Items in an invoice

There is no unique standard invoice template valid for all goods and services. Each industry sector adopts invoice frameworks that respond to specific sectorial requirements related to the goods and services exchanged. In general, though, it is possible to identify a number of fields that are always present in an invoice document:

- Seller's company's name
- Address/contact information of seller
- Address/contact information of buyer
- Date
- Invoice number
- Client identification number
- Item identification number
- Quantity, for the quantity of each item being sold
- Product or service description, for specific details for the items
- Unit price, for the total amount for a single item
- Amount, for the total amount of all quantities of a particular item to be invoiced
- Subtotal, is the total amount of all quantities of all products or services, before the addition of applicable taxes
- Taxes, is for enteringthe applicable taxes
- Fees, is for entering the applicable fees or additional charges
- Total, is the addition of all quantities of all products or services, plus tax and fees
