A credit card transaction is the exchange of funds that happens when a customer pays with a credit card and a merchant receives the money for a product or service. Every credit card transaction is labelled by type, from a simple sale to a refund, chargeback, or settlement, and each type tells the payment system what the money is meant to do. For merchants, knowing how a credit card transaction works is not trivia; it protects revenue, approval rates, and cash flow. In this guide we explain the credit card transaction process step by step and break down the 10 key credit card transaction types every merchant should recognise.
The processing of a credit card payment involves labeling the payment as a specific transaction type, depending on its purpose. Merchants who accept credit card payments process different types of transactions on the daily.
What is a credit card transaction?
A credit card transaction is a request to move money from a cardholder’s bank to a merchant’s bank, authorised by the card network and the issuing bank. Think of it like a relay race: the card details are the baton, and it is passed from the shopper to the merchant, to the payment processor, to the card network, to the issuing bank, and finally back again with an approval. If any runner drops the baton, the credit card transaction fails. The type of transaction (sale, refund, chargeback, and so on) simply tells every runner what the baton is for.
The 10 credit card transaction types every merchant should know
Credit cards are one of the most widely used online payment methods globally, so merchants who accept Visa and Mastercard process several credit card transaction types every day. Here are the ten that matter most.
- Sale (aka payment or purchase)
- Pre-authorization
- Capture
- Void
- Refund
- Credit
- Adjustment
- Chargeback
- Verification
- Settlement
1. Sale (aka payment or purchase)
A sale is the standard credit card transaction: the card is authorised by the issuing bank, the merchant receives an approval code in real time, and the purchase is completed and queued for settlement. Once fully processed, the funds land in the merchant account.
2. Pre-authorization (aka authorization-only or auth-only)
A pre-authorization blocks the purchase amount on the customer’s card to be captured later. The hold usually lasts 3 to 7 days (up to 30 for some MCCs). Hotels and car rental firms rely on it for reservations.
3. Capture
A capture submits an already authorised transaction for clearing and settlement, typically once the product ships or the service is delivered.
4. Void
A void cancels an authorised but unsettled transaction. It stops funds moving and avoids interchange fees, and it never appears on the customer’s statement.
5. Refund
A refund returns a settled transaction, in full or in part, to the cardholder. It commonly follows a return or a subscription cancellation.
6. Credit
A credit returns money to a cardholder without being tied to a previous purchase, often as goodwill, a reward, or a loyalty payout.
7. Adjustment
An adjustment corrects an incorrect charge, such as a customer billed twice, keeping records accurate and customers loyal.
8. Chargeback
A chargeback is initiated by the customer through their issuing bank when they dispute a charge. Too many chargebacks mark a merchant as high risk and add fees on top of lost sales.
9. Verification
A verification checks the card number, expiry, and card security code for a card-not-present transaction, often with a €0 or €1 hold, to tokenise the card for recurring payments.
10. Settlement
Settlement is the final step: the actual transfer of funds from the cardholder’s bank to the merchant’s acquiring bank, usually processed in daily or weekly batches.
| Transaction type | Who starts it | What it does |
| Sale | Customer | Completes a purchase and moves funds to the merchant |
| Pre-authorization | Merchant | Holds funds to capture later |
| Capture | Merchant | Finalises a held amount for settlement |
| Void | Merchant | Cancels an unsettled transaction, no fees |
| Refund | Merchant | Returns a settled amount to the customer |
| Credit | Merchant | Returns money not tied to a prior purchase (goodwill or reward) |
| Adjustment | Merchant | Corrects an incorrect or duplicate charge |
| Chargeback | Customer / issuer | Forcibly reverses a disputed charge |
| Verification | Merchant | Checks card validity, often with a €0 or €1 hold, to tokenise |
| Settlement | Processor / banks | Transfers funds from issuer to acquirer |
How does a credit card transaction work?
A credit card transaction moves through five stages: authorization, authentication, clearing, funding, and settlement. In short:
- Authorization: the merchant sends the card details to the processor, which asks the issuing bank to approve the amount.
- Authentication: the issuer verifies the card and available credit (and 3-D Secure for card-not-present transactions).
- Clearing: the approved credit card transaction is routed through the card network to reconcile amounts.
- Funding and settlement: funds transfer from the issuing bank to the merchant’s acquiring bank, usually in batches.

Every credit card transaction type is a lever for merchant revenue and risk
A credit card transaction is never just a payment; it is a decision point. A sale wins revenue, a void or refund protects goodwill, a chargeback signals risk, and a settlement decides your cash flow timing.
Merchants who read each credit card transaction type correctly approve more good payments, lose fewer to disputes, and reconcile faster. Like a mechanic who knows every gear in the engine, the merchant who understands all ten types keeps the payment machine running smoothly.
Master the credit card transaction, and you master both the revenue and the risk that ride on every card your customers tap.
