What happens when you click "pay now" on an ecommerce site

When you enter your card details and submit an order, your payment does not go straight to the merchant's bank account. Instead, it travels through at least four separate institutions in a chain that usually takes one to three business days to complete. Your card issuer (your bank) talks to a payment processor, which talks to the merchant's bank, which talks to the merchant. Each step has a specific job: authorizing the charge, moving the money, and settling the accounts.

The process splits into two phases. Authorization happens in seconds—your bank confirms you have enough funds and the card is valid, and the merchant gets a yes or no. Settlement happens later, usually overnight or the next business day, when the actual money moves from your account to the merchant's account. You see the charge on your statement right away because authorization freezes the funds, but the merchant does not receive the money until settlement completes.

Key Takeaways

  • Authorization (the when ready yes or no when you pay) and settlement (when money actually moves) are two separate events that happen hours or days apart.
  • Your payment travels through your bank, a payment processor, the merchant's bank, and the merchant in that order—not directly from your account to theirs.
  • Interchange fees (paid by the merchant to your bank) and processing fees (paid by the merchant to the processor) are built into the merchant's costs, not added to your price at checkout.
  • If a merchant never settles your payment, the authorization hold drops after three to seven days and the charge disappears from your account.

The four institutions involved and what each one does

Your card issuer is your bank or credit union—the institution that issued your card and holds your account. When you submit payment, they receive a request to authorize the charge. They check whether the card is active, whether you have sufficient funds or credit, and whether the transaction looks fraudulent. They send back an approval code (or a decline) in seconds. They do not move any money at this point; they only reserve the funds so you cannot spend them twice.

The payment processor is the company that handles the technical connection between the merchant's website and the banking system. Common processors include Stripe, Square, PayPal, and Authorize.Net. The processor receives your card details from the merchant's checkout page, encrypts them, sends the authorization request to your bank, receives the response, and reports back to the merchant. The processor also handles disputes, refunds, and the overnight settlement batch that actually moves money.

The merchant's bank (also called the acquiring bank) holds the merchant's business account. During authorization, they receive notice that a charge is coming. During settlement, they receive the actual funds from your bank and deposit them into the merchant's account, minus the fees the merchant owes. The merchant's bank also handles chargebacks if you dispute the charge later.

The merchant is the business selling you the product. They own the website, set the price, and receive the money at the end of the process. They pay fees to the processor and to their bank for the privilege of accepting cards, and they bear the risk if you dispute the charge or if the payment fails.

Why authorization and settlement are not the same thing

Authorization is a promise, not a transfer. When your bank approves the charge, they are saying "this person has the money and this card is valid." Your bank then holds that amount in a separate reserve so you cannot spend it elsewhere. You see the charge appear on your account when ready because the funds are frozen, but they are still in your account—your bank has not sent them anywhere.

Settlement is the actual movement of money. The next morning (or sometimes the same evening), the processor bundles all the day's approved transactions and sends them to the banking system in a batch. Your bank pulls the held funds from your account and sends them to the merchant's bank. The merchant's bank deposits the money into the merchant's account. This entire process usually takes one business day, though some processors settle twice daily and others settle once per day.

If a merchant never submits a transaction for settlement—for example, if their system crashes or they go out of business—the authorization hold expires. Your bank typically releases the hold after three to seven days, and the charge disappears from your account as if it never happened. You are not charged anything because no money actually moved.

Fees and who pays them

Three fees are involved in every card transaction, and the merchant pays all of them. You do not see these fees at checkout because they are built into the merchant's costs and pricing.

Interchange fees go to your card issuer (your bank). These fees are set by Visa, Mastercard, or American Express and vary by card type and transaction category. A typical interchange fee is 1.5 to 2.5 percent of the transaction amount, though some cards (like business or rewards cards) carry higher rates. The merchant's bank collects this fee during settlement and passes it to your bank.

Assessment fees go to the card network (Visa, Mastercard, etc.) and are usually 0.1 to 0.15 percent of the transaction amount. These are smaller and less visible than interchange fees.

Processing fees go to the payment processor and vary widely depending on the processor and the merchant's contract. A small business using Stripe might pay 2.9 percent plus 30 cents per transaction. A large retailer with a custom contract might pay 1.5 percent. The processor keeps some of this fee and passes the rest to the merchant's bank.

The merchant absorbs all these costs. Some merchants build them into their prices; others offer discounts for cash or lower prices in-store than online. You are never charged these fees directly.

What happens if something goes wrong during payment

If your card is declined during authorization, the merchant's system tells you when ready and the transaction stops. No money is held, no settlement occurs. Common reasons for decline include insufficient funds, a card reported stolen, a mismatched address or CVV, or fraud detection flagging the transaction as suspicious.

If authorization succeeds but settlement fails—for example, because your bank discovers fraud after the fact or because the merchant's bank has a system outage—the merchant does not receive the money. Your bank releases the authorization hold after a few days, and the charge disappears from your account. The merchant sees the failed settlement in their processor's dashboard and may contact you to ask you to pay again.

If you dispute a charge after settlement is complete, your bank initiates a chargeback. Your bank pulls the money back out of the merchant's account and returns it to you while they investigate. The merchant has the right to dispute the chargeback by providing evidence (like a shipping confirmation or your IP address matching your home location). If the merchant wins, the money goes back to their account. If you win, you keep the money and the merchant loses it.

How timing works for different payment methods

Credit and debit cards follow the authorization-then-settlement model described above. Bank transfers (ACH in the United States) work differently: the merchant submits your bank account number and routing number, your bank processes the transfer, and the money moves directly from your account to the merchant's account over one to three business days. There is no authorization phase; the transfer either succeeds or fails after it is submitted.

Digital wallets like Apple Pay and Google Pay use your card details behind the scenes, so they follow the same authorization-and-settlement timeline as a regular card payment. PayPal and similar services hold the money in their own account first, then transfer it to the merchant's bank account, which adds an extra day or two.

Buy now, pay later services (like Affirm or Klarna) pay the merchant when ready in full, then collect from you in installments. From the merchant's perspective, they receive their money the same day. From your perspective, you are making multiple smaller payments over weeks or months.

Why some online purchases take longer to show up than others

The authorization-to-settlement timeline is usually one to three business days, but some merchants settle faster or slower depending on their processor and their contract. A large retailer with a custom agreement might settle the same day. A small business using a standard processor might settle the next day. Some processors allow merchants to choose between daily settlement and twice-daily settlement.

Certain categories of merchants settle more slowly by default. Hotels, car rental companies, and gas stations often hold authorization for longer because the final charge amount is not known at the time of purchase (the tip amount at a restaurant, the final mileage at a rental company). These merchants may not submit the transaction for settlement until days after you pay.

International transactions add extra time because they travel through currency conversion systems and international banking networks. A purchase from a merchant in another country may take five to seven business days to settle, even if the authorization happens when ready.

Frequently Asked Questions

Why does my bank show the charge when ready if the merchant does not get the money for a day?

Your bank shows the charge right away because the authorization freezes the funds in your account. The money is reserved and unavailable to you, so your bank displays it as a pending charge. The merchant does not receive the money until settlement, which happens later. Once settlement completes, the charge moves from pending to posted on your statement.

Can a merchant charge me twice if something goes wrong?

It is possible but rare. If your authorization succeeds but settlement fails, and the merchant does not realize it, they might ask you to pay again. If you do, you could end up with two charges. Check your statement after a few days; if you see two identical charges, contact your bank to dispute one of them. Your bank can reverse the duplicate charge.

What is the difference between a pending charge and a posted charge?

A pending charge is an authorization hold—the merchant has received approval and your bank has reserved the funds, but settlement has not happened yet. A posted charge means settlement is complete and the money has moved from your account to the merchant's account. Pending charges usually become posted within one to three business days.

Do I have to wait for settlement before I can return something?

No. You can request a return or refund at any point. If you request a refund before settlement, the merchant can cancel the transaction and the authorization hold drops. If you request a refund after settlement, the merchant submits a refund request to their processor, which reverses the transaction and sends the money back to your account. Refunds usually appear in your account within one to three business days.

Why do some websites ask for my billing address and CVV if they already have my card number?

Your billing address and CVV are security checks that your bank uses during authorization to verify you actually own the card. A fraudster might have your card number but not your address or the three-digit code on the back. Merchants that collect this information have lower fraud rates and may may have access to for lower processing fees.
