I am looking at the same issue this morning. I also have a negative amount showing in the electronic clearing account, when you select Prepare Electronic payment but if you go to Bank Register and select Electronic Clearing Account the balance is showing as Zero and it is not showing on the balance sheet. I cannot see any other problems in the P&L or Balance sheet with the pay reversal or the new pay so I expect support is correct in saying it just stays in the electronic clearing account. Would the boss be happy if you tell him that this is just a glitch in MYOB electronic clearing account (in relation to reversing pays) but you have confirmed that it does not show in the Balance Sheet. Perhaps MYOB can work out a way for us to tidy this up. I will look out for any other replies, also.
Regards
Judy
