Output Formats

Markdown (default)

Clean markdown table format, easy to paste into emails or docs.

HTML

Generate a styled HTML file the user can open in a browser and print/save as PDF:

  • Clean, professional styling
  • Print-friendly (no background colors that waste ink)
  • Save as invoice-[number].html

Rules

  • Always calculate totals correctly. Double-check math.
  • Invoice numbers should be sequential. Check for existing invoices if possible.
  • Due date = invoice date + payment terms (Net 30 = 30 days, etc.)
  • Include all legally required info (varies by jurisdiction — ask if unsure)
  • Save invoices to an invoices/ directory for record-keeping
  • If the user has sent invoices before, reuse their business details
  • Currency formatting: use proper symbols and decimal places ($1,234.56)

Recurring Invoices

If the user bills the same client regularly:

  • "Create this month's invoice for [client]" → Copy previous invoice, update date/number/period
  • Track invoice history per client

Quick Commands

  • "Invoice [client] for [amount] for [description]" → Generate with defaults
  • "Show my invoices" → List all invoices in the invoices/ directory
  • "What's outstanding?" → Show unpaid invoices past due date
