When a customer taps their card and sees "approved" two seconds later, a surprisingly involved sequence just happened. A credit card transaction moves through eight steps: the customer pays, the merchant submits the transaction, it routes through the payment gateway and processor to the card network, the customer's bank approves or declines it, the decision travels back to the merchant, and the funds settle later when the merchant batches out. New to terms like processor, payment gateway, or issuing bank? Read Who Are the 5 Key Players in Credit Card Processing? first — this post references all of them.
This entire sequence — all seven steps — is called authorization. The card isn't charged yet. The funds are just reserved.
Authorization and settlement are two separate things, which is why a sale can show as "approved" before the money actually moves.
This is where interchange comes in. The issuing bank transfers the sale amount minus the interchange fee to the acquiring bank, and the acquiring bank deposits what's left into the merchant's account. The whole process typically takes one to two business days.
Q: What's the difference between authorization and settlement in payment processing?
A: Authorization is the real-time approval or decline of a transaction — it happens in seconds and reserves the funds. Settlement is the actual transfer of money, which happens later when the merchant batches out for the day.
Q: Why doesn't money show up in my account right away after a sale?
A: Because approval and funding are two separate steps. A transaction can be approved instantly, but the funds aren't transferred until the merchant batches and settlement processes — usually one to two business days later.
Q: What does it mean to "batch" in payment processing?
A: Batching is when a merchant closes out all approved transactions at the end of the day and sends them for settlement. It's the step that triggers the actual movement of funds and the calculation of interchange fees.
Understanding this flow explains things that otherwise seem like mysteries: why funds arrive a day or two later, why a declined card can still show a pending charge, and where to start troubleshooting when transactions aren't behaving the way you expect.
It also matters for optimizing your processing fees. How and when a transaction settles — and what data is included — affects which interchange rate it qualifies for. A processor who manages that proactively on your behalf is worth a lot more than one who just passes through whatever rate it lands on.
