I am looking for advice on the correct use of accounts in Sage One. My scenario is as follows:

Employee does not want to take all commission due but rather a set amount each month.
I still want to process all payments via Sage Payroll, which will allocate the commission amount to the Salary Control Account in Sage One.

From the accounting side I will create a current liability account for the excess commission owed.

1 - Which account should be debited in Sage One to credit the excess commission to the above liability account?
2 - When I process the payment from Payroll on a month where I need to top up commission, which account do I debit when I credit the new liability account?

Hope I am making sense!?
