Invoice Numbering Best Practices

Client-Seq ACME-001 Multiple clients

Date-Seq 20260129-01 Date-based tracking

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.
