SaaS Subscription & Billing System Development

Revenue leakage from failed payments, manual invoicing, and rigid billing models costs SaaS companies millions annually. We build custom subscription and billing systems that integrate directly with Stripe and Razorpay, support usage-based and metered billing, handle proration and plan changes gracefully, and recover failed payments automatically through intelligent dunning sequences.

Subscription & Billing Features We Build

Complete billing infrastructure for SaaS products -- from payment processing to revenue analytics

Stripe & Razorpay Integration

Deep integration with Stripe Billing and Razorpay Subscriptions APIs including customer portal, payment methods management, webhook event processing, and automatic reconciliation. Support for cards, UPI, net banking, wallets, and SEPA Direct Debit depending on region.

Usage-Based & Metered Billing

Track and bill based on actual resource consumption -- API calls, storage, compute hours, active users, or any custom metric. Real-time usage meters with configurable thresholds, overage pricing tiers, and end-of-cycle aggregation for accurate invoicing.

Plan Management & Proration

Flexible plan catalog with monthly, quarterly, and annual billing cycles. Seamless mid-cycle upgrades and downgrades with automatic proration calculations. Support for trial periods, freemium-to-paid conversion flows, and grandfathered pricing for existing customers.

Dunning & Failed Payment Recovery

Automated retry sequences with configurable schedules, exponential backoff, and smart retry timing based on card network recommendations. Multi-channel dunning notifications via email and in-app alerts. Typically recovers 25-35% of failed payments that would otherwise churn.

Invoice Generation & Tax Handling

Automated PDF invoice generation with your branding, line-item breakdowns, tax calculations, and credit notes. GST, VAT, and sales tax compliance with automatic rate determination based on customer location. Integration with accounting systems like Tally, QuickBooks, and Zoho Books.

MRR/ARR Analytics Dashboard

Real-time revenue analytics tracking Monthly Recurring Revenue, Annual Recurring Revenue, churn rate, expansion MRR, contraction MRR, net revenue retention, and ARPU. Cohort analysis, revenue forecasting, and exportable reports for investor updates and board meetings.

Our Billing System Development Process

A proven 5-step process to build billing infrastructure that scales with your SaaS revenue

Billing Architecture Design
We analyze your pricing model, target market, and revenue goals to design the optimal billing architecture. We define plan structures, billing cycles, metering strategies, proration rules, and tax compliance requirements before writing a single line of code.
Payment Gateway Integration
Deep integration with Stripe Billing or Razorpay Subscriptions including webhook event processing, idempotency handling, and retry logic. We configure payment methods, set up customer portals, and build the subscription lifecycle management layer.
Billing Engine Development
Build the core billing engine -- plan management, usage tracking, proration calculations, invoice generation, dunning sequences, and revenue recognition. Every edge case is handled: mid-cycle changes, partial refunds, credits, and currency conversion.
Sandbox Testing & Validation
Exhaustive testing in Stripe/Razorpay sandbox environments simulating every billing scenario -- successful payments, card declines, insufficient funds, expired cards, disputes, refunds, plan changes, and dunning sequences. Load testing to verify performance under high transaction volumes.
Launch & Revenue Monitoring
Production deployment with real-time revenue dashboards, payment failure alerting, and MRR/ARR tracking. 30-day post-launch monitoring to catch edge cases, optimize dunning recovery rates, and fine-tune billing workflows based on actual customer behavior.

What Our Clients Say

"Edesy rebuilt our entire billing system from a fragile cron-job setup to a robust event-driven architecture on Stripe. Payment failures dropped from 8% to under 0.2%, and the dunning system recovered INR 4.2 lakhs in the first month alone that we would have lost to involuntary churn."

C

CTO

Technology at B2B SaaS Platform (Series A)

"We had a complex pricing model with per-seat plus usage-based components and nobody could build it correctly. Edesy nailed the metering engine, proration logic, and invoice generation on the first iteration. Our finance team finally trusts the billing numbers."

VE

VP Engineering

Engineering at Developer Tools Startup

"Migrating 3,000 active subscriptions from a legacy billing system to Stripe without any billing disruption seemed impossible. Edesy planned and executed the migration over a weekend with zero failed charges and zero customer complaints. Outstanding execution."
