason.
If Vendor Optic is down, slow or unsure, invoices flow exactly as they did before.
Signed, tamper-evident evidence packs that reproduce identically a year later.
Masked before the AI reads any document. Access to unmasked data is permissioned and logged.
Every screen, rule and report in English and French. WCAG 2.2 AA in both themes.
It sits between the contract system and the payment system and makes sure they agree.
Explainable AI, not a black box: every result shows the clause, the invoice line and the math.

Value estimator
Annual spend × share under contract = spend checked. Spend checked × your assumed overbilling rate = estimated overbilling.
This estimate uses only your own assumptions. It is not a promise of results.
FAQ
Yes. Document AI reads your contracts and invoices, and proprietary machine-learning models learn each vendor’s billing patterns to flag what rules alone would miss. Every finding is explained with the clause, the invoice line and the math, and a person makes every decision.
The models learn from the patterns in your own contracts, invoices and decisions, inside your environment. Your data never leaves your organization and never trains models for anyone else.
No. Vendor Optic never pays, approves or rejects anything. At most it places one payment hold, with a reason, that a person releases.
No. Vendor Optic runs inside your own cloud account, your own data centre or a fully disconnected network. No document, number or result leaves your organization.
Invoices flow exactly as they did before. An uncertain result goes to a person and never blocks a payment.
Yes: skewed scans, stamps over tables, rate tables across many pages, handwritten or initialled changes, and contracts of 500 pages or more.
No. Vendor Optic reads from SAP, Oracle, Coupa, Dynamics 365 and others. It writes exactly one thing: a payment hold with a reason code.
French and Spanish invoices are read like any other. Every screen, rule, evidence pack and report is available in English and French.
A named person on your team. Nothing is used until a person approves it, and each rule links to the exact spot in the contract.
A signed, tamper-evident evidence pack for every finding and a full audit trail of who changed what, when and why.
Yes, without programmers. A second person approves every extension before it goes live.
Most teams start with a retrospective review of past invoices, which needs no system access. Results depend on your contracts and invoices.
