About SmartSeller

We ran online stores before we built software for them.

SmartSeller was built by e-commerce operators with more than ten years of running stores — buying stock, pricing products, planning promotions and closing the month. The app is the method we used on our own stores, turned into software.

Our story

For over a decade we managed online stores the hard way: spreadsheets for costs, gut feeling for promotions, and month-end surprises. Revenue looked great while profit quietly leaked through products priced below their real cost, discounts that sold at a loss and cash frozen in stock nobody wanted.

So we built a method: know your true cost per product, set a floor for every price, protect the products that actually make money, and turn dead stock back into cash. It worked on our stores and on the stores we advised.

SmartSeller is that method, running inside your Shopify admin. It doesn't just show you numbers. It tells you what to do next, and lets you do it in one click.

What we believe

No number without a verb.

Every metric comes with the action that moves it: reprice, take it out of the offer, reorder, clear it.

Cost truth, not attribution.

We don't guess which ad gets credit for a sale. We build the true cost behind every sale, from your own Shopify data.

You stay in control.

SmartSeller never changes your store on its own. Every change is something you confirm, and you can undo it.

Simple, honest pricing.

Flat monthly plans, billed through Shopify. No per-order fees, no overage, no surprises.

Who it's for

Independent Shopify brands in the US that sell physical products, from the first few hundred orders a month to tens of thousands — founders and small teams who make pricing, promotion and inventory decisions themselves and want to make them with real margins in front of them.
