Amazon Vendor vs Seller: More Sales, Less Control?

Moving from Amazon Seller to Amazon Vendor can look like a clear sign of success. Instead of selling each unit to the end customer, Amazon buys products in volume and becomes the reseller. For a manufacturer or product owner, the appeal is obvious: larger orders, less direct handling of individual customers and access to Amazon’s commercial and logistics scale.

But the most important question is not which model looks bigger. It is this: who holds the leverage when the platform also becomes your customer and distributor?

The contrasting experiences of David Jalali and Betzold show why Vendor vs Seller cannot be judged on sales volume alone.

The basic commercial difference between Seller and Vendor

Under the Seller model, the merchant sells to the end customer through Amazon. Under the Vendor model, Amazon buys the products from the company in bulk and then sells them to the consumer.

That change in transaction structure shifts several commercial dynamics. In Seller, the company remains the seller inside the marketplace. In Vendor, Amazon becomes a major customer of the company and then resells the same product to the market.

The size of Amazon’s purchase orders, its commercial terms and the manufacturer’s dependence on those orders can therefore become direct drivers of the company’s economics.

The table is not a claim that every Vendor arrangement works identically. It shows where control and risk can shift when the business model changes.

David Jalali: when Vendor looked like the natural next step

German entrepreneur David Jalali, from Dormagen, developed a child-focused product: adhesive, anti-slip silicone plates for toddlers. He spent more than a year developing and testing the product with a local German manufacturer, aiming for high quality and strict safety standards.

When he began selling on Amazon as a Seller, demand was strong enough to keep the German factory running at full capacity. Then came the Vendor invitation.

From the product owner’s perspective, it was easy to read that invitation as a promotion. The product had proven itself, and now Amazon wanted to buy it directly in volume. Jalali described the feeling as reaching the top: no longer having to sell unit by unit, with the possibility that Amazon’s scale could multiply the business.

Then the economics changed.

According to Jalali’s account, Amazon’s commercial terms put intense pressure on his margin. At the same time, cheaper Chinese copies of his design appeared on the marketplace. Amazon later stopped buying his products. He was left with debt and large amounts of unsold inventory, and the business ended in severe losses and bankruptcy.

The commercial lesson is not that Vendor always produces this result. It is that a manufacturer that builds production around one very large buyer ties a meaningful part of its future to that buyer’s purchasing decisions.

Betzold: why a successful company can still reject Vendor

Ulrich Betzold represents the opposite decision. His family business has produced school and kindergarten supplies for roughly 50 years, and its products have been Top Sellers on Amazon. Even so, Betzold repeatedly rejected invitations to join the Vendor program.

His reasoning was not anti-growth. It was anti-dependency.

Betzold’s concern was straightforward: if his company sells the same product itself on Amazon while also selling that product wholesale to Amazon for resale, the business can end up competing with its own products inside the same marketplace.

He framed the Buy Box question bluntly: if Amazon is also selling the same product, which offer will receive the default purchase position? From his perspective, becoming both Seller and Vendor creates a conflict that can weaken the company’s independent distribution structure.

For Betzold, the bigger risk was allowing Vendor to grow so important that other channels became secondary or fragile.

“Control” is not an abstract management concept

In Vendor vs Seller, control means practical questions with direct financial consequences.

Who decides how much stock gets purchased? What happens if the largest buyer reduces or stops orders? How much margin remains after wholesale terms? Has the factory expanded capacity or inventory on the assumption that Amazon orders will continue? Are other channels strong enough that a change in Amazon demand does not become an existential problem?

Jalali’s experience answers those questions from the downside after buying stopped. Betzold’s decision answers them before entering the relationship in the first place.

Vendor growth can be real — and so can dependency

There is no reason to ignore the attraction of the Vendor model. When a customer the size of Amazon places large orders, business volume can change quickly. For a manufacturer, that can mean more production and less direct handling of individual marketplace orders.

But the same scale creates dependence. The larger Amazon becomes as a customer, the more expensive it may become to reject its terms, and the more damaging a reduction in its orders can be.

That is why Vendor is more than a choice about how to sell “on Amazon.” It is a decision about how much commercial power a company is willing to concentrate in one very large customer and distributor.

Seller does not mean full independence either

Rejecting Vendor does not remove Amazon’s influence. A Seller still operates inside a marketplace shaped by Featured Offer visibility, fees, advertising and competition.

The difference is that Amazon does not become the wholesale buyer of the same product in the same way.

So the choice should not be simplified into Seller = full control and Vendor = no control. The more useful framing is that the two models create different forms of dependency and different risk concentrations.

What should matter before accepting Vendor?

The decision needs to go beyond the size of the first purchase order.

A manufacturer or brand should ask whether the relationship makes the company stronger outside Amazon as well, or whether it increases dependence on a single customer. If growth expands production but compresses margin, builds inventory around one buyer, or creates conflict with the company’s existing Seller channel, volume alone is not enough to judge the deal.

Jalali’s case shows what can happen when the assumption of continuing purchases fails. Betzold shows why refusing a large opportunity can be a rational strategic decision when distribution independence matters more than immediate scale.

FAQ

What is the basic difference between Amazon Vendor and Amazon Seller?

Under Seller, the company sells to the consumer through Amazon. Under Vendor, the company sells products wholesale to Amazon, and Amazon then sells them to the consumer.

Why would a successful company reject Amazon Vendor?

Because larger volume can come with greater dependence on Amazon as buyer and distributor, and it can create tension with an existing Seller channel or other distribution channels.

Does Vendor mean better margins?

Not necessarily. David Jalali’s experience is an example in which Vendor terms put severe pressure on margin before Amazon stopped purchasing the product.
