Would be quite useful to be able to upload files to a specific supplier details page. Just as you can for invoices.
I have one that has just sent a file that needs to be filled in for every order. I’m 100% sure I will lose this file and so it would be useful (for me 
) to upload it to quickfile.
Come to think of it there are numerous files that would be useful stored on quickfile supplier accounts - shipping docs, their quotes / estimates and general files.
