The acquirer is the bank (often working with a processor) on the merchant's side of a card transaction. It accepts the merchant as a customer, passes their card transactions into the network for authorization and clearing, and then funds the merchant's account for completed sales. The amount the merchant receives is typically the sale total minus fees, interchange, network fees, and the acquirer's own markup are usually deducted before or as the merchant is paid. The acquirer is also the party that receives a chargeback when a cardholder disputes a transaction and must work it out with the merchant.
In a flow
On the money leg, the acquirer is the destination bank that receives funds through the network's settlement and then pays the merchant. On the message leg, it submits the merchant's auth and clearing records into the network. It is the 'pay to' bank in a card flow.
Common misconceptions
Myth: The acquirer pays the merchant the full sale amount and bills fees separately later.
Reality: In a common pattern the merchant is funded net, interchange, network fees, and the acquirer's markup are taken out as part of settlement or the payout, not invoiced as a separate wire. Arrangements vary by program and contract; some merchants are on gross-plus-invoice pricing.
Myth: The acquirer and the payment processor are always the same company.
Reality: They are different roles. The acquirer is the bank of record that holds the merchant relationship and the funds; the processor is the technology moving the messages. One company can do both, but the bank role and the tech role are distinct.
