BigChange Lightning

The AI management platform built for the trades

BigChange Lightning is the AI built into your platform. It doesn't replace the way you work — it gives your business capabilities you've never been able to staff for. Our AI agents handle the work your margins never supported hiring for.

Conversational Business Intelligence

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 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.
