Conversational Business Intelligence

JustAsk

JustAsk connects to your BigChange data and lets you ask any question in plain English — no reports to build, no dashboards to dig through, no analyst required. It's a direct line to the intelligence inside your platform.

Trade owners spend 5–10 hours a week on manual reporting. JustAsk gets that time back and replaces guesswork with answers.

Training & Onboarding Agent

FieldReady

FieldReady AI trains every engineer on your processes, your system, and your way of working automatically. New hires get structured, consistent training without pulling a manager off the tools. No trainer required. New techs ramp in days, not weeks. Turnover costs less. And every technician works your way from day one.

Replacing an engineer costs £15,000–£25,000. FieldReady protects that investment.

Job Preparation Agent

JobReady

Before every job, JobReady AI briefs the assigned engineer — pulling job history, site notes, parts requirements, and context from previous visits, and delivering it in a clear pre-job brief. No manual prep. No calls to the office.

Technicians show up prepared. First-time fix rates climb. Return trips drop.

Documentation Agent

JobScribe

AI captures what happens on site in real time. Engineers talk — the system writes. Labor hours, materials used, observations, and compliance notes are captured and filed without the engineer touching a keyboard.

30–60 minutes of admin time back per engineer, per day. Fewer billing disputes. No missing paperwork. Every job documented the moment it's done.

Customer Summary Agent

JobBrief

When a job closes, JobBrief AI generates a professional post-job summary and sends it to the customer automatically. Every job. No manual follow-up. No chasing the engineer to write it up.

Customers get a clear record of what was done. Disputes drop 25–35%. Payments arrive 15–20 days faster. Your business looks professional without anyone doing the extra work.

Customer Communication Feature

Two-Way Messaging

Two-Way Messaging sends automated SMS updates to your customers at every stage of the job. Confirmations, on-the-way alerts, and status updates go out directly from Simpro. No extra app. No manual follow-up. No one chasing the engineer to send a message.

98% of texts are read. Missed appointments drop. Customers stay informed without your office staff lifting a finger.

Automated Time Verification Feature

GPS Time Tracking

GPS Time Tracking uses AI to prompt engineers on arrival and departure, automatically verifying timesheets against location data. No time cards. No manual entry. No disputes about hours worked.

Untracked labor costs disappear. Payroll disputes drop. You stop losing billable time to inaccurate records without asking anyone to do anything differently.

BigChange Lightning agent: GPS Time Tracking

BigChange Lightning is more than an AI feature. It's a platform-wide upgrade that unlocks an evolving roadmap of AI agents, giving your business access to new capabilities as they become available.

Frequently asked questions

What is job management software?

Job management software helps field service and trade businesses plan jobs, schedule mobile teams, complete job sheets, track vehicles, manage customer updates, invoice work and collect payments from one system. For UK field teams, it replaces disconnected spreadsheets, paper forms and separate office tools with a shared view of work.

What is the best job management software for UK field service businesses?

The best job management software for a UK field service business should match its trade workflows, mobile team size, vehicle activity, reporting needs and customer communication. BigChange is built for UK field teams that need scheduling, job sheets, CRM, invoicing, payments, vehicle tracking and AI-supported operational insight in one platform.

How does job management software help mobile teams?

Job management software gives office and field teams the same job information. Dispatchers can assign work, technicians can view job details and update job sheets, customers can receive status updates, and managers can monitor progress, costs, vehicles and payments without waiting for end-of-day paperwork.

Is job management software the same as field service management software?

The terms overlap, but buyers use them differently. Job management software usually describes day-to-day tools for scheduling, job sheets, mobile teams, invoicing and payments. Field service management software can describe the broader category, including service operations, asset history, workforce management and reporting.
