External ID
To export an Invoice, the customers must have an External ID that links them to the customer in MYOB Advanced.
FieldInsight Invoices cannot be exported if the Account Customer External ID is missing
If a customer has an incorrect External ID the Invoice will be created on the wrong customer in MYOB
Importing your customer from MYOB will automatically import the External ID form MYOB
For MYOB Advanced setup see MYOB Advanced integration setup
