Are there any files attached to the Purchase Order that gets sent to the Vendor?
A PDF file containing only the Purchase Order itself will be emailed to the Vendor after its final approval. If you attach any files to the Purchase Order, they will not be sent.
However, when you select that your Purchase Order should be sent automatically to the Vendor after its final approval, you'll see an additional dialogue for attaching files to that email.
Files from both sections (attachments to a Purchase Order and Vendor attachments) will be pushed to QuickBooks Online. If you need to attach a file to a Purchase Order and send the same
file to a Vendor, we recommend to attach this file in the Email to
Vendor section only:
Email to Vendor section can be automatically enabled and checked in the settings by Organisation Administrator. Please note: it is not possible to attach duplicates (files with the same name). If you want to attach the same file in both sections, you'll need to use a different name for one of them.
