Amazon Just Started Taking Ad Costs Out of Your Payouts. Check Your Billing Setting Now.

Amazon changed how a group of sellers pay for ads, and the change is about your cash, not your campaigns. As of August 1, 2026, advertisers who were still billing ad spend to a credit card are being moved to deduction from their seller account balance. That means ad costs now net against your proceeds before Amazon disburses to you. If Amazon contacted you about this and you never picked a preference, the switch already happened by default.

This is a small group. The overwhelming majority of Amazon advertisers already pay by proceeds deduction, so most sellers see nothing. But if you were one of the accounts still running ad spend on a card, this is a real working-capital event, and the notice buried it under mild language. Amazon’s own wording is that “no action required” means your default is now deduction from your balance. No action required is not the same as no impact.

What actually changed

Amazon told a small group of advertisers it was updating their available payment methods to two options: pay from your seller or vendor account balance, or Pay by Invoice. The change was first scheduled for April 15, 2026, then deferred to August 1, 2026 after seller pushback. It is now live.

Here is how the two options work. With account balance payments, Amazon handles debits and credits automatically, netting your ad cost out of your sales proceeds before it pays you. With Pay by Invoice, Amazon sends an invoice at the end of each month and payment is due 30 days later. Your credit or debit card does not disappear. It stays on file as a backup, charged only if your balance or invoice arrangement cannot cover the spend. If you did not select a preference before August 1, Amazon defaulted you to deduction from your available balance. This applies only to advertisers Amazon contacted directly, so check your account rather than assuming.

Why this hits cash flow, not ACoS

Your ACoS does not move here. Your cash timing does. Under credit-card billing you had float. You ran ad spend during the month, the charge hit your card statement, and you did not actually pay until the statement came due, often weeks later, sometimes with rewards on top. That gap was free working capital, and in a business where you are constantly funding the next inventory buy, free working capital is not a rounding error.

Proceeds deduction removes that gap. Amazon takes the ad cost out of your sales before the money reaches your bank. You are now paying for ads in near real time, out of the same disbursement you were counting on for restock, freight, and payroll. For a seller spending heavily on ads relative to margin, that pulls cash forward by weeks and shrinks every payout during high-spend periods.

The timing makes it worse. Q4 is when ad spend spikes, and it is the same window where Amazon’s peak fulfillment fees return, running October 15, 2026 through January 14, 2027. So the quarter where you most need cash to fund inventory is now the quarter where ad costs come straight off the top of your payouts and peak fees stack on your unit economics. If you model Q4 cash on last year’s card-float assumptions, you will be short.

The setting to check this week

Two moves, and they take minutes.

First, confirm which bucket you are in. Go to the Billing section of the Ads Console and look at your payment settings. If you were contacted and see your default is now deduction from account balance, you have a decision to make. If you were never contacted, you were already on proceeds deduction and there is nothing to do.

Second, if you want to protect float, select Pay by Invoice in the Ads Console billing settings. This is the closest replacement for the card cycle you lost. Amazon invoices at month end and payment is due 30 days later, which restores roughly the same delay credit-card billing gave you, without the card. Not every account qualifies for invoicing, so if the option is not available to you, plan for the tighter cycle instead of assuming you can opt back into float.

The mistake is treating “no action required” as “no decision required.” Amazon set your default to the option that is best for Amazon’s cash, which pulls the money sooner. Whether proceeds deduction or Pay by Invoice is right for you depends on your margins and how tight your restock cycle runs, but that should be your call, made on purpose, not a default you inherited because you skimmed the email.

The cross-marketplace read

Retail media platforms are steadily moving billing toward netting ad costs against your sales balance, because it lowers their credit risk and shortens their own payment cycles. Amazon is doing it here, and the same logic applies to Walmart Connect and other networks as their ad businesses mature. The operator habit worth building is simple: treat every marketplace payment-terms change as a cash-flow decision, model what it does to your disbursement timing, and pick the billing option that protects your working capital rather than the one set by default.

If you want your Amazon ad billing set up to protect cash flow going into Q4, with the right payment option chosen for your margins and your restock cycle mapped against peak fees, a strategy assessment is the fastest way to get it right before the quarter turns.
