New to MYOB but I noticed that the format for the invoice number is not consistent. Our usual invoice starts with INVXXXX but I am seeing, for the same account, some with just INXXXX then nothing but numbers 0000XXXX and then just XXXX. My accounts lady swears blind that she is not tampering with the format. Is there a logical answer to this or is there a way to track any changes and who made them? Cheers, Dave.
