What Is Pre-authorization? Definition, Payment Flow, and Examples
Pre-authorization places a temporary hold before the final amount is known and is common in hotels and car rentals. This guide focuses on Pre-authorization's real role, boundaries, and common points of confusion.
Key points
- Definition: Pre-authorization places a temporary hold before the final amount is known and is common in hotels and car rentals.
- Flow position: A pre-authorization establishes an approval basis for an estimated transaction, an incremental authorization adds an allowed amount, a partial authorization approves less than requested, and a reversal tells the issuer to cancel all or part of the original authorization.
- Do not confuse: Pre-authorization / Incremental Authorization
How it fits into the payment flow
For Pre-authorization, the relevant process is as follows: A pre-authorization establishes an approval basis for an estimated transaction, an incremental authorization adds an allowed amount, a partial authorization approves less than requested, and a reversal tells the issuer to cancel all or part of the original authorization. Follow-on messages must link correctly.
A practical review of Pre-authorization should account for this: these patterns are common in lodging, vehicle rental, cruises, and other estimated-amount businesses, but eligible categories, timing, and message fields are network-specific rather than universal.
Practical example
At check-in, a hotel places a pre-authorization for estimated charges and later captures or adjusts to the final amount. The initial hold is not a completed final charge.
How it differs from related terms
| Term | Definition |
|---|---|
| Pre-authorization | places a temporary hold before the final amount is known and is common in hotels and car rentals |
| Incremental Authorization | requests additional authorized amount when the expected total grows beyond an earlier pre-authorization |
| Capture | is the merchant's confirmation after authorization that submits the transaction toward clearing; it is not completed interparty settlement |
Pre-authorization focuses on the fact that it places a temporary hold before the final amount is known and is common in hotels and car rentals. Incremental Authorization, by contrast, requests additional authorized amount when the expected total grows beyond an earlier pre-authorization. They can appear in one transaction while answering different questions.
Use cases and limits
A key limit of Pre-authorization is the following: A missing or mismatched reversal can leave a hold in place longer. Treating an increment as an unrelated purchase can also create reconciliation and customer-explanation problems.
