No, I wouldn’t go to effort of setting up employees as I presume that you handle all their payments in Sage.
Just set up your expense accounts (wages, etc) and your liabilities accounts (tax, national insurance/PRSI/social contributions, etc) and then do a Spend Money transaction with the total amounts each month
Debit wages
Credit tax due
Credit National Insurance
Credit bank
I think that’s the way I’d handle it - maybe others will have a different view
Another way would be to set up an employee X who represents all your employees. Then you could set up payslip items to cover the wages, deductions & contributions you make.
Then do 1 payslip per month to cover all your employees using the summary totals from Sage. That might give a clearer view of the transactions than the “Spend Money” I advocated in the last reply
Also, how will you handle employee expense claims, if you have any?
