I will be moving my payroll over to another software provider due to the Quickbooks/Keypay price increase.

In the new software I have entered the BMS ID and each employees opening balances as of the date of my final pay run with quickbooks (30/3/21). I have also added the new softwares ID in my ato business portal.
Do I need to do anything in Quickbooks to ensure there are no double ups of info reported to ATO? I have read some info that says "zero the employee ytd values in the old software" but I cant find any info on how to do this in Quickbooks?
