To change your MYOB export settings, go to the Settings page in the MYOB section of the sidebar.
Export PDF attachments will attach the original PDF to the invoices created in MYOB. You can disable this setting if you do not want the PDF to be sent to MYOB.
Prevent sending duplicates will prevent invoices from being sent to MYOB if there is already a bill from the same contact with the same invoice number in MYOB. You can disable this setting if you want our software to send all invoices to MYOB without checking for duplicates first.
