Possible Solution to avoiding Verification Process
This suggestion has probably been suggested by others, so it's not an original idea...but, here goes! The solution around avoiding the verification process is to simply print the invoice as a pdf and attach it to an email. Ironically, almost all clients/customers prefer this anyway as they do not, unfairly I might add, invoices sent from within MYOB anyway. So there you have it. PDF the invoices and email them as attachments which identifies the sender with email signatures and the added bonus of attaching supporting documentation to the invoice such as their PO and/or timesheets, etc and CC the email to various email addresses if needed.
