on a per employee basis

you can specify a default value for all new employees

you can turn the feature off if not paying by cash.

From the front screen select Setup then Company Defaults then Payment Method.

All new programs are supplied with cash rounding turned off by default. To activate the feature, select payment by cash from the dialog below. Changing this company default value will change the value for all employees where a value has not been explicitly set for an employee. All new employees will have the new setting.

From the employee modification screen, select Direct Credits then click the how paid panel shown below.

A dialog similar to the above is shown, only this time the setting relates to the selected employee only.

If you previously paid staff in cash, then change to payment using direct credits, you can turn off all rounding irrespective of the employee settings.

The simplest way to do this is to select Setup from the Coin Split report, and round to 1 cent. This effectively eliminates all rounding.

Alternatively turn off all rounding from the direct credit setup screen.
