November and December are the busiest months of the year for a lot of small businesses. They're also the months when a processing problem costs the most: a frozen deposit, a declined terminal on a Saturday, or a run of chargebacks that arrives in January after the money is spent.
The season is big and still growing. The National Retail Federation reported that U.S. holiday sales from November 1 through December 31, 2025 grew 4.1% over 2024, based on card purchase data. NRF had forecast that spending would pass $1 trillion for the first time. More sales is good news. It also means more transactions, more card types and more risk going through an account that was set up for an ordinary month.
Here's what to check before November 1, while there's still time to fix it.
1. Know Why Q4 Changes Your Costs
Your effective rate (total fees divided by total card volume) usually moves in the holiday months, even if your pricing hasn't changed. Three things push it:
- More keyed and online orders. Phone, online and keyed-in sales are "card not present" transactions, and card networks generally charge higher interchange on them than on chip or tap payments in person.
- More rewards and premium cards. Gift buyers reach for the cards that earn points, and those cards usually carry higher interchange than basic debit or standard credit cards.
- More disputes. More orders, more shipping and more first-time customers mean more chargebacks, and each one carries a fee on top of the lost sale.
None of that is a reason to panic. It's a reason to know your baseline. Pull a statement from a normal month now, work out your effective rate, and you'll be able to tell in January whether the season cost what it should have, or whether something else changed. If your rate has already been creeping up, read why your processing rates went up first.
2. Check Your Account Settings Before November
Most of these take a phone call or a few minutes in your processor's online portal:
- Deposit timing: how many business days from batch to bank, and whether weekend and holiday batches are held. Plan your cash for the bank holidays on Thanksgiving, Christmas and New Year's Day.
- Batch settings: whether your terminal closes the batch automatically each day. A batch left open over a busy weekend can settle late or, on some systems, at a higher rate.
- Volume limits: the monthly volume and largest single ticket your account was approved for. They're often in the approval letter or the merchant portal.
- Reserve terms: whether your agreement lets the processor hold back part of your deposits, and what triggers it.
3. Raise Your Processing Limit Before You Need It
Processors approve each account for an expected monthly volume and average ticket. A sudden jump above those numbers looks a lot like fraud to a risk team, even when it's just a good December. The usual response is a hold on deposits while they review the account, at exactly the moment you need the cash for payroll and restocking.
If you expect your holiday volume to run well above a normal month, call your processor in October, give them your forecast and last year's numbers, and ask for the limit to be raised in writing. It's a short conversation now and a long one in December.
4. Fraud Basics for Peak Season
Card-not-present fraud rises with online and phone volume. A few habits catch most of it:
- Turn on address and security-code checks (AVS and CVV) for online and keyed orders, and decide in advance what you'll do with a mismatch.
- Avoid keying in cards that are present. Dip or tap whenever the card is in front of you. Keying in a card that's present costs more and gives you weaker protection in a dispute.
- Be careful with rush orders shipped to a different address, especially large first-time orders for resellable goods.
- Make your descriptor recognisable. The business name on your customer's statement should be one they recognise. "I don't recognise this charge" is one of the most avoidable disputes there is.
The card networks watch this too. Visa's monitoring program combines fraud reports and disputes on card-not-present sales into a single ratio, and in the U.S. it lowered the level at which a merchant is flagged as "Excessive" from 2.2% to 1.5% on April 1, 2026. Visa's program applies only once a merchant reaches 1,500 fraud reports and disputes in a month, so most small businesses will never meet it directly. Your processor watches the same numbers for your account, though, and can act well before you reach Visa's line.
5. Have a Backup Plan for the Terminal
- Update and test terminals in October, not the week before Black Friday.
- Know whether your system has an offline mode, what it accepts while offline, and the risk you carry for offline approvals that later decline.
- Keep a second way to take cards: a spare terminal or a phone reader on the same account.
- Brief seasonal staff on refunds, voids and what to say when a card is declined.
6. Read Your Statements as the Season Goes
Don't wait for January. Look at the November statement as soon as it arrives: total fees, effective rate, chargebacks, and any new line items. Holiday months are when fees nobody mentioned tend to show up, and they're easier to dispute while they're fresh. Our list of hidden fees on a processing bill shows what to look for.
