What happens when your customer pays you
When a customer swipes a card, taps their phone, or sends you a check, that money does not land in your account the next morning. A chain of institutions touches it first: the customer's bank, a payment processor, a card network, and your bank. Each one takes a small cut or holds the money temporarily. Understanding this chain tells you why your deposit shows up when it does, why some payment methods cost more than others, and where to push back if something goes wrong.
The speed and cost of that journey depend on how the customer pays you. A credit card swipe involves more players and more fees than a bank transfer. A check involves your bank and the customer's bank, but no processor. An ACH transfer (direct bank-to-bank) is cheap but slow. Each method has a different fee structure, holds a different amount of fraud risk, and settles on a different timeline.
Key Takeaways
- Card payments move through a processor, a card network, and both banks before reaching your account, with each step adding a fee or delay.
- Credit card processing typically costs 2.2% to 3.5% of the transaction plus a per-transaction fee, while debit cards and ACH transfers cost less.
- Your processor holds a percentage of each transaction in a reserve account for the first 6 to 12 months, which can strain cash flow for new businesses.
- Settlement time varies by payment method: card payments usually settle in 1 to 3 business days, while ACH transfers take 3 to 5 days and checks take 5 to 10 days.
- Interchange fees (set by card networks, not your processor) are the largest cost for card payments and are the same whether you use Square, Stripe, or your bank.
The players in a card transaction and what each one takes
When a customer pays with a credit or debit card, five entities touch the money before it reaches you. The customer's bank (the issuer) approves the charge. The card network (Visa, Mastercard, Discover, or American Express) routes the transaction and sets the interchange fee. Your processor (Square, Stripe, Toast, or your bank's own system) collects the payment and deposits it to your account. Your bank (the acquirer) receives the deposit. A gateway or terminal connects the customer's card to the processor.
The interchange fee is the largest cost and goes to the customer's bank. Visa and Mastercard set these rates, which vary by card type and transaction category. A standard credit card in a retail setting typically carries an interchange fee of 1.5% to 2.2%. A rewards card costs more — often 2.2% to 2.5%. A debit card costs less, usually 0.05% to 0.25%. These rates are the same no matter which processor you use; they are not negotiable for small businesses.
Your processor's markup sits on top of the interchange fee. Processors charge either a flat percentage (often 2.9% to 3.5% total, including interchange), a per-transaction fee (usually $0.30), or both. Some processors offer tiered pricing: may have access to transactions (standard credit cards) cost less, mid-may have access to transactions (corporate or rewards cards) cost more, and non-may have access to transactions (keyed-in or phone orders) cost the most. The processor keeps this markup; it does not go to the card network or the banks.
How settlement and holds work
Your processor does not deposit the full transaction amount to your account when ready. Instead, it batches your transactions (usually daily) and sends them to your bank, which then deposits the money. This process typically takes 1 to 3 business days. During that time, the money sits with the processor or the card network, not with you. If a customer disputes the charge or the transaction fails, the processor can reverse it before the deposit clears.
Many processors also hold a reserve — a percentage of each transaction (often 5% to 10%) that sits in a separate account for 6 to 12 months. This reserve protects the processor against chargebacks and fraud. For a new business processing $10,000 per month, a 10% reserve means $1,000 is locked away each month. After 12 months, the processor releases the oldest reserves, but the newest ones are still held. This can strain cash flow, especially in the first year.
Some processors offer next-day settlement, where deposits arrive the next business day instead of 2 to 3 days. This costs more — typically an extra 0.5% to 1% of transaction volume — but can be worth it if you need cash quickly. Others offer same-day settlement for a flat fee per deposit, usually $5 to $25.
Why different payment methods cost different amounts
Debit cards cost less than credit cards because the interchange fee is lower and the fraud risk is lower. When a customer uses a debit card, the money comes directly from their account, so the issuing bank has less exposure. Visa and Mastercard debit interchange rates are typically 0.05% to 0.25%, compared to 1.5% to 2.5% for credit cards. Your processor's markup on debit is usually the same percentage, but the total cost is much lower.
ACH transfers (direct bank-to-bank payments) have no interchange fee and no card network involved. Your processor charges a flat fee per transaction, usually $0.25 to $1.00, or a percentage like 1% to 1.5%. ACH is the cheapest way to accept payment, but it is slower — typically 3 to 5 business days — and requires the customer to know your bank account number. It also carries higher fraud risk because ACH payments can be reversed up to 60 days after the transaction.
Checks have no processor fee, but your bank may charge you to deposit them, and the clearing process takes 5 to 10 business days. During that time, the check sits in your bank's processing queue. If the check bounces, your bank typically charges you a returned-check fee of $10 to $30.
Processor pricing models and how to compare them
Processors use three main pricing models: flat-rate, interchange-plus, and tiered. Flat-rate pricing (like Square's standard 2.9% + $0.30 per card transaction) is straightforward and predictable but often costs more than interchange-plus for high-volume businesses. Interchange-plus pricing (like Stripe's model) charges you the actual interchange rate set by the card network, plus the processor's markup — usually 0.5% to 1.5% plus $0.10 to $0.30 per transaction. Tiered pricing charges different rates for may have access to, mid-may have access to, and non-may have access to transactions, which can be cheaper or more expensive depending on your customer mix.
To compare processors fairly, calculate your total cost across a typical month of transactions. If you process $5,000 in standard credit cards, $1,000 in rewards cards, and $500 in debit cards, run those numbers through each processor's pricing. The cheapest option depends on your specific mix. A restaurant with mostly credit card sales might save money with interchange-plus pricing, while a retail store with a mix of cards and cash might prefer flat-rate simplicity.
Ask each processor about reserves, settlement time, and monthly fees. Some charge $10 to $30 per month just to have an account. Others waive monthly fees but charge more per transaction. Some offer volume discounts if you process above a certain threshold. These details add up over a year.
Chargebacks and fraud costs
A chargeback occurs when a customer disputes a charge with their bank instead of asking you for a refund. The bank reverses the transaction, pulls the money back from your account, and charges you a chargeback fee of $15 to $100 per dispute. If your chargeback rate exceeds 1% of your transaction volume, your processor may raise your rates, require a larger reserve, or terminate your account.
Chargebacks fall into categories: friendly fraud (the customer claims they did not recognize the charge), authorization disputes (the customer says they did not authorize the transaction), and processing errors (you charged them twice or charged the wrong amount). You can dispute a chargeback by providing evidence — a signed receipt, an email confirmation, a shipping confirmation, or a phone recording — but the process takes 30 to 60 days and you have to pay the chargeback fee regardless of the outcome.
To reduce chargebacks, use clear billing descriptors (so the charge is recognizable on the customer's statement), send order confirmations when ready, and keep records of all transactions. For online sales, use address verification (AVS) and CVV verification to catch fraudulent cards. For in-person sales, always verify the signature or ID. Some processors offer fraud detection tools that flag suspicious transactions before they settle, but these tools are not perfect and may decline legitimate sales.
How to reduce payment processing costs
The easiest way to reduce costs is to encourage customers to use cheaper payment methods. Offer a small discount for ACH or debit card payments, or charge a surcharge for credit cards (though some states and card networks restrict this). Many customers will switch if the incentive is clear.
Negotiate with your processor if you have high transaction volume. Processors often have room to lower their markup if you commit to a longer contract or agree to process a minimum monthly volume. This negotiation is most effective if you have been with the processor for at least six months and have a clean chargeback record.
Switch processors if you find a better rate. There is no penalty for leaving most processors, though some require 30 days' notice. The cost of switching is usually just the time it takes to set up a new terminal or update your payment form. If you are paying 3.5% and can move to 2.8%, that difference adds up quickly on high-volume sales.
Avoid tiered pricing if your transaction mix is mostly standard cards. Tiered pricing is designed to benefit the processor, not you. Flat-rate or interchange-plus pricing is usually more transparent and cheaper in the long run.
Frequently Asked Questions
Why does my deposit show up 3 days after I process a payment?
Your processor batches transactions daily and sends them to your bank, which then clears them. This process typically takes 1 to 3 business days. Weekends and holidays add extra days. Some processors offer next-day settlement for an extra fee, but most standard accounts settle in 2 to 3 business days.
Can I negotiate the interchange fee my processor charges?
No. Interchange fees are set by Visa, Mastercard, Discover, and American Express and are the same for all small businesses. Your processor cannot lower them. You can only negotiate your processor's markup on top of the interchange fee.
What is the reserve my processor is holding, and when do I get it back?
The reserve is a percentage of your transactions (usually 5% to 10%) that your processor holds for 6 to 12 months to protect against chargebacks and fraud. After that period, the processor releases the oldest reserves, but new reserves continue to accumulate. You get the money back as long as your chargeback rate stays low and you do not close your account.
Is it cheaper to accept ACH payments instead of cards?
Yes, ACH is typically 50% to 75% cheaper than credit card processing. But ACH is slower (3 to 5 days instead of 1 to 3 days) and requires customers to share their bank account number, which many are uncomfortable doing. ACH works best for recurring payments or invoices, not for point-of-sale sales.
What happens if a customer disputes a charge after I have already deposited the money?
Your processor reverses the transaction, pulling the money back from your account and charging you a chargeback fee of $15 to $100. You can dispute the chargeback by providing evidence, but the process takes 30 to 60 days and you pay the fee regardless of the outcome. This is why keeping detailed records of all transactions is important.
