What the file says
# Billing Automation
Master automated billing systems including recurring billing, invoice generation, dunning management, proration, and tax calculation.
## When to Use This Skill
- Implementing SaaS subscription billing
- Automating invoice generation and delivery
- Managing failed payment recovery (dunning)
- Calculating prorated charges for plan changes
- Handling sales tax, VAT, and GST
- Processing usage-based billing
- Managing billing cycles and renewals
## Core Concepts
### 1. Billing Cycles
**Common Intervals:**
- Monthly (most common for SaaS)
- Annual (discounted long-term)
- Quarterly
- Weekly
- Custom (usage-based, per-seat)
### 2. Subscription States
```
trial → active → past_due → canceled
→ paused → resumed
```
### 3. Dunning Management
Automated process to recover failed payments through:
- Retry schedules
- Customer notifications
- Grace periods
- Account restrictions
### 4. Proration
Adjusting charges when:
- Upgrading/downgrading mid-cycle
- Adding/removing seats
- Changing billing frequency
## Quick Start
```python
from billing import BillingEngine, Subscription
# Initialize billing engine
billing = BillingEngine()
