Hire BigCommerce Experts

Hire Expert BigCommerce Developers

BigCommerce runs the platform, so developer time goes on three things: a Stencil theme, a Catalyst storefront on Next.js, or integrations through its APIs. Those are different skills. Tell us which you have, and we place a developer suited to it, starting with a look at the apps and scripts your store already runs.

Stencil or Catalyst
A theme where it does the job; Next.js where the design demands it
Rate limits respected
All apps on a store share one API limit, so that gets checked first

What a BigCommerce developer works on

On a hosted platform the code you own is a thin layer, so the skill lies in knowing what the platform already does and building only what it cannot.

Theme work in Stencil

Handlebars templates and SCSS, staying close to an updatable base theme. Most speed problems are not in the theme itself, but in scripts from overlapping apps, so that list comes first.

Headless storefronts on Catalyst

Catalyst is a Next.js storefront using the GraphQL Storefront API. It suits a design a theme cannot reach, and it adds hosting and front-end upkeep that a Stencil store does not have. Someone should argue for it first.

Integrations that respect the limits

ERP and CRM sync through the REST APIs and webhooks, inside a rate limit that all apps on the store share. Queues, retries and a way to spot a missed order all belong in the design from the start.

How to judge a BigCommerce developer in one call

  • Ask what they would look at first on a slow store. Installed apps and scripts should come up
  • Ask when Catalyst is worth the extra upkeep, and when Stencil is enough
  • Ask how they would keep an integration within the store's API limit
  • Ask how they make a webhook handler safe when an event arrives twice
  • Ask how they would handle products with many option combinations in a migration

How a BigCommerce engagement runs

Your developer is part of our engineering team in India with 3โ€“5 hours of overlap with the UK and Europe; US calls by appointment.

What to send us

Your plan, whether you are on Stencil or Catalyst, your installed apps, and the systems the store talks to. After a call we confirm who is available and a start date.

Start small if you can

Hosted platforms need less steady development. Hourly billing suits most theme and app work, with a monthly developer when you have a real backlog or a Catalyst build.

Migrations are quoted

A move to BigCommerce has an end, so we scope it and give a fixed price. Our BigCommerce migration page sets out what to plan early.

About our proof

Most of our work is delivered under NDA, so many projects cannot be named. We have no public BigCommerce case study, so ask us on the call about work like yours.

Frequently Asked Questions

Common questions about hiring BigCommerce developers from itmarkerz.

What skills should a BigCommerce developer have?
For a Stencil theme, Handlebars templates and SCSS. For a Catalyst storefront, Next.js and the GraphQL Storefront API. For integrations, the REST APIs and webhooks. Tell us which applies so the developers we propose match it.
Do you develop custom BigCommerce apps?
Yes, when an app from the marketplace doesn't fit. All apps on a store share its API rate limit, so the developer checks what is already running on your plan first.
Can a hired developer move our store to BigCommerce?
Yes, as scoped work. Products with many option combinations and customer passwords are the two things to plan early, and our BigCommerce migration page explains why.
Can they work with our existing app stack?
Yes. The first task is usually a list of installed apps and any scripts in the theme, because overlapping apps often cause the slowdowns and conflicts a store owner notices.

Tell us which of the three you need

Theme, storefront or integration, or say if you are not sure. We reply within one business day (IST) and suggest the smallest engagement that fits.
