The Problem
Invoice overbilling is the most common procurement loss — and the hardest to catch manually.

The average construction project receives 200+ invoices. Checking each one against its PO takes 5–15 minutes per document — hours every week. Most teams don't catch rate drift until the project closes. Trueleveler cross-references every line in seconds and flags everything that doesn't match, including charges that were never in the original scope.

34%
of construction invoices contain at least one pricing error or unauthorized charge*
