Should your brand sell on Amazon if you already have a Shopify store?

This is one of the first questions founders ask us, usually with some anxiety attached. They have built a brand on Shopify, their margins are healthy, and Amazon feels like handing their customer to someone else.

Our answer is almost always yes, with conditions. The risk is not Amazon. The risk is running Amazon and your store as two separate businesses that end up fighting each other.

Why sell on Amazon at all?

Because your buyers are already there. For many categories, Amazon is where product research starts. If a shopper searches for your category on Amazon and you are not there, they buy a competitor, or they buy your product from a reseller you do not control.

That second point gets overlooked. If your product is sold anywhere at wholesale, it can end up on Amazon without you. Owning your brand’s presence on the marketplace is often less about adding revenue than about controlling the listing, the price and the content.

Won’t Amazon cannibalize my DTC sales?

Some overlap is real. Some customers who would have bought on your site will buy on Amazon instead, often for the faster shipping.

In our experience that is usually outweighed by the customers you would never have reached otherwise. The way to know is to measure it: watch your direct site’s new customer rate and branded search as Amazon grows. If the business as a whole is gaining new customers profitably, the overlap is a cost of reach, not a loss.

How do you run Amazon and Shopify without them competing?

Give each channel a clear job, then make the decisions once, for both.

• One price architecture. Decide your price and promotion rules across channels together. Unplanned discounting on one channel trains buyers to wait for it, or to go where it is cheaper.
• Distinct offers where it helps. Bundles, subscriptions, larger packs and exclusives on your own site give buyers a reason to come to you directly.
• One inventory plan. Forecast demand for both channels together. Stocking out on Amazon costs you ranking that takes weeks to rebuild. Starving your site to protect Amazon costs you your best customers.
• One budget. Amazon ads and Meta or Google ads should be planned as one demand budget, judged on contribution margin across the business, not on each platform’s own reported return.
• One set of product facts. Names, specs, images and claims should match everywhere. It helps buyers, and it helps AI assistants that compare what they read about you across sources.

What does Amazon do to your margins?

Amazon’s referral fees, fulfillment fees and advertising add up, so margin per order is typically lower than on your own site. That is why the math has to be done at the SKU level.

Some products are strong Amazon products: they sell on search, ship cheaply and do not depend on a story. Others are better kept to your own site, where you can tell the story and keep the customer relationship. Deciding which SKUs go where is one of the highest-value calls in the whole channel strategy.

When should a brand wait?

There are good reasons to hold off: inventory that cannot support another channel, products that are expensive to ship relative to their price, or a team with no one to run the listings and advertising well. A neglected Amazon presence does real damage, because poor reviews and bad content are what shoppers and AI assistants both see.

If you are going to do it, run it as a real channel with an owner.

Frequently asked questions

Should I use Fulfillment by Amazon (FBA) or ship orders myself?

For most brands starting out, FBA is the simpler path because it makes products Prime eligible, which matters for conversion. Heavy, bulky or slow-moving items can be cheaper to fulfill yourself. Run the numbers by SKU.

Can I sell different products on Amazon and on my own site?

Yes, and it is often a good strategy. Bundles, larger packs and exclusive variants on your own site give buyers a reason to buy direct.

How do I stop unauthorized sellers from listing my products?

Register your brand with Amazon Brand Registry, tighten your wholesale agreements, and monitor your listings. Owning the official listing yourself is the strongest protection.

What about Walmart and TikTok Shop?

The same principles apply: one price architecture, one inventory plan and one budget. Add channels one at a time, and only when each has an owner.
