How Credit Card Payments Actually Move Through Your Business
What happens when a customer swipes or taps their card at your register
When a customer pays with a credit card, their money does not go directly into your bank account. Instead, it moves through a chain of companies — the card network (Visa, Mastercard, Discover, American Express), the customer's bank, a payment processor, and your acquiring bank — before you see it. Each step takes a cut, and each step takes time. Understanding this chain is the difference between knowing why your deposit arrived two days late and being blindsided by a chargeback you did not expect.
The entire process, from swipe to your account, typically takes one to three business days. The customer's bank approves or declines the charge in seconds. The payment processor collects the transaction data and batches it with other sales from your business. Your acquiring bank then settles the batch — that is, actually moves the money — into your account. During this window, the funds are in transit, and you cannot spend them yet.
Key Takeaways
- Credit card payments pass through at least four separate companies before reaching your bank, and each one charges a fee that reduces what you deposit.
- Settlement — the moment money actually lands in your account — usually happens one to three business days after the transaction, not immediately.
- Chargebacks occur when a customer disputes a charge with their bank instead of asking you for a refund, and they cost you the sale amount plus a fee.
- Your payment processor and acquiring bank are different entities; the processor handles the transaction, and the acquiring bank handles the deposit.
- Interchange fees, assessment fees, and processing fees are the three main costs you pay, and they vary by card type, transaction size, and your business category.
The companies involved and what each one does
Your payment processor is the company you contract with directly — Square, Stripe, PayPal, Toast, or your bank's own processing arm. They provide the equipment (card reader, point-of-sale terminal) or software (online checkout), and they handle the technical side of capturing the card data and sending it through the network. They also collect fees from you and pass some of them along to the other players in the chain.
Your acquiring bank is the financial institution that actually deposits money into your business account. You may not know their name because your processor often handles the relationship on your behalf. The acquiring bank buys the transaction from the processor, holds the funds briefly, and then deposits them to you. They charge the processor an interchange fee, which the processor passes to you.
The card networks — Visa, Mastercard, Discover, American Express — set the rules for how transactions move through the system and set the interchange rates that acquiring banks must pay. They do not touch your money directly, but they control the fees. American Express is different: they are both the network and the acquiring bank, so they take a larger cut but fewer companies are involved.
The customer's bank (the issuing bank) approves or declines the charge and later sends the money to the acquiring bank. They also handle disputes if the customer claims the charge was fraudulent or unauthorized.
How fees work and why they vary
You pay three main categories of fees: interchange, assessment, and processing. Interchange is the largest and goes to the card networks and the customer's bank. Assessment fees go to the networks themselves. Processing fees go to your processor for providing the service.
Interchange rates are not flat. They depend on the type of card (a rewards card costs more than a basic card), the type of transaction (a card-present transaction at a physical location costs less than a card-not-present transaction online), and your business category. A restaurant pays different rates than a retail store, which pays different rates than a nonprofit. Visa and Mastercard publish their interchange schedules publicly, but they are complex and change several times a year.
Processing fees are what your processor charges you. Some charge a flat percentage of each transaction (typically 2 to 3 percent for card-present, 2.5 to 3.5 percent for online). Others charge a flat fee per transaction plus a percentage. Some charge a monthly subscription plus lower per-transaction fees. The structure you choose affects your total cost depending on your sales volume and average transaction size.
Assessment fees are smaller — usually under 0.1 percent — and go to the card networks. Your processor includes these in their fee structure, so you do not pay them separately, but they are part of what you owe.
Settlement: when money actually reaches your account
Settlement is not the same as authorization. When a customer's card is approved at the moment of sale, that is authorization — the customer's bank has said yes, the funds are there. Settlement is when the money actually moves from the customer's bank to your acquiring bank to your business account.
Your processor batches transactions throughout the day. At the end of the day (or at a time you set), the batch is submitted for settlement. The acquiring bank then processes the batch, deducts fees, and deposits the net amount into your account. This usually takes one to three business days, though some processors offer next-day settlement for an additional fee.
Weekends and holidays extend the timeline. A transaction authorized on Friday may not settle until Tuesday. A transaction authorized on December 23 may not settle until after the new year. During high-volume periods like the holidays, some acquiring banks slow down settlement to manage risk.
You can see authorized transactions in your processor's dashboard before they settle, but you cannot spend the money until it lands in your bank account. Some processors offer early access to funds (same-day or next-day) for a higher fee, which can help if you need cash flow, but it costs more.
Chargebacks: what they are and how they hurt
A chargeback occurs when a customer disputes a charge with their bank instead of asking you for a refund. The customer tells their bank the charge was unauthorized, fraudulent, or not as described. The bank then reverses the charge, pulls the money back out of your account, and charges you a chargeback fee (typically $15 to $100 depending on your processor and the card network).
You lose the sale amount plus the fee. If the customer was right — they did not authorize the charge or it was fraudulent — you have little recourse. If the customer was wrong or lying, you can dispute the chargeback by providing evidence: a signed receipt, an email confirmation, a tracking number showing delivery, or a video of the transaction. The burden is on you to prove the charge was legitimate.
A high chargeback rate (usually defined as over 1 percent of your transactions) can result in your processor terminating your account or raising your fees. Some processors require you to implement fraud prevention tools if your chargeback rate climbs. Card-not-present transactions (online or phone orders) have higher chargeback rates than card-present transactions, which is why online fees are higher.
Reconciliation: matching what you sold to what you received
Reconciliation is the process of comparing your point-of-sale records to your bank deposits. You should do this daily or at least weekly. Log into your processor's dashboard and your bank account and check that the number of transactions and the total dollar amount match (minus fees).
Discrepancies happen. A transaction may fail to settle. A customer may dispute a charge after it has already been deposited. A refund you issued may not have processed yet. A fee may have been added that you did not expect. By reconciling regularly, you catch these issues early instead of discovering them weeks later when the money is already gone.
Keep records of all transactions, refunds, and chargebacks for at least one year. If a customer claims they were charged twice or a chargeback dispute lands on your desk, you will need proof of what actually happened. Your processor stores this data, but your own records are your backup.
Choosing a processor and what to compare
When comparing processors, look at the total cost, not just the per-transaction rate. A processor charging 2.5 percent on every transaction may cost you less than one charging 2 percent plus a $30 monthly fee, depending on your volume. Calculate your expected monthly sales, multiply by the rate, add any monthly fees, and compare the total across three to five processors.
Ask about settlement speed. Some offer next-day settlement at no extra cost. Others charge for it. If you need cash flow, the cost of faster settlement may be worth it. Ask about chargeback fees and what happens if your chargeback rate rises. Ask whether they support the payment methods you need — online, in-person, invoicing, recurring billing.
Ask about the contract. Some processors lock you in for a year or longer. Others month-to-month. If you are locked in and want to leave, you may owe an early termination fee. Read the fine print about what happens if you close your account — some processors hold your final deposit for 30 to 90 days.
Check whether the processor offers tools to reduce chargebacks, such as address verification (AVS) for online transactions or fraud detection software. These tools cost extra but can save you money if they prevent chargebacks.
Frequently Asked Questions
Why does my deposit show up as less than what I sold?
Fees are deducted from your deposit. If you sold $1,000 and your average fee is 2.9 percent, your deposit will be approximately $971. The $29 difference is split among interchange, assessment, and processing fees. Your processor's dashboard should show a detailed breakdown of which fees were deducted.
Can I pass the credit card fee on to my customers?
Yes, but with restrictions. Visa and Mastercard allow you to add a surcharge for credit card payments, but the surcharge cannot exceed your actual cost (usually around 3 to 4 percent). American Express does not allow surcharges. You must disclose the surcharge before the customer completes the purchase. Some states and cities have additional rules, so check your local laws.
What is the difference between a processor and an acquiring bank?
Your processor is the company you sign a contract with and use every day. Your acquiring bank is the financial institution that actually deposits money into your account. Your processor may be owned by or partnered with your acquiring bank, or they may be separate companies. Either way, you contract with the processor, and they handle the relationship with the acquiring bank.
How long do I have to refund a customer?
Card networks require refunds to be processed within 60 to 120 days of the original transaction, depending on the card type. However, it is best practice to refund within 5 to 10 business days. The refund will appear as a credit on the customer's statement, but it may take one to three business days to show up, just like a regular deposit.
What should I do if a customer claims they were charged twice?
First, check your processor's dashboard to see if there are actually two transactions or if it is a display error. If there are two, issue a refund for one immediately. Document the refund in your records. If the customer disputes the charge with their bank anyway, you will have proof that you refunded it, which helps you win the chargeback dispute.
