Amazon Is Putting New Pressure on Sellers to Win B2B Customers
Amazon Business, the company's marketplace for procurement professionals, reached $35 billion in annualized gross sales in 2025 and is growing fast enough that Amazon is now asking third-party sellers to meet new fulfillment standards specifically for business buyers. Two changes announced this month show how Amazon is using seller performance requirements to strengthen its B2B pitch to corporate procurement teams.
The broader context is Amazon Business Reshape, the company's annual procurement conference, which returns October 27 to 28, 2026, at the Gaylord Opryland in Nashville. Now in its fifth year, the event draws procurement, finance, IT, operations, and supply chain leaders from enterprise organizations. Amazon is clearly treating B2B as a growth priority rather than a side offering, and the new seller requirements follow that logic directly.
What's Changing for Sellers
The Business Hour Delivery Rate
Starting September 30, 2026, seller-fulfilled orders to Amazon Business customers must meet a new Business Hour Delivery Rate of 90% or higher. The metric tracks the percentage of your FBM shipments delivered within a business customer's stated operating hours, measured over a rolling 14-day period.
If your BHDR falls below 90% on September 30, Amazon will issue a notification and provide improvement recommendations. If it hasn't recovered by October 30, your seller-fulfilled offers may be deactivated for Amazon Business customers. FBA offers and standard retail orders are not affected by this requirement.
The metric itself is not new. Amazon introduced the BHDR tracking tool previously as an informational metric only, with no enforcement attached. The September deadline converts it into an account health requirement with real consequences.
The core problem sellers face is control, or the lack of it. Sellers don't determine when UPS, FedEx, or USPS attempt delivery. A package can leave your facility on time and still arrive at a business address on a Saturday or during off-hours if the carrier's routing takes it there. Seller forums have reflected significant frustration with this, since the penalty falls on the seller for carrier behavior the seller cannot directly control. Amazon's recommended path for sellers who struggle to maintain the rate is to use FBA for B2B-eligible SKUs rather than attempting to manage business-hours delivery through FBM carriers.
Pallet Delivery for FBM Business Orders
Also new this month, sellers can now offer pallet delivery for Fulfilled by Merchant orders to Amazon Business customers. During Amazon's pilot program, 80% of business customers chose pallet delivery when it was offered, with most choosing it over faster shipping options.
The revenue case Amazon makes to sellers is specific: FBA pallet orders generated an average of 16 times more revenue per order than non-pallet orders, according to Amazon's 2025 research. Business buyers purchasing office supplies, industrial goods, or consumables in bulk quantities have obvious reasons to prefer pallet delivery over parcels, and the option gives sellers a way to compete for that volume without switching entirely to FBA.
Why Amazon Is Leaning on Sellers for B2B Growth
Amazon Business launched in 2015 and has grown to serve procurement teams at manufacturers, distributors, hospitals, schools, and enterprise organizations. The value proposition to those buyers is straightforward: purchasing controls, multi-user accounts, invoice payment terms, spend analytics, and a product catalog that covers categories from office supplies to industrial equipment.
What Amazon needs from sellers to make that pitch credible to enterprise procurement teams is reliability. A business buyer who orders time-sensitive materials and receives them on a weekend or after closing time has a legitimate complaint. A buyer who orders bulk quantities and gets dozens of parcels instead of a pallet has an operational problem. Both are things Amazon is now explicitly asking sellers to solve.
The Reshape conference reflects the same ambition at the executive level. Business buyers attending the two-day event will hear sessions on AI's role in procurement intelligence and how external forces are reshaping purchasing strategy, content designed for the kind of senior decision-maker who controls enterprise spend rather than the individual buyer placing a one-off order.
What Sellers Should Do Before September 30
Check your current BHDR in Seller Central now. The metric has been visible for some time even without enforcement, which means you have actual data to work from rather than guessing at your exposure.
For SKUs where your FBM operation has difficulty guaranteeing business-hours delivery, the cleaner path is moving those products to FBA before the deadline rather than trying to manage carrier scheduling. Amazon's own automation tools, including Automated Handling Time and Shipping Settings Automation, combined with Amazon Buy Shipping, are the tools Amazon recommends for sellers who want to maintain FBM eligibility for business orders. Using Amazon Buy Shipping specifically provides compliance guarantees with the BHDR requirement that self-arranged carrier labels do not.
If B2B volume is meaningful to your business, the pallet delivery option is also worth enabling now. The adoption data from the pilot suggests business buyers actively prefer it when available, and offering it puts you in a stronger position against sellers who have not yet turned it on.
