A payment rule that triggered a rare seller boycott in the spring finally took effect on August 1. Here is what changed, why it hurts, and what brands can do to protect their margins heading into the fourth quarter.
For a certain group of United States Amazon sellers, the way they pay for advertising changed for good this past weekend. As of August 1, those advertisers can no longer set a credit card as the default method for their Sponsored ad spend. Instead, Amazon now takes those advertising costs straight out of their sales proceeds before the money ever reaches their bank account. The shift is small in the way Amazon describes it and large in the way many sellers feel it, and it arrived only after one of the most public seller revolts the marketplace has seen in years.
What actually changed
The mechanics are straightforward. Amazon is moving a subset of advertisers off credit card billing and onto what it calls proceeds deduction. Under the new setup, the cost of running Sponsored Products, Sponsored Brands, and Sponsored Display campaigns is netted against a seller’s account balance first, and only what remains is paid out. A credit card can still sit on file, but it now works only as a backup for when proceeds are not enough to cover the spend. Sellers who did not actively choose a billing preference before August 1 were moved to proceeds deduction automatically.
There is an alternative, and it has been quietly overshadowed in the noise. Affected sellers can switch to Pay by Invoice inside their advertising billing settings. With that option, Amazon sends an invoice at the end of each month and gives the seller 30 days to pay it. That preserves a version of the breathing room, the float, that the old credit card system used to provide, which is why many agencies have spent the summer urging clients to opt in rather than let the automatic migration decide for them.
It is worth being clear about what this is and is not. Amazon is not charging more for advertising. Ad rates, campaign performance, and organic ranking are all untouched. What changes is timing, specifically when money leaves a seller’s account, and for businesses that had been leaning on credit cards to manage that timing, the difference is real. Sellers also lose the rewards they used to earn on that spend, roughly 2 to 2.5%, which at scale can add up to tens of thousands of dollars a year.
The revolt that forced a delay
None of this landed quietly the first time around. The change was originally scheduled for April 15. When notices began appearing in Seller Central inboxes with no public announcement, word spread fast through seller forums and agency alerts, and the reaction was sharp. In mid April, more than a hundred seven figure sellers went dark on their advertising for a full day in a coordinated boycott organized through the community Million Dollar Sellers. An internal poll of that group found that 80% of members believed the policy would wipe out a quarter or more of their available cash.
The language from sellers was blunt. Adam Runquist, founder of the brand acquirer Heist Labs, wrote that combined with the payout delays the change would create a major cash flow crunch. Others noted that the last convenient credit card option in their business had simply vanished, taking the rewards and the timing cushion with it. Amazon responded by pushing the date back to August 1, saying the delay would give the affected group more time to prepare, and it offered a one time promotional credit of $2,500 to soften the transition. It also clarified that the policy touched only a small share of advertisers, not the entire base.
The bigger picture is a triple squeeze
The reason this particular change hit a nerve is that it did not arrive alone. It is the third in a series of moves that together tightened the screws on seller working capital in a matter of months. The first came in the spring, when Amazon changed how it times seller payouts. Under the new rule, often shortened to DD+7, Amazon holds a seller’s proceeds until seven days after an order is delivered, rather than seven days after it ships. That sounds minor until you run the math. For a seller doing $10,000 a day in sales, the delay can leave roughly $70,000 sitting inside Amazon’s disbursement pipeline at any given moment.
The second move was a cost, not a timing change. In April, Amazon added a temporary fuel and logistics surcharge of 3.5% to fulfillment fees across Fulfillment by Amazon in the United States and Canada. The company tied it to a sharp rise in fuel prices, with diesel climbing close to 18% in the first months of the year amid conflict in the Middle East and tighter oil supply. For a seller moving 10,000 units a month, that surcharge alone can mean around $1,700 in extra cost every month, or north of $20,000 over a year. Sellers were quick to point out that surcharges labeled temporary have a long history of becoming permanent.
Stack the payout delay, the surcharge, and now the advertising billing change on top of one another, and you get what several observers have called a triple squeeze on cash flow. It is a squeeze arriving at a moment when margins were already thin. Marketplace Pulse has estimated that Amazon’s various fees now consume somewhere between 45% and 55% of revenue for many brands once advertising, fulfillment, and operational costs are added together. Given that third party sellers account for more than 60% of everything sold on Amazon, this is not a niche problem.
Why the timing matters more than the money
The danger with a liquidity crunch is that it rarely stays contained to a spreadsheet. When cash gets tight, operational decisions start to slip. A seller might delay a restock, pause a shipment, or pull back on advertising to conserve funds. Each of those moves can trigger a chain reaction, from a lost Buy Box to slower deliveries to rising cancellations. Amazon’s own systems can read those signals as operational risk, which can invite account reviews at exactly the wrong time. In other words, a cash problem can quietly become a compliance problem.
What brands should do now
For sellers caught in the affected group, the practical steps are clear. The first is to make a deliberate choice about billing rather than accepting the automatic one. For many advertisers, Pay by Invoice is the better fit, because it holds on to a slice of the float that proceeds deduction removes. The second is to rerun the numbers. A breakeven ACoS looks different once a surcharge is eating into fulfillment margins and payouts are arriving later, and campaigns that were comfortably profitable in March may need retuning. The third is to plan cash the way a chief financial officer would, mapping out when supplier deposits, freight, and ad costs go out against when Amazon disbursements come in, and lining up working capital if the gap is uncomfortable.
Amazon has consistently framed these changes as improvements to seller cash flow management. Many of the sellers living through them see the opposite, a steady transfer of timing and margin from their side of the ledger to Amazon’s. Both things can be true at once. What is not in dispute is the calendar. With the busiest selling season of the year now on the horizon, the brands that treat this quiet billing change as a serious planning event, rather than an inbox footnote, are the ones most likely to head into the fourth quarter with their advertising, and their working capital, intact.
