To write a billing statement, first identify your business by its name, address and contact information. Indicate the customer, invoice number and the date, description and amount of each item. Don't forget to add payment terms and conditions at the bottom of the invoice. For instance, let the customer know about a penalty of the invoice is not paid by a deadline.
Set up a billing statement template you can easily complete for each customer. The template should have all of your company information programmed at the top.

Using Excel or a program template, you just enter each itemized description and amount and the total amount is computed for you in the "balance due" or "total" box.
