Muster vs BigChange: Feature Comparison for UK Trade Businesses
Muster and BigChange are both job management platforms for UK trade businesses, but they differ significantly in pricing, contracts, and approach. BigChange is an established fleet management and field service platform that typically requires 3–5 year contracts at £40–80/user/month plus implementation fees of £5,000–15,000. Muster is an AI-native platform starting at £179/month on a monthly rolling contract with no lock-in, offering AI receptionist, RAMS generation, training management, and Pay by Bank — features BigChange lacks.

Muster vs
BigChange
BigChange is a powerful fleet and job management platform — but it locks you into a 5-year contract with hidden pricing that's hard to downgrade. Muster gives you AI-first job management with compliance, training and FM built in. From £179/month, monthly rolling.
BigChange
Best for: Large field service companies (50+ staff) who prioritise fleet management over trade-specific workflows.
- Strong vehicle tracking with bundled hardware
- Job management & scheduling
- Complex setup, steep learning curve
- 5-year contracts, hidden pricing, hard to cancel
Muster
Best for: UK trade crews (3–60+ people) who need AI, compliance, training and FM — without the complexity or contract lock-in.
- AI receptionist, bid writer, call intelligence
- RAMS, training, CIS, cert tracking built-in
- From £179/month, monthly rolling, transparent pricing

Pricing
Transparent vs “call for a quote”
Muster publishes every price online. BigChange requires a sales call and locks you into a 5-year contract that reviewers say is difficult to downgrade or cancel.
BC BigChange
Based on publicly available Trustpilot reviews — BigChange does not publish pricing.

Common frustrations
When BigChange doesn't fit
BigChange has been around since 2013 and does a lot. But “does a lot” often means “takes a lot to set up and costs a lot to run.”
5-year contracts
One of the longest lock-ins in the industry. Multiple Trustpilot reviewers report being unable to downgrade or cancel. You're committed before you've finished onboarding.
Hidden pricing that creeps up
No public pricing — you only find out costs after a sales call. Reviewers report unclear pricing changes, extra charges not explained during the sale, and features locked behind paywalls.
Complex and slow to set up
One customer reported 13 months of onboarding without finishing. "Everything is manual or difficult" — editing worksheets, reporting, managing crew, filtering data.
No AI capabilities
No AI receptionist, no bid writer, no call transcription. They have an AI dashcam add-on, but no AI in the core platform. Still relies on manual processes.
Payments only recently added
Payments is labelled "New" on their site. No Apple Pay, no Pay by Bank. Muster has had branded checkout with Open Banking since day one.
Training and compliance gaps
No toolbox talks, video courses, or quiz tracking for your field team. No built-in RAMS generation. RAMS and training are core to Muster, not an afterthought.
Muster's approach
Same power for trade businesses, without the complexity or commitment.
Honest take: who should use what
We're not the right fit for everyone. Here's our honest view.
BigChange might be better if you…
- Run 100+ vehicles and fleet management is your main concern
- Need deep customisation and have dedicated IT staff to manage setup
- Are happy committing to a 5-year contract upfront
- Require ISO 27001 certified infrastructure today (BigChange has this; Muster certification in progress)
Muster is better if you…
- Want AI to answer calls, write bids, and automate admin
- Need RAMS, training, toolbox talks and compliance built-in
- Want transparent pricing and no 5-year lock-in
- Run a UK trade business (3–60 crew) and need to scale without complexity
- Want customers to pay via Apple Pay, Pay by Bank, or branded checkout
