How to Write a Sales Invoice
Sales Invoice Template (

Most businesses generate revenue through sales of the company's products or services. Without collecting fees for the services rendered and goods distributed, the company will eventually lose value, resulting in the closure of the business. This is why it is essential for all businesses, to invoice their clients/customers at the completion of all sales and services transactions. A sales invoice is a detailed statement of the sales transaction between the patron and the establishment. Here's exactly how a sales invoice is created.

    Creating A Sales Invoice

  1. 1

    First, you should determine what type of sale invoice you will need for your business. If the principal business transactions are for sales of goods then you may want to use a computerised software program, which can help draft and tally sums for goods sales on invoices.

  2. 2

    If you decide to create an invoice for your company manually, then start by creating a heading for your invoice. An invoice heading consists of your company's name, logo (if any), address, direct business phone number, operation hours (if any), website address, and other contact information.

  3. 3

    Next, you will want to assign an invoice number for every transaction. This will usually be placed in the upper right corner of the invoice, which is easier for the customer to see.

  4. 4

    The Customer's Name, Account/order number will be displayed beneath the invoice number.

  5. 5

    The body of the invoice includes the information pertinent to the actual sales transaction, including the date of start and completion, if necessary. Here you will categorise parts and services, with proper assigned coding (if any); by listing the prices and charges for the entire transaction, along with a customer key for detailed explanation of the assigned coding for goods and services.

  6. 6

    After detailing the sales transaction summary, manually tally all the fees incurred for the goods/services provided. At the bottom of the invoice, displayed boldly, should be the total amount of expenses incurred by the client, along with payment methods and an expected due date.

Tips and warnings

  • Invoices are great record documents for both the client and the business. Be sure to retain copies for all parties.
  • Leaving a gesture of gratitude at the close of every invoice is also good for business.
