Who we are: a custom ecommerce development company
Custom Ecommerce is a custom ecommerce development company that does one thing: engineer online stores that sell. We design, build, integrate and support ecommerce platforms for direct-to-consumer brands, B2B distributors and enterprise retailers.
Our team has spent 15+ years in commerce engineering and delivered 350+ ecommerce projects across 24+ verticals, from fashion and beauty to industrial supply and energy equipment. We are based at 11200 Richmond Ave in Houston, Texas, and we work with brands across the US and internationally.
Clients come to us at different stages. Some are launching their first serious store after outgrowing a template. Others are established brands replatforming from Magento, consolidating regional sites or connecting a B2B portal to their ERP. The common thread is that the store has become important enough to need real engineering.
We are deliberately not a general digital agency. We do not run ad campaigns or produce brand videos. Every person on the team works on ecommerce strategy, design or engineering, so the advice you get is specific and practical.
What our ecommerce development company does
We cover the full lifecycle of an online store, from platform choice to post-launch optimization. Most clients use us for several of these services over time.
- Strategy and consulting: platform selection, audits and technical roadmaps.
- Design: conversion-focused UX and UI, prototyping and design systems.
- Development: Shopify and Shopify Plus, Magento and Adobe Commerce, WooCommerce, BigCommerce, Salesforce Commerce Cloud, headless and fully custom builds.
- Integration and migration: ERP, payments, marketplaces and SEO-safe replatforming.
- Growth and support: speed optimization, SEO, accessibility, analytics and maintenance.
When off-the-shelf platforms cannot model your business, our custom ecommerce website development team builds exactly what you need.
How we work with clients
We work in fixed-price milestones with senior people on every project. You always know what is being delivered, when and for how much.
Every project follows the same six phases: Discovery & Strategy, Conversion UX/UI Design, Architecture & API Engineering, Custom Development, Testing & Optimization and Zero-Downtime Launch. A typical build takes 8–16 weeks. Our ecommerce website development process page explains each phase and its deliverable.
- Transparent scope: milestones and deliverables agreed before work starts.
- Direct access: you talk to the engineers and designers doing the work.
- Visible progress: a staging store you can review throughout development.
- Full ownership: you own 100% of the code, designs and intellectual property.
- Confidentiality: a mutual NDA is available before you share details.
Our values as an ecommerce engineering team
Our values come from what clients have told us they missed with previous vendors. They shape how we scope, build and communicate.
Engineering before decoration
A store that looks beautiful but loads slowly or breaks under traffic is a liability. We design within performance budgets, targeting Google's Core Web Vitals thresholds of LCP ≤ 2.5s, INP ≤ 200ms and CLS ≤ 0.1.
Honest recommendations
We recommend the platform that fits your business, even when it is the simpler and cheaper option. Sometimes the best answer is to improve the store you already have.
Accessibility and security by default
We build to WCAG 2.1/2.2 AA and follow secure development practices aligned with our ISO 27001 certification, rather than treating either as an add-on.
Long-term partnership
A 98% client retention rate reflects our focus on relationships that outlast the launch. Many clients return for a redesign, a new region or a B2B channel years after their first project, and we treat their codebase as if we will be maintaining it for the long term, because we often are.
Credentials, partners and certifications
We hold partner status with the major commerce platforms and certifications for cloud architecture and information security.
Our partnerships give clients access to platform roadmaps, support channels and proven practices. They also hold us to the standards each platform sets.
| Credential | What it means for you |
|---|---|
| Shopify Plus Certified Partner | Experienced delivery on Shopify Plus checkout, B2B and expansion stores |
| Adobe Commerce Solution Partner | Proven Magento and Adobe Commerce architecture for complex catalogs |
| BigCommerce Elite Partner | Deep BigCommerce and B2B Edition implementation experience |
| AWS Well-Architected | Cloud infrastructure designed for reliability, security and cost control |
| ISO 27001 | Information security management applied to client data and code |
Our Houston office and the clients we serve
Our office is at 11200 Richmond Ave, Houston, TX 77082, in the Westchase district. Houston clients can meet us in person for workshops and reviews; clients elsewhere work with us by video on a shared schedule.
Being based in Houston gives us direct experience with the city's mix of energy, industrial distribution, healthcare and retail businesses. That B2B depth carries over to national clients, as our SAP-integrated B2B portal case study shows.
