For multi-site AP teams

Your supplier invoices are wrong.
You just don't know yet.

Quantize reads every supplier invoice against the contract you signed and flags what's wrong - before the payment leaves.

No catch fee. We get paid when you recover money.

The contract clause, attached to the invoice line.

Every flagged line carries the exact clause that proves it - so the credit-note conversation with your supplier is already won.

Without vs with

The AP team's day, before and after.

Without Quantize
  • • Pricing errors surface 4-9 months late, if at all.
  • • Contracts buried in someone's Drive, never re-opened.
  • • Refunds chased one supplier email at a time.
  • • Quarterly rebates missed because nobody tracks the threshold live.
With Quantize
  • ✓ Alert in your inbox the day the price drifts.
  • ✓ Clauses extracted once, checked on every invoice forever.
  • ✓ Credit-note email drafted per supplier, ready to send.
  • ✓ Rebate progress live, not discovered at year-end audit.
The active agent

Your contracts have clauses.
Nobody's enforcing them.

Price caps, rebate thresholds, indexation, annual reductions. They sit in a contract PDF and never make it to the invoice queue. Quantize is the agent that watches every clause against every invoice, the day it lands.

Price-adjustment caps

Contract says CPI+3%. Supplier billed +8%. Caught on the first invoice, not at year-end.

Volume rebates

3% kicks in at £500k spend. We track the threshold live, so the kickback isn't claimed two years late.

Annual price reductions

Laptop refresh contract drops 4% every Jan 1. Applied on invoice one, not 18 months in.

Indexation clauses

Tied to a published index? We re-check the index every month and flag the gap.

Maverick spend

Invoice with no PO, from a supplier with no agreement on file. Flagged before approval.

Payment terms

Contract says net-60. Supplier dunning at day 30. Held with the clause attached.

Beyond overcharges

Errors used to expose you. Not anymore.

The same engine that reconciles invoices against contracts also catches the things you don't want hitting your bank: duplicates, sudden IBAN swaps, first-time payees with no agreement on file.

Duplicate invoice

Same invoice number, different week. Caught before it leaves your AP queue.

Bank-detail change

Supplier IBAN suddenly changed? Flagged against the agreement on file.

Unknown payee

First-time supplier, no contract, payment requested. Held for review.
