OpenCRM can be used to track Sales Orders and Invoices that require re-invoiceing at regular intervals....

If you have Invoices that recur on a regular period (7 days, Monthly, 28 Days, 180 days, Year), which you can define, OpenCRM can help you track these recurrences.

All Sales Orders are displayed in a grid, based on criteria that you decide, and visually display if they are overdue, current or due in the future. These Sales Orders, when they appear, can easily create NEW Invoices for the recurrence period.
