Problems while trying to create your transaction. Exception details: Invoice could not be published. Error Returned: The transaction is missing a valid account.
This error message can appear on your invoices when, in Sage 50 US, your company is set to Cash basis. AutoEntry will only publish invoices to a company that it set to an Accrual basis.
To clear this error and allow your invoices to publish, you would need to change this setting in Sage 50 US, and then republish the affected invoices.
