Amazon’s Multi-Channel Fulfillment (MCF) service is facing its largest seller exodus since launch after the e-commerce giant quietly implemented a 23% fee increase in May 2026, according to new data from marketplace analytics firm SellerMetrics. The move has accelerated a broader shift toward multichannel selling strategies, with affected sellers increasingly turning to Walmart Marketplace and TikTok Shop as primary alternatives.
The fee restructuring affects over 180,000 active MCF users who rely on Amazon’s fulfillment network to ship orders from their Shopify stores, eBay listings, and direct-to-consumer websites. Industry analysts estimate the changes will generate an additional $2.1 billion in annual revenue for Amazon while forcing many mid-market sellers to reconsider their fulfillment strategies.
“We’re seeing a fundamental shift in how sellers think about inventory distribution,” said Marcus Chen, VP of marketplace strategy at fulfillment consultancy Logistics Forward. “The MCF price hike is the final straw for sellers who were already questioning Amazon’s value proposition for non-Amazon orders.”
What’s Driving the MCF Fee Increases?
Amazon’s latest fee structure introduces variable pricing based on order volume and delivery speed, with the steepest increases hitting sellers processing 500-2,000 monthly MCF orders. Standard delivery fees jumped from $4.35 to $5.35 for small items, while expedited shipping costs rose 31% across all size categories.
The changes come as Amazon faces mounting pressure to improve fulfillment margins amid rising labor costs and warehouse automation investments. Internal documents obtained by Ecommerce Times reveal that MCF operates at significantly lower margins than traditional FBA, with Amazon subsidizing the service to maintain seller loyalty.
“Amazon is essentially telling sellers that if they want to use our world-class fulfillment network for non-Amazon sales, they need to pay a premium that reflects the true cost of service,” explained Sarah Rodriguez, former Amazon marketplace executive and current CEO of seller consultancy Marketplace Mastery.
The fee increases disproportionately impact sellers using MCF for high-volume, low-margin products—a segment that represents roughly 40% of the service’s user base according to SellerMetrics data.
How Are Sellers Responding to the Changes?
Early data suggests a significant behavioral shift among affected merchants. Walmart Fulfillment Services has reported a 67% increase in new seller applications since Amazon’s fee changes took effect, while third-party logistics providers like ShipBob and Fulfillment by Amazon alternatives have seen inquiry volumes surge 45%.
“The smart money is moving toward a diversified fulfillment strategy,” said Jennifer Park, founder of seven-figure Amazon seller Park Industries. “Instead of putting all our eggs in Amazon’s basket, we’re splitting inventory between Walmart WFS, our own 3PL, and keeping a smaller FBA allocation for Amazon-only sales.”
The migration extends beyond fulfillment services. TikTok Shop has emerged as an unexpected beneficiary, with its integrated fulfillment offering attracting sellers seeking alternatives to Amazon’s ecosystem. The platform’s seller enrollment increased 89% month-over-month in May 2026, with former MCF users representing the fastest-growing segment.

Which Marketplace Alternatives Are Gaining Ground?
The MCF fee controversy has accelerated existing trends toward marketplace diversification. Walmart Marketplace, in particular, is capitalizing on seller frustration with its enhanced onboarding process and competitive fulfillment rates.
“Walmart is rolling out the red carpet for disgruntled Amazon sellers,” noted retail analyst David Kim from Marketplace Intelligence Group. “Their fulfillment fees are 15-20% lower than Amazon’s new MCF rates, and they’re offering white-glove onboarding for sellers processing over $100K monthly.”
eBay has also benefited from the migration, particularly among sellers in niche categories where Amazon’s dominance is less pronounced. The platform’s Managed Delivery program has seen enrollment increase 34% since May, with former Amazon sellers citing lower fees and greater pricing flexibility as key motivators.
International marketplaces are experiencing similar growth. Sellers report increased success on platforms like Mercari, Depop, and Facebook Marketplace, particularly for unique or artisanal products where Amazon’s commoditized approach creates less value.
What Are the Long-Term Implications for Sellers?
Industry experts predict the MCF fee increases will accelerate the maturation of the multichannel selling landscape. Sellers who previously relied heavily on Amazon’s infrastructure are being forced to develop more sophisticated operations and diversified channel strategies.
“This is ultimately healthy for the ecosystem,” argued Chen from Logistics Forward. “Sellers who build channel-agnostic fulfillment capabilities will be more resilient to future platform changes and fee increases.”
However, the transition isn’t without challenges. Smaller sellers face particular difficulties in managing inventory across multiple fulfillment networks, often lacking the technology infrastructure and working capital required for effective multichannel operations.
“The winners in this transition will be sellers who can afford to fragment their inventory and invest in proper multichannel management tools,” warned Rodriguez. “Smaller operators may find themselves squeezed between higher Amazon fees and the complexity of managing multiple fulfillment relationships.”
How Should Sellers Adapt Their Fulfillment Strategy?
Experts recommend that affected sellers conduct a comprehensive audit of their fulfillment costs and channel performance before making strategic changes. The optimal approach varies significantly based on product categories, order volumes, and customer expectations.
For high-volume sellers processing over 2,000 monthly orders, the math often favors a hybrid approach combining Walmart WFS for marketplace sales with a dedicated 3PL for direct-to-consumer fulfillment. Mid-market sellers may benefit from splitting inventory between Amazon FBA for Amazon sales and alternative solutions for other channels.
“The key is to avoid knee-jerk reactions,” advised Park from Park Industries. “Test different combinations on a small scale, measure the total cost of ownership including storage and labor, and gradually shift inventory allocation based on actual performance data.”
Technology integration emerges as a critical success factor. Sellers increasingly rely on multichannel inventory management platforms like ChannelAdvisor, Sellbrite, and Zentail to coordinate operations across diverse fulfillment networks while maintaining accurate stock levels and synchronized pricing.
As the e-commerce landscape continues evolving, Amazon’s MCF fee increases represent more than a simple pricing adjustment—they signal a fundamental shift toward a more distributed, competitive fulfillment ecosystem where sellers must actively manage platform relationships rather than defaulting to Amazon’s comprehensive but increasingly expensive solutions.
