Options vs modifiers
Variant-generating options become Shopify variants; text, checkbox and file modifiers become line-item properties captured on the order.
Migration · BigCommerce → Shopify BigCommerce to Shopify,
BigCommerce to Shopify,
options and modifiers included.
BigCommerce and Shopify look similar on the surface, but they model products differently. Options that create variants and modifiers that only change the order line need different handling, and that is where most BigCommerce migrations go wrong.

Quick answer
What is the hardest part of a BigCommerce to Shopify migration?
Product options. BigCommerce separates variant options from modifiers such as engraving text or gift wrap. On Shopify, variant options become variants, while modifiers become line-item properties, product customiser apps or custom theme blocks, and each price adjustment has to be rebuilt deliberately.

Model differences we map
Price lists and customer groups
Group discounts and price lists move to Shopify discounts, or B2B catalogues on Plus for true wholesale pricing.
Brands
BigCommerce brand pages become automated collections driven by the product vendor field, keeping their URLs redirected.
Things to decide early
Faceted search
Filters are rebuilt with Shopify’s Search & Discovery filters on metafields, or a search app for very large catalogues.
Checkout scripts
Custom checkout JavaScript does not carry over; the same logic is rebuilt with checkout extensions or Functions on Plus.
Stencil theme
The design is rebuilt as an Online Store 2.0 theme — a chance to fix mobile speed rather than copy the old layout.
How your URLs will map
Each legacy pattern gets a 301 redirect to its Shopify equivalent, tested before the domain moves.

Merchants coming from BigCommerce often ran a separate accounting connector with its own subscription. The ZaadBooks Shopify connector ships with every ZaadBooks plan.

Questions BigCommerce:
BigCommerce:
common questions.
Can BigCommerce product modifiers work on Shopify?
Yes, rebuilt as line-item properties or with a product options app. Personalisation text, gift messages and uploads are captured on the order exactly as they were on BigCommerce.
Does Shopify have an equivalent of BigCommerce B2B Edition?
Shopify Plus includes B2B: company profiles, multiple buyers per company, catalogues with custom prices, quantity rules and payment terms, all in the same store as retail.
Will customer reviews come across from BigCommerce?
Yes. Reviews are exported and imported into a Shopify reviews app with their ratings and dates, and review schema is kept so star ratings can still appear in search.
How do you avoid 404 errors after migrating from BigCommerce?
We crawl the live store and pull URLs from Search Console and analytics, redirect every one with traffic or backlinks, and check crawl reports daily for two weeks after launch.
