If your system is set with assigned salespersons to customer accounts, you receive a prompt at the point of sale to "Change to assigned salesperson". You can clear this prompt by running a utility from the Start menu on the server of main station..
Ensure that all network stations have exited the software.
On your server, or main station, click the Windows button > All Programs (or Apps) > The General Store > Utilties > Clear Assigned Salespersons
Note: This will clear all assigned salespersons.
