Import CSV to UPDATE user profile fields?

Here’s the idea, please tell me if Batch Create or another plugin can do it:

-have a list of users

-keep accounting records in QuickBooks (obviously not synced to WordPress)

-export users’ records and their current balance due once per week/month

-then, instead of calling for their balance, they could just login to their account and see one of their profile or other fields that says Current Balance: $xxx.xx

Any ideas?

Again, this is for updating existing WP users, not one-time creating new users.

Thank you.
