What makes this service different
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.
Reverse-engineer first
We model your existing data, identify edge cases and rebuild on Shopify primitives.
Phased cutover
Catalog, then customers, then orders, then checkout each phase validated separately.
Integration replacement
Each custom integration is either retired, rebuilt as an app, or wired via webhooks.

Engineering Principles
Six principles we don’t negotiate on.
01
Performance is a feature
We ship with measurable budgets TTFB, LCP, INP enforced in CI. Storefront regressions don’t merge.
02
Theme apps over forks
We use Theme app extensions, sections, and metaobjects so your store stays upgrade-safe across every Shopify edition.
03
Observability before launch
Web Vitals, RUM, Shopify Functions logs and synthetic checks are configured before the first real customer.
04
Privacy as a baseline
GDPR/CCPA-aware data flows, consent-mode tagging and PII redaction at the edge by default, not by retrofit.
05
Documentation is delivery
Theme docs, component library, runbooks and onboarding ship with the code your team owns it from day one.
06
Senior, end-to-end
No first-line agents, no junior hand-offs. The architect who scopes your work is the one accountable for shipping it.
Engagement Models
Three ways to work with us.
Fixed scope
Project
End-to-end build against a clear scope, milestones, demos and a launch plan.
- Discovery + estimate
- 2-week sprints
- QA & launch support
Senior squad
Dedicated Squad
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
24×7
Managed Ops
Run, monitor, patch and optimise your store with SLAs measured in minutes not days.
- Theme + app patching
- 1-hour critical SLA
- Performance reviews
Replatforming, Reframed
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

Shopify 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.
