BigChange review
Bottom line
BigChange is a UK-focused field service platform that combines scheduling, mobile job sheets, CRM and invoicing with an AI layer that automates admin. Its clearest strength is how far it takes the job from booking to paid invoice inside one system, with offline mobile work and Xero or Sage sync. The main cost to watch is that pricing is provided on request and no free trial or free plan is published, so budgets need to be confirmed before committing. It suits UK trade and facilities businesses with mobile engineer teams that want to cut office admin.
What is BigChange?
BigChange is job management software built for UK field service businesses, including plumbing and HVAC firms, fire and security companies, facilities managers and electrical contractors. It brings jobs, scheduling, customer records, fleet tracking and invoicing into one platform. Field teams that once relied on spreadsheets, paper job sheets and separate systems can move work from booking through to payment in a single place.
Day to day, the office books a job and drags it onto an engineer's schedule, and the change reaches the engineer's mobile app within seconds. Engineers see their schedule and job histories, capture photos and signatures before, during and after work, and complete job sheets and risk assessments on their phones. The app works offline, and updates sync once the device reconnects. Completed jobs can be invoiced with detailed breakdowns of time and parts, then sent to customers. Customers receive SMS or email confirmations and a tracking link showing the engineer's arrival. Scheduling recalculates routes, and recurring preventative maintenance work can be generated automatically at set intervals.
The platform serves small, mid-sized and enterprise field service businesses, and the company reports more than 2,200 customers. Pricing is provided on request, and no free plan or free trial is published. Invoicing integrates with Xero and Sage, and card payments on site are available through BigChange Pay as an optional add-on.
What sets BigChange apart is Lightning, a set of AI features built into the platform. JustAsk lets managers ask questions about jobs, margins, schedules and customers in plain English. Other agents brief engineers before each visit using job history and site notes, capture on-site documentation from spoken observations, and send post-job summaries to customers automatically. GPS Time Tracking prompts engineers on arrival and departure and checks timesheets against location data. Many field service tools stop at scheduling and invoicing, while BigChange extends into documentation, customer messaging and time verification.
