Contract Compliance Audit

Contract compliance audit without the once-a-year sample.

We encode your vendor contracts — rates, escalators, rebates, surcharge tables, pass-through clauses — into rules, and every invoice and statement gets checked against them before payment runs.

The broken Friday

The contract says one number. The invoice says another.

From finance and operations teams we have sat inside: PE-backed services businesses running hundreds of vendors, where the terms live in a PDF library and the bills keep coming anyway.

  • Rate creep nobody sees until the quarterly review

    There is no line-level pricing history, so a vendor price increase slides through invoice by invoice and quietly compresses margin — found at the quarterly review, five months late, when recovery means an awkward call.

  • Case price, each price — the overcharge hides in the unit

    Weekly medical-supply invoices bury overcharges in unit-of-measure ambiguity; somebody has to know the item to catch it — at a multi-state hospice provider buying across dozens of facilities.

  • The escalator applied early, late, or twice

    The contract says CPI-adjusted each January. The invoice jumps in October, or the same surcharge climbs twice. Nobody re-reads the clause mid-contract, so the drift compounds.

  • Rebates earned under the contract, never claimed

    The volume tier tripped in Q2; the claim window closed in Q3. What the agreement says you earned lives in a PDF, not in the ledger — so it surfaces at renewal, short or never.

  • Insurance and certification requirements, filed and forgotten

    The contract requires a current certificate of insurance and the right licenses per site. They expire quietly, the bills keep getting paid, and the requirement only surfaces when something goes wrong.

What manual costs

A sampled audit prices last year. The drift runs this year.

Reported operating examples show where manual work adds up. Your audit establishes the workload, error rates, and costs in your business.

How it works

We encode the contract.

No new system for your team to learn. The terms your best person carries in their head become the rules every invoice and statement is checked against.

  1. 01

    Map the terms

    We pull the terms out of your contracts and addendums — rates, escalators, rebate tiers, surcharge tables, pass-through clauses, insurance requirements — and write them down as a rule set. Yours to keep.

    Weeks 1–2
  2. 02

    Encode the audit

    Build checks for the available invoices and vendor statements against agreed terms, including rates, escalator dates, units of measure, and surcharges. Test coverage and route uncertain results for review.

    Weeks 3–8
  3. 03

    Run it every payment cycle

    Run the agreed checks each payment cycle and route potential rate changes, rebate opportunities, and compliance discrepancies for review. Timing and coverage depend on current terms and available invoice data.

Not another tool

Contract checks within your AP workflow.

A contract compliance audit from a recovery firm means sampling a slice of last year’s payments, taking a percentage of what it claws back, and leaving the contract exactly as unaudited as before. The drift resumes with the next invoice.

We can encode contract terms into checks within your AP workflow. The scope defines the source documents, invoice coverage, review cadence, and human approval requirements.
