By default, Duoplane will always send packing slips as an attachment along with the POs sent to vendors. This option can be disabled at a global or vendor level. To disable at a global level:
- In your Duoplane Retailer account, navigate to Main Menu > Settings > Order Processing
- At the bottom section of the page, you will see a section titled Other options
- Toggle the option to Include packing slips to "YES" or "NO"
To change this at a vendor level, navigate to the vendor's purchase order preferences for emails.
