ChaChingify
The all-in-one profit dashboard for Printify × Etsy sellers. Auto-match products, track margins in real-time, and never wonder about your profits again.
The Problem: Flying Blind on Margins
Print-on-demand is a booming industry — but the tools haven't kept up. Sellers using Printify for production and Etsy for sales were stuck in a frustrating gap: Printify knows your costs but not your prices. Etsy knows your prices but not your costs. No tool connected the two.
The result? Sellers managing hundreds of products were making pricing decisions based on gut feeling, not data. They'd spend hours every week cross-referencing spreadsheets, manually matching products between platforms, and still not knowing their true profitability.
Our client — a multi-brand POD seller managing over 500 products across several Etsy storefronts — came to us with a clear pain point: "I literally don't know which of my products are making money and which are losing money."
That's not a minor inconvenience. That's a business flying blind.
What We Built
ChaChingify is a full SaaS platform that connects Printify and Etsy into a single, unified profit dashboard. We designed and built it from the ground up in under 6 weeks using AI-accelerated development.
Unified Product Dashboard
The core experience is a single searchable, sortable table showing every product with its production cost (from Printify), selling price (from Etsy), and calculated profit margin — all in one view. No more tab-switching, no more spreadsheets.
Intelligent Auto-Matching Engine
We built a smart matching algorithm that normalizes product titles from both platforms — stripping special characters, handling variations in spacing and casing — then finds matches based on title similarity. Products with a 60%+ word overlap are automatically linked.
Real-Time Profit Analytics
Every matched product shows its exact margin. The dashboard includes category-level breakdowns, showing sellers which product types are most profitable.
Enterprise-Grade Security
We implemented AES-256-GCM encryption for all stored tokens, OAuth 2.0 PKCE flow for Etsy authentication, and zero plain-text token storage.
Multi-Shop Architecture
We designed the data model from day one to support multiple Printify and Etsy shops under a single account, with separate tracking and combined analytics.
Tech Stack
- Next.js with App Router for the frontend and server-side rendering
- TypeScript end-to-end for type safety across the entire codebase
- tRPC for end-to-end typesafe API calls between client and server
- TanStack Query for intelligent data fetching, caching, and real-time updates
- PostgreSQL for relational data storage with complex product matching queries
- Tailwind CSS for a responsive, polished UI built at speed
- OAuth 2.0 PKCE and AES-256-GCM for authentication and encryption
- Vercel for deployment with edge functions and global CDN
The Outcome
ChaChingify launched with a freemium pricing model — free for up to 50 products, $19/month for unlimited products with advanced analytics, and $49/month for multi-shop teams.
The platform processes product matching and margin calculations across catalogs of hundreds of items in seconds, turning what used to be hours of manual spreadsheet work into a one-click operation.
Built and shipped from concept to production in under 6 weeks using AI-accelerated development.
