Not sure where to start?

Find the platform challenge or commercial goal you’re facing today, and the right migration approach becomes obvious.

Most mid-market retailers begin with our Consult & Configure setup for rapid time to market. Brands with complex ERP/EPOS integrations, high SKU counts or bespoke design requirements move into a Standard or Advanced Enterprise Build.

Partnering with StudioForty9 to migrate our ecommerce platform to Shopify Plus was a critical decision for Intersport Elverys.

I speak for our team as a whole when I say we could not recommend StudioForty9 enough! The whole process of was pleasant, efficient, and the team took a very hands on and in-depth approach in evaluating all of our wants & needs as a business.

Frequently Asked Questions

How long does an enterprise ecommerce migration typically take?

Our average enterprise migration timeline is 4 to 6 months from initial discovery to live cutover. The exact duration depends on project scope, custom UX requirements and the complexity of back-end ERP/EPOS integrations. Every project begins with an intensive scoping phase ("Measure Twice, Cut Once") to establish a firm, realistic timeline and eliminate unexpected delays.

Will migrating to a new platform harm our SEO rankings, traffic or customer order history?

No. Safeguarding your digital assets is a core priority. We execute meticulous 301 URL redirect mapping to preserve organic search rankings and domain authority. We also migrate historical product data, customer accounts (using secure, passwordless re-authentication) and complete order histories so your customers experience zero disruption on launch day.

How do you handle complex ERP, EPOS and inventory integrations during a migration?

We use Orchestra, our proprietary integration middleware, as the central nervous system connecting your storefront to legacy back-end systems (such as Meridian, Trader, SAP or WaveOMS). Orchestra manages bi-directional inventory syncs, 15-minute delta updates, price file reconciliations and complex order pass-backs for kits and bundles without slowing down front-end page speeds.

How do you prevent project scope creep and internal testing fatigue for our team?

We employ a Dual-PM Governance Model that splits build execution management from User Acceptance Testing (UAT). Our team guides your internal stakeholders through structured UAT phases, providing pre-written test scripts and dedicated staging environments. We also enforce strict data freezes outside peak trading windows to ensure launch readiness without overwhelming your staff.

How are migration costs structured, and which build tier is right for us?

We offer three distinct migration pathways tailored to commercial goals and technical complexity:

  • Consult & Configure (C&C): Accelerated setup using best-practice theme frameworks for rapid market entry.
  • Standard Enterprise Build: Custom UX/UI design, full historical data transfer and single primary ERP/EPOS integration.
  • Advanced Custom Build: Bespoke design systems, complex multi-system middleware architecture, custom bundling and specialised business logic.
