If you’re under $400k/year and BigCommerce works, stay, if you’re scaling and the platform is starting to feel like a ceiling, the move is worth running the numbers on.
Where the work actually is
The data migration is straightforward, BigCommerce exports cleanly. The leverage in the project is in (a) re-mapping custom fields and modifiers into Shopify’s metafield/variant model so your theme reads them correctly, and (b) rebuilding the front-end on Online Store 2.0 instead of porting the Stencil layout one-for-one.
What we don’t do
- We don’t migrate stores actively earning under $200k/year unless there’s a B2B or international expansion driver, the maths usually doesn’t justify it.
- We don’t carry over Stencil-era theme code. The architecture differences are too deep to retrofit cleanly.
- We don’t promise zero downtime; we promise zero customer-facing downtime. There’s a brief DNS propagation window where some visitors hit either side.
