Our BigCommerce to Shopify Migration Process

Moving from BigCommerce to Shopify shouldn’t feel uncertain. We use a structured, repeatable process refined across real migrations — with AI applied where it genuinely helps (surfacing data inconsistencies, speeding up mapping, flagging structural gaps), and every stage reviewed, tested, and validated by people before launch.
Reviewing BigCommerce store architecture, apps, and data before Shopify migration

Step 1 — BigCommerce Architecture Review

We start by going through how your store actually works today — the apps you're running, your product and variant data, the URL structure, and how SEO is set up — to see how it all fits together. AI helps us spot gaps in that faster, but a person still reviews each piece, so nothing gets missed before the move.

Step 2 — Shopify Store Framework & Setup

Many brands treat the move as the moment to improve the storefront. We’ll either build a fresh, faster, mobile-first design or recreate your existing look inside Shopify — your call. Either way, the foundation is built to perform.

Step 3 — Functionality Rebuild & Feature Alignment

In a separate development store (via our Shopify Partner account), we rebuild the features your business relies on — filters, variant logic, pricing rules, B2B/wholesale, and connected tools. Shipping, tax, and payment settings are configured ahead of time so the store is ready to operate before any data moves.

Step 4 — Data Transfer & Validation

Once the store is built, the data comes across. We run it through migration tools we trust — LitExtension or Cart2Cart for standard catalogs, Matrixify when a store is large or complex and needs tighter control over how fields map. These connect straight to BigCommerce and bring products, customer accounts, and past orders into Shopify. After the transfer, we go through it by hand in Shopify — products, collections, orders, customers — to confirm everything landed where it should.

Step 5 — Protecting Rankings During Migration

URLs change when you replatform. Before launch, we pull every existing BigCommerce URL, map each to its closest Shopify page with a 301 redirect, and carry over titles, descriptions, alt text, and schema so the store keeps the signals search engines already trust.

Step 6 — Launch & Communication Strategy

Going live is handled step by step: a reference copy is created, a final QA pass confirms everything works, then DNS records are updated to point the domain at Shopify. Because BigCommerce and Shopify encrypt passwords differently, customers reset passwords on first login — so we prepare customer comms in advance so the transition is smooth.

How Much Does a BigCommerce to Shopify Migration Cost?

Every BigCommerce store is built a little differently, so cost tracks what actually has to be rebuilt. A standard catalog with a few apps is straightforward; a store running custom pricing, B2B rules, detailed SEO, and third-party integrations takes more work to recreate in Shopify. As a rough guide, projects fall into three bands:

Mid-size store

Mid-size store

(500–5,000 SKUs, some custom features)

6–9 weeks

A larger catalog with custom features, B2B pricing, or integrations.

Large / complex store

Large / complex store

(5,000+ SKUs, ERP/CRM, custom build)

12–16+ weeks

Heavy customization, wholesale/B2B, or many connected systems.

The cleanest way to know your number is a scoped estimate against your real store. Ballpark it with our Shopify cost calculator, see how pricing breaks down in our migration cost guide, or request a free estimate, and we'll size it for you.

Migrations We've Handled — And What Happened After

A migration is only a success if the store performs after the move. Here's what happened to two businesses we moved onto Shopify — one enterprise-scale build, one high-volume catalog.

Featured Case Study

Soccer City

Vancouver, BC — Specialty sports retailer (direct-to-consumer + team stores)
Migration to Shopify 4,000+ SKUs 100+ collections 5 weeks Zero downtime

A 4,000-SKU catalog migrated to Shopify in five weeks — with rankings and uptime fully intact

Soccer City had outgrown their existing ecommerce platform after years of catalog growth: 4,000+ SKUs, 100+ collections, and a dual-audience model — direct shoppers plus a network of team stores — that the old platform couldn't support cleanly. With the spring season and the FIFA World Cup approaching, we had a hard five-week launch window. We rebuilt the operational foundation in Shopify: catalog architecture, AI-powered search across the full range, and a custom shared-inventory solution for the team-store network — migrating every product, collection, and order record while the live store kept trading the whole time.

Caviar Centre

Gourmet food & fine delicacies — high-value, perishable catalog

Caviar Centre needed a store that matched the premium nature of the product — cleaner merchandising, a faster and more trustworthy checkout, and a platform that could handle a high-value, perishable range without friction. We rebuilt it natively in Shopify, carried every product and customer record across without loss, and mapped a full set of 301 redirects so the search visibility the brand had earned stayed intact through the move.

FAQ

BigCommerce to Shopify Migration FAQ

When a business considers moving from BigCommerce to Shopify, the same questions come up. Below are straightforward answers based on real migration experience.

How long does a BigCommerce to Shopify migration take?

+

Most projects land in a 4-to-8-week window, with store size and complexity deciding where you fall. A small, mostly standard catalog moves quickly. Larger stores — lots of SKUs, complex variants, B2B pricing, or heavy SEO — need more planning and testing. The work runs through a few stages: auditing the BigCommerce setup, rebuilding features in Shopify, moving and checking the data, setting up redirects, and testing checkout before you go live.

How much does a BigCommerce to Shopify migration cost?

+

There's no fixed figure, because no two BigCommerce stores are built the same. Cost tracks how customized yours is — a standard catalog with a few apps is simple, while custom pricing, B2B rules, detailed SEO setups, and third-party integrations all add work to rebuild in Shopify. The reliable way to get a real number is a scoped estimate against your actual store, and we'll put one together for you.

Will I lose SEO rankings or data when migrating from BigCommerce?

+

Not if it’s done carefully. Drops usually happen when old URLs stop working after the move. We review your existing BigCommerce URLs and 301-redirect each to its closest Shopify page, and we carry over titles, meta descriptions, alt text, and schema so the store keeps its existing search signals.

Can I migrate my BigCommerce B2B / wholesale setup?

+

Yes, but it doesn’t copy over automatically. BigCommerce B2B price lists and customer groups map to Shopify’s B2B features (on Plus) or to apps on standard plans. We assess your setup and rebuild the pricing logic so wholesale customers keep their experience after launch.

Do customer passwords transfer during migration?

+

No. BigCommerce and Shopify encrypt passwords differently, and Shopify won't import encrypted passwords from another platform. Everything else — customer accounts, order history, account details — still migrates; it's only the password that resets. Customers set a new one the first time they log in, and we help you send a quick heads-up beforehand so no one's caught off guard.

Can I keep my existing domain when moving to Shopify?

+

Yes. Once the Shopify store is ready, we point your domain's DNS records at it. The address stays the same — customers just land on a faster, cleaner store.

Trusted Migration Partners

Every migration runs on tools we've tested and trust. For the move itself, that means LitExtension, Cart2Cart, and Matrixify for the heavier BigCommerce catalogs, alongside Shopify's native import. To protect search, Read more we rely on Easy Redirects, Ahrefs, and Google Search Console to map and monitor URLs. After launch, the store runs on vetted apps for email, reviews, search, subscriptions, and analytics — each one earning its place, not chosen because it's popular. Read Less
