BigCommerce to Shopify migration service.

What you get

• Products with variants, SKUs, prices, cost, weight, stock and barcodes mapped to Shopify fields.
• Images with order and descriptions kept, re-hosted on Shopify.
• Categories turned into collections, brands into the vendor field.
• Customers and customer groups (the groups become tags), and optionally order history.
• Content pages and blog posts.
• A redirect file built from your BigCommerce custom URLs, and a QA report.

How it works

1. Export products from the control panel with the Bulk Edit template, plus customers, and send them with a list of the apps you use.
2. We send a fixed quote and a mapping sheet.
3. The AI engine builds the Shopify import files; a person reviews all outputs against your export.
4. We load to an unpublished Shopify store via a staff account, and you check it.
5. You approve, we add redirects, you change DNS, and we test after launch.

BigCommerce quirks that shape the mapping

Custom fields are often where BigCommerce stores spec data such as material or compatibility. We turn those into metafields so the data stays usable.

URLs and redirects

BigCommerce product URLs are custom, human-readable and typically root-level, for example /linen-throw-grey/, with categories likewise at the root such as /throws/. Shopify adds prefixes: /products/ and /collections/. Because products and categories both sit at the root on BigCommerce, a redirect cannot be guessed by pattern. Each one comes from your actual URL list.

Redirect from,Redirect to
/linen-throw-grey/,/products/linen-throw-grey
/throws/,/collections/throws
/blog/spring-styling/,/blogs/news/spring-styling

We export every custom URL from the catalog, include brand pages and blog posts, and test samples. Method details are in our BigCommerce import guide and redirect guide.

SEO protection

• Crawl your live store and pull Search Console data first.
• Carry over page titles, meta descriptions and alt text.
• Reuse slugs as handles.
• Check structured data and canonical tags once the new theme is in place (a designer task).
• Resubmit the sitemap and review 404s for two weeks after launch.

What we do not do

We do not build themes or custom apps, and we do not rebuild BigCommerce-specific apps such as bespoke ERP connectors. We map the data, and recommend developers or Shopify apps where functionality has no equivalent.

What does not transfer

Be ready for these before you start. Your Stencil theme and any theme edits do not move. BigCommerce apps and widgets need Shopify equivalents. Product reviews can move only if the review app you choose accepts a CSV import, which we confirm before quoting. Shipping zones, tax rules and payment gateways are set up again in Shopify by you. We give you a list of each, taken from your store, so nothing surprises you after launch.

Cutover and downtime

BigCommerce stays live while we build and test on an unpublished Shopify store. Near launch we agree a window, you pause catalog and customer changes, we export once more for recent orders and sign-ups, load redirects, and you repoint DNS. Choose a quiet trading day, and keep BigCommerce available as a reference afterwards.

Timeline factors

The big ones are modifier count, whether products exceed three options, customer group pricing, catalog and image volume, order import, and the speed of your approvals.

Pricing

A fixed quote follows file inspection. See pricing and store migration.

Is this a fit?

It fits stores using BigCommerce options and custom URLs that want a clean data move without losing rankings. If your business leans on B2B group pricing or deep modifiers, expect an app or developer cost on top of ours. A small store of simple products can use a free import app.
