Project Overview
InvoiceFlow automates invoicing pipelines for professional service firms. It handles recurring billing schedules, sends reminders to clients automatically, and matches bank accounts to settle ledger balances.
Key Features & Scope
Automated PDF invoice generation and direct client emailing
Subscription billing portals powered by Stripe billing frameworks
Payment tracking widgets showing overdue logs and monthly revenue logs
Multi-currency conversion tables processing global client invoices
System Architecture
Built with Next.js App Router and Prisma. Stripe webhook subscriptions handle invoice states, updating tables inside a secure PostgreSQL cluster.
Biggest Challenge & Resolution
The Challenge
Professional service agencies struggled with manual PDF generation, late payments, and the overhead of matching bank transfers to outstanding bills across multiple currencies.
The Resolution
Architected a Next.js invoice engine integrated with Stripe Billing. It automatically compiles and emails cryptographic, tamper-proof PDF invoices, handles automated dunning email campaigns for late fees, and syncs account ledger balances in real-time, reducing late payments by 40%.
