Amazon Business (B2B on Amazon)
PunchOut is the integration that lets an employee of a large organisation shop on Amazon Business from inside their company's procurement system, bring the cart back into that system for approval, and have a purchase order raised automatically. As a seller you configure nothing: a PunchOut order arrives in Seller Central like any other Amazon Business order and ships the same way. What is different is who is on the other end, and what that buyer's presence tells you about where your product could sell in bulk.
Most sellers first meet the word when a business order shows up with a purchase order number from an organisation that clearly has a purchasing department, and they wonder how a university or a hospital system found a listing. The answer is usually PunchOut. Understanding it explains a slice of your business orders, and it points at a category of buyer who is worth a direct conversation later.
What PunchOut actually is
Large organisations do not let staff buy things with a card and a receipt. They run procurement software: Coupa, SAP Ariba, Oracle, Jaggaer, Workday and similar systems that hold approved suppliers, budgets, approval chains and purchase order numbering. Every purchase has to start and end inside that system so finance can see it.
PunchOut is a standard way for a supplier's online catalogue to plug into that system. The employee opens their procurement tool, clicks the Amazon Business tile, and is sent, or punched out, to Amazon Business with their organisation's account already identified. They search and fill a cart exactly as any business customer would, including seeing your business price and quantity discounts. When they check out, the cart does not complete on Amazon. It is sent back into the procurement system as a requisition. A manager approves it, the system raises a purchase order with its own number, and only then does the order actually place on Amazon Business.
From your side, the result is a normal Amazon Business order. It shows the payment method the organisation uses, often Pay by Invoice, and it may carry a PO number that the buyer's system generated. It ships through FBA or your own fulfilment. Nothing about the listing, the price or the fees changes.
Why the seller does nothing
PunchOut is an agreement between the buying organisation and Amazon. Amazon builds and maintains the integration with each procurement platform, and the organisation's procurement team turns it on. There is no supplier enrolment for third-party sellers, no catalogue to upload, no technical work. If your product is on Amazon Business with a business price, it is available to every PunchOut buyer on the marketplace.
This is a real advantage and a real limitation. The advantage is that getting onto a large organisation's approved supplier list normally takes months of vendor onboarding: insurance certificates, tax forms, banking details, a portal registration, a security questionnaire. Through PunchOut, Amazon has already done that onboarding once for the entire marketplace, and your listing rides along. A brand with a $22 business price on a stapler-sized product can be bought by a state agency without anyone at the agency knowing the brand's name.
The limitation is that the relationship is entirely Amazon's. You cannot see which procurement system the order came through, you cannot contact the purchasing department, and you cannot become a direct supplier through the same door. The overview of Amazon Business as a B2B marketplace draws the same line for every feature of the program: the buyer is real, the order is real, the relationship is not yours.
How to recognise a PunchOut order
Amazon does not label orders as PunchOut in Seller Central. You infer it. The signals are an organisation type on the order that implies a procurement department (education, healthcare, government, a large enterprise), a purchase order number in a format that looks system-generated rather than typed by a person, payment on invoice, and delivery to a receiving address or a department rather than a named individual. Repeat orders at regular intervals in the same quantity are another clue, because procurement systems make reordering a two-click task.
The B2B reports in Seller Central break business orders down by customer segment, and that is where PunchOut buyers become visible as a pattern rather than a one-off. The seller-side view of Amazon Business accounts explains what is in those reports and what is not.
What wins on a PunchOut order
A PunchOut buyer searches Amazon Business the way any business customer does, with a few extra habits shaped by their procurement policies.
They often have supplier diversity targets, so listings from sellers with recognised ownership credentials are surfaced or filtered. Adding your certifications to your business profile matters more for this buyer than for any other; the article on Amazon Business certifications covers which ones count and how to get them.
They usually cannot buy from a seller who charges tax when their organisation is exempt, so being enrolled in the tax exemption program, which is the default, keeps you eligible.
They are guided by approved-purchasing rules that favour business-only offers and clear quantity pricing, because the approver wants to see that the employee chose the sensible option. A tidy quantity discount table on your listing is a reason for the requisition to be approved without a question.
And they need the invoice to match the PO. Because Amazon generates the invoice for the order with the PO number printed on it, this works automatically, but only if the legal name and address on your seller account are what the organisation will see and accept.
None of that is exotic. It is the same work you would do to serve any business buyer well, with slightly higher stakes because the approver never sees your brand story, only the line item.
What a PunchOut buyer tells you about your market
Here is the part that matters beyond the order itself. An organisation buying through PunchOut is a large account with a formal purchasing function. That function has approved suppliers, and those suppliers are distributors: the office products distributor, the medical supply distributor, the janitorial and sanitation distributor, the lab supply distributor, the foodservice distributor. Amazon Business is one tile on the procurement screen; the distributors are the others.
If a school district buys 60 of your storage bins through PunchOut, the district also buys from an education supply distributor every month, and that distributor has a catalogue your bins could be in. If a hospital system buys your hand sanitiser dispensers, the hospital has a medical-surgical distributor whose sales reps walk its corridors. Those distributors are the wholesale channel that serves the exact buyer Amazon Business has just shown you.
That is a different kind of information from consumer sales data. A consumer order tells you a person liked the product. A PunchOut order tells you an institution has a use for it, has approved spending on it, and buys through channels you can join. The strategy article for brand owners goes further into turning that observation into a channel plan.
Turning the signal into a direct account
You cannot email the PunchOut buyer, and you should not try to work around Amazon's rules to find them. What you can do is take the category of buyer and go to the distributors and direct accounts in that category on your own.
Start by writing down the organisation types you see in your business orders over a quarter. Then, for each, name the distributors that serve them. Many are well known within their industry and unknown outside it. Then decide which to approach direct and which to reach through a distributor, based on order size and your capacity to invoice and ship cases.
The distributor conversation will require a wholesale price, a case pack, a spec sheet and the ability to take a purchase order on net terms. The fact that institutions are already buying your product on Amazon Business, at a business price, with PunchOut-driven reorders, is the strongest proof you can bring to that conversation. Distributors want products their customers already ask for, and you have evidence of that in Seller Central.
If you want to see which distributors and stores would carry your product before you start that list by hand, paste the listing into WholesalePilot and look at the preview; it shows who would stock the product, which is exactly the set of names a PunchOut order is hinting at.
PunchOut is a technical feature on the buyer's side, invisible in your settings and quiet in your reports. Read it anyway. When a procurement system is placing orders for your product, an entire supply chain already exists for that buyer, and it has room for a brand that shows up with the right price and the right paperwork.
