Worked example
Logo design 1 × 500.00 with a 10% discount (450.00), and 2 boxes of business cards at 45.50 (91.00). Tax at 20% on 541.00 is 108.20, so the invoice total is 649.20. With 200.00 already paid as a deposit, the balance due is 449.20.
Invoice, proforma invoice or receipt?
An invoice asks for payment for something you delivered. A proforma invoice is a preview of an invoice sent before delivery, often for a deposit or for customs; it is not a tax invoice. A receipt confirms that payment was received. To turn this invoice into a receipt, set the stamp to PAID.
For businesses: let the invoicing run itself
If you send more than a handful of invoices a month, the time goes on copying details, checking payments and chasing. Raising invoices, matching payments and chasing overdue clients is routine work an AI worker can run end to end, with your team only checking exceptions. Book a free automation audit and we will show you what it would take off your desk.
Please note: this generator does the arithmetic and layout. It does not give tax advice, and some countries require extra details or e-invoicing systems. Use the country pages for local tax invoices and check with your accountant.
