Accountright duplicated invoice numbers

[Michaelly]

MYOB is allowing duplicated invoice numbers for sales.

In settingsit is set to new number each invoice.  This should happen regardless of whether it is a different client or another invoice for the same client.

Does anyone else have this issue and is there a fix?

Hi @Michaelly 

If you wish to prevent this from happening, I would suggest turning on the warning option via Setup > Preferences > Sales > Warn for Duplicate Invoice Numbers on Recorded Sales. If it's already turned on, turn on Warn for duplicate Invoice numbers and Customer PO numbers too, and let us know if the duplicate warning is then presented.
