Development

BigCommerce builds, and honest platform advice.

BigCommerce is a capable platform for merchants who want built-in B2B, multi-storefront and fewer app fees. We build and optimise BigCommerce stores, integrate them with the rest of your business, and — when a merchant has decided to move — migrate them to Shopify without losing catalogue, customers or rankings.

If this sounds familiar

  • The theme was customised piecemeal and now nobody dares change it.
  • Product pages and checkout convert below what the traffic deserves.
  • Integrations with inventory, accounting or marketplaces are manual.
  • You are weighing a move to Shopify and want a clear-eyed comparison.

What changes

  • A Stencil theme in version control, fast and easy to change.
  • Product, category and checkout experiences built for conversion.
  • Integrations that keep inventory, orders and accounting in sync.
  • A migration plan to Shopify if that is the decision — with risks and costs laid out.

What's included

BigCommerce Development, in practice.

  • 01

    Stencil theme development

    Custom themes and components built on BigCommerce’s theme framework.

  • 02

    Headless storefronts

    Catalyst / Next.js storefronts on BigCommerce APIs for stores that need them.

  • 03

    Integrations

    ERP, CRM, accounting, 3PL and marketplace connections via the BigCommerce API.

  • 04

    Performance and conversion

    Speed, product page structure, search, navigation and checkout optimisation.

  • 05

    B2B and multi-storefront

    Customer groups, price lists, quotes and additional storefronts configured.

  • 06

    Migration to Shopify

    Products, customers, orders, URLs and SEO moved with a zero-downtime cutover.

Built in version control, changed on staging

BigCommerce stores accumulate risky, undocumented theme edits over years. We bring the theme into Git, stand up a staging store, and make every change there first. Deploys become routine instead of nerve-wracking.

Conversion on the platform’s strengths

BigCommerce’s built-in faceted search, customer groups and B2B features are strong when configured well. We tune product pages, navigation, search and checkout to what your analytics show, rather than adding apps.

When the decision is to move

If you have decided on Shopify, we run the migration end to end — catalogue, customers, orders, URLs, SEO — with a zero-downtime cutover and post-launch monitoring. The BigCommerce to Shopify page explains the process step by step.

How it works

Six steps, one team, measured on outcomes.

Typical timeline: 2–8 weeks. Progress lands in your channel every week.

  1. 01

    Discover

    A 30-minute review of your stack, your numbers and what is manual today. You get a written scope — not a pitch.

  2. 02

    Architect

    Systems designed before code: data flow, integrations, where the human gates sit, and what we will measure.

  3. 03

    Build

    Short sprints in your repositories and accounts. Typed, versioned, reviewable — progress lands in your channel.

  4. 04

    Test

    Shadow runs, edge cases and load. Every pipeline proves itself against real data before cutover.

  5. 05

    Launch

    Deployed behind CI with monitoring on. A runbook and a recorded handover ship with it.

  6. 06

    Improve

    30 days of fixes included, then an optional retainer — one prioritised queue across every service.

FAQ

BigCommerce or Shopify?

BigCommerce when built-in B2B, multi-storefront or lower app costs matter and your team is happy with its editor. Shopify when you want the largest app ecosystem, the strongest checkout and the easiest hiring. We build both; the recommendation is about your store, not our preference.

Can you work on our existing theme?

Yes. We bring the theme into version control, set up a staging copy and make changes there first — so the live store never sees a half-finished change.

Do you do headless BigCommerce?

Yes, with Catalyst (Next.js) on BigCommerce’s APIs — for stores whose content or performance needs justify it. Most stores are better served by a well-built Stencil theme.

How does migration to Shopify work?

Catalogue, customers, orders and content are exported and mapped, URLs are redirected, metadata and reviews are carried over, and cutover happens with no downtime — see our BigCommerce to Shopify migration page.
