Invoice validation
Every invoice checked against its contract and purchase order, with the expected total, variances and potential savings.
AI tools for finance operations and procurement
Let AI read the contracts, invoices and purchase orders, and keep every decision with your team.
What I build
Software for finance and procurement
Contract clause extraction
Pricing, discounts, commitments and service credits pulled from contracts, each linked to its page and section.
Document intake
PDF, Word, Excel and scanned documents read and turned into structured data, with OCR where needed.
Approval workflows
Findings routed to the right person to approve or reject, with an audit log of who decided what.
Audit-ready reports
Non-editable PDF reports with timestamps, versions, results and explanations, ready for auditors.
Finance dashboards
Revenue, collections and supplier accuracy in one view, from the same data the checks use.
AI, right now
Where AI genuinely helps
Finance and procurement teams sit on piles of documents that decide real money: contracts, purchase orders, invoices. Checking each invoice against its contract properly is slow, so it mostly doesn’t happen, and overcharges go unnoticed.
AI can now read those documents reliably enough to do the first pass, as long as people stay in charge of the decisions. PayRight is built on exactly that rule, and OpsVanta shows the finance side of a full operations platform.
Reading documents at scale
AI extracts the clauses and line items that matter, so people review findings instead of reading every page.
Catching what slips through
Pricing variances, quantity mismatches and missed discounts flagged before payment, not found in an audit later.
Plain-language summaries
Each finding explained in a sentence an approver can act on, with a link to the source.
Human in the loop by design
AI identifies, a person confirms, the system calculates. Nothing is approved or paid automatically.

Data, security and access
- AI never approves, blocks or changes a payment; it recommends and people decide.
- Every finding traces back to the document, page and section it came from.
- Role-based access, per-customer data separation and audit logs across every critical action.
- Benchmarks use anonymised, derived figures, so no customer's financial data is shown to another.

Questions
Common questions
Will the AI approve or pay invoices automatically?
No. It's a decision-support tool. AI extracts and compares, the system calculates, and a person approves or rejects every result.
What kinds of documents can it handle?
Contracts, purchase orders and invoices as PDF, Word, Excel, CSV or JSON, including scanned copies, which go through OCR first.
How do you make AI output trustworthy for finance?
Every extracted clause shows its source, people confirm clauses before they're used, and results are reproducible from the stored data. Before go-live, results are checked on a sample of your own documents.
Can it connect to our ERP or accounting system?
Usually through the system's API or regular exports. Which systems, and how, is set in the scope after a call.
Checking invoices and contracts by hand?
A 30-minute call is enough to tell whether it fits, what the first version should include, and how long it takes.
