A feature every B2B SaaS should have:

"Send this user a file, securely, through their login (and specifically not as an email attachment)."

Every system eventually recapitulates email but you don't have to recapitulate email's infelicities for B2B file transfer, such as:

a) no verification on recipient
b) content default-persisted indefinitely
c) lack of an edit/yank button

"What sort of things do you end up sending here?"

Ad hoc reporting is very common support request for many SaaSes. Incident-related comms. ("We manually corrected the following 57 records created during the browntime.") Returning user-requested forms that contain sensitive info.

Also you will, as time goes to infinity, eventually have a circumstance where you will be asked "Are we absolutely positive that X received this document and can we demonstrate that to the satisfaction of a skeptical but reasonable third party?"

(This could totally be a business, by the way, given the pain involved in building this. Inserting you into the loop does theoretically increase attack surface but are you going to do a worse job that an agency looking up S3 docs to figure out 47th checkbox in the bid doc?)
