We are using MYOB Premier v19.7 and basically have staff performing two roles:
one undertakes our payroll (HR);
while another undertakes the day to day banking functions including bank reconcil...
As a bookkeeping company, and for very different reasons, we train our clients to only ever use mulitpay for payroll settlement. We also set up their payroll to pay wages from a payroll clearing account. The effect of these two actions is that, on the main bank account, there is nothing to drill down to. The multi -pay from the bank is a Spend Money from the bank to the payroll clearing account. Obviously the Payroll clearing account would also be available to your Admin person and the only way to stop access to that is to appeal to the sensibilities of the staff not to go there. This would mean that you would have to access the file, in strictest privacy (of course) to ensure that your HR has paid exactly as per the original payroll.
All business is built on trust - you trust that your clients will pay you within an agreed time, your suppliers trust that you will follow the rules that you expect of others - why not try trusting the people who you are entrusting your business to, they have access to far more important numbers than the 30% you spend on payroll.
