Frequently Asked Questions
What format should invoice numbers use?
Common formats include sequential numbers (INV-0001), date-based (2024-0001), or alphanumeric codes. Choose what works for your accounting system.
Should invoice numbers be sequential?
Many businesses use sequential numbering for easy tracking, but it's not required. The key is consistency and uniqueness.
Can I include my company prefix?
Yes! Adding a company prefix helps identify invoices quickly and adds a professional touch to your billing.
What about invoice number length?
6-10 characters is common. Shorter is easier to reference, but longer gives more room for unique combinations.
