Amazon Tightens Margins and Liquidity for Sellers
ADZINE reports that Amazon is increasing financial pressure on its third‑party sellers through several platform changes. A planned switch would have advertisers' paid media costs automatically deducted from sales proceeds before charging other payment methods, reducing sellers' liquidity; after market pushback Amazon postponed this change to August 1, 2026 and announced supporting ad-credit programs. The change coincides with other measures—delayed payouts under a "Delivery Date + 7" model and additional logistics fees—creating a cumulative margin squeeze. Some sellers briefly paused advertising in April and are evaluating diversification (own shops, alternative channels) to reduce dependence on Amazon. The piece frames these moves as part of a wider platform-economy dynamic where retail marketplaces bundle commerce, logistics and advertising, increasing sellers' operational exposure to platform policy shifts.
Policy change from a major platform (Amazon) affecting retail media billing, seller liquidity and payout timing has broad implications for retail media economics, advertiser spend behavior and merchant dependence on the platform.

Amazon Sellers Boycott Ads Over New Payment Policies
Amazon announced a pause to a planned change in how some advertisers pay for Amazon Ads after seller backlash, deferring the change until August 1, 2026. In a message on the Amazon Ads blog, the company said it had notified a small group of advertisers that it would update their available payment methods to require payment via seller or vendor account balance or Pay by Invoice; based on feedback Amazon is giving affected advertisers more time to prepare. Amazon said the majority of advertisers already use account-balance payments and that Pay by Invoice bills monthly with net-30 terms. The update applied only to advertisers who were directly contacted. The move followed coordinated seller pushback, including calls for a one-day ad boycott, and drew comments from seller-group organizer Eugene Khayman. Amazon has previously delayed other controversial seller policies after similar backlash.
Amazon Sellers Protest Ad Policy Changes
Members of Million Dollar Sellers (MDS), a 10-year-old community of Amazon sellers, met in New York and remain frustrated after organizing a boycott earlier this year over changes to Amazon’s seller and ad platforms. The protest prompted Amazon to delay a planned ban on certain credit-card ad payments from April to August 1, 2026, but sellers say margin pressures persist from a new DD+7 payout rule, temporary fuel surcharges that may become permanent, and unwanted ad defaults sending ads off‑platform and into AI/chatbot placements they cannot fully exclude. While many sellers are testing alternatives (TikTok, Meta, Walmart, Target and direct storefronts), MDS leaders say another boycott is unlikely given legal and retaliation risks. Marketplace Pulse shows a decline in seller count between Jan 2025 and Mar 2026 even as Amazon reported seller revenue growth for 2025.
Amazon Ads Boycott Raises Existential Question for Sellers
A coalition of large Amazon sellers organized by Million Dollar Sellers paused Amazon Ads spend for 24 hours in mid-April 2026 to protest recent policy and fee changes that are squeezing seller margins. Complaints center on a 3.5% fuel surcharge, longer payment timing (Amazon waits seven days after delivery confirmation to pay sellers), and a proposed ban on credit-card payments for Amazon media and data — a change Amazon has delayed until August after pushback. Sellers argue credit-card perks and cashback materially offset thin margins. Marketplace Pulse data cited in the piece shows active seller counts falling (584,000 to 500,000) and increasing concentration of third-party GMV among fewer sellers. The author frames the boycott as a limited lever sellers can use while questioning whether it remains viable to build and scale brands primarily on Amazon amid rising costs and regulatory pressures.
