Payment & Billing Automation

Automated billing cycles, invoice generation, payment webhooks, and finance workflow automation.

The Payment & Billing Automation system handles subscription billing, invoice generation, payment verification, and webhook-based updates without manual work. It supports recurring payments, failed payment retries, auto-generated PDFs, and automated email notifications. The system ensures accurate, error-free, and timely billing for all customers.

Payment & Billing Automation

The Challenge

The client manually created invoices, tracked payments on spreadsheets, and updated customer status by hand. This led to missed due dates, double entries, and billing inconsistencies.

They needed an automated system that connects payment gateways, billing logic, and CRM updates with zero human involvement.

Solution

We created a fully automated billing engine with PDF invoice generation, GST calculations, email notifications, and real-time payment status updates via webhooks. Failed payments trigger retry cycles, and successful payments automatically update user validity.

An admin dashboard shows transaction history, invoices, and status logs. Secure API handling ensures accurate communication with the payment gateway.
