BigCommerce to Shopify migration: replatforming without SEO loss

BigCommerce is a mature, hosted platform. The question behind a move is not whether your store works, but whether the platform fits your next step: wholesale, a physical store, new markets or more integrations.

Since 1 June 2026, BigCommerce's new pricing model is part of that equation as well. These are the points we put side by side in the audit:

• 01Costs that scale with you: Core and Growth move up a plan automatically once your trailing twelve-month sales pass $30,000 or $100,000. Scale charges 0.9% on sales above $33,333 a month.
• 02Payment providers: on Core, Growth and Scale, BigCommerce charges 0.6% to 2.0% on orders processed by a provider outside its own list. Shopify also charges a fee outside Shopify Payments (0.2% to 2%), so we compare both on your payment mix.
• 03B2B: since April 2026, B2B is included in every Shopify plan from Basic up, with up to three catalogues and unlimited catalogues on Plus. On BigCommerce, price lists are reserved for Performance and B2B Edition is a separate product priced on request.
• 04Ecosystem: the Shopify App Store lists more than 16,000 apps, the BigCommerce marketplace more than 1,200.
• 05Retail and international: Shopify has its own point of sale and Markets on every plan. BigCommerce relies on POS integrations and charges for extra storefronts as an add-on.

Both platforms are hosted and PCI DSS Level 1 certified, so hosting and platform security sit with the vendor. The differences lie in the data model, the checkout and the way each platform grows with you.

Where BigCommerce is stronger, we say so. Its checkout is open source, and products with more than three variant options do not map one to one onto Shopify. We record those points in the audit, together with the solution.

As a starting point: from 15,000 euros for a premium theme build with data migration and redirects, from 25,000 euros for custom work and from 35,000 euros for a replatforming to Shopify Plus. Where your BigCommerce migration lands depends mainly on these factors:

• 01Catalogue: the number of products, variants and modifiers, and how many custom fields need to move as metafields. Products with more than three variant options need extra modelling.
• 02Apps: for each BigCommerce app we choose a Shopify feature, an app or custom work. Every app is a decision and a test.
• 03Integrations: ERP, accounting, PIM, fulfilment and marketplaces that need to be reconnected.
• 04B2B: customer groups, price lists and B2B Edition features such as quotes and invoices translate into companies, catalogues, payment terms and draft orders in Shopify.
• 05Storefronts: multiple BigCommerce storefronts become markets within one store or, on Plus, separate expansion stores.
• 06Design: a Stencil theme cannot be carried over, so your design becomes a new Shopify theme.

After the audit these factors are concrete, and the quote is based on your own store, not on an average.

Most of the risk sits not in the export but in the translation to Shopify. These are the six points we deal with up front:

• 01URLs and redirects: BigCommerce lets each store choose its own URL format, including category or SKU in the path, and creates 301s itself when names change. We carry those redirects over, so every old URL reaches its new address in a single hop. URLs with filter parameters are handled separately, because Shopify redirects do not always work on them.
• 02Options and modifiers: Shopify supports 2,048 variants but at most three options per product. We restructure products with more variant options, on Plus possibly with Combined Listings. Modifiers become input fields that travel with the order; for modifiers that add a surcharge we choose a solution per product.
• 03Customer groups: group discounts become discounts for a customer segment. Groups with their own prices or restricted products become B2B companies with a catalogue, per B2B market or, on Plus, assigned directly per company.
• 04Passwords: BigCommerce does not export passwords and Shopify does not import them. With Shopify's customer accounts, customers sign in with a one-time code by email, without a password. We announce the new way of signing in ahead of launch.
• 05Gift certificates: Shopify accepts only letters and numbers in a gift card code. If a BigCommerce code contains dashes, the balance moves to an adjusted code and we inform the holder.
• 06Tracking: scripts from BigCommerce's Script Manager, including those on checkout and order confirmation, do not move across on their own. On Shopify they run as app or custom pixels, and we test every conversion before the DNS switch.
