BigCommerce to Shopify Migration

Most BigCommerce migrations we run land between 8 and 16 weeks. A store with a clean catalog and a straightforward theme rebuild sits at the short end; multi-storefront consolidation, B2B, or ERP integration pushes toward the long end. The assessment gives you a dated plan, and the largest schedule risk is usually decision latency on the client side, so we front-load every decision into discovery.

Our proposed bands for 2026: $15,000 to $30,000 for straightforward stores, $30,000 to $70,000 for mid-market projects with integrations and a custom theme, and $70,000 to $150,000+ for complex or Shopify Plus scope. The drivers that matter on BigCommerce specifically are variant and modifier complexity, storefront count, B2B, and custom Stencil functionality. You get a fixed quote after the free assessment, not an estimate that grows.

Every URL changes in this migration because Shopify enforces its /products/ and /collections/ paths, so the redirect map is the whole game. We build it from your sitemap, a full crawl, and Search Console data, load it before cutover, and verify it by re-crawling the old URLs after. Some position movement in the first weeks is normal on any replatform. Sustained loss is not, and our pre/post parity checks are designed to catch the causes early.

It depends on what you use today. If you rely on customer group pricing, B2B workflows, multiple storefronts, or checkout customization, Plus is usually the honest answer, because those map to Plus features (B2B company profiles, expansion stores, Checkout Extensibility at full depth). A single-storefront DTC store without B2B often does not need Plus, and we will say so. The platform recommendation is a written deliverable of our assessment, with the reasoning attached.

Yes, with Shopify Plus. BigCommerce customer groups with group-specific pricing map to Plus B2B company profiles and price lists; payment terms and B2B catalogs are configured per company. Standard Shopify can approximate simple cases with tags and a wholesale app, but real price-list B2B belongs on Plus. We migrate the group structure, rebuild the price lists, and test with your actual wholesale accounts before cutover.

Products with variants and options, the category tree (rebuilt as collections and navigation), customers with their group assignments, full order history with original order numbers preserved on the record, product reviews, gift certificate balances, discount codes, the BigCommerce blog, and standard pages. Customer passwords cannot move on any platform because they are stored irreversibly hashed; customers re-authenticate once on the new store, and we plan that messaging with you.

Almost always, and usually with more choice than you had. We inventory your installed apps in discovery and map each one to a Shopify equivalent, a native feature, or, rarely, a piece of custom work. The one category where we flag a genuine gap is faceted search: BigCommerce ships it natively on higher plans, and matching deep faceting on Shopify requires a paid search app. We price that into the recommendation instead of letting you discover it after launch.

Yes. All build and migration work happens in a private Shopify staging store while your BigCommerce store trades normally. Orders and customers that accrue during the build are re-synced in a final delta pass at cutover, and the switch itself is a DNS change measured in minutes. Zero downtime is the standard we have delivered on our largest migrations, and the parallel-run phase exists to make it boring.

A defined post-launch support period is part of every migration: daily monitoring of Search Console, analytics, checkout, and integration queues through the first weeks, plus fixes for anything the transition surfaces under real traffic. After that, most clients keep us on for ongoing development or CRO work, but the migration engagement stands on its own and ends with your team trained on the Online Store 2.0 editor.

The free assessment starts within days of your data access being granted, and it is the real answer to scheduling: it produces the risk map, timeline, and quote that let both sides commit to dates. Build slots depend on current bookings, which we will tell you plainly on the first call rather than promising a start date we cannot hold.

We rebuild its design, not its code. Stencil templates are Handlebars and Shopify themes are Liquid, so the theme is reimplemented as an Online Store 2.0 theme with sections, app blocks, and metafields. Your customers see the brand they know; your team gets a theme editor they can actually use. Custom Stencil features are inventoried one by one and rebuilt, replaced natively, or covered by an app, with each decision documented.

Not natively at the same depth, and we would rather tell you that here than after launch. Shopify's free Search & Discovery app covers filtering for many catalogs. Stores that depend on deep multi-attribute faceting add a search app (Boost, Searchanise, Algolia) at a monthly cost. During the assessment we check your analytics to see how customers actually use your current filters, then recommend the cheapest option that matches real behavior.
