In a small business, the receptionist may be responsible for inputting much of that data in the first place, and it may just live on the receptionist's computer.

In fact in some companies outside of tech proper with smaller headcount and less technically minded management, by the time the boss decides to look into systems like HRIS, CRM, ERM, and such the receptionist, office manager, and/or the interns already have about 837 Excel macros doing most of that work.
