What makes BigCommerce

Businesses often turn to BigCommerce development services for B2B, multi-storefront, and other complex projects. The platform gives them several practical reasons to do so.

What our clients ask about
BigCommerce development

Do you migrate from Shopify or Magento to BigCommerce?
Yes. We migrate stores from Shopify, Magento, and other platforms to BigCommerce, including data, integrations, redirects, and business logic that need to carry over or be adapted for the new platform. We also handle BigCommerce to Shopify migrations when a project calls for a move in the other direction.
Do you build BigCommerce B2B stores with complex logic?
Yes. Our B2B e-commerce development covers pricing, account, quoting, and purchasing rules, then add custom development when your logic goes beyond the built-in B2B features.
Can you build headless/multi-storefront BigCommerce sites?
Yes. We build headless storefronts with Catalyst or a custom frontend and connect them through BigCommerce APIs. Multi-storefront projects can support separate brands and markets while keeping management in one BigCommerce admin.
What’s the typical timeline for a BigCommerce project?
A focused BigCommerce storefront can take around 2–4 months. Larger projects with B2B logic, multiple storefronts, integrations, or migration work can take 6–12 months. These are average numbers a BigCommerce development agency can share without context. The more details you provide, the more detailed our estimate will be.
Can you connect BigCommerce to marketplaces or other sales channels?
Yes. We connect BigCommerce to marketplaces and other sales channels using existing apps where they fit and custom API integrations when the connection needs its own logic.

    First, you decide whether headless is the right move. Then comes the better question: which setup will not make you regret that decision later?
