When the circulation desk cash register became too unreliable to continue operating, I built a user-friendly replacement using Microsoft Excel on an existing Windows workstation. Built in one week at a small college library (under 5,000 students), this zero-budget solution handles all circulation transactions - print charges, ID fees, fines, and guest card costs - without new software, vendor contracts, or supplies. Previously, student assistants relied on tip sheets and regularly escalated transactions to senior staff. Now they operate independently with minimal assistance. This poster documents the problem identification, design, and live implementation process, with before/after comparisons and workflow analysis. The solution works with basic Excel skills, though advanced macro versions are available. Attendees will receive an adaptable template for immediate use at their own circulation desk.
