Invoice Generator

Create professional invoices from text descriptions or structured data.

Workflow

  1. Collect invoice details from the user (or parse from prompt):
    • Sender (business name, address, email)
    • Recipient (client name, address, email)
    • Line items (description, quantity, unit price)
    • Invoice number, date, due date
    • Payment terms/methods
    • Tax rate (optional)
    • Notes (optional)
  2. Read the template at assets/invoice-template.html
  3. Replace placeholders with actual data, calculate totals
  4. Save as .html file — user can open in browser and Print → PDF

Calculations

  • Subtotal = sum of (quantity × unit price) for each line item
  • Tax = subtotal × tax rate
  • Total = subtotal + tax
  • Always format currency with 2 decimal places

Template Placeholders

Placeholder Description
{{INVOICE_NUMBER}} Unique invoice ID
{{INVOICE_DATE}} Issue date
{{DUE_DATE}} Payment due date
{{SENDER_*}} Sender name, address, email, phone
{{CLIENT_*}} Client name, address, email
{{LINE_ITEMS}} HTML table rows for items
{{SUBTOTAL}} Pre-tax total
{{TAX_RATE}} Tax percentage
{{TAX_AMOUNT}} Calculated tax
{{TOTAL}} Final amount due
{{PAYMENT_TERMS}} Payment instructions
{{NOTES}} Additional notes

Defaults

  • Currency: USD (configurable)
  • Tax: 0% unless specified
  • Due date: 30 days from invoice date unless specified
  • Invoice number: auto-increment or user-specified

Common Mistakes to Avoid

  • Don't guess line items — if the user is vague ("invoice them for the work"), ask for specifics (hours, rate, deliverables)
  • Don't invent sender details — use what the user provides or ask
  • Don't skip the math — always verify subtotal + tax = total. Rounding errors on invoices are unprofessional
  • Don't add fake payment links — only include payment methods the user explicitly provides
