Why brands choose BigCommerce development specialists

The eCommerce challenges a poorly built store creates

Slow store, lost sales

A 1-second delay costs up to 7% in conversions.

Broken integrations

Disconnected tools mean manual work and missed revenue signals.

Poor mobile experience

60% of traffic is mobile. A bad UX means lost revenue.

Migration risk

DIY migrations cause data loss, broken URLs and ranking drops.

Checkout friction

Broken checkout flows are the biggest cause of abandoned carts.

Cannot scale

Stores built without architecture break under growth and traffic spikes.
Why BigCommerce

BigCommerce is designed for brands that need more than a basic storefront - multi-channel selling, B2B functionality, headless flexibility and enterprise-grade performance without the complexity of a fully custom build.

It is the platform of choice for mid-market and enterprise brands that need Shopify-level ease with significantly more power under the hood.

No transaction fees on any plan

Native multi-channel across Amazon, eBay, Meta and Google

Built-in B2B - customer groups, price lists and quotes

Headless-ready - decouple the frontend & build on any stack

Frequently Answered Questions

Everything about our BigCommerce development services

How long does a BigCommerce store build take?

A standard BigCommerce store build with a custom theme typically takes 4-8 weeks. More complex projects with headless builds, B2B functionality or custom app integrations take 8-16 weeks. We scope every project upfront with a clear timeline and milestone plan.

Can you migrate our existing store to BigCommerce?

Yes. We manage full migrations from Shopify, WooCommerce, Magento and custom platforms β€” including products, variants, customer accounts, order history and reviews. We also handle URL redirect mapping to protect your SEO rankings through the transition.

Do you build on Stencil or Catalyst?

Both. Stencil is BigCommerce's established theme framework β€” stable, widely supported and right for most builds. Catalyst is BigCommerce's newer Next.js-based framework for headless and high-performance builds. We recommend based on your performance requirements, team capabilities and long-term roadmap.

Can you integrate BigCommerce with our ERP, CRM or PIM?

Yes. We build custom integrations between BigCommerce and third-party systems including NetSuite, SAP, Salesforce, HubSpot, Akeneo and more β€” using BigCommerce's REST and GraphQL APIs alongside middleware where needed.

Do you offer ongoing BigCommerce support after launch?

Yes. Monthly retainers covering bug fixes, feature development, performance monitoring, platform updates and ongoing optimisation. We act as your extended BigCommerce development team on an ongoing basis.

Is BigCommerce right for B2B selling?

Yes. BigCommerce B2B Edition is one of the strongest B2B eCommerce solutions available. It includes customer groups, tiered pricing, price lists, quote management, purchase order support, gated catalogues and account hierarchy β€” all native to the platform without third-party apps.
