Go to the
Customers & Suppliers menu
Click on the Suppliers tab
Click on Suppliers blacklist
The blacklist lets you block all incoming documents sent by a supplier.
To blacklist a supplier:
Click on Add supplier
Enter the email address you want to prevent from sending documents to your Banqup account
All emails sent by a blacklisted email address go straight to the recycle bin.
To remove a supplier from the blacklist, click on Delete.
Alternative method
Another way to blacklist a supplier is by refusing an invoice sent by a supplier via email.
