Subscription Billing

Subscription billing is the payment infrastructure that powers the recurring revenue model. Unlike one-time purchases, subscription billing involves automatically charging customers at predetermined intervals — most commonly monthly or annually — and managing the full lifecycle of those payments, including upgrades, downgrades, prorations, and cancellations.

At its core, subscription billing requires several interconnected systems: a product catalog that defines plans and pricing tiers, a payment processor that tokenizes and charges payment methods, an invoicing engine that generates and delivers billing statements, and a dunning system that handles failed payments. Most subscription businesses rely on a payment provider like Stripe, Braintree, or Adyen to handle the payment processing, while using additional tools for the surrounding workflow.

One of the key challenges in subscription billing is payment failure. Industry data shows that 5-10% of recurring charges fail each month, driven by expired cards, insufficient funds, bank declines, and fraud prevention. Without a recovery strategy, these failures lead to involuntary churn — customers who leave not because they chose to, but because their payment could not be collected.

Subscription billing also introduces complexities around tax calculation, multi-currency support, free trial management, and compliance with regulations like PCI DSS and PSD2 Strong Customer Authentication. As businesses scale globally, these requirements become increasingly important.

LostChurn integrates with your existing subscription billing stack to address the payment failure problem. Rather than replacing your billing infrastructure, it layers on top to add intelligent retry logic, AI-personalized dunning, and real-time recovery analytics.
