Amazon's Business Hour Delivery Rate: 90% or Your FBM Offers Go Dark

For as long as most sellers have shipped their own orders, the delivery metric that mattered was binary: did the parcel arrive by the promised date? As reported in August 2026, Amazon has added a second question for one specific slice of demand. Did it arrive while somebody was there to receive it?

The new metric is called the Business Hour Delivery Rate, and it applies to seller-fulfilled orders placed by Amazon Business customers. It measures the share of those shipments that are delivered inside the buyer's stated operating hours. As reported, Amazon requires 90% or higher, with the requirement taking effect on September 30, 2026.

"On-time used to mean the right day. For business buyers it now means the right day and an open door. A pallet sitting outside a locked warehouse at 7pm was never a successful delivery, and Amazon has finally started scoring it that way."

If you are pure FBA, this one passes you by. As reported, FBA and retail offers are unaffected. The exposure sits entirely with sellers who fulfil their own orders and who sell, knowingly or otherwise, to the Amazon Business side of the marketplace. Plenty of sellers in the second group do not realise they are in the first.

Here is the shape of the policy as described across industry coverage in August 2026. Thresholds, dates, and marketplace coverage are Amazon's to set and revise, so confirm the current wording in your own Seller Central account before you change how you ship.

The awkward part of this metric is that the last mile belongs to your carrier, not to you. You control when a parcel leaves; somebody else decides what time it lands. That makes this a routing and carrier-selection problem more than a warehouse problem.

Step five is the one sellers skip. Not every compliance requirement is worth chasing. The right answer for a seller whose Business volume is two percent of revenue may genuinely be to let those offers go and put the effort somewhere with a better return.

Every seller-performance metric Amazon has added in recent years has narrowed the definition of a successful order. Valid tracking rate asked whether you could prove a shipment moved. On-time delivery rate asked whether it landed by the promised date. Business Hour Delivery Rate asks whether it landed when the receiving business was open.

That last one is qualitatively harder, because it is the first delivery metric that depends on a piece of information you do not own: the buyer's operating hours. You can control dispatch cutoffs, carrier choice, and service level. You cannot control whether a driver reaches a trade counter at 4:45pm or 6:15pm.

What you can do is stop guessing at the aggregate. Business orders concentrate: certain regions, certain carriers, certain SKUs that ship on a slower service because they are heavy. A rate of 85% across a whole account is almost never 85% everywhere. It is usually 97% in most of the book and something much worse in one lane, and finding that lane is ordinary order-data work.

This is where multi-channel order and shipping software earns its subscription for FBM sellers. Not because it delivers parcels faster, but because it puts carrier performance, dispatch times, and destination in one view instead of three exports.
