Portion of Amazon's payable that Amazon withholds against future refunds and chargebacks. Not realized proceeds until released in a later settlement.
Reserved Amount — sometimes called Payment Reserve or Balance Reserve — is the portion of your Amazon receivables that Amazon withholds for a rolling window (typically 7-14 days) to cover potential refunds, returns, chargebacks, and A-to-Z claims. It appears as a negative line in the current settlement and a positive release in a later settlement.
Reserve amounts are typically calculated as a percentage of unshipped orders, in-transit orders, or recently shipped orders, depending on your seller history.
Settlement N: Amazon withholds INR X → current-reserve-amount = -X
Settlement N+1: Amazon releases the previously withheld amount → previous-reserve-amount-balance = +X (and withholds a fresh amount for this cycle)
The two rows work together across consecutive settlements.
Sellers frequently make one of two mistakes:
Correct treatment: book reservations as suspense entries, then recognize the release row as realized against the shipping bills whose orders originally contributed to the reservation.
Getting reserved amounts wrong is the #3 reason AD Banks reject reconciliations — see 8 reasons AD Banks reject FBA EDPMS closures. For the field-level view of how these rows appear in the settlement TXT, see anatomy of an Amazon settlement report.
