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.
