Freelance Invoice Generator

You finished the work. Now generate a real invoice in 30 seconds.

Tell your agent "invoice Acme Corp" and get a professional, print-ready PDF with itemized line items, totals, payment details, and notes. Not a markdown template. An actual PDF you can email or upload anywhere.

What you get:

• Real PDF generation (Puppeteer + HTML template)
• Itemized line items with dates, descriptions, hours, and rates
• Auto-calculated subtotals and totals
• Your business details and payment info (bank, PayPal, Venmo)
• Auto-incrementing invoice numbers (YYYYMMDD_##)
• Invoice history tracking
• Automatic archiving of billed hours
• Multi-client support with different rates
• Custom payment terms (Net 15, Net 30, Net 60)
• Notes section for deliverables and project summaries

Who this is for: Freelancers and consultants who bill hourly and want professional invoices without paying $15-50/month for FreshBooks or Harvest.

How it works:

1. Track hours in a markdown log (or use the free Freelance Time Tracker skill)
2. Say "invoice [client]" when it is time to bill
3. Confirm the period and line items
4. Get a clean PDF, archived hours, and updated invoice log

Requires: Node.js 18+. Uses Puppeteer for PDF rendering.
