Void
What Is a Void in Payments? Definition and How It Works
Definition
A void in payments is the cancellation of an authorised but not yet settled transaction, releasing the authorisation hold on the cardholder's account before any funds have moved.
How it works
A void can only be performed on a transaction that has been authorised but not yet captured and settled. Once a transaction has been captured and included in a settlement batch, it cannot be voided, at that point only a refund can reverse the funds.
Voiding releases the authorisation hold immediately in most cases, though the timing of visible release on the cardholder's account depends on the issuer. The acquirer sends a reversal message to the card network, which forwards it to the issuer to release the reserved funds. In practice, cardholders may see the hold persist for a short period while the reversal processes.
There is a narrow timing window for voids: once the acquirer's daily batch has closed and the transaction has entered clearing, a void is no longer possible. Merchants who need to cancel transactions should check their acquirer's batch processing schedule and submit voids before cut-off if same-day release is needed.
Voids are operationally preferable to refunds when available: a void reverses an authorisation before funds move, so there is no interchange or scheme fee assessed on the transaction. A refund processes as a separate transaction after settlement, and does not reverse the interchange and scheme fees paid on the original transaction.
Why it matters
Voids save interchange and scheme fees: a voided transaction is as if the authorisation never happened, no interchange, no scheme fees, no processing costs beyond the authorisation attempt itself. A refund after settlement cannot recover those costs.
Order management systems must trigger voids promptly: when a customer cancels an order before shipment, the payment system should automatically void the authorisation rather than letting it sit and expire. Expiring holds cause cardholder friction; explicit voids are cleaner operationally.
Void timing windows vary by acquirer and processing model: merchants with real-time processing and same-day batch cut-offs have narrower void windows than those with overnight batch processing. Merchants should understand their acquirer's processing schedule to know how much time they have to void before a capture batch closes.
Voids do not affect chargeback ratio: since no funds moved, there is no transaction to dispute. This is another reason to prefer void over refund for cancellations that happen before settlement.
With PXP
PXP supports void requests via API and dashboard for authorised but uncaptured transactions. Void eligibility is checked in real time against the transaction status. PXP surfaces authorisation timestamps and batch schedules to help merchants identify the void window for each transaction.
Frequently asked questions
What is the difference between a void and a refund?
A void cancels an authorised transaction before it has been captured and settled, no funds ever move, and the authorisation hold is released. A refund processes after a transaction has been captured and settled, returning funds that have already moved to the merchant. Voids are simpler, faster, and avoid interchange costs; refunds are the only option once settlement has occurred.
Can a void be performed after capture?
No. Once a transaction has been captured, it enters the clearing and settlement process and cannot be voided. If the merchant needs to reverse a captured transaction before settlement occurs, some acquirers support a pre-settlement reversal (sometimes called a capture reversal), but this is time-sensitive and not universally available. After settlement, only a refund can return funds to the cardholder.
Do voids affect a merchant's chargeback ratio?
No. A void occurs before any funds move, so there is no settled transaction to dispute. Chargeback ratios are calculated based on settled transactions that are disputed. Voiding cancelled transactions promptly is actually good chargeback hygiene, it prevents cardholders from seeing unexplained holds on their statements and filing disputes on transactions that were never intended to complete.
How quickly does a void release funds to the cardholder?
The speed of hold release depends on the issuer. When the acquirer sends the reversal message, the issuer should release the authorisation hold on receipt. Most issuers process reversals quickly, but the visible release on the cardholder's account, their available balance updating, may take a few hours to a business day depending on the issuer's systems and the cardholder's banking app refresh cycle.
