Let's answer this one directly, because most "migration services" pages dodge it: most businesses spend somewhere between $500 and $15,000+ on a WooCommerce to Shopify migration, and the honest answer to "what will mine cost" depends far less on SKU count than most merchants assume. Two stores with the same number of products can land in completely different budget tiers based on complexity alone.
To give you a realistic starting point rather than a single misleading number: a standard catalog store, up to around 1,000 SKUs, a standard theme, native Shopify features, and a straightforward redirect map, typically lands in the low-to-mid four figures, often $1,500–$5,000, at roughly 40–60 engineering hours. A mid-market custom store, 1,000 to 10,000 SKUs, custom metafield mapping, multi-currency via Shopify Markets, and app-parity integrations, typically runs $5,000–$20,000, around 80–120 hours. An enterprise ecosystem migration, 10,000+ SKUs, multi-warehouse IMS/WMS sync, custom ERP/CRM integrations, headless builds, or B2B/wholesale logic, starts at $20,000+ and can run 200+ hours.
(These ranges reflect what's currently being quoted across the market for comparable scope, confirm them against your actual rate card and delivery cost before publishing. Publishing a real, defensible range is what separates a page that ranks from one that doesn't, vague "contact us for pricing" language is exactly what the top-ranking cost guides in this space have already replaced.)
On top of the migration fee itself, budget for what changes after launch: a premium Shopify theme runs roughly $180–$350 if you're not going custom, and each WooCommerce plugin you depend on today needs a Shopify app replacement commonly $10–$100 per app per month, which adds up fast if you're running five or more. Factor this into the total cost of ownership conversation with clients, not just the one-time migration invoice.
Beyond SKU count, the cost drivers that come up most often are:
- Complex variants, bundles, or subscription products
- Plugin-dependent checkout logic
- Custom WooCommerce fields that must map into Shopify metafields
- A heavy SEO footprint requiring large redirect matrices
- Integration scope across ERP, WMS, CRM, email automation, and supplier feeds
- Multi-currency or multi-region requirements
- Analytics complexity where full event-tracking parity is required
This is exactly why two stores with identical SKU counts can land in completely different budget tiers.
