What it does

Once installed, the agent gets a structured playbook for building automated billing systems: recurring charges, subscription states (trial, active, past due, paused, canceled), failed-payment recovery (dunning), mid-cycle proration, and sales tax or VAT handling. It offers a Python-style starting example and points to a reference file with more detailed patterns. It teaches concepts and code structure; it does not connect to any payment provider by itself.

Great for

  • Developers building SaaS subscription billing from scratch
  • Engineers who need a checklist of billing states and dunning steps
  • Teams reviewing how a proration or renewal flow should be structured

Skip it if

  • Handling real payments or tax filings without review by a qualified accountant or payment specialist, since the guidance is generic and tax rules vary by region
  • Production billing that must match a specific provider such as Stripe, because the example uses a generic 'billing' module that is not a real published library

Try asking

  • “Design a subscription state machine with trial, active, past due, paused and canceled states”
  • “Outline a dunning schedule with retries, reminders and account restrictions for failed card payments”
  • “Write a proration function for a customer who upgrades their plan mid-cycle”
  • “Explain how to structure VAT and GST calculation for invoices sold across countries”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Give the agent your actual plan names, billing intervals and currency so the generated logic matches your business rules
  • Ask the agent to check its tax and proration logic against your jurisdiction and your provider's documentation before shipping
  • Have the agent write tests for edge cases such as trial expiry on a weekend or downgrades mid-cycle
