It would be really good if Supplier (and maybe Customers) had an extra text field, like the Description one, but unlike Description, wouldn't enter that text into each new document uploaded to that Supplier, and would just be a reference, visible at least under Suppliers, possibly also in individual invoices (maybe a hover-able word such as NOTES, which displays the notes when you hover your mouse, or an expandable one, or something like that.)

Specifically in our case, we would like a way to keep track of information about specific companies, such as:
"FYI: VITAL to pay on time - else will suspend webhosting service

23.07.24 confirmed new bank info by phone -T.A.
01.08.25 payment terms have changed - 14 day terms -M.J.
16.11.25 promised payment this week -M.J."

etc

We don't want to keep an third list of suppliers which would need to be manually added to, when Dext and MYOB (which we use) already share the suppliers list, and MYOB still hasn't implemented the Contact Log for the web version, so we are can't do that in MYOB.

This Notes section, for us at least, wouldn't even need to be shared to other services such as MYOB etc, it would be fine to exist in Dext only. (though perhaps exportable as a csv or something, on demand)
