ProBill: From MVP to a Full Billing SaaS Platform

The challenge

Small businesses and agencies were losing hours every week to manual invoicing — generating invoices in spreadsheets, chasing overdue payments by email, and reconciling multi-currency transactions by hand. ProBill set out to replace that entire workflow with one clean dashboard.

What we built

TechieBall built ProBill as a full billing and invoice management SaaS platform, covering the entire payment lifecycle:

• Automated invoice generation and delivery with custom templates
• Real-time payment tracking across paid, pending, and overdue states
• Multi-currency support with automatic tax handling for global clients
• Smart, automated payment reminders that removed manual follow-up entirely
• Revenue analytics and cash-flow dashboards
• Role-based access control and encrypted cloud storage

Technical approach

The application is built on React for a fast, responsive front end, a Node.js API layer, and PostgreSQL as the system of record for financial data — chosen specifically for the relational integrity billing data demands. The platform is deployed on cloud infrastructure with automated backups and encrypted storage, and integrates with common accounting tools and payment gateways.

The result

ProBill now processes over 1,240 invoices and tracks ₹4.2M in payments for 340 active clients, with a 98% on-time payment rate — a direct result of the automated reminder system replacing manual chasing.

"The ProBill app TechieBall built transformed how we handle invoicing. The UI is clean, fast, and our team adopted it instantly. Login to report generation in seconds — that's the kind of efficiency we needed."
