The goal is to build a secure, web-based application that uploads sales bills, tracks incoming payments, and then generates matching, automated accounting entries. Everything must run in the browser, with two-factor authentication protecting every user account. Core workflow • A user uploads one or many sales bills. • The system ingests payment data, shows real-time payment status against each bill, and automatically reconciles any matches it finds. • Once a bill and its payment align, the app posts the corresponding entry without manual intervention and flags anything that needs a human review. Essential deliverables 1. Responsive web interface for bill upload and payment status views 2. Matching engine that pairs bills to payments and creates the automated entries 3. Dashboard or report area to review matched and unmatched items 4. Two-factor authentication integrated into the sign-in flow 5. Deployment-ready codebase plus basic user & admin documentation You’re free to propose the tech stack you’re most comfortable with—just keep the process smooth, the interface clean, and the matching reliable.
