Contract Compliance Audit01

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 Friday01

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 costs02

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

What we have measured inside vendor-invoice-heavy AP organizations. Your numbers will differ — the two-week audit puts figures on yours before anything gets built.

3,000Invoices a day through one AP inbox — a sampling firm reads a fraction, once a year

How it works03

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

    Every invoice and vendor statement is read and checked against the encoded terms before payment runs — the rate, the escalator date, the unit of measure, the surcharge math. Violations land in a review queue.

    Weeks 3–8
  3. 03

    Run it every payment cycle

    The audit keeps pace with the inbox: price creep flagged on the first invoice it appears on, earned rebates claimed inside their windows, a compliance report your controller can take to the vendor.

    Ongoing
Not another tool

Recovery firms sample last year. Encoded terms check every bill this week.

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.

Contract software stores the PDF and reminds you at renewal; it never checks a single invoice against the terms. We are neither: we encode your contract terms as rules, and our AI checks every invoice and statement against them before payment — contract compliance audit services as a continuous control, at a fixed fee.

Questions04

Asked by controllers and CFOs.

The straight answers, before you book anything.

A contract compliance audit checks whether your vendors are actually billing to the terms you negotiated — the rates, escalators, rebates, surcharge tables, and pass-through clauses in the signed contract and its addendums. It is not a legal or regulatory compliance review; it is the commercial question of whether the invoice matches the agreement. Traditionally it runs once a year on a sample. Ours runs continuously, on every invoice, before payment.

Recovery firms audit a sample of last year’s payments, charge a percentage of what they claw back, and leave — the leak reopens with the next invoice. We encode your contract terms as rules and check every invoice and statement against them before the money leaves, for a fixed fee. If you also need the backward-looking sweep to recover what was already overpaid, that is our AP recovery audit engagement; this is the always-on layer.

Contract lifecycle management tools store the documents, track renewal dates, and manage signatures. None of them reads this month’s invoices against last year’s addendum. We encode the terms themselves as rules — which addendum wins, which escalator applies when — and the audit runs inside the AP flow you already have. Your team sees a review queue, not a new system.

Your vendor contracts and addendums, read access to the invoice feed or AP export, and two hours a week with whoever knows the terms. The two-week audit maps your top vendors’ terms and prices the drift before you commit to a build.

The two-week audit is a fixed fee, credited toward the build if you continue. Builds are scoped per vendor portfolio with a payback estimate up front — no percentage of recovery, no per-seat license.

You do. The rule set — every rate, escalator, rebate tier, and surcharge table we encoded — is documented and handed over, and anything we built keeps running. There is no lock-in designed into the work.
