About Source

Payment settlement is the process by which funds authorized and captured through the card network are actually transferred between banks and deposited into the merchant's account. Authorization holds a cardholder's funds; settlement moves them. The two are often separated by hours to days.

Acquirers collect all captured transactions throughout the day and group them into a settlement batch. At cutoff time (often midnight local time), the acquirer submits the batch file to the card network. The batch contains all transaction details: merchant ID, authorization codes, capture amounts, and any refunds or reversals for the period.

The card network processes the batch and performs net settlement: it calculates the net position for each acquirer (total credits minus total debits including refunds and chargebacks) and instructs the issuing banks to transfer the corresponding amounts. This inter-bank transfer typically occurs through national clearing houses — Fedwire or ACH in the US, CHAPS in the UK, TARGET2 in Europe.

Once the issuing banks have transferred funds, the card network credits the acquirer's settlement account. The acquirer then calculates each merchant's net payout: gross captured amount minus interchange fees (paid to the issuing bank), minus scheme fees (paid to the card network), minus the acquirer's own processing fee. The net amount is deposited into the merchant's designated bank account, typically on a T+1 or T+2 schedule.

The merchant's billing team must then reconcile the settlement deposit against their internal transaction records — matching each payment and refund to the corresponding settlement line. Discrepancies (missing transactions, incorrect amounts, unexpected fees) must be investigated. This reconciliation process is detailed in Payment Reconciliation. Refunds that fall in a different settlement window from the original charge must be tracked separately in the reconciliation.

Frequently asked questions

Payment settlement is the process by which captured card funds are transferred between banks and deposited into the merchant's account. It begins when the acquirer batches captured transactions and submits them to the card network, which instructs issuing banks to transfer the net amounts.

The acquirer collects all captured transactions throughout the day and groups them into a settlement batch. At cutoff time the batch is submitted to the card network, which performs net settlement: calculating each acquirer's net position and instructing issuing banks to transfer funds via clearing houses (ACH, Fedwire, CHAPS, TARGET2).

Most acquirers operate on a T+1 or T+2 schedule — the merchant's bank account is credited one to two business days after the settlement batch cutoff. High-volume merchants or those with elevated chargeback risk may have longer payout schedules or rolling reserves applied.

Common issues include unexpected fee deductions not accounted for in reconciliation, refunds falling in a different settlement window than the original charge, held payouts due to elevated chargeback ratios, and FX conversion timing differences for multi-currency merchants.
