# Why isn't AI invoice review available?

> Why the AI invoice review can't run for an invoice and what's needed to enable it.

If the **AI Review** tab shows an "Unlock AI Invoice Review" panel instead of a result, the AI review can't run for that invoice yet. This is expected — it just means the property doesn't have the pricing data the review needs to compare against.

## What the AI review needs

The AI review only runs when the invoice's property has a contract with **structured pricing in effect on the invoice's service date** — either:

* at least one **rate set**, or
* a **monthly price** on the property's contract.

Review rules on their own aren't enough. Without underlying pricing, there's nothing concrete for the AI to compare the invoice's line items against, so the review can't produce a useful result.

## Common reasons the review is blocked

* **No contract on file for the property.** Nothing for the review to compare against.
* **The contract has no structured pricing.** A contract exists, but it has no rate sets and no monthly price.
* **The contract didn't cover the invoice's service period.** The contract had expired, hadn't started yet, or was otherwise inactive for the dates the invoice was issued for. Even if the property has a current contract today, the review uses the contract that was in effect when the work was billed — so a gap between contracts will block the review for invoices in that gap.

<Note>
  When you see the unlock panel, reach out to your LiftAI Account Executive. They can help get the contract's pricing set up — or backfill a contract that covers the invoice's service period — so the review can run.
</Note>

The AI invoice review is also rolled out gradually, so it may not be turned on for your account yet. Your Account Executive can confirm where things stand.

## Once it's enabled

When the property has an active contract with structured pricing, opening the **AI Review** tab generates a recommendation automatically. To learn how to read it, see [Understand the AI invoice review](/invoices/ai-invoice-review).
