What are sales invoices?
A sales invoice is an accounting document used to record a transaction between two companies or between a company and a customer.
A sales invoice records the provided services or products, the amounts due for payment in exchange for those items, the agreed payment terms and due date, the applicable tax rate, and any other important notes or information.
What are the types of sales invoices?
Understanding the types of sales invoices helps your company identify their purposes and use them effectively, enabling you to determine the appropriate invoice type to apply. Sales invoices are divided into four main types, as outlined below:
1/ Simple sales invoice
This is the most commonly used type of sales invoice in most sales transactions. It includes the basic elements that must be present in any sales invoice, which will be explained in detail later in the article. There may be slight modifications to these elements depending on the nature of the transaction.
2/ Proforma (preliminary or estimated) sales invoice
The purpose of this type of sales invoice is to clarify the amount the customer is expected to pay for the services or products they will receive. It differs from the standard or simple sales invoice, which requires immediate payment upon receipt.
3/ Recurring sales invoice
These invoices are issued repeatedly to customers who purchase a service or product on an ongoing basis but at specific time intervals, such as internet service invoices.
4/ Commercial sales invoice
This is the most complex type of sales invoice. It is a document issued by the seller to the buyer in an international transaction, and it must clearly detail the prices and quantities of the goods sold, as well as the terms of the commercial relationship between the seller and the buyer.
What information should a sales invoice include?
A sales invoice must include a number of essential and secondary elements to provide a complete description that benefits both the seller and the buyer. Below are the main elements of a sales invoice:
1/ Company details (seller)
The seller’s information includes their name, job title, and contact details such as phone number and email.
2/ Customer details (buyer)
Customer information includes their name, address, and contact method.
3/ Invoice number
The invoice number is referred to in English as Inv. No. It is a unique code assigned to each invoice, making it easier to track, review, and document invoices.
4/ Invoice date
The invoice date indicates the actual time when the sales transaction took place. In most cases, the due date is calculated starting from the invoice issuance date.
5/ Sales transaction details
This includes the product items and quantities purchased by the customer. In the case of services, they are described in a simplified manner.
6/ Amount due
The total amount that the customer must pay for the services or products received is clearly stated. Additional notes may also be included, such as breaking down the total into detailed line items to give the customer a clear view of costs, and specifying tax rates, shipping fees, and discount percentages for offers or preferred customers.
You can also review the tax calculation guide from the invoice, which explains how to calculate tax step by step from the total invoice amount.
7/ Payment terms
Clarifying payment terms in a sales invoice defines the time period within which the invoice must be paid, helping the seller manage cash flow accurately and efficiently.

What is the importance of sales invoices?
The importance of sales invoices stems from their role in tracking sales activity within a company and documenting financial transactions for future reference and for use in end-of-period financial reports. The importance of sales invoices includes the following:

A sales invoice answers the following questions:
- What is the amount of realizable revenue generated by the business during a specific accounting period?

- What are customers’ purchasing preferences?
2/ Ensuring payment collection
Invoices obligate customers to pay the amounts due, especially through automated reminders sent by electronic accounting software at specific time intervals.
3/ Maintaining sales invoice records for tax purposes
Sales invoices help large companies and individuals complete tax documentation and the required information in tax returns submitted for collecting sales taxes.
4/ Organizing accounting records
Sales invoices help maintain organized accounting records. These records are used to review cash flows, payment tracking, monitor inventory levels based on incoming orders, and forecast future sales based on previous sales data.
