Frequently asked questions
Job scheduling software syncs changes to mobile devices in real time. When you move a job in the platform, engineers see the update within seconds on their field service app. Spreadsheets require phone calls, text messages, or manual checking to confirm schedule changes.
The software also handles route optimization automatically. It calculates the most efficient order for jobs based on location, traffic, engineer skills, and vehicle equipment. Spreadsheets leave this planning to manual work.
Yes. Create an emergency job and drag it onto any available engineer's schedule. They receive an instant notification on their mobile app with customer details, site location, and job requirements.
The job scheduling app shows which engineers are nearest to the emergency location. You can reassign scheduled work to other team members and dispatch the closest engineer immediately.
The field service app works offline. Engineers view their schedule, access job details, complete forms, capture photos, and collect signatures without connectivity.
Once their device reconnects to wifi or mobile data, all updates sync automatically with the office system. You see completed jobs, photos, and customer signatures appear in real time.
Yes. Customers receive automated appointment confirmations by SMS or email. On the day of service, they get a tracking link showing their engineer's current location and estimated arrival time.
This feature reduces phone calls asking when engineers will arrive. Customers see live updates if traffic delays change the arrival window.
The platform integrates with Xero and Sage for automatic invoice synchronization. Completed jobs flow from your field service scheduling software into your accounting system without duplicate data entry.
Engineers mark jobs complete on their mobile app. The office system generates invoices immediately and sends them to your accounting platform.
The job scheduling app calculates the shortest driving distance between appointments while accounting for traffic conditions. It sequences jobs in the optimal order to minimize backtracking and unnecessary miles.
BigChange customers report 11% less drive time and 10% lower fuel consumption on average. Route optimization runs automatically whenever you schedule or reschedule jobs.
Yes. Set up recurring service schedules for PPM work. The field service scheduling software generates work orders automatically at the intervals you specify.
The system sends customer reminders before inspections come due. You can schedule annual boiler services, quarterly equipment checks, or monthly maintenance visits without manual calendar management.
Drag and drop makes bulk schedule changes quick and painless. Select multiple jobs assigned to one engineer and drop them onto another team member's calendar. Both engineers receive instant updates on their mobile devices.
The job scheduling software UK businesses use also includes an intelligent scheduling assistant. It can reassign hundreds of jobs in bulk based on engineer location, skills, and availability.
The platform tracks every engineer's capacity and existing commitments in real time. When you drag a job onto a schedule, the system checks for conflicts automatically.
If an engineer already has a job scheduled during that time slot, the software prevents the double booking. Your customer booking portal also blocks appointment times that would create scheduling conflicts.
The platform connects to your parts inventory system. Check stock levels at your warehouse, in engineer vans, and at supplier locations before assigning jobs.
Add required parts directly to the work order during scheduling. Engineers see the parts list on their field service app and can verify they have everything before leaving for the site.
Build mandatory risk assessments and safety forms into your job workflows. Engineers cannot mark jobs complete until they fill out required compliance documentation on their mobile device.
All forms include date and time stamps showing who completed them. This creates a complete digital audit trail for health and safety compliance, insurance requirements, and industry regulations.
