Money & Paperwork
Rasid
An invoice studio where the document is the interface: typeset like print, with automatic math underneath.




The thinking
Invoices require both visual polish and accurate calculations. Rasid pairs a live-editing A4 preview with automated handling for numbering, tax calculations, and status tracking.
Context & Problem
Freelancers and small businesses need professional invoicing without complex enterprise software. Manual word processor templates introduce formatting glitches and calculation mistakes, while heavy SaaS tools are slow and expensive.
My Role
Product research, UI layout design, calculation logic implementation, and frontend application build.
The Approach
Created a split-screen workspace with a live print-ready A4 preview backed by automatic calculation engine.
Practical Outcome
Delivered a practical invoice studio that generates clear documents and tracks client payment status.
Built with
