# Subscription billing edge cases

> Pause, swap, gift, skip — the long tail of subscription billing that Shopify Subscriptions misses.

**Sector**: [E-commerce Infrastructure](https://signals.gitdealflow.com/niche-down/ecommerce-infrastructure)  
**Build cost**: Month-long build  
**Deal velocity**: Steady — one deal per month

## Why now

Subscription growth is back. The edge cases (pause, swap, gift) drive retention and upsell.

## What the signal looks like

Repos with subscription state machines, Stripe / Recharge adapters, and customer-portal frameworks.

## Public examples
