LiftAI’s AI invoice review doesn’t judge an invoice in a vacuum — it compares each invoice against the property’s contract. The more accurate and complete that contract is, the more overcharges the review can catch. This article explains the connection so you know what to keep up to date.
The AI invoice review is rolled out gradually and depends on the contract having structured pricing. If the review can’t run for an invoice, see Why isn’t AI invoice review available?.

What the review reads from the contract

When the AI reviews an invoice, it draws on the contract’s:
  • Pricing — the monthly price and the rate sets (hourly rates for billed labor). Without structured pricing, there’s nothing concrete to compare line items against, and the review can’t run.
  • Review rules — what the contract says is included, excluded, a miscellaneous charge, or otherwise worth flagging. These let the review tell a covered service apart from one that shouldn’t be billed separately.
  • Terms — such as escalation caps and parts-and-materials markup, which the review uses to check whether amounts are within the contract.
Where the review relies on the contract, its findings cite the specific clause — so an accurate contract also makes each finding checkable. See Understand the AI invoice review.

Why completeness matters

A thin or out-of-date contract limits what the review can find:
  • Missing pricing means the review can’t run at all for that property’s invoices.
  • Missing or wrong review rules mean the review has no basis to flag a charge that the contract actually excludes — so an overcharge can slip through.
  • Stale rates or terms can make legitimate charges look wrong, or wrong charges look fine.

Keep contracts review-ready

1

Check eligibility

Open the contract and look at the AI Extraction card on the Overview tab. The Invoice review eligible chip tells you whether the contract is ready. See View contract details.
2

Fill in pricing and rules

Make sure the contract has its pricing (a monthly price and/or rate sets) and its review rules. See Edit a contract.
3

Keep it current

Update rates, terms, and rules whenever the contract changes, so the review always compares against today’s terms.
