PROBLEM
The overcharges don’t look like overcharges.
The overcharges don’t look like overcharges.
A rate creeps past the escalation cap. A charge appears that the contract prices lower, or doesn’t allow at all. A fee repeats month after month.
Nobody is reading line items against contract language by hand, not across thousands of units. So the drift never surfaces.
It just leaves, every billing cycle.
HOW IT WORKS
Three steps. No integrations.
Three steps. No integrations.
Step 1
Onboard
You send us your contracts and 12 months of invoices to start. We set up a letter of authorization with each vendor, and from then on their billing comes to clauseback directly.

Step 2
Reconcile
The engine pulls the governing terms out of each contract, rates, escalation caps, permitted charges, then reads every line on every invoice against the terms that govern it and quantifies each discrepancy to the dollar.

Step 3
Recover
Where billed diverges from agreed, you get a finding: the overcharge, the clause it breaks, and the documents behind it, assembled into a recovery schedule you can send the vendor.
