CheckIT Invoice • AP VerificationWhat did you pay vs. what you agreed?

The invoice your vendor sent isn't the invoice your contract priced.

Drag in the invoice. Drag in the quote. CheckIT reads every line and shows you every difference — unit prices off-contract, quantities you didn't order, charges that aren't in the quote at all. One click drafts the dispute. Five minutes from upload to resolved. Live with pilots — every one found money in week one.

5-minute setup • No integration • No IT • Drag, drop, done

FLAGGED — OFF-CONTRACT

One tool on the CheckIT engine. The first one we built. Not the last.

CheckIT Invoice answers the last money question on every job: what did you actually pay, versus what you agreed? The same engine is coming for the other two — CheckIT RFQ for what should you pay (beta Q3 2026) and CheckIT Estimate for what will it cost (design partners forming, 2027), with Change Order validation in between (H2 2027). Start with Invoice. The rest roll out on the same engine, same drag-drop interface, no new sales motion.

Your AP team is doing the job five tools already failed to do.

Your ERP records the budget. Accounting cuts the check. AP automation routes the invoice. PM tracks the schedule. None of them check whether the numbers on the invoice match the deal you actually signed. So a PM screenshots the invoice out of the ERP, pulls it into Bluebeam, compares it against the quote line by line, emails finance, who uploads it to the AP tool — and then chases the vendor for a credit over email for the next two weeks.

Every invoice. Every time. 45 to 60 minutes per document. And the ones nobody had time to check? Those just get paid.

How it works

Five seconds to learn. Five minutes to set up. Done.

  • Drag

    Pull the invoice and the quote into CheckIT. PDF, image, Excel — doesn't matter. Your documents, as they are.

  • Drop

    Anywhere on the screen. No folders. No formatting requirements. No template setup.

  • Process

    The engine reads every line and finds every difference. Unit prices off-contract. Quantities overbilled. Charges that aren't in the quote. Each flag shows the exact dollar impact and the source.

  • Generate

    One click drafts the dispute email with the line items, dollar amounts, and source evidence attached. Edit it if you want. Send it.

  • Done

    Profit saved. Hours back. Audit trail logged. Move on to the next job.

Built for the people doing this work today.

  • Owners and Principals

    You don't read invoices line by line. You read the dashboard. Vendor performance. Recovered margin. Project exposure. The first time the math lines up with what you actually agreed to.

  • Project Managers

    You're the one reconciling material tags against supplier invoices at 9pm. CheckIT does that work in minutes — and the flag includes the exact line and dollar amount so the dispute writes itself.

  • AP, Controllers, and Bookkeepers

    You're the last line of defense for errors nobody else had time to catch. CheckIT moves you from defense to verification — every invoice cross-checked before it hits the approval queue, every dispute logged. Get your evenings back.

Every line. Every time.

  • Unit prices off-contract

  • Quantities billed beyond what was delivered or installed

  • Charges that aren't in the quote at all

  • Arithmetic errors — subtotals that don't add up

  • Wrong tax rate for the job location

  • Invoiced amounts that exceed the approved change order

  • Equipment rates above the rental agreement

  • Cumulative pricing drift across a multi-month job
