Top E-Commerce Development Companies in the USA

1,095 IT service providers ranked by rating, review volume and listing quality.

E-commerce development is the engineering side of selling online: building the storefront and checkout, and integrating them with payments, stock, shipping, tax and whatever finance system the business already runs. It is distinct from e-commerce strategy or marketing, though many firms sell all of it.

Integration is where these projects succeed or fail. A storefront is a well-understood problem; connecting it to an existing warehouse, ERP or accounting system usually is not, and it is where the estimate moves. Ask specifically which integrations are in scope, whether they are off-the-shelf connectors or bespoke work, and who owns them when the upstream system changes its API.

Between them, the 600 best-ranked of these 1,095 IT service providers cover eCommerce (506), web development (499), web design (425) and mobile app development (356). They also list work in California, New York, Washington and New Jersey. 592 of them have written a profile you can read before you get in touch.

TrustList ranks more than 1,000 e-commerce development companies in the USA, ordered on client reviews and profile quality, never on payment. At the top right now: Big Couch Media Group, Shimshock Group LLC and KnackForge Soft Solutions Pvt Ltd.

Hands-on experience with your platform (Shopify, Magento, WooCommerce or custom)
Payments, tax and shipping set up end to end, not left to you
A migration plan that keeps your URLs and search rankings (redirects)
How the store performs under peak traffic

How many e-commerce development companies are there in the USA?

1,095 companies on TrustList offer e-commerce development and are based in the USA. That makes the USA the largest e-commerce development market we rank.

How is this ranking worked out?

Each firm's position comes from its client reviews and its profile, blended into one score:

Rating, smoothed so a single five-star review cannot outrank a firm with hundreds of good ones
Review volume, with diminishing returns
Profile completeness: the details a buyer needs to judge the firm
Earned trust: verification and awards, as a small lift

No firm can pay for a position. Sponsored listings are labelled and shown apart from this list. How rankings work

What else do firms in the USA offer?

We also rank web development (2,396), web design (1,857) and mobile app development (1,308) in the USA.
