Travel-agent and GDS commission reconciliation follows the same principle as OTA commission review: the valid commission amount depends on the final eligible stay.
What changes the commission base
Cancellations, no-shows, early departures, shortened stays, rate-code eligibility and other supported modifications can change whether commission is due and the revenue base used to calculate it.
Matching matters
Reservation IDs, agency references, IATA numbers, stay dates and financial amounts help connect the commission payment with the hotel-side stay.
Recovery should remain deterministic
The expected amount should be reproducible from the final stay, commissionable revenue and valid rate. Ambiguous matches belong in review, not automatic external recovery.
