THE REAL PROBLEM
Your customers don't see separate services. They see one store.
They experience one buying journey.
They find a product, compare options, check out, wait for delivery and decide whether to come back. If the design, the tech and the marketing are handled by different teams, the gaps show up in that journey as slow pages, broken integrations and lost repeat orders.
That's why our ecommerce development services are planned around the full journey, not handed off between agencies.
We connect design, technology, and commerce around that complete journey.
UX-FIRST COMMERCE
Start with your customers. Build around how they buy.
Before we choose features or apps, we look at your customers, your products and your data. What do people search for? Where do they drop off? What makes them come back?
The answers shape the store: clearer navigation, faster product pages, simpler checkout and the right follow-up after the first order.

PROCESS
How we deliver ecommerce projects, step by step.
Every project follows the same five stages, whether it's a new Shopify store, a migration or a growth programme.
-
01. 01. Discover & audit
Understand the business first.
We review your store, analytics, catalogue, systems and competitors, and agree goals, scope and timeline in writing.
-
02. 02. Plan the architecture
Get the structure right before building.
Sitemap, collections, URLs, integrations, data and SEO are planned up front, so nothing needs rebuilding later.
-
03. 03. Design & build
Turn the plan into a working store.
Mobile-first design, then Shopify development in short sprints with demos your team can review and test.
-
04. 04. AI & automation
Make the store do more of the work.
We add automation, AI agents and recommendations where they save time or bring in sales.
-
05. 05. Launch & grow
Launch day is the start.
QA, 301 redirects and a monitored launch, then support, CRO and growth work every month.

BEFORE YOU ASK
Ecommerce services questions, answered.
Still unsure? Write to us at hi@bristm.com and a human will reply.
Ecommerce development services cover everything needed to sell online: store design and development, platform migration, integrations with your business systems, ongoing support and growth marketing. BRISTM provides all of these on Shopify and Shopify Plus, so one team is responsible for the whole store.
New brands usually start with Shopify store development. Brands on another platform need Shopify migration. Wholesalers need B2B. Live stores that want more sales need growth marketing or managed support. On a free call we look at your store and tell you which service fits.
Cost depends on scope: a store on a customised theme costs less than a fully custom or Shopify Plus build. BRISTM gives a fixed quote after discovery, with build projects starting from $5,000. Support and growth marketing are priced as monthly plans.
A Shopify store on a customised theme usually takes 8–10 weeks. A fully custom store takes around 3–6 months, and Shopify Plus, B2B or headless builds can take longer. We confirm the timeline after a discovery call.
Yes. We move products, customers, order history and content, map every old URL with 301 redirects and keep metadata in place. Your current store keeps trading until the planned go-live.

Yes. Shopify B2B supports company accounts, price lists, volume pricing and payment terms, and Shopify Plus adds more catalogues and features. We connect it to your ERP so trade buyers can reorder online without calling your sales team.
Agentic commerce means AI assistants such as ChatGPT, Copilot and Gemini can find and buy products for shoppers. Shopify's Agentic Storefronts list your products there; we make sure your product data is complete enough to be recommended.
Yes. Our managed Shopify support covers fixes, updates, speed checks and new features on a monthly plan, handled by the team that built your store.
