An acquiring bank is the bank that holds your merchant account and receives card payments on your behalf. It is your side of the transaction, opposite the issuing bank that gave your customer their card. It also carries the financial risk if your business takes money and fails to deliver.
The two banks in every transaction
| Acquiring bank | Issuing bank | |
|---|---|---|
| Whose side | Yours, the merchant | Your customer's |
| Holds | Your merchant account | The customer's card account |
| Decides | Whether to accept you as a merchant | Whether to approve each charge |
| Receives | The transaction funds | Interchange |
| Risk carried | You fail to deliver | The customer fails to pay |
Interchange is the payment that flows from the acquirer to the issuer to compensate it for the credit risk and fraud liability it carries — see what is interchange.
Why the acquirer underwrites you
This is the part that surprises people. If a customer pays for something and never receives it, they charge back. If your business no longer has the money — or no longer exists — the acquiring bank funds that refund out of its own pocket.
That single fact explains almost everything about merchant onboarding.
- Underwriting exists to assess how likely you are to fail to deliver.
- Reserves exist to hold a buffer against that outcome.
- Prohibited categories are the ones with historically high non-delivery or dispute rates.
- Long fulfilment windows — pre-orders, events months away, annual contracts — attract more scrutiny, because the gap between payment and delivery is when the risk sits.
Does it matter who yours is?
For most businesses, no. It becomes relevant at scale, where acquiring relationships affect authorisation rates in particular regions, and where a dedicated merchant account with a chosen acquirer can be worth the underwriting for better pricing.
GOOD QUESTIONS
Frequently asked
What is the difference between an acquirer and an issuer?+
The acquirer is your bank in the transaction — it holds your merchant account and receives the funds. The issuer is your customer's bank, which issued their card and decides whether to approve the charge. Interchange flows from the acquirer to the issuer.
Is my payment processor the acquiring bank?+
Usually not, though some large providers are both. Most processors partner with an acquiring bank behind the scenes; you never interact with it directly. Adyen and a handful of others hold their own acquiring licences.
Why does the acquiring bank care about my business model?+
Because it is financially liable if you take payment and fail to deliver. If your company disappears with prepaid orders outstanding, the acquirer funds the refunds. That liability is what underwriting, reserves and prohibited-category lists exist to manage.
Can I choose my acquiring bank?+
Only with a dedicated merchant account. With an aggregator like Stripe or Paydude, the provider's acquiring relationships are part of the product and are not selectable.
