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.

JustAsk

FieldReady

JobReady

JobScribe

JobBrief

Two-Way Messaging

GPS Time Tracking

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.

Frequently asked questions.

What is a job quote template, and why do I need one?

A job quote template is a standardised format used to create accurate and professional job estimates for clients. It ensures consistency, saves time, and reduces the risk of errors in the quoting process. Using a template simplifies administrative tasks, enhances customer trust, and speeds up decision-making by providing clients with clear and concise information about job costs and scope.

How can BigChange help with creating digital job quotes?

BigChange lets you build and send professional job quotes directly from the platform: on desktop or mobile, in the office or on-site. You can create templated quotes with pre-built line items, labour rates, and materials, so engineers or office staff can generate accurate estimates quickly without starting from scratch. Quotes are sent digitally to customers, who can review and approve them online. Once accepted, the job flows straight into scheduling. For businesses still quoting on paper or in spreadsheets, BigChange replaces that entire process in one place.

What is BigChange Lightning, and do I need it?

BigChange Lightning is the AI built into your BigChange platform. It adds four AI agents covering engineer training, job preparation, documentation, and customer communication — plus JustAsk, which lets you ask your business any question in plain English and get an instant answer. If your team is spending time on manual reporting, paperwork, or onboarding, Lightning is built for you. Book a demo to learn more.

Will AI replace my engineers?

No. BigChange Lightning gives your business the capability you couldn't afford to staff for — it doesn't replace the people you already have. Your engineers keep doing the skilled work. AI handles the documentation, the briefing, the training, and the customer follow-up that currently eats time or doesn't get done at all. Your team is freed up to do more of the work that actually earns.

What features does BigChange’s job management software offer beyond quoting?

BigChange is an end-to-end job management platform built for field service businesses. Beyond quoting, it covers job scheduling and dispatch, mobile workforce management, real-time vehicle tracking, customer portals, invoicing, contract management, and reporting. BigChange Lightning adds AI capability on top, including automated job preparation, engineer training, documentation, and customer communication, so your back office and field team stay connected from the first quote to the final invoice.

Can BigChange’s job quoting software integrate with other tools I use?

Yes. BigChange integrates with a wide range of business tools including accounting packages like Xero and Sage, CRM systems, and payment processors. Because quoting, scheduling, invoicing, and reporting all live in one platform, you reduce the number of integrations you need, but where connections matter, BigChange is built to fit into your existing workflow.

Is BigChange suitable for small businesses?

BigChange is designed for field service businesses that are ready to replace manual processes, spreadsheets, or disconnected tools with a single platform. Whether you're running a team of five engineers or fifty, BigChange scales with you. Smaller businesses benefit most from the time saved on admin, quoting, and scheduling.
