Move from any custom commerce stack to Shopify, safely.
Custom Platform Migration to Shopify is for merchants on bespoke, legacy or in-house commerce platforms. We reverse-engineer your data model, define a Shopify equivalent and execute a phased cutover that preserves history, SEO and integrations.
We model your existing data, identify edge cases and rebuild on Shopify primitives.
Catalog, then customers, then orders, then checkout each phase validated separately.
Each custom integration is either retired, rebuilt as an app, or wired via webhooks.
Move from any custom commerce stack to Shopify, safely.

The Shopify tools we ship with every single sprint.
A senior, opinionated stack chosen for raw performance, observability and long-term maintainability.
Six principles we don’t negotiate on.
We ship with measurable budgets TTFB, LCP, INP enforced in CI. Storefront regressions don’t merge.
We use Theme app extensions, sections, and metaobjects so your store stays upgrade-safe across every Shopify edition.
Web Vitals, RUM, Shopify Functions logs and synthetic checks are configured before the first real customer.
GDPR/CCPA-aware data flows, consent-mode tagging and PII redaction at the edge by default, not by retrofit.
Theme docs, component library, runbooks and onboarding ship with the code your team owns it from day one.
No first-line agents, no junior hand-offs. The architect who scopes your work is the one accountable for shipping it.
Three ways to work with us.
End-to-end build against a clear scope, milestones, demos and a launch plan.
- Discovery + estimate
- 2-week sprints
- QA & launch support
A senior pod of Shopify architects and developers integrated with your team flexible roadmap, weekly demos.
- 3–6 person Shopify pod
- Weekly cadence
- Dedicated tech lead
Run, monitor, patch and optimise your store with SLAs measured in minutes not days.
- Theme + app patching
- 1-hour critical SLA
- Performance reviews
From legacy to Shopify choreographed, not chaotic.
The orbiting shards are data domains: customers, catalog, orders, content. Each lands cleanly with mapped, validated rows.
- Dual-write cutover plan
- Row-level reconciliation
- 1:1 SEO redirect map
- Rollback rehearsals

ExploreShopify questions, answered.
We don’t have great documentation can you still migrate us? +
Yes. Most of our custom-platform clients arrive without docs. We profile the database directly and rebuild documentation as part of the engagement.
How do you avoid downtime? +
Dual-write cutover and DNS pre-warming let us swap with zero downtime. We rehearse the full sequence on staging twice before production.
What if our legacy platform doesn’t expose an API? +
We extract via direct database reads, file dumps or scraping where compliant then validate every row against checksums before importing into Shopify.
Can we keep our existing CMS? +
Yes we can pair Shopify with Sanity, Storyblok, Contentful or Strapi for content, and use Shopify only for commerce.
