How to choose the best ecommerce platform for your online store: questions to ask vendors

This guide is for a small business choosing a platform to run an online store: product pages, checkout, payments and orders. The best one is the one with total fees you can afford at your sales level, payment methods your customers use, and a store you can take with you if you leave. The questions below help you compare vendors in the same way.

In this guide, a vendor is a company that sells an ecommerce platform (software for running an online store).

Why a sales demo is not enough

An ecommerce demo shows a beautiful store with a smooth checkout. The problems show up later, for example:

So ask about these in writing, and ask every vendor exactly the same questions. Then you can compare their answers directly.

Before you contact any vendor

Write down your answers to these four points. They decide which questions in the checklist matter most to you.

The checklist

The questions are in three groups. Must have means a problem here can cost you sales, break tax rules, or make it costly to leave. Nice to have means it makes a real difference for many people. Optional means it only matters to some people. When you open the checklist in NeutralPick, you can move any question to a different group to match your answers above.

The button opens this checklist in NeutralPick. There you can:

  1. Remove the questions that don't matter to you, add your own, and move questions between groups.
  2. Add each vendor you are considering.
  3. Send each vendor its own private link, so they answer every question in writing. Or, if you have already had a sales call or a product demo with a vendor, fill in their answers yourself from what they told you.
  4. See every vendor's answers side by side.

Answers to look at carefully

Vendors often answer the points below in vague terms. When you get a vague answer, ask the follow-up question shown here. A vague answer often means the honest answer is "no" or "only partly".

What to do with the answers

  1. Put all the vendors' answers side by side.
  2. Look at the Must have questions first. If a vendor answers No to something you marked as a must-have, remove that vendor.
  3. If a vendor answered "Partial" to a must-have, ask them exactly what is missing.
  4. Set up a few real products in the trial of each one left and place a test order on your phone.
