Amazon’s New Business Cards: What Small Businesses Need to Reconcile in 2026

A business credit card can change without your bookkeeping changing with it. The result is a familiar month-end surprise: the bank statement has a new issuer, the card number in your expense feed has changed, a reward credit appears as a mysterious negative expense, and an installment purchase looks like a second bill.

Amazon’s new Prime Business Card and Amazon Business Card, issued by U.S. Bank on the Mastercard network, add useful rewards and spend controls. They also create a good reason to tighten your card-account procedures. If your business buys supplies, software, inventory, or AWS services through Amazon, the transition is not just a cardholder-service event. It is a chart-of-accounts and reconciliation event.

What changed in 2026​

The new cards launched for new applicants on May 13, 2026. There are two versions:

• The Prime Business Card is for eligible Prime members.
• The Amazon Business Card is available without a Prime membership.

Both have no annual fee and no foreign transaction fee, according to the launch announcement. Both are intended to work beyond Amazon, with Mastercard acceptance and U.S. Bank spend-management features.

The headline rewards are different:

“Amazon-covered” purchases include Amazon Business, Amazon.com, AWS, and Whole Foods Market purchases made in the United States. The rewards rules say the $150,000 limit is combined across cardmembers on the account, so issuing employee cards does not create a separate cap for every person.

The new cards also offer an alternative to rewards: eligible Amazon purchases may be split into fixed monthly payments at 0% APR for up to 12 months. The exact installment offer appears at checkout, and choosing the installment option means giving up rewards on that purchase.

That tradeoff matters. A 5% reward on a $10,000 purchase is $500, while a 12-month, interest-free payment schedule may be more valuable to a business protecting its cash reserve. The right choice depends on your cash forecast, not just the advertised percentage.

What existing cardholders should verify​

The change is not necessarily an immediate account closure for every existing customer. Amazon’s customer guidance says existing Amazon Business American Express cardholders can continue using their current cards, will receive a new card, may begin using the replacement on August 14, and will have unredeemed rewards carry over.

Treat that as a transition checklist, not a reason to stop monitoring the old account.

Confirm the replacement timeline​

Save the notices you receive from Amazon and U.S. Bank. Confirm:

1. The date the replacement card becomes usable.
2. Whether the account number, expiration date, and security code change.
3. Whether recurring charges will be transferred automatically.
4. The date the old card stops authorizing new purchases.
5. Where pending charges and refunds will appear.
6. How employee cards and virtual cards are reissued.

Do not assume that a recurring AWS subscription, advertising account, shipping service, or software renewal will update itself. Make a list of every merchant using the old card and test each one after the replacement is active.

Reconcile the overlap​

During the transition, you may have two useful data sources:

• The final statements from the old card program.
• New transaction and reward data from the U.S. Bank account.

Do not merge them by date alone. A refund posted after the replacement card arrives may relate to an old purchase. A pending Amazon order may settle days after the original authorization. Match transactions using the merchant, amount, order or invoice identifier, posting date, and card account.

Keep the old account open in your books until its balance is zero and every pending item has cleared. Then record the final payment separately and close the ledger account only after the last statement has been archived.

Build the rewards decision into your purchasing process​

Rewards are useful only when your records show what generated them and what happened when you redeemed them.

Track the cap by calendar year​

The accelerated rates are not unlimited. The program rules describe the cap as the first $150,000 of qualifying net purchases per calendar year, combined across cardmembers. A statement cycle can cross two calendar years, so a monthly report may not match the annual reward calculation.

Maintain a simple year-to-date schedule with:

• Qualifying Amazon-covered purchases.
• Qualifying top-category purchases.
• Refunds and credits.
• Purchases that used an installment offer instead of earning rewards.
• Rewards earned and redeemed.
• The remaining amount under each cap.

This schedule does not need to be elaborate. A monthly export tied to the statement and a running balance in your accounting file is enough to prevent a 5% assumption from continuing after the cap has been reached.

Review the automatically selected categories​

The new program automatically identifies the top three eligible categories outside Amazon each billing cycle. That means the reward rate may change as your spending changes. It also means you should not hard-code “2% office supplies” into a forecast without checking the card’s category-code rules.

For budgeting, use the rate shown in the current program terms and statement data. For accounting, classify the underlying purchase based on what you bought—not on the reward category assigned by the card issuer.

A $2,000 purchase of computer equipment is still equipment or a technology expense even if the card labels the merchant category as office supplies. The reward does not change the nature of the asset.

How to book purchases, rewards, and installments​

A separate card liability account makes the migration easier to audit. Create distinct accounts for the old card and the new U.S. Bank card, even if the business owner is legally liable for both.

Ordinary card purchase​

For a $1,200 order of resale inventory:

Debit   Inventory                         $1,200
Credit  Amazon/U.S. Bank card payable    $1,200

For office supplies consumed in the period, debit the appropriate expense account instead. For equipment, apply your capitalization policy and record the asset rather than treating every large purchase as supplies.

Attach the Amazon order detail or invoice to the transaction. The card statement proves payment; it may not prove what the business purchased, who used it, or whether it was inventory, an asset, or a deductible operating expense.

Statement credit or redeemed reward​

A statement credit is not a new sale. In many bookkeeping systems, a reward tied directly to a purchase is recorded as a reduction of the related cost. For example, a $60 reward applied against a supplies balance might be posted as:

Debit   Amazon/U.S. Bank card payable       $60
Credit  Office supplies expense             $60

If the underlying item is inventory, the credit may instead reduce inventory cost under the business’s accounting policy. If rewards are redeemed for a future order, record the redemption according to the platform’s order detail and preserve the reward activity report.

Tax treatment can depend on the reward terms, the business’s accounting method, and how the reward is received. The IRS has discussed credit-card rewards as rebate-like payments in a memorandum addressing an issuer’s accounting, but that memorandum is not a taxpayer-specific ruling or a substitute for professional advice. Keep the statement, reward report, and redemption record together so your tax preparer can make the correct determination.

A purchase placed on an installment plan​

Do not record the expense only when each monthly installment is paid. If the business receives the goods in June, record the purchase in June under the applicable accounting method, then track the unpaid balance as a card liability or installment sub-account.

A simple schedule should show:

• Original purchase amount.
• Purchase date and delivery date.
• Installment term.
• Monthly principal amount.
• Payments made.
• Remaining balance.
• The fact that the purchase earned no rewards.

Because the advertised installment option is 0% APR, the balance may not include interest. That does not make it free: it uses credit capacity, creates a payment obligation, and may reduce liquidity during a slow sales period.

Use the spend controls as accounting controls​

The new card program includes itemized transaction reporting with Amazon details, spending limits, approval rules, and virtual cards with restrictions and expiration dates. These features are most valuable when they become part of a repeatable control process.

Start with a short policy:

• Every employee card has one owner and one business purpose.
• Purchases above a chosen threshold require approval before checkout.
• Virtual cards are issued per vendor, project, or subscription where practical.
• Receipts and business purpose are attached within a fixed number of days.
• Personal purchases are prohibited, not “cleaned up later.”
• Monthly statements are reconciled by someone other than the person approving purchases.

Use the transaction detail to answer three questions during review:

1. Was the purchase authorized?
2. Did the business receive the item or service?
3. Is it classified correctly in the books?

This is especially important for Amazon accounts shared by multiple people. A single card account can contain inventory, office supplies, employee equipment, household items ordered by mistake, and subscriptions charged to different entities. The card feed cannot make those distinctions for you.

A 30-day transition checklist​

Use this sequence after the replacement card arrives.

Days 1–7: Map the accounts​

Export the old card’s final transactions, open the new liability account, and record the opening balance only after matching it to the issuer’s statement. List recurring merchants and employee cards that need attention.

Days 8–14: Test the feed​

Connect the new account to your bookkeeping workflow, but do not auto-post everything. Compare a sample of imported transactions with the statement and Amazon order detail. Confirm that refunds, credits, and employee-card transactions arrive with usable identifiers.

Days 15–21: Set the policy​

Choose your treatment for rewards, inventory credits, equipment purchases, and installment plans. Document who reviews spend, where receipts live, and how quickly missing documentation is escalated.

Days 22–30: Run the first full close​

Reconcile the new card to zero difference. Review the reward year-to-date schedule, the installment balances, uncategorized items, recurring subscriptions, and purchases above your approval threshold. Archive the statement and supporting exports together.

If the old account still has pending items, leave it open and repeat the reconciliation next month. Closing a ledger account before the last refund or charge settles creates an avoidable cleanup project.

The bookkeeping lesson behind the card change​

A reward rate is a purchasing incentive, not a financial-control system. The business still needs a source document for each purchase, a consistent classification policy, a separate liability account for each card program, and a monthly reconciliation that explains every difference.

Plain-text accounting can make this easier to inspect. A dated transaction file can show the original purchase, the reward credit, the account migration, and the final payment as a visible sequence rather than hiding the history inside an opaque feed. If you use a dashboard such as Fava, you can review card liabilities, spending categories, and reward-related postings without losing the underlying ledger.

Simplify Your Financial Management​

As your card program changes, clean records turn a confusing transition into a controlled month-end process. Beancount.io offers plain-text accounting that is transparent, version-controlled, and AI-ready, so you can see how purchases, rewards, and liabilities connect over time.
