Overtrace vs. AP automation: what’s behind the invoice, not just on it.
AP automation tools like AppZen, Vic.ai and Stampli are built to process invoices at volume — capture, coding, approvals, PO matching and anomaly detection. A T&M invoice is different: the total is only right if thousands of pages of timesheets, equipment lists & receipts behind it are right. That’s what Overtrace audits.
Why teams choose Overtrace
Why construction teams add Overtrace to AP.
Reads the backup
Field-signed T&M, sign-in sheets, equipment lists & receipts — scanned, handwritten or typed — reconciled against the billing detail.
Construction rules built in
Overtime after 40 straight-time hours, equipment on no-crew days, per diem eligibility, monthly equipment rates — the checks a T&M package needs.
Every finding cited to its page
Billed line, supporting record and the deciding number boxed on the page image. The trade, the client and the auditor can all check it in seconds.
Runs before AP
Audit the package first; send AP an approved amount with the disputes documented.

Questions
Common questions.
Do we still need AP automation?
Probably — it’s good at what it’s built for. Overtrace sits before it on T&M billing: it audits the package, and AP pays the amount you approve.
Does Overtrace integrate with our AP system?
Today Overtrace exports Excel workbooks and PDFs that can be attached to any approval workflow. Tell us what you use and we’ll talk about what’s next.
