What is an Invoice?
An invoice is a commercial document issued by a seller to a buyer, detailing the products or services provided and the amount owed. It serves as a formal payment request and a legal record of the transaction. For freelancers and small businesses, invoices are essential for maintaining cash flow and accurate bookkeeping.
What Should an Invoice Include?
- →Your business name, address, and contact information
- →Client name and billing address
- →Unique invoice number for tracking
- →Invoice date and payment due date
- →Itemized list of products or services with quantities and unit prices
- →Subtotal, applicable taxes (VAT), and total amount due
- →Payment terms and accepted payment methods
- →Optional: your logo and personalized notes
How to Calculate Invoice Totals
Invoice calculations follow a standard formula: Subtotal = sum of all line items (qty × unit price). Discount Amount = Subtotal × (Discount% / 100). Tax Amount = (Subtotal - Discount) × (Tax% / 100). Total = Subtotal - Discount + Tax. Our tool handles all of this automatically as you type.
