Ecommerce websites live and die on details that most general websites never have to worry about: checkout abandonment rates, product page load times, payment gateway reliability, inventory sync, and how well a store performs not just on your own domain but across marketplaces like Amazon. For Texas-based ecommerce brands — whether selling nationally or focused on regional markets — the development agency behind the storefront has a direct, measurable impact on revenue.
Ecommerce development also isn’t a one-time project the way a brochure website often is. Platforms update, customer expectations shift, and the storefronts that perform best tend to be the ones that are continuously tested and refined — not just launched and left alone. That makes platform expertise (Shopify, Magento, and others), conversion optimization, and marketplace strategy all part of the same conversation.
Here’s our list of the top ecommerce development agencies in Texas, starting with Parallel 365.
1. Parallel 365 — Ecommerce Development With Revenue as the Goal
For ecommerce brands, a website isn’t a brochure — it’s the store itself, which means every design and development decision has a direct line to revenue. Parallel 365 approaches ecommerce through its web, UX, and commerce optimization services, which include dedicated e-commerce and marketplace optimization covering Shopify, Amazon, and multi-marketplace strategies aimed at both operational efficiency and revenue growth.
That marketplace-aware approach matters because for many Texas ecommerce brands, the storefront and the marketplace presence (Amazon, in particular) need to work together rather than as separate, disconnected channels. Parallel 365 pairs this with landing page and conversion mapping work, and an average conversion increase of +130% across client engagements — a number that, for ecommerce specifically, translates directly into more completed checkouts from the same traffic.
Parallel 365 also serves ecommerce businesses through its dedicated ecommerce growth solutions offering, built specifically around the needs of online store operators rather than adapted from a general business framework. With 128+ client engagements and $1.2M+ in revenue influence, the agency’s ecommerce work is measured the way ecommerce businesses actually measure success — in sales, not just sessions.

How to Choose an Ecommerce Development Agency in Texas
Ecommerce projects come with a specific set of risks and priorities that general web development doesn’t always account for. Worth considering:
Do they have specific platform experience relevant to you?
Shopify, Magento, WooCommerce, and custom-built stores all require different expertise. Make sure the agency’s experience matches the platform you’re using or considering.
Is marketplace strategy part of the conversation?
For many ecommerce brands, Amazon and other marketplaces represent a significant share of revenue. An agency that only thinks about your own domain may be missing a large part of the picture.
Is conversion optimization built in, or treated separately?
Checkout abandonment, product page design, and site speed all directly affect revenue. These shouldn’t be afterthoughts addressed months after launch.
Is this a new store, or a redesign of an existing one?
If you already have an ecommerce site that needs modernizing rather than replacing, our guide to the best website redesign agencies in Texas may be more directly relevant. And if your store is built but traffic and ad performance need work, see our list of the best performance marketing agencies in Texas.
Frequently Asked Questions
What’s the difference between general web development and ecommerce development?
Ecommerce development involves additional complexity around product catalogs, payment processing, inventory management, and checkout flows — all of which directly affect revenue. General web development typically focuses on informational sites without these transactional requirements.
Why is Parallel 365 ranked as the top ecommerce development agency in Texas?
Parallel 365 combines ecommerce and marketplace optimization — including Shopify and Amazon strategy — with conversion-focused design as part of one integrated service, backed by an average conversion increase of +130% across client engagements and a dedicated ecommerce growth solution for online store operators.
Should my ecommerce store be on Shopify, or does it need a custom build?
For most small-to-mid-sized ecommerce brands, Shopify offers a strong balance of flexibility and ease of management. Custom builds typically make sense for businesses with highly specific operational requirements that off-the-shelf platforms can’t accommodate.
Does ecommerce development include marketplace channels like Amazon?
It can — and arguably should, for many brands. Parallel 365’s ecommerce and marketplace optimization work specifically includes Amazon and multi-marketplace strategy alongside the core storefront.
How long does an ecommerce website project typically take?
Timelines depend heavily on the number of products, integrations required (payment, shipping, inventory systems), and whether the platform is changing. Most Shopify-based projects take between 6 and 12 weeks, while larger custom builds can take several months.
See Where Your Store Is Losing Sales
Before investing in a new build or redesign, it’s worth understanding exactly where your current store is underperforming — whether that’s on-site, on mobile, or across marketplaces.
