Hi Snowy2
We recently moved our payroll from MYOB to Employment Hero using both their HR and Payroll functions (not rostering though)
As long as your Chart of Accounts is set up correctly, the process is really easy. Just follow their support notes and the importing of the journal is easy. If you use jobs in MYOB you will need to make sure you untick the "Warn if Jobs are not assigned to All Transactions" when you import the journal or you will get an error message.
Highly recommend doing a dummy payrun from beginning to end that you can delete in Employment Hero and MYOB (before importing entitlement balances) - just don't report STP or publish payslips. We are a NFP so we had to take time to work out how the accured leave provisions came across but now OK.
I do miss some of the payroll reports in MYOB and the ease to manually change details, but the overall payroll process is more streamlined and provides other added benefits.
Good luck!
Jo
