Custom Platform to Shopify Migration Services

Your development team built your platform for a reason, and now that reason may be costing more to maintain than it saves. Custom platform migrations to Shopify average 20-32 weeks because there is no export tool, no documentation, and no standard equivalent for anything custom-built.

weeks for custom platform discovery before any scope is agreed

Custom platform discovery is the most important investment in the migration. Shero will not quote a custom platform migration without completing a discovery sprint. Timeline and cost are always based on discovery findings.

20-32

weeks for a typical custom platform migration

Custom platform migrations are the longest in Shero's practice, second only to SFCC. The wide range reflects the variability of what custom platforms contain. The actual timeline is provided after discovery.

years in eCommerce

Shero has migrated brands of all sizes from custom-built platforms to Shopify. The discovery-first methodology was built from early experiences with custom platforms where assumptions about scope produced inaccurate timelines.

98%

client retention

Most Shero custom platform migration clients continue on a Shopify support retainer. The platform transition eliminates the custom codebase but ongoing Shopify development continues. The migration services hub covers all platform migration types.

Working with Shero has been an outstanding experience. Their team is highly skilled and easy to work with.

What a custom platform to Shopify migration covers

Custom-built ecommerce platforms are built for specific business requirements that off-the-shelf platforms could not meet at the time. They carry deep business logic, custom data models, proprietary integrations, and no migration tooling. Data comes out via API or direct database export. Shero migrates brands from custom-built platforms to Shopify or Shopify Plus. The engagement starts with a discovery sprint to document every piece of custom functionality before any scope is agreed. Timeline and cost are always based on the discovery findings, not assumptions about what a custom platform typically contains.

  • Custom platform discovery and architecture audit
  • Data extraction via API or database export
  • Business logic gap analysis and Shopify mapping
  • Custom functionality rebuild in Shopify
  • ERP and third-party integration rebuilds
  • URL mapping and SEO protection

Why brands on custom platforms choose Shero for migration to Shopify

Custom platform migrations fail when they are scoped without discovery. Agencies that quote based on assumptions about what a custom platform contains discover the real complexity after the build has started. The discovery sprint is the most important investment in any custom platform migration.

01

Discovery is the entire project, not a project phase

Custom platforms have no documentation, no migration tooling, and no standard data model. The discovery sprint maps every database table, every piece of business logic, and every integration endpoint before scope is agreed. Shero will not quote a custom platform migration without completing discovery first. Any agency that does is guessing.

02

Data extraction requires API engineering or direct database access

Custom platforms have no CSV export and no migration tool compatibility. Data comes out via API or direct database export. Shero maps the custom data model to Shopify's product and customer model during discovery so the extraction is clean and the import is validated before any redirect is activated.

03

Business logic embedded in custom code has no Shopify equivalent

Custom pricing rules, custom checkout flows, custom loyalty systems, and custom order management logic all need to be mapped to Shopify equivalents before the build starts. Some map to Shopify-native features. Some map to App Store apps. Some require custom Shopify development. Shero documents every decision and cost before any code is written.

04

Custom platform integrations are built against a proprietary API that Shopify does not support

ERP, OMS, and third-party integrations built for a custom platform use the custom platform's API. Every integration must be rebuilt for Shopify's API. This is the longest lead-time workstream in any custom migration. Shero scopes every integration in the discovery sprint. The Shopify ERP integration page covers the rebuild scope for common enterprise ERP systems.

05

SEO is more complex on custom platforms because URL structures are fully proprietary

Custom platforms use completely proprietary URL structures. Shero maps every URL pattern in discovery and builds a complete redirect map before any DNS change. Custom platforms also often have non-standard sitemap configurations and meta structures that need explicit mapping before the Shopify site goes live.

06

Custom platform migrations take longer than any other platform type except SFCC

A custom platform migration takes 20-32 weeks depending on complexity. The wide range is because discovery determines the actual scope. Shero provides the timeline after discovery, not before. The migration services hub covers how custom platform migrations compare to standard platform migrations in scope and timeline.

How Shero migrates from a custom platform to Shopify

01

Discovery sprint

Spend 2-3 weeks documenting every database table, business logic rule, integration endpoint, and URL pattern before any scope is agreed or timeline is committed.

02

Gap analysis and architecture decisions

Map every piece of custom functionality to a Shopify equivalent: native feature, App Store app, or custom build. Every gap that requires custom development is priced separately before build begins.

03

Data extraction and mapping

Extract data via API or direct database export. Map the custom data model to Shopify's product and customer model. Validate data integrity before any product goes live.

04

Custom functionality and integration build

Build custom Shopify functionality for logic that has no Shopify equivalent. Rebuild ERP and third-party integrations against Shopify's API from specification.

05

URL mapping and SEO setup

Map every custom URL pattern to a Shopify URL. Verify the complete redirect set before go-live. Monitor organic traffic for 90 days post-launch.

06

Go-live and stabilisation

Run the pre-launch checklist. Monitor integration health, data integrity, and checkout conversion daily. Custom platform migrations require the longest stabilisation period of any migration type.
