What is an Invoice Generator?
An invoice generator creates professional billing documents with structured line items, automatic calculations, and customizable fields. It handles the arithmetic, formatting, and layout so you can focus on the business relationship.
Invoice elements:
Header: Your business info, logo
Client: Their name, address
Items: Description, quantity, rate, subtotal
Summary: Subtotal, tax, discount, total due
