Acquiring your own invoice template will surely aid you in dealing with your small-scale business. This is a good way in starting your career in entrepreneurship. A free invoice template is merely a Rich Text Format (.rtf) which you can easily edit. It includes a special field which begins with a percent (%) character. You can simply insert a table in a document and perform the calculations afterwards. A Time Logger will make a copy of your invoice data and replace information with actual values from the time records. However, you should keep in mind that the Time Logger needs to identify the.exe program file that you are using. To generate an invoice, you must first fill the costumer information and enter the invoice amounts in the table. To save an invoice document, you must save it as a Word Template, with a.dot file extension.
