Rigid Theming
Storefront changes required developer time for even minor updates, slowing every marketing experiment.

Migrating Renadyl’s Ecommerce Ecosystem from BigCommerce to Shopify
Simplifi Commerce re-platformed a healthcare D2C brand from BigCommerce to Shopify Plus — preserving every order, customer, and subscription with zero downtime, while delivering faster performance and a higher-converting storefront.
The Client
Kibow Biotech & Renadyl
Kibow Biotech is the science-led manufacturer behind Renadyl, a clinically studied probiotic formulated to support kidney health. As a healthcare D2C brand, Renadyl serves a recurring customer base that depends on uninterrupted ordering, reliable subscriptions, and accurate fulfilment.
Their existing BigCommerce storefront had become a ceiling on growth — rigid theming, fragmented integrations, and a checkout that leaked conversions on mobile. Scaling the catalog, the subscription program, and marketing automation meant re-platforming onto a system built for compounding growth.
Simplifi Commerce led an audit-first migration to Shopify Plus: every product, customer, order, and active subscription was moved with zero data loss, and the storefront was rebuilt around a faster, higher-converting experience.
The Challenge
Scaling Beyond BigCommerce Limitations
The platform that launched the brand had become the thing holding it back. We mapped every constraint before touching a single line of the new build.
Conversion Leakage
A clunky multi-step checkout was dropping mobile shoppers before they reached payment.
Fragile Subscriptions
The recurring-order program ran on brittle integrations with limited control over billing logic.
Disconnected Stack
CRM, email, analytics, and fulfilment lived in silos with manual handoffs between them.
Slow Performance
Heavy page weight and slow load times hurt both SEO rankings and shopper experience.
Migration Risk
Years of customer, order, and subscription history could not afford even a single hour of downtime.
Why It’s Hard
Enterprise Ecommerce Migration Complexity
A platform migration is not a copy-paste. Each domain carries its own risk surface — and all of them had to land at once, cleanly.

- Order records with accurate status
- Tax, address, and payment metadata
Subscription Continuity

- Metadata & structured data retained
Integrations

- Analytics & pixels re-validated
- Fulfilment & ERP reconnected
Checkout & Payments

- Discount & tax logic rebuilt
- Mobile-first checkout flow
Go-Live Cutover

- Rollback plan on standby
How We Work
Strategic Ecommerce Migration Methodology
An audit-led process designed to remove risk at every stage — so the cutover is a non-event for the business and its customers.
Discovery & Audit
We map the full data model, integrations, and subscription logic, then document every dependency and redirect before the build begins.
Architecture & Build
We stand up the Shopify Plus environment, rebuild the storefront for speed and conversion, and re-wire the connected stack.
Data Migration
Products, customers, orders, and active subscriptions are migrated into staging with automated validation against the source.
QA & Validation
End-to-end testing of checkout, billing, redirects, and integrations — with a record-by-record reconciliation report.
Zero-Downtime Cutover
A planned DNS switch with a rehearsed rollback path takes the new store live without interrupting orders or subscriptions.
Optimize & Scale
Post-launch we monitor performance, tune conversion, and layer in automation to compound results over time.
