Spend your advertising dollar wisely. Our Offer Codes feature allows you to assign a particular offer code to any marketing campaign run by your company. These include television commercials, radio spots, newspaper ads, or maybe postcards your company sends out. You can group together invoices which resulted from a particular offer code. You have the option to print different offer code reports. These include a report of each offer code or a summary report of revenue by offer code. As a result, you can track the revenue generated from each offer code, and see which campaigns are most successful.
