BigCommerce to Shopify

A closer move than most — with a few sharp edges.

BigCommerce and Shopify are both hosted platforms, so the infrastructure worries largely disappear. The real work sits in the differences: how product options behave, how pricing is segmented, and how a Stencil storefront becomes a Shopify theme.

Scope

What we help with

The work that typically sits inside this service. Every engagement is scoped to what your store actually needs.

  • BigCommerce store and catalog audit
  • Option sets, modifiers, and variant rules mapped to Shopify options
  • Price lists and customer group pricing translated to a Shopify approach
  • Custom fields migrated into Shopify metafields
  • Stencil theme rebuilt as a Shopify Online Store 2.0 theme
  • Customers, orders, and content pages
  • App and integration replacement
  • URL structure mapping and redirects

Our approach

Options and modifiers are where this migration bites.

BigCommerce lets a product carry modifiers that do not create variants — a text engraving field, a surcharge option, a dropdown that adjusts price without producing a separate SKU. Shopify's model is variant-based and stricter. Every product using modifiers needs a decision, and making those decisions before the import is what separates a clean catalog from a messy one.

  • Modifier-by-modifier catalog review

    Products using non-variant modifiers are identified and given an approach — real variants, line item properties, or an app — rather than being flattened at import.

  • Price lists translated, not assumed

    BigCommerce price lists and customer group pricing map to Shopify B2B, apps, or custom logic depending on your plan. We confirm which before scoping.

  • Stencil to Online Store 2.0

    Stencil templates do not port. The storefront is rebuilt as a sectioned Shopify theme, which is also the natural moment to fix what the old theme constrained.

Deliverables

What’s included

What you receive from an engagement of this type. Exact deliverables are confirmed in the scope we agree together.

Typical scope7 deliverables
  1. BigCommerce catalog audit

    Products, option sets, modifiers, and custom fields documented as configured, including variant counts.

  2. Option and modifier mapping plan

    Each non-variant modifier assigned an approach on Shopify, with the trade-offs written down.

  3. Pricing and customer segmentation plan

    Price lists and group pricing mapped to a Shopify capability, with plan eligibility confirmed.

  4. Shopify theme implementation

    A sectioned Online Store 2.0 theme replacing the Stencil storefront, built for your merchandising needs.

  5. Metafield structure

    BigCommerce custom fields mapped to Shopify metafields so the storefront can still render them.

  6. Redirect map

    BigCommerce URL patterns inventoried and mapped to Shopify paths, exceptions listed.

  7. Staged import and validation

    Imports run into a staged store and checked against source counts and samples before cutover.

Shopify B2B and catalog-level pricing depend on the merchant's plan and Shopify's platform rules. We confirm what your plan supports during discovery rather than assuming parity with BigCommerce price lists.

Ideal fit

Built for

BigCommerce merchants usually move for the ecosystem and the day-to-day experience rather than for infrastructure reasons.

  • 01

    Merchants who want Shopify's app ecosystem and checkout

    Teams finding theme and merchandising changes slower than they should be

  • 03

    Brands standardizing several storefronts onto one platform

  • 04

    Businesses whose agency or hiring pool is Shopify-centric

FAQ

BigCommerce to Shopify FAQs

Direct answers to what teams ask before starting this kind of work.

They need an explicit decision, because Shopify's model is variant-based. Depending on the modifier, the answer is a real variant, a line item property for things like engraving text, or an app for surcharge-style options. We identify every affected product during discovery so nothing is flattened by surprise at import.
