New Advertising Payment Policy Could Tie Up 800000 in Working Capital Per Seller
Amazon is fundamentally changing how third-party sellers pay for advertising on its platform, and the financial impact is significant. Beginning in mid-2026, Amazon will deduct advertising costs directly from seller earnings rather than accepting credit card payments. For sellers like Chuck Gregorich of Net Health Shop, who sells fire pits and outdoor furniture, the change could tie up as much as $800,000 in working capital during an already tight seasonal period.
The policy shift affects thousands of sellers who have built their cash flow models around the ability to pay for ads via credit cards while collecting sales revenue on a rolling basis. Amazon said sellers can still use credit cards as a secondary option or opt for invoicing with 30-day payment terms, but the fundamental economics of seller advertising have changed. For many small and medium-sized businesses, this represents an existential challenge to their product innovation budgets.
Delivery Date Plus 7 Days Policy Delays Seller Payouts by 10 to 15 Days
Compounding the cash flow pressure, Amazon is changing its payout timing from a rolling two-week cycle to a "Delivery Date + 7 days" model. Under the new system, payment is held for seven days after an order is delivered, potentially delaying access to funds by 10 to 15 days compared to the previous arrangement. Gregorich estimates this could temporarily tie up about $1 million of his revenue.
Amazon spokesperson Ashley Vanicek stated that the change "reflects a longstanding policy" and that the company standardized its reserve system in 2016. Amazon said the delay gives customers time to receive orders, initiate returns, or file claims. However, the practical effect is a significant cash flow disruption for sellers already dealing with rising costs from tariffs, freight, and seasonal inventory buildup.
Third Party Seller Fees Generate 172 Billion for Amazon Up 11% Year Over Year
The fee structure changes come against a backdrop of escalating seller costs. Third-party seller services — including commissions, fulfillment, shipping, and advertising fees — generated $172 billion for Amazon in 2025, an 11% increase from the previous year. These services accounted for approximately 24% of Amazon's total net sales.
Amazon also imposed a 3.5% fuel and logistics surcharge on merchant fulfillment fees and hiked base fulfillment fees earlier in 2026. For sellers, these compounded cost increases are forcing a reevaluation of product sourcing, pricing strategies, and whether the Amazon marketplace remains a viable primary channel. Some sellers are diversifying to Walmart Marketplace, eBay, and direct-to-consumer channels to reduce dependence on a single platform.
"This time of the year is the worst time of the year for me for cash flow, citing inventory purchases, tariffs and freight costs that all come due ahead of peak selling season." — Chuck Gregorich, owner of Net Health Shop
Sellers Pivot to Multi Platform Strategies as Amazon Dependency Risks Grow
The cumulative impact of these policy changes is accelerating a trend toward multi-platform selling. Sellers who previously operated exclusively on Amazon are increasingly listing products on Walmart Marketplace, building standalone Shopify stores, and exploring social commerce channels. The goal is to reduce single-platform risk while maintaining the volume that large marketplaces provide.
This diversification is itself a form of product innovation. Sellers are developing marketplace-specific product variants, optimized pricing strategies per platform, and unified inventory management systems that can allocate stock across channels in real-time. The sellers who thrive in this new environment will be those who treat multi-platform distribution as a core competency rather than an afterthought.
