Acquirer

What is an acquirer?

An acquirer (or acquiring bank) is the bank or financial institution licensed by the card schemes — Visa, Mastercard, and others — to process card payments on behalf of a merchant and settle the funds into the merchant’s account. During a payment, the acquirer forwards the authorization request through the card network to the cardholder’s issuing bank and then handles clearing, settlement, and payout to you as the merchant.

Why does an acquirer matter?

The acquirer is the link that actually moves money from the customer’s card to your bank account, and it carries the financial risk if a merchant cannot cover its chargebacks or fraud losses. An acquirer is not the same as a payment gateway or a PSP: the gateway transmits transaction data, while the acquirer owns the merchant relationship and settles the amount. The acquirer’s fees — interchange, card scheme fees, and the acquirer’s own markup — make up a large share of what each order costs you.

Common use cases

• Choosing a payment provider and needing to understand who actually acts as the acquirer behind it.
• Seeing many declined payments and needing to tell whether the decline comes from the acquirer or the issuing bank.
• Negotiating fees and wanting to know what is interchange and what is the acquirer’s markup.
• Handling chargebacks and needing to know the acquirer’s deadlines and documentation requirements.
• Selling into new markets where local cards require an acquirer with the right coverage.

Shopify perspective

If you use Shopify Payments, the solution is powered by Stripe, which handles the underlying acquiring relationship for you — so you do not need to set up a separate account with an acquirer yourself. If you choose a third-party gateway instead, you typically sign a separate agreement with an acquirer and manage the fees, payout schedules, and decline codes on your own. Always test real orders and read the decline messages in your Shopify admin so you can tell whether an issue comes from the acquirer or the customer’s bank.
