Overview
Chitza V2 represents the evolution of a financial document platform built to digitize, structure, and manage transaction proofs like invoices, receipts, and vouchers for individuals and businesses alike. While the original platform helped users go paperless, its architecture, performance, and UX needed a significant upgrade.
That’s where we at DEIENAMI stepped in.
The client engaged us to engineer and deliver the next generation of Chitza—a cleaner, faster, scalable version of the product that could meet enterprise-grade expectations without compromising on accessibility for everyday users.
What the Client Needed from the V2 Revamp
- Upgrade the tech stack to handle increased user load and real-time sync
- Overhaul the UX/UI across web and mobile to improve adoption and retention
- Introduce modular APIs for future integrations (e.g. GST portals, ERPs)
- Enable offline support via PWA and mobile-first interfaces
- Ensure data encryption, secure sharing, and privacy compliance
- Build a sustainable codebase that can scale with future roadmap items
