What changed on August 1
Amazon has been moving a subset of Sponsored Products, Sponsored Brands, and Sponsored Display accounts from credit card billing to proceeds deduction.
Under the old credit card model, ad costs were invoiced to your card. You had whatever credit cycle your card provided — typically 30 days after the statement close. Between the time you ran the ad spend and when cash actually left your account, most sellers had 45 to 60 days of working buffer.
Under proceeds deduction, ad costs are netted against your seller balance before Amazon disburses. There is no invoice. There is no payment date to manage. The ad spend reduces what Amazon sends you, and that happens on Amazon's disbursement timeline, not yours.
The change has been in the works since late 2025. After significant seller backlash — including a one-day ad boycott organized by the Million Dollar Sellers community — Amazon deferred the rollout from its original date to August 1, 2026.
The cash flow math
The float that credit card billing provided wasn't just a convenience. For sellers running significant ad budgets, it was real working capital.
If you spent $50,000 in Sponsored Products in July and you were on credit card billing, that $50,000 was a line item your card covered until your statement closed and payment came due. You could use your July disbursements from Amazon to finance August inventory before the ad bill arrived. The timing difference funded operations.
Under proceeds deduction, that $50,000 in July ad spend reduces what Amazon deposits. There's no timing gap. Ad spend and disbursement happen on the same schedule.
For brands running $100,000 or more per month in Amazon ads, this is a material working capital reduction. The arithmetic is not complicated — the money arrives slower and in smaller amounts, exactly when you need it for inventory purchasing.
Who this actually affects
Most Amazon advertisers are already on proceeds deduction. The change targets the subset still on credit card billing — a smaller group, but one that includes high-volume advertisers who specifically set up their accounts to preserve the float.
This is not a universal change. If you were already paying through proceeds deduction or a line of credit arrangement with Amazon, nothing changed for you on August 1. But if you were on credit card billing and you have not checked your billing settings since July, you may be on proceeds deduction now without having noticed.
Amazon's communications on this were not prominent. The seller community learned about it primarily through forums and seller groups, not a clear notification campaign.
The opt-out that exists
Amazon offers Pay by Invoice as an alternative to proceeds deduction. Under Pay by Invoice, Amazon sends an invoice at the end of each calendar month, and payment is due 30 days after that.
That structure is not the same as credit card billing, but it preserves the concept of a payment date that follows the ad spend. You know what you will owe and when. You can plan inventory financing around it. The effective float is shorter than credit card billing (30 days instead of 45-60), but it is workable for accounts that build their cash flow model around it.
According to intelliRANK and SlopePay, who both published guides on this change, the switch to Pay by Invoice happens in your Amazon Ads Console billing settings. Approval is required and is not instant — and not all account types qualify.
If you are on credit card billing and have not been moved yet, or if you want to opt out of proceeds deduction, initiating that switch before your next billing cycle matters. Once proceeds deduction is running, reversing it takes time you may not have if you are managing tight working capital into peak season.
What this means for Q4
You are entering Q4 planning with this already live. If your Amazon ad budget scales up significantly in October and November — which most e-commerce brands' do — and you are on proceeds deduction, your October and November disbursements will be smaller by the amount of that increased ad spend.
This is not a reason to cut your Amazon budget. It is a reason to model the cash flow impact now rather than discover it when your inventory financing line comes due in November.
Brands that use external financing for inventory — business lines of credit, revenue-based financing, inventory loans — need to update their Q4 cash flow projections to remove the ad float assumption. The number is gone. The budget line stays.

A billing change that reduces your disbursement before you see it is a cost increase in everything but name.
