How mid-market distributors compete with Amazon Business (2026)

Amazon Business crossed roughly $83 billion in gross sales in 2025 — and that's still only about 1% of US B2B ecommerce. The headline isn't that Amazon is taking over distribution. It's what its growth reveals about how your customers now expect to buy: fast, self-serve, and without waiting on a person. Here's how a mid-market distributor competes without trying to become Amazon.

What the buyer actually changed

The shift isn't really about Amazon. It's about expectations Amazon normalized. Recent B2B research finds essentially all buyers now want to self-serve at least part of the purchase, a large majority are willing to place five-figure orders through self-service channels, and analysts expect more than half of million-dollar transactions to run through digital self-serve. Your customer's procurement person has an Amazon tab open and wonders why ordering from you takes an email and a wait.

Where you win that Amazon can't

You are not going to out-catalog or out-logistics Amazon. You don't need to. What you have that a marketplace doesn't:

• You know their parts. The interchange, the cross-reference, the "they always mean the 3-inch when they say the big one." That knowledge is a moat.
• You give real terms and real service. Net-30, a human who picks up, a rush handled as a favor. Marketplaces don't.
• You can be fast on their way of ordering. Amazon makes them come to a website. You can make ordering fast and painless on the channels they already use — email, phone, a quick PDF — if you stop making those slow.

That last point is the one distributors miss. Competing with self-serve doesn't only mean "build a web store." It means removing the friction and delay from every way your customers already order.

The friction that loses you the order

A customer emails a PO at 4:50pm. It sits until someone keys it in the next morning. That lag — not price — is what makes a busy buyer try the marketplace next time. When inbound orders are read and drafted the moment they arrive, you match the responsiveness that made self-serve attractive, using the channel your customer already trusts. SideQuest reads the emailed PO from Gmail, matches every line to your QuickBooks catalog, and drafts the Estimate for a quick human review — so "I emailed it" gets the speed of "I ordered it online," without asking the customer to change anything.

A realistic competitive stance

1. Make your existing channels fast. Inbound email and phone orders should become drafted orders in minutes, not next-morning. This is the move with the biggest payoff and the lowest cost.
2. Offer self-serve where it fits — a web store or portal for the customers who want it — but don't bet the business on forcing everyone onto it.
3. Lean on what you know: cross-references, terms, service. Automate the busywork so your people spend time there instead of on data entry.

The distributors who lose to Amazon Business aren't the ones without a marketplace listing. They're the ones who made ordering slow and let a faster option teach their customers a new habit.
