A customer in Germany pays for your SaaS plan with a card. The payment is declined, and your support inbox fills up with "your checkout is broken." Two weeks later, a different customer files a dispute and the money leaves your balance before you have even seen the evidence request. In both cases the decision was not made by you, your payment gateway, or even your processor. It was made by a bank you have never spoken to.

That bank is the issuing bank. On your side of the transaction sits the acquiring bank. Understanding the split between the two explains most of what founders find confusing about card payments: declines, fees, reserves, chargebacks, and why getting a merchant account can take weeks.

## What Is an Acquiring Bank and What Is an Issuing Bank?

An acquiring bank (also called the acquirer or merchant acquirer) is the financial institution that accepts card payments on behalf of a merchant. It holds the merchant relationship, submits transactions to the card networks, and deposits the funds into the merchant's account. If you sell something and get paid by card, an acquirer is somewhere in your chain.

An issuing bank (the issuer) is the financial institution that gives the card to the cardholder. It extends the credit line or holds the debit account, approves or declines each purchase, bills the cardholder, and handles the cardholder's disputes. The name on the front of a customer's card is usually the issuer.

Put simply: the issuer works for the buyer, and the acquirer works for the seller. The card network sits in the middle and sets the rules both of them follow.

### Acquirer vs issuer at a glance

| Dimension | Acquiring bank (acquirer) | Issuing bank (issuer) |
| --- | --- | --- |
| Who it serves | Merchants that accept cards | Cardholders who pay with cards |
| Who it bears risk for | The merchant (fraud, chargebacks, insolvency, non-delivery) | The cardholder (credit default, fraud on the account) |
| Main revenue source | Merchant discount rate or processing markup charged to the merchant | Interchange paid on every purchase, plus cardholder interest and card fees |
| Role in authorization | Routes the merchant's authorization request to the network | Makes the approve or decline decision |
| Role in disputes | Receives the chargeback, debits the merchant, relays evidence | Receives the cardholder complaint, decides whether to raise a chargeback, rules on the evidence |
| Typical institution types | Commercial banks with merchant services arms, specialist acquiring firms, licensed payment institutions | Retail banks, credit unions, consumer credit companies, fintech card programs with a sponsor bank |
| Key compliance focus | Merchant underwriting, KYC/KYB, MCC accuracy, chargeback and fraud monitoring | Cardholder KYC, credit risk, fraud scoring, consumer protection rules |

Almost every pain point maps to one column: declines come from the issuer, while reserves, rolling holds, and account terminations come from the acquirer.

## The Four-Party Model: How Issuers, Acquirers, and Networks Connect

The four-party model describes how the open card networks operate: cardholder, issuer, acquirer, and merchant, with the card network acting as the switch and rulebook between the two banks. It is called "four-party" because the network itself is treated as infrastructure rather than a party to the sale. Visa and Mastercard work this way.

In a three-party model, the network is also the issuer and the acquirer, which is why those networks can set different fees and acceptance rules.

```

Each party has a narrow job:

- **Cardholder**: holds the card and owes the issuer for purchases.
- **Issuing bank**: approves spending, pays for approved transactions, collects from the cardholder.
- **Card network**: moves messages and money between issuers and acquirers, sets interchange tables and dispute rules.
- **Acquiring bank**: takes on the merchant, guarantees the merchant to the network, and pays out funds.
- **Merchant**: sells the product and is liable for refunds and chargebacks on its sales.

In practice, gateways, processors, payment facilitators, and Merchants of Record usually sit between the merchant and the acquirer, as covered below.

## How a Card Payment Flows from Issuer to Acquirer

A single card payment moves through three stages: authorization, clearing, and settlement. Authorization happens in seconds while the customer waits. Clearing and settlement happen later, usually in batches.

### Authorization: the issuing bank decides

When the customer clicks "Pay," the checkout collects card details and sends them through a gateway to the processor, which forwards an authorization request to the acquirer. The acquirer passes it to the card network, and the network routes it to the issuing bank based on the card number.

The issuer checks available credit or balance, runs its fraud models, looks at whether 3D Secure authentication was completed, and returns an approve or decline code. If approved, the issuer places a hold on the cardholder's funds. Nothing has moved yet; the issuer has only promised to pay.

The issuer is not obliged to explain its fraud logic, so your gateway can only relay the decline code it receives. For more on that front-end leg, see how a [payment gateway works step by step](https://dodopayments.com/blogs/how-payment-gateway-works).

### Clearing: the acquirer submits the batch

Clearing is the step where the merchant, through its acquirer, submits the final transaction details to the network. For most online sales this happens automatically when the payment is captured, often at end of day in a batch.

The network matches each cleared transaction to its authorization, calculates interchange and network fees, and sends the record to the issuer, which posts it to the cardholder's statement.

### Settlement: money moves from issuer to acquirer to merchant

Settlement is when funds actually change hands. The network nets out what each issuer owes each acquirer, the issuer pays, and the acquirer receives the amount minus interchange and network fees. The acquirer then pays the merchant, minus its own markup, on its agreed payout schedule.

That payout schedule is where reserves and delays show up. A new or higher-risk merchant may see longer settlement windows or a percentage held back. If you sell through a Merchant of Record, there is one more step in this chain, explained in our guide to [MoR payouts and settlement timing](https://dodopayments.com/blogs/mor-payouts-settlement-explained).

## Who Earns What: Interchange, Network Fees, and Acquirer Markup

Every card fee a merchant pays is split three ways: interchange to the issuing bank, scheme fees to the card network, and a markup to the acquirer and any processor in between. The merchant sees one blended number; the money behind it goes to different parties.

- **Interchange** is paid by the acquirer to the issuer on each transaction. The card networks publish interchange tables, and rates vary by card type (debit, credit, premium rewards, commercial), region, whether the card was present, and the merchant category. Interchange is the issuer's compensation for carrying credit risk, funding rewards, and guaranteeing payment.
- **Scheme or network fees** are charged by the card network to both issuers and acquirers for using the network. Acquirers typically pass their share through to merchants.
- **Acquirer markup** is the acquirer's own margin for underwriting the merchant, taking on chargeback and insolvency risk, and running settlement. Processors and gateways layered on top add their own fees.

Interchange-plus pricing shows the interchange line separately; blended or flat-rate pricing bundles everything into one percentage plus a fixed fee. Cross-border and premium cards usually cost more because their interchange and network fees are higher.

## Acquiring Bank Risk: Underwriting, Reserves, MCC, and Chargeback Ratios

The acquiring bank carries the merchant's risk toward the card network. If a merchant takes payments, fails to deliver, and disappears, the cardholders still get their money back through chargebacks, and the acquirer is the one left paying. That liability explains why acquirers are cautious.

Acquirers manage that risk in four main ways:

- **Underwriting**: before boarding a merchant, the acquirer verifies the business (KYB), its owners (KYC), its website, refund policy, business model, and expected volumes. Subscription, digital goods, and cross-border businesses often get extra scrutiny because of delayed delivery and higher dispute rates.
- **Reserves**: the acquirer can hold back a portion of settlements, delay payouts, or require an up-front deposit. Reserves cover future chargebacks after the merchant has already been paid.
- **Merchant Category Code (MCC)**: every merchant is assigned an MCC that describes what it sells. The MCC affects interchange, how issuers score transactions, and which network rules apply. A wrong MCC can raise costs or breach network rules.
- **Chargeback ratio monitoring**: card networks run monitoring programs that flag merchants whose dispute or fraud ratios cross set thresholds. An acquirer with a flagged merchant faces fines and remediation demands, which it passes on, and it may terminate the account.

Merchants that fall outside an acquirer's comfort zone end up in [high-risk merchant account](https://dodopayments.com/blogs/high-risk-merchant-account) territory, with higher fees, larger reserves, and fewer options.

## The Issuing Bank's Role in Fraud and Chargebacks

The issuing bank decides whether a transaction is fraudulent at authorization, and it decides whether a chargeback is raised after the fact. The acquirer does not decide disputes. It relays them.

### Fraud decisions at authorization

Issuers score each authorization in real time using the cardholder's spending history, device and location signals, merchant category, and authentication data. Strong customer authentication through 3D Secure shifts fraud liability from the merchant to the issuer in many cases, which is why issuers tend to approve authenticated transactions more readily. This matters most for online sales, where every payment is a [card-not-present transaction](https://dodopayments.com/blogs/card-not-present-transactions) and the issuer has no chip data to rely on.

Merchants influence issuer decisions only through clean data: accurate billing descriptors, correct MCC, complete customer details, and authentication where required.

### The issuing bank's role in chargebacks

A chargeback starts when a cardholder contacts their issuer and disputes a charge. The issuer reviews the claim against the network's reason codes, and if it qualifies, the issuer raises a chargeback through the network. The issuer typically credits the cardholder provisionally while the dispute runs.

The network sends the chargeback to the acquirer, the acquirer debits the merchant and forwards the case, and the merchant can submit evidence (representment). The acquirer passes the evidence back through the network, and the issuer rules on it. If the issuer rejects the evidence, the dispute may go to pre-arbitration or arbitration under the network's rules.

The key point: the issuer is the judge, the acquirer is the courier, and the merchant is the defendant who pays the dispute fee either way. For a fuller walkthrough of reason codes and timelines, see [what a chargeback is and how it works](https://dodopayments.com/blogs/what-is-a-chargeback-explained) and our guide to [chargeback prevention for SaaS](https://dodopayments.com/blogs/chargeback-prevention-saas).

## Where Gateways, Processors, PayFacs, and Merchants of Record Fit

Payment gateways, processors, payment facilitators, and Merchants of Record all sit between the merchant and the acquiring bank. They differ in who holds the merchant account and who carries legal and compliance responsibility.

| Layer | What it does | Who is the merchant of record | Do you need your own merchant account? |
| --- | --- | --- | --- |
| Payment gateway | Captures card data securely and passes it to the processor | You | Yes, usually |
| Payment processor | Handles authorization, clearing, and settlement messaging with the acquirer | You | Yes, or via the processor's sponsored program |
| Payment facilitator (PayFac) | Holds a master merchant account with an acquirer and boards you as a sub-merchant | You (as sub-merchant) | No separate account, but you remain the seller and own tax and compliance |
| Merchant of Record (MoR) | Sells your product to the customer as the legal reseller, using its own acquiring relationships | The MoR | No |

A gateway and a processor are often sold as one product, but they do different jobs; the [payment gateway vs payment processor](https://dodopayments.com/blogs/payment-gateway-vs-payment-processor) comparison breaks that down. A PayFac speeds up onboarding by aggregating merchants under one acquirer relationship, but the sale is still yours, including sales tax, VAT, and consumer law. The difference is covered in [Merchant of Record vs PayFac](https://dodopayments.com/blogs/merchant-of-record-vs-payfac).

A Merchant of Record goes one step further. The MoR is the seller on the transaction, so the acquirer's merchant is the MoR, not you. The docs explain this distinction in the [Merchant of Record vs payment gateway overview](https://docs.dodopayments.com/features/mor-vs-pg).

## What the Acquirer vs Issuer Split Means for a SaaS or Digital Founder

For a SaaS or digital product founder, the practical question is: whose merchant account are your payments running through, and who deals with the acquirer and issuer when something goes wrong?

### The traditional setup: your own merchant acquirer relationship

With a gateway or processor, you need a merchant account with an acquirer, either directly or through a sponsored program. That means going through underwriting, being assigned an MCC, accepting whatever reserve terms the acquirer sets, and keeping your chargeback ratio below network thresholds.

You also own everything that comes with being the seller: sales tax, VAT, and GST registrations, every dispute response, and the risk that your acquirer freezes payouts if your ratio climbs. Founders who want to avoid this path can read about how to [accept credit cards without a merchant account](https://dodopayments.com/blogs/accept-credit-cards-without-merchant-account).

### The Merchant of Record setup: Dodo holds the acquiring relationships

With a Merchant of Record like Dodo Payments, Dodo is the merchant on every transaction. Dodo holds the acquiring relationships, so you do not need your own merchant account, and you do not go through acquirer underwriting for each region you sell into. Dodo accepts payments from 220+ countries and regions in 80+ currencies through its [global payments stack](https://dodopayments.com/payments).

Because Dodo is the legal seller, it calculates, collects, files, and remits sales tax, VAT, and GST, and it handles compliance. The [Merchant of Record introduction](https://docs.dodopayments.com/features/mor-introduction) in the docs covers the model in detail, and our explainer on [what a Merchant of Record is](https://dodopayments.com/blogs/what-is-a-merchant-of-record) covers it from a founder's perspective.

### Disputes under a Merchant of Record

When an issuing bank raises a chargeback on a sale made through Dodo, the dispute comes to Dodo as the merchant. Dodo manages the dispute process and passes through a $30 fee per dispute. For Visa transactions, Visa Rapid Dispute Resolution (RDR) can resolve eligible disputes before they become chargebacks, at $18 per dispute.

You can track dispute status through the dashboard and webhooks such as `dispute.opened`, `dispute.won`, and `dispute.lost`. The full lifecycle is documented in the [disputes guide](https://docs.dodopayments.com/features/transactions/disputes), and the [MoR approach to chargebacks](https://dodopayments.com/blogs/merchant-of-record-chargebacks) explains how responsibility is split.

### Bring Your Own Processor

If you already have a processor relationship you want to keep, Dodo's Bring Your Own Processor (BYOP) option lets you route payments through your own processor while still using Dodo's billing and Merchant of Record tooling, priced at 0.5%. Setup details are in the [BYOP documentation](https://docs.dodopayments.com/features/byop).

Payouts from Dodo to you follow a separate, predictable structure described in the [payout structure docs](https://docs.dodopayments.com/features/payouts/payout-structure). Payouts are free, with a $5 fee for payouts under $1,000 and standard FX on non-USD settlements.

## FAQ

### What is the difference between an acquiring bank and an issuing bank?

The acquiring bank works for the merchant: it accepts card payments, routes them to the network, and pays out the funds. The issuing bank works for the cardholder: it issues the card, approves or declines purchases, and bills the cardholder.

### Does the acquiring bank or the issuing bank decide a chargeback?

The issuing bank decides. The cardholder files the dispute with their issuer, the issuer raises the chargeback through the card network, and the acquirer passes it to the merchant and relays any evidence back for the issuer to review.

### Who receives the interchange fee in a card payment?

Interchange is paid by the acquirer to the issuing bank on each transaction, and the acquirer recovers it from the merchant. The card network sets the interchange tables, and the network charges its own separate scheme fees.

### What is the four-party model in card payments?

The four-party model describes open card networks where the cardholder, issuing bank, acquiring bank, and merchant are separate parties connected by a card network. The network routes messages and settles funds between issuers and acquirers but does not issue cards or sign merchants itself.

### Do I need a merchant account with an acquirer if I use a Merchant of Record?

No. A Merchant of Record such as Dodo Payments is the legal seller and holds the acquiring relationships, so payments run through its merchant accounts rather than yours. The MoR also handles tax, compliance, and disputes on those sales.

## Final Take

The issuing bank protects the cardholder and decides on approvals and disputes. The acquiring bank protects the network from the merchant and decides whether you can accept cards at all, and on what terms. Every decline, reserve, and chargeback you see traces back to one of those two roles.

If you would rather not hold your own acquirer relationship, manage reserves, and fight every dispute as the legal seller, a Merchant of Record takes that position for you.
