Questions people ask
What is the difference between an invoice and a receipt?
An invoice asks for payment and is usually sent before money changes hands. A receipt confirms that payment has been made. Many businesses send an invoice first and a receipt once it is paid.
Do I need an invoice number?
Use one. A sequential, unique number makes it easy to track what has been issued and paid, and most tax rules expect invoices to be numbered.
What happens if I make a mistake on an invoice?
Do not silently edit an issued invoice. Issue a corrected invoice or a credit note that references the original number, so your records stay complete.
Is the invoice generator free?
Yes. The generator and PDF export are free, with no signup. The PDF carries a small Kitzone footer.
