Step by step
- 1. Header: your business name, address, tax ID
- 2. Numbering: next number in your sequence, today's date, due date per your terms
- 3. Buyer: legal name and billing address (match the PO if there is one)
- 4. Lines: description, quantity, unit price — one line per item or service
- 5. Totals: subtotal, discount, tax, grand total; payment instructions in the notes
Details that prevent queries
Explicit due dates, a PO number when the client uses them, and payment instructions on the face of the invoice. Each removes one round of 'can you confirm…' emails.
Sending it
PDF is the standard: print-to-PDF from the generator preserves layout everywhere. Send it from a recognizable address and put the invoice number in the subject line.
Frequently Asked Questions
What if I make a mistake on a sent invoice?
Issue a corrected invoice with a new number, or a credit note cancelling the original. Never edit and resend the same number with different amounts.
Do I need a company to issue invoices?
No — sole traders and freelancers issue them constantly under their own name. Add your tax ID once you are registered.
Is a handwritten invoice valid?
Yes, if it contains the required fields — that is exactly what the blank template is for.
