How to Choose an E-commerce Development Company in 2026
The platform, integration and handover questions to ask an e-commerce development company.
Key takeaways
- 01Choose a platform first, then the company that builds on it well.
- 02Ask for the integration scope in writing: payments, shipping, ERP and any custom systems.
- 03Confirm how the company tests checkout, promotions and mobile before launch.
- 04Agree code ownership, documentation and post-launch support before the first sprint.
Start with the platform
E-commerce platforms differ in cost, flexibility and the work needed to run them. Before you compare companies, decide which platform suits your product range, your team and your integrations. A good company will tell you when another platform fits better, and why.
Scope the integrations
Most store projects fail on integrations, not on the storefront. List every system the store must connect to: payments, shipping, tax, ERP, accounting, stock and marketing tools. Ask each company how it will build and test each integration, and who maintains it after launch.
Testing before launch
Ask how the company tests checkout, discount codes, shipping rules, returns and mobile devices. A written test plan and a staging environment should be standard, not an extra.
Questions to ask
- Which platform do you recommend for us, and why?
- Which integrations are included, and which are extra?
- How do you handle staging, release and rollback?
- Who owns the code, the content and the data?
- What support is included after launch, and how fast is the response?
Red flags
- A quote with no integration list.
- No staging environment or no rollback plan.
- Claims of partner status or certifications that you cannot verify on the vendor's site.
- A team that will not show past work you can review.
What to put in the brief
Share your product count, your expected order volume, your current systems, your target markets and the features you must have at launch. A specific brief gives a more accurate written quote.
Working with Elgrith
We build e-commerce stores on several platforms, including Magento, Shopify and BigCommerce, and we connect them to the systems a business already uses. We agree the integration scope and the handover in writing, and we give a fixed quote after a free call. For Magento specifically, see our Magento agency guide.
Frequently asked questions
Should we pick the platform before the agency? Yes, unless you need a neutral view. Ask the agency for its platform recommendation with reasons, and compare it with your own requirements.
