How can i manage the advance payments to employees? I am also unable to see payslip

I have 3 Permanent employees and 5 contractual (assignment based) employees.
during the monthly period some employees demands advance payments against their overtime and salary.

How can i manage them? currently I am entering those amounts in journal enteries but those are unbalanced.

When you advance the payments you would use Spend Money and for the Account you would use Employee Clearing Account + Employee sub-account.

Then under the Employees tab you would see that advance listed as:

Journals shouldn’t be used for cash transactions.

OK I got maximum but please explain how will i spend money? Should i use Purchase invoice for such advance transactions?

Go to the Cash Accounts tab and select Spend Money and then select the bank/cash account that the advance is being paid from.
