Tips
- Never reuse invoice numbers
- Keep numbers sequential (gaps may raise audit questions)
- Include prefix for different services if needed
Tips for Better Results
- Provide complete info - The more details, the better the invoice
- Specify currency - USD, EUR, GBP, CNY, etc.
- Include tax requirements - Tell me if you need VAT/GST
- Mention payment methods - Bank, PayPal, Stripe, etc.
- Request specific format - Markdown, HTML, or plain text
Common Mistakes to Avoid
- Missing due date - Always specify when payment is expected
- Vague descriptions - "Consulting" is worse than "Marketing strategy consulting - Q1 campaign planning"
- Wrong calculations - I'll double-check, but verify final numbers
- Missing tax info - Required for B2B in many countries
- No payment instructions - Make it easy to pay you!
Limitations
- I generate text invoices, not PDFs directly
- Tax calculations are estimates - verify with accountant
- Can't integrate with accounting software
- Don't know your specific local requirements
Languages
Works with multiple languages including English and Chinese. Just specify your preferred language when requesting an invoice.
