Project Overview
Subscription-based e-commerce businesses depend on predictable recurring revenue from memberships, digital services, and repeat product deliveries. As subscriber volumes grow, managing billing cycles, payment collections, renewals, and exceptions manually leads to errors, revenue leakage, and poor customer experience.
We implemented a Subscription Billing & Payment Automation System using AI-driven workflow automation to orchestrate the entire subscription lifecycle from recurring invoice generation to payment retries and reconciliation. The solution unified billing and payment workflows into a single, intelligent automation layer.
Business Challenges
The e-commerce client faced recurring operational challenges:
- Manual handling of recurring billing cycles
- Errors in subscription renewals and plan changes
- Failed payments and delayed collections
- Poor visibility into active, paused, and cancelled subscriptions
- High volume of billing-related support tickets
- Difficulty scaling billing operations with subscriber growth
These issues directly impacted revenue stability and customer trust.
What We Delivered
We delivered an end-to-end subscription billing and payment automation solution:
Key deliverables include:
- Automated recurring billing workflows
- Subscription lifecycle management (activation, renewal, cancellation)
- Event-driven payment orchestration
- Intelligent retry logic for failed payments
- Automated invoice generation and notifications
- Integration with CRM, payment gateways, and accounting systems
- Centralized dashboards for subscription and revenue visibility
The solution eliminated manual intervention while maintaining financial accuracy.
Proposed Architecture & Design
The system architecture was designed for reliability and scale:
- Workflow automation engine orchestrating billing and payment events
- Event-driven triggers for renewals, retries, and cancellations
- Secure integration with payment gateways
- Rule-based logic for proration, discounts, and plan changes
