Build automated billing systems for recurring payments, invoicing, subscription lifecycle, and dunning management. Use when implementing subscription billing, automating invoicing, or managing recurring payment systems.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

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()
…

How to install

The exact contents, by fingerprint
mdr add seaworld008/commonly-used-high-value-skills/billing-automation@sha256:6663aea0dc961520

The line at the top of this page pins the label v1.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
