billing-automation is a skill from wshobson/agents. Claude loads it when you build recurring billing, invoicing or dunning (retrying failed payments). SKILL.md covers four ideas: billing cycles, subscription states (trial, active, past_due, canceled), dunning and proration. It ends with a short Python quick start that creates a subscription with a 14-day trial.

The longer examples live in references/details.md: subscription lifecycle, billing cycle processing, dunning, proration, tax calculation, invoice generation and usage-based billing. The folder bundles no scripts. The examples include a call to stripe.Charge.create, so read any code before you run it.

Good for

Developers adding recurring billing to a SaaS product
Teams automating invoices and failed-payment recovery (dunning)
Builders who need prorated charges or usage-based billing

Permissions

Medium risk

The skill holds instructions, but its examples show code that charges cards and emails customers when run. Use test-mode keys while you build and read generated code before you run it.

What it can do

Read your data
Create and change things
Delete things
Read-only mode

Watch out for

Example code can charge customers
references/details.md has a charge function that calls stripe.Charge.create. Run any adapted version against test mode first. github.com
Dunning examples send customer emails
The dunning section calls send_dunning_email on a 3, 7 and 14 day schedule. Check the recipients and templates before you enable it. github.com

Questions

How do I install the billing-automation skill?

Use the install box above. The skills CLI command installs only this skill. The plugin route installs payment-processing, which holds 4 skills, 1 agent file(s) and 0 command file(s) in the repo.

When does Claude use billing-automation?

SKILL.md says to use it when implementing subscription billing, automating invoicing or managing recurring payment systems. Claude loads it when your request matches that description.

Does billing-automation need a Stripe or payment API key?

SKILL.md names no key. The example code in references/details.md calls Stripe (stripe.Charge.create), so code you adapt from it needs your own Stripe account. Use test mode while you build.

Is billing-automation safe to install?

The folder holds two Markdown files and no scripts, so installing it adds instructions only. The risk is in code you run from its examples, which include charging a customer and emailing dunning notices. Read generated billing code before you run it.

What else is in the payment-processing plugin?

The repo folder holds billing-automation, paypal-integration, pci-compliance and stripe-integration, plus one agent file.

Does billing-automation work in the Claude app or Codex?

The install box lists a zip upload for the Claude app and a plugin route for Codex. The wshobson/agents README names Claude Code, Codex CLI, Cursor, OpenCode, Antigravity CLI, GitHub Copilot and Pi as supported tools.
