What to Check Before You Choose Ecommerce Software

Ecommerce platforms all promise the same thing on their homepage: an easy way to start selling online. What they don't put on the homepage is where the real costs and constraints show up once you're actually running a store — and those are the details that decide whether you'll be happy with the choice a year from now.

Before you compare feature lists, run any ecommerce platform through the questions below. They matter more than almost anything in the marketing copy.

What Are the Real Transaction Fees?

Almost every ecommerce platform advertises a monthly plan price, and almost every one of them also takes a cut of transactions on top of that — unless you use their own in-house payment processor. That second fee is easy to miss when you're comparing plans, and it compounds with every sale. Always ask: what's the all-in cost per transaction, not just the subscription price?

How Locked In Are You to a Payment Processor?

Some platforms let you use any payment processor you like. Others charge a real penalty — sometimes a meaningful percentage — if you don't use their own. If you already have a preferred processor, or expect to negotiate better rates as you grow, check this before you commit, not after.

What Are the Inventory and Catalog Limits?

Entry-level plans often cap the number of products, variants, or storage locations you can manage. This rarely matters on day one and matters a great deal once you're expanding a product line or managing stock across more than one location. Check the limit on the plan you'd actually be able to afford at scale, not just the cheapest tier.

How Hard Is It to Leave?

This is the question most people skip entirely. Migrating an ecommerce store — products, customer data, order history, SEO rankings — is disruptive and expensive no matter which platform you're moving from or to. Some platforms make data export straightforward; others make it deliberately painful. You're not choosing a platform for today; you're choosing how hard it will be to change your mind later.

• Can you export your product catalog and customer list in a standard format?
• Do you own your domain and content, or is it tied to the platform?
• What happens to your SEO rankings if you migrate to a new URL structure?

"The cheapest plan today is not the same question as the cheapest total cost once you factor in fees, limits, and how hard it is to leave."

Does It Match How You Actually Sell?

A platform built for high-volume, low-touch retail behaves differently from one built for a small catalog of higher-priced, considered purchases. Match the platform's strengths — checkout speed, product page flexibility, subscription support, wholesale features — to how your specific store actually sells, not to whichever platform is most popular in general.

Putting It Together

None of these checks are exciting compared to browsing themes and imagining your finished store. But they're the difference between a platform that quietly costs you money and flexibility for years, and one that fits the business you're actually building. Get the fee structure, the lock-in, and the limits answered honestly before you sign up — not after your catalog is already live.
