The Opportunity

Problem

Small auto repair shop owners lose revenue due to inefficient scheduling and customer no-shows without affordable, simple software solutions.

Solution

RosterFix uses AI to manage schedules and auto-notify waitlist customers when slots open from no-shows or cancels. Owners set availability once, and the system optimizes fills via SMS pushes. Revenue soars as empty bays become instant bookings.
