CheckIT Invoice • Invoice Verification — What 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. Most of those errors never look wrong on the invoice by itself; they only show up next to the quote. That's invoice verification against the deal you actually signed. One click drafts the dispute. Five minutes from upload to resolved. Live with customers — every one found money in week one.
5-minute setup • No integration • No IT • Drag, drop, done
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? That's invoice verification — every supplier invoice checked against the quote, line by line, so pricing and quantity errors surface before the check goes out. The same engine is coming for the other two — CheckIT RFQ for what should you pay (invite-only pilot) 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 do the actual invoice verification — checking whether the numbers on the invoice match the deal you actually signed, which is the only place a billing error ever shows up. 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 get paid with the errors still in them.

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 checking 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 error. 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

Invoice verification, answered.
Invoice verification is checking a supplier's invoice against the price you actually agreed to — the quote — line by line, before you pay it. CheckIT Invoice reads both documents and flags unit prices off-contract, quantities you didn't order, and charges that aren't in the quote at all, with the exact dollar impact and source for every flag.
The most common errors are unit prices that drifted off the quote, quantity and unit-of-measure mismatches (the quote priced per foot, the invoice bills per case), charges and surcharges that were never quoted at all, substitutions billed above the price of the item they replaced, duplicate lines and duplicate invoices, and arithmetic mistakes where the extensions and subtotals don't add up. Industry data puts at least one error on 39% of construction invoices, with average overbilling running 2.5% of invoice value. Almost none of these errors look wrong on the invoice by itself — they only surface when the invoice is checked against the quote line by line, which is what CheckIT Invoice does.
AP automation routes invoices for approval. Three-way matching checks the invoice against a purchase order and a receipt. Neither checks the price. CheckIT verifies the invoice against the quote — the price the supplier actually committed to — which is where material overbilling hides. 39% of construction invoices contain at least one error, and the average overbilling runs 2.5% of invoice value.
No. CheckIT works on its own from day one — drag in the invoice, drag in the quote, done. Integrations with Sage, Foundation, Viewpoint, Plexxis, Procore, and QuickBooks are optional accelerators for pushing approved invoices into your accounting system. They are never a prerequisite.
About five minutes. There's no IT project, no template setup, and no integration required. Drag in your first invoice and quote and you're verifying.
