An acquirer, or acquiring bank, is a financial institution that enables merchants to accept card payments. It works on the merchant side of a transaction, sends authorisation requests through card networks, receives the issuer's response, and helps settle approved payments into the merchant's account. An acquirer, or acquiring bank, is a financial institution that enables merchants to accept card payments. It works on the merchant side of a transaction, sends authorisation requests through card networks, receives the issuer's response, and helps settle approved payments into the merchant's account.
In a card transaction, the acquirer connects the merchant to the card network and the customer's issuing bank. The issuer decides whether to approve or decline the transaction, while the acquirer delivers that response back to the merchant and supports settlement if the payment is approved.
The main acquirer's tasks are:
If a payment is authorised and later settled, the acquirer helps transfer the funds to the merchant, minus applicable fees, reserves, or adjustments. If the merchant issues a refund, the acquirer routes the refund request back through the card network to the issuer so the funds can be returned to the cardholder. Since the acquirer evaluates the risk for each transaction, the fees may vary depending on the services provided.
Local acquiring means processing card payments through an acquirer located in the same country or region as the customer or transaction. Instead of routing a payment through a foreign acquirer, the merchant uses a local acquiring partner that is connected to the domestic market, local card schemes, currencies, and regulatory requirements.
For merchants, local acquiring can help improve approval rates, reduce cross-border fees, support local currencies, and make settlement more predictable. It is especially important for businesses expanding into new markets, where customers, issuers, and payment networks may respond better to locally processed transactions.
However, local acquiring also adds operational complexity. Merchants may need to manage several acquirers, contracts, integrations, settlement flows, and reporting formats across markets.
Acquirers affect payment performance, costs, settlement timelines, chargeback handling, and market coverage. The right acquiring setup can help merchants improve approval rates, support more regions, reduce processing risk, and manage transaction costs.
Many growing merchants work with multiple acquirers or PSPs to avoid relying on a single provider. This can improve redundancy and give payment teams more flexibility in routing transactions across markets, currencies, and risk profiles.
The acquirer and issuer are two different parties in a card transaction.
The acquirer works on the merchant side. It enables the merchant to accept card payments, sends transaction requests to card networks, receives authorisation responses, and supports settlement.
The issuer works on the cardholder side. It provides the customer’s payment card, manages the cardholder’s account, and decides whether to approve or decline the transaction.
In simple terms, the acquirer represents the merchant, while the issuer represents the cardholder.
A merchant can work with an acquirer directly or through a payment service provider, payment facilitator, ISO/MSP, or payment aggregator. The right setup depends on the merchant's business model, transaction volume, risk level, technical needs, and target markets.
When a merchant applies for a direct acquiring relationship, the acquirer reviews the business before opening a merchant account. This underwriting process may include checks of the merchant's industry, business history, processing volume, chargeback risk, financial position, website, ownership structure, and compliance profile.
If approved, the merchant gains the ability to accept card payments under the acquirer's conditions and the card network's rules. The acquirer may also define pricing, settlement terms, rolling reserves, transaction limits, and risk controls.
Direct acquiring can give merchants more control, but it usually requires more paperwork, technical setup, and compliance checks. Smaller merchants or companies that need faster onboarding may choose to work through a PSP, PayFac, aggregator, or ISO/MSP instead.
As you can see, opening a merchant account with an acquiring bank involves extensive paperwork and audits. However, the payment industry is evolving and offers merchants many other options for obtaining a merchant account. Merchants do not always need a direct acquiring relationship. They may accept payments through a PSP, PayFac, ISO/MSP, or payment aggregator. These providers can simplify onboarding, provide technical infrastructure, and connect merchants to acquiring services, but the level of control, pricing transparency, settlement flexibility, and risk responsibility may differ.
Corefy helps businesses connect and manage multiple acquirers, PSPs, and payment providers through one payment infrastructure layer. This gives payment teams more flexibility to route transactions, manage provider coverage, monitor performance, and support payment operations across different markets.
