Frequently Asked Questions
- What must an invoice legally include?
- Typically: seller and buyer identities, unique invoice number, date, itemized description, amounts, and tax. Rules vary by country — check local invoicing law.
- How should I number invoices?
- Sequentially with a year prefix (INV-2026-001, …002). Gaps invite questions from accountants and auditors.
- Can I use this for multiple items?
- This generator handles one line item cleanly. For multi-item bills, generate per item or use full invoicing software.
