[Key Benefits](#benefits "Key Benefits") [Book a demo](#demo "Book a demo") 01 ## The Company The business runs approximately 250 jobs per month under normal conditions, rising to 15–20 jobs per day during peak season. Twice a year — in June and November — Commercestar runs Mega Sale campaigns that compress 200 to 300 jobs into a single day. Those days run 18 hours straight. Managing that volume — 300 active MA contracts cycling between quarterly and tri-yearly visits, 5,000 customer records, and a technician team dispatched across Singapore — demanded a platform built for field service at scale. On normal days this was friction. On Mega Sale days — with 200 to 300 jobs moving simultaneously — it was a crisis waiting to happen. 02 ## The Challenge Before FieldCamp, Commercestar used ZenBooker for scheduling and KickServe for parts of their workflow. As the customer base grew past 5,000 and MA contracts accumulated, the cracks became structural. The core problem was rescheduling. When a customer needed to move an appointment, there was no automated notification, no system update, and no way to alert the next person in the chain without a phone call. The back office was the single point of failure for every change. The team was stretched. Every person — technicians, dispatcher Hansel Lim, and Andy himself — was operating at capacity with no system to absorb the surge. > “Everybody will be working almost 18 hours every day.” > > Andy YeoOperations Manager, Commercestar Engineering Why they moved > “Hard to reschedule, no notifications sent to customer, customer may miss out on appointment dates, always have to call back office to reschedule.” > > Andy YeoOperations Manager, Commercestar Engineering 03 ## The Solution: One Platform for Contracts, Dispatch, and Customer Communication Commercestar evaluated FieldCamp to replace ZenBooker — their primary scheduling tool. The switch to FieldCamp also absorbed what KickServe was handling, consolidating the entire operation into a single platform. > “I was more interested in FieldCamp to take over ZenBooker… But I can say that FieldCamp did well for taking over KickServe.” > > Andy YeoOperations Manager, Commercestar Engineering Three capabilities drove the decision: ### MA Contract Automation Commercestar’s 300 maintenance agreements — cycling quarterly and tri-yearly — generate predictable but high-volume recurring jobs. FieldCamp schedules these automatically from contract configuration, triggering visit reminders and technician assignments without manual intervention. The back office no longer tracks upcoming MA visits in a spreadsheet or calendar. ### Automated Customer Notifications Every reschedule, confirmation, and reminder now goes directly to the customer — no callback required. When a technician slot changes, FieldCamp sends the update. Andy’s team stopped being the message relay between customers and field technicians. ### AI Dispatch for High-Volume Days On Mega Sale days, Commercestar’s dispatcher Hansel Lim manages job volume that would overwhelm any manual system. FieldCamp’s AI dispatcher evaluates technician availability, location, and skill set to assign the right person to each job — at the speed the campaign demands. > “We really need a proper system to run this.” > > Andy YeoOperations Manager, Commercestar Engineering 04 ## The Impact: From Manual Coordination to Automated Operations ### 300 MA Contracts Running Without Manual Tracking Every maintenance agreement in Commercestar’s portfolio is now managed in FieldCamp. Quarterly and tri-yearly cycles are configured once — visits are generated automatically, technicians are assigned, and customers receive their reminders without anyone in the back office chasing the calendar. ### Mega Sale Days Under Control 200 to 300 jobs in a single day used to mean 18-hour shifts and a back office fielding calls from customers who missed appointments. With FieldCamp dispatching jobs and notifying customers automatically, the campaign-day load is manageable — the same volume, with a system absorbing the coordination that previously fell on people. ### A Platform Built to Scale Commercestar runs on FieldCamp’s Growth plan — 10 seats covering 8 field technicians, operations manager Andy Yeo, and dispatcher Hansel Lim. The team is actively onboarding additional managers and technicians as they scale. > “We are planning to add more — we will have new teams coming, as well as managers coming in.” > > Andy YeoOperations Manager, Commercestar Engineering FieldCamp scales without re-implementation. Adding technicians, managers, and new service zones happens within the same system — no migration, no new tooling. 05 ## Key Benefits ### MA Contract Automation at Scale * 300 active contracts managed without manual scheduling * Visits, reminders, and technician assignments generated automatically from contract configuration * Quarterly and tri-yearly cycles run without admin intervention after initial setup ### Zero-Callback Rescheduling * Customers receive automated notifications on every booking change * Back office stopped being the relay between field technicians and customers * No manual follow-up required when slots move or technicians are reassigned ### Surge-Ready Dispatch * Mega Sale days with 200–300 jobs managed through AI dispatch * No manual assignment, no missed appointments, no customers calling in * Platform handles campaign-day volume without additional admin headcount ## Running MA contracts across Singapore?
