BigCommerce Migration Service For US Stores Moving To Shopify

A BigCommerce migration service moves your store to Shopify through both platforms' APIs and rebuilds the parts that have no direct equivalent. Ours covers products, variants and option sets, custom fields, customers and addresses, customer group pricing, order history, reviews, gift card balances where your Shopify plan allows, blog content, and a complete 301 redirect map. It also covers the storefront itself, whether a Shopify theme or a headless build, plus tax, payment, shipping and ERP integrations. Everything runs from a written data map you sign off before any import code is written, and ends with thirty days of post-launch monitoring.

Most BigCommerce to Shopify migrations take between six and fourteen weeks. A straightforward catalog with a new theme sits at the short end. Stores with complex option sets, customer group pricing, B2B Edition features, several integrations or a headless frontend sit at the long end. The timeline covers an audit and data map, the storefront build, a full trial import, a timed rehearsal, the final cutover and a month of hypercare. We give you a written schedule after the audit and plan the final switch for a low-traffic window in your US time zone.

No. Passwords cannot be moved between BigCommerce and Shopify, or between most platforms, because they are stored as one-way hashes that only the original platform can check. Customer profiles, addresses, order history and group or tag assignments all migrate. After launch, customers set a new password through an account activation email. We write that email with you so it reads as a welcome to the new store rather than a security notice, time it for after launch, and stagger large lists so your sending reputation is not affected.

They need a decision per product family, not a blanket import. BigCommerce separates variant options, which create SKUs, from modifiers such as text fields, checkboxes and file uploads, which do not. Shopify supports up to three options per product, and non-variant inputs become line item properties or a product options app. A product with four or more real options gets split into separate products or has options combined. Modifiers with price adjustments need extra care so the charged price matches. We model these cases with you during the data mapping stage, before anything moves.

They move, but into a different structure. On Shopify Plus, BigCommerce customer groups and price lists map to B2B companies, locations and catalogs, with payment terms and draft-order quotes available natively. On other Shopify plans, groups become customer tags combined with a discount or wholesale app. BigCommerce B2B Edition features such as shopping lists and multi-step approval flows may need an app or a custom build. We export every group rule, including undocumented category discounts, and test real carts against the old prices so no trade customer sees a surprise on day one.

Treat the migration as an SEO project from the first day, not a launch-week task. First, crawl the live store and export your Search Console landing pages so you know which URLs actually earn traffic. Second, map every old URL to its closest new equivalent with a single 301 redirect, because Shopify moves products under /products/ and categories under /collections/, so almost every URL changes. Third, carry across titles, meta descriptions, image alt text, structured data and internal links. Fourth, load the redirects before DNS moves and test them on staging. Fifth, watch Search Console daily for a month after launch and fix any 404s the same day. Expect some short-term movement even when all of this is done right.

Yes. Historical orders import into Shopify as archived orders, so they show in the admin and in customer accounts for reorders and support. We import them without sending notifications or touching inventory. Product reviews are exported from BigCommerce or your reviews app and imported into the Shopify reviews app you choose, keeping dates, star ratings and verified-buyer status where the app supports it. Both are checked against the source counts after the trial import, so you can confirm nothing is missing before we schedule the final cutover.

Usually, but the method depends on your Shopify plan, so we confirm it before promising anything. Gift card codes and remaining balances are exported from BigCommerce and recreated as Shopify gift cards, either in bulk through the API where your plan permits it or through a gift card app where it does not. Customers keep using the same codes after launch. Balances are exported during the final content freeze so cards used in the last days before cutover carry the correct amount. We reconcile totals between the two systems and share the report with you.

We rebuild your sales tax setup on Shopify before launch and test it against real addresses. If you use Avalara on BigCommerce, you can keep it through Avalara for Shopify, or move to Shopify Tax if it covers your needs. We carry over the states where you have nexus, product tax codes, and exemption certificates for wholesale or tax-exempt customers. Test orders are placed to addresses in each nexus state to confirm the correct rate is charged. We do not give tax advice, so your accountant should confirm the nexus list, but the configuration work is ours.

Not published ones. None of our 37 public case studies is a BigCommerce migration, and we will not invent one to fill the gap. Some migration clients do not allow publication, so we share relevant references privately on a call, where you can ask about data mapping, redirects and cutover in detail. Our published Shopify work includes Future Roots, a plant store with OTP login and a one-page checkout, and Wayuvega, a Shopify app for logistics. Since 2014 we have delivered more than 150 projects across seven countries, with a 4.9 average client rating.

Yes, though the frontend is a rebuild rather than a migration. A headless BigCommerce storefront built in React or Next.js talks to BigCommerce's own APIs, so its data layer has to be rewritten against Shopify's Storefront API. We rebuild it on Hydrogen or Next.js depending on your team and content setup, keep URLs identical where the new routing allows, and redirect the rest. The data migration runs in parallel with the frontend rebuild. Our headless commerce agency page covers the Hydrogen versus Next.js decision in more detail, including the running costs after launch.

It depends on five things more than on product count: how many custom fields and option sets need remapping, whether customer group pricing or B2B price lists have to move, how many apps need replacing, how much of the theme is rebuilt rather than restyled, and how many integrations (ERP, 3PL, marketing) have to be reconnected. A small catalogue with a standard theme is a short project. A store with B2B pricing, a custom theme and an ERP link is several times the work. We send a written quote after the audit and data map, so the price covers what your store actually has.
