You’re on BigCommerce. You watched the 2026 pricing announcement. You ran the math. The migration to Shopify pays back inside 18 months for your GMV band. The remaining question is who runs the transfer. Below are the agencies actually built for mid-market BC-to-Shopify work in 2026.
A BigCommerce-to-Shopify transfer has three high-risk surfaces: data fidelity, SEO continuity, and app-stack translation. Get one of them wrong and the transfer drags on for months in stabilization. The agencies below all run transfer processes that minimize each risk.
How we evaluated BC-to-Shopify transfer specialists
- Product, customer, and order data transfer documented in scope
- URL redirect mapping including parametrized URLs
- App stack translation with BC-to-Shopify equivalents identified pre-launch
- In-house engineering with no offshore subcontracting
- Post-launch monitoring built into the engagement
1. Netalico
Founded in 2017 and headquartered in Miami, Florida, Netalico has built its practice around mid-market DTC brands ($2M-$50M GMV) on Shopify Plus.
The team handles the full BigCommerce-to-Shopify transfer: data export with fidelity checks, 301 redirect map covering products, categories, parametrized URLs, and CMS pages, app stack translation with documented equivalents, theme rebuild, soft launch, and 90-day weekly rank monitoring. The same team that scopes the transfer is the team that delivers it.
Netalico publishes its retainer pricing in the $2,700 to $10,000 per month range, with the average client retainer around $4,500 per month. Project work runs $25,000 to $250,000+ depending on scope. The team that builds the new store stays on retainer afterward, which is how the transfer BigCommerce to Shopify practice continues to deliver outcomes for the next two years rather than ending at launch day.

Frequently Asked Questions
How do I transfer my BigCommerce store to Shopify?
The standard transfer sequence: export BC product/customer/order data with fidelity checks, build a 301 redirect map for every old URL, translate the app stack to Shopify equivalents, rebuild the theme, run a soft launch with QA, then monitor rankings for 90 days. Mid-market transfers ($2M-$50M GMV) take 8-16 weeks.
Can I migrate BigCommerce data to Shopify automatically?
Partially. Tools like Cart2Cart can move basic product, customer, and order data automatically, but the work that breaks migrations (parametrized URL redirects, app stack translation, custom field mapping, B2B workflow translation) almost always needs an agency. The automated tools handle maybe 60% of a mid-market transfer.
What gets transferred during a BigCommerce to Shopify migration?
Products (with variants, images, descriptions, SEO fields), customers (with order history and saved addresses), orders (with status and line items), CMS pages and blog posts, and 301 redirects for every old URL. Some BC-specific configurations (custom fields, certain extension data) require manual translation.
What does it cost to transfer from BigCommerce to Shopify?
Mid-market BC-to-Shopify transfers run $25,000-$80,000 in agency fees. Enterprise transfers with B2B or multi-store complexity run $80,000-$250,000+. Common add-ons: extra month of stabilization support, custom app translation, theme design from scratch.
Do I lose customer accounts when I transfer?
No. Customer records (email, name, address, order history) transfer cleanly. Customers will need to reset their passwords on first login to Shopify, which is standard across platform migrations. A BigCommerce to Shopify migration team usually handles the customer-comms around the password reset.
Will the transfer affect my existing SEO rankings?
Not if the redirect map is complete. The most common SEO loss during BC transfers happens with parametrized URLs (search results, sort filters) that get missed. A reputable agency monitors Google Search Console weekly for 90 days post-launch to catch any rankings that drift.
How long does a typical BigCommerce transfer take?
Mid-market BC-to-Shopify transfers complete in 8-16 weeks. The variable is usually the data audit and app translation, not the theme rebuild. Enterprise transfers with B2B, multi-store, or headless scope stretch to 16-24 weeks.
Bottom line
If you’re transferring from BigCommerce to Shopify in 2026, the agency shortlist is short.
