Custom-built eCommerce platforms served a purpose when off-the-shelf solutions couldn't meet your needs. But maintaining legacy code, outdated frameworks, and proprietary databases is expensive and risky. Shopify's modern platform, combined with its API and app ecosystem, can replicate your custom functionality at a fraction of the ongoing cost.
Legacy frameworks (PHP 5, ASP.NET, ColdFusion, custom Java) lack modern security features, mobile optimization, and performance capabilities that today's shoppers expect.
Custom platforms require dedicated developers for every change. Bug fixes, security patches, server maintenance, and feature additions all require specialized knowledge of your unique codebase.
Unlike Shopify's 8,000+ apps, custom platforms have zero plug-and-play integrations. Every new feature — reviews, email marketing, analytics, loyalty programs — must be built from scratch.
Custom platforms often lack PCI compliance, regular security audits, and automated threat detection. Without a dedicated security team, your customer data is at constant risk.
When the original developers leave, so does the knowledge. Undocumented code, proprietary patterns, and custom database schemas make onboarding new developers costly and slow.
A structured, proven process that ensures zero data loss and minimal downtime. Every migration follows these carefully planned phases.
We reverse-engineer your custom platform — database schema, data relationships, API endpoints, business logic, and custom functionality. This creates a complete map of what needs to migrate.
Map your custom data structures to Shopify's data model. Custom fields become metafields, proprietary taxonomies become tags and collections, and relationships are preserved through Shopify's APIs.
Build extraction, transformation, and loading scripts tailored to your database. Handle data cleaning, normalization, deduplication, and format conversion for Shopify compatibility.
Set up your Shopify store with custom theme, apps, and integrations that replicate your custom platform's unique functionality. Build custom apps for features without existing solutions.
Import data in batches with automated validation at every step. Cross-reference source and destination databases to ensure 100% data accuracy and relationship integrity.
Reconnect ERP, CRM, warehouse, accounting, and marketing systems to Shopify using APIs and middleware. Replace custom integrations with Shopify-compatible connectors.
Map your custom URL structure (which could be anything) to Shopify URLs. Build comprehensive redirect rules that cover every possible URL pattern and query string combination.
Run both systems in parallel for a testing period. Once validated, perform a coordinated cutover with real-time data sync to ensure zero orders are lost during transition.
We migrate every piece of your Custom Platform store to Shopify, preserving data integrity and SEO value throughout the process.
Every product, variant, attribute, image, and relationship in your custom database migrated to Shopify. Custom product types and fields mapped to metafields and metaobjects.
Customer records from your proprietary database migrated with all profile data, addresses, purchase history, and custom attributes. Loyalty points and tiers preserved where possible.
Complete transactional history imported for business continuity, accounting records, and customer service. Payment records, fulfillment data, and return history included.
All content pages, blog posts, media assets, and document files migrated. Custom content types mapped to Shopify pages, metaobjects, or blog posts as appropriate.
Pricing rules, discount logic, tax calculations, shipping algorithms, and custom workflows replicated on Shopify using native features, Shopify Functions, or custom apps.
Every third-party integration — ERP, CRM, warehouse management, accounting, marketing automation — reconnected to your new Shopify store via APIs and middleware.
Yes. We've migrated stores from custom PHP, ASP.NET, Java, Python/Django, Ruby on Rails, ColdFusion, and even MS Access-based systems. If your data exists in a database, we can extract and migrate it to Shopify regardless of the technology stack.
We reverse-engineer your database schema to understand all tables, relationships, and custom fields. Then we build a custom ETL (Extract, Transform, Load) pipeline that maps your proprietary data structure to Shopify's data model using metafields, tags, and custom apps.
In most cases, yes. Shopify's native features, Shopify Functions, Flow automations, and custom apps can replicate complex pricing rules, discount logic, shipping calculations, and business workflows. We audit your custom logic and provide a detailed replication plan.
This is actually one of the most common scenarios we handle. We don't need your original developers — we reverse-engineer the database schema and codebase directly. Our team documents everything during the discovery phase to ensure a complete understanding.
We run automated validation checks at every stage: row counts, checksum verification, relationship integrity tests, and sample audits. After migration, we provide a detailed data accuracy report comparing source and destination for your review and approval.
Yes. We inventory all your integrations and either connect them to Shopify using existing connectors (most major ERPs and CRMs have Shopify integrations) or build custom middleware using Shopify's APIs. We ensure data flows identically to your current setup.
