Commerce Architecture & Engineering
Custom Commerce Platforms for Scaling Brands
MellowKraft designs and builds commerce infrastructure for companies that have outgrown Shopify.
The Growth Wall
Why Brands Outgrow Shopify
Every scaling brand hits the same inflection point. The platform that enabled your initial growth becomes the constraint on your next stage.
Platform Fees
Transaction fees and revenue-based pricing erode margins as you scale. What was affordable at $1M becomes a significant expense at $10M+.
App Dependency
Critical business logic distributed across dozens of third-party apps. Each one adds latency, cost, and a single point of failure.
Technical Constraints
Liquid templates, limited APIs, and rigid checkout flows prevent you from building the custom experiences your customers expect.
Data Fragmentation
Customer, order, and inventory data scattered across disconnected systems. No single source of truth for business intelligence.
The Economics
The Hidden Cost of Shopify at Scale
Platform fees, app subscriptions, and transaction costs compound as revenue grows. At scale, you're paying enterprise prices for a system you've outgrown.
* Estimates include platform fees, app subscriptions, transaction fees, and developer costs. Custom platform costs are annual infrastructure + maintenance.
