Invoices are forms that are given to customers to provide information. Categories of invoices include sales, work orders, quotes, estimates and purchases. Most commonly, however, invoices are thought of as a form that is used to show a customer how much money they owe you. Invoices need to provide information to the customer in a clear and understandable way so that they know exactly how much money they owe, what they owe it for, when it is due and how they can pay it.

Step 1.

Utilize an invoice template or create your own. There must be a place for the information of the company to which you are submitting the invoice, your company's name and address, an amount due, what the money is owed for and when the money is due. If you create your own invoice template, you can include your logo and company information at the top. There are also printed invoices that can be purchased from office supply stores and filled out manually. In addition, your accounting software may have an invoice feature where you simply enter the information and print it out.

Step 2.

Include an invoice number on the invoice. This will give you a way to keep track of the invoices that are outstanding at any given time.

Step 3.

Include sales tax on the invoice if necessary, depending on the service or product provided to the customer.

Step 4.

Provide detailed information about the services or products that the money is owed for. Include a date that the money is due so that there is not an excuse to put off paying you. Include the penalties for late payments if you have such policies in place.

Step 5.

Give the customer information about where to send the payment and to whom to make the check payable.
