On August 1, Amazon is changing how it collects payment for advertising. Instead of charging your credit card directly, Amazon will pull ad costs from your seller proceeds first. Your credit card stays on file as a backup, but it only gets charged if your balance runs short. That's the whole change, described as simply as possible.
The reason it caused a seller boycott in April and generated enough backlash to push the original April 15 rollout date to August isn't the mechanics. It's the downstream effects on cash flow, credit card rewards, and margin. Here's what you actually need to know.
What's Actually Changing
Right now, most sellers pay for Amazon Sponsored Products and other ad types via credit card on a standard billing cycle. You run ads, Amazon invoices you, you pay the card. Simple enough, and it gives you a few things: float (the time between when you spend and when you actually pay), rewards or cashback on that spend, and a clear separation between your ad budget and your Amazon balance.
Starting August 1, Amazon flips the order. Your ad spend gets deducted from your seller proceeds automatically. If you have $10,000 sitting in your account balance and you ran $3,000 in ads this week, Amazon takes the $3,000 before you see it. The credit card only comes into play if your balance doesn't cover the bill.
Amazon is framing this as a simplification and says it aligns a small subset of sellers with what most sellers already do. That may be true. It's also true that the sellers it affects most are the ones running significant ad spend relative to their account balance, which tends to mean the sellers who are growing fastest and investing most aggressively in the platform.
Why Sellers Are Frustrated
The cash flow issue is real. If your proceeds are being swept to cover ad costs before you can use them for inventory reorders, supplier payments, or operating expenses, your actual available cash shrinks in a way that doesn't show up neatly in your P&L. You're still profitable on paper, but the timing of when money moves matters for a business running on tight margins.
The rewards issue is also real, and it's not trivial. A seller running $50,000 a month in ad spend at 3% cashback is getting $1,500 a month back, or $18,000 a year. That's not a rounding error. It's a meaningful offset against advertising costs, and it disappears entirely under the new system if your balance covers the spend. Amazon's $2,500 promotional credit is a one-time gesture. The annual rewards hit is permanent.
The third frustration is the pattern. This change comes on top of a 3.5% fuel surcharge, extended payment reserve timelines, and a steady accumulation of fee increases over the past several years. No single change is a crisis. The combination is what's pushing sellers toward the edge of their margin tolerance.
What You Should Do Before August 1
The most important thing is to understand your current ad spend relative to your typical account balance. If your weekly ad spend is consistently less than what you have sitting in proceeds, the practical impact is limited. Amazon takes it from your balance instead of your card, and the only real difference is the lost rewards.
If your ad spend regularly exceeds or approaches your available balance, you'll want to think about this more carefully. Your credit card becomes the actual payment method in those weeks, which is functionally the same as today. But you lose the predictability of knowing your card is always the primary source, and you lose the ability to time large ad pushes around your card billing cycle.
It's worth auditing your credit card setup now. If you've been running ad costs through a card with meaningful rewards or cashback, this is the time to evaluate whether there's a card structure that still makes sense as a backup method. The cashback math changes significantly when the card is secondary rather than primary.
You should also review your inventory and cash flow cycle. If you're in a category with long supplier lead times and you rely on Amazon proceeds to fund reorders, the new timing may require you to keep more cash buffer than before. The money is still yours , it's just being applied to ad costs before it hits your disbursement.
The Bigger Picture
Amazon advertising has become a significant cost of doing business on the platform. Average cost-per-click crossed $1.05 in 2025 and is trending higher in competitive categories in 2026. The shift to deducting ad costs from proceeds rather than billing to a card is, in isolation, an operational change. In context, it's one more structural pressure on seller economics.
The brands that navigate this well are the ones that have a clear view of their unit economics at the ASIN level, know their true advertising cost of sale, and aren't running ad spend that they can't sustain from their own proceeds. If you don't have that clarity right now, August 1 is a reasonable forcing function to get it.
