Looking for more than just job scheduling?
If you are looking for an alternative to BigChange, you are probably not searching for just another scheduling system.You are looking for software that helps your team work faster, gives your helpdesk better control, keeps site information organised, improves engineer productivity, and reduces the amount of manual chasing needed to close and invoice jobs.That is where Arez stands apart.Built for modern UK service businesses, Arez FieldIQ is especially well-suited to FM contractors who need tighter control across sites, documents, compliance, and live operations. Instead of relying on disconnected systems and manual handovers, Arez helps your whole workflow run in one direction.
1
Built for FM contractors
Facilities management is not simple field service.
FM teams deal with multiple sites, recurring compliance requirements, customer-specific rules, certificates, service history, engineer readiness, supplier coordination, and commercial pressure to close work quickly and correctly.
Arez FieldIQ is built for that reality.
It gives FM contractors a single platform for managing not just jobs, but the wider operational context that determines whether those jobs are properly scoped, properly documented, compliant, and ready to bill.
For growing FM firms, especially those in the £10 million to £20 million revenue bracket, that makes a real difference. You need software that adds control without adding layers of admin.

Smart AI Docs turns document overload into site intelligence
This is one of the clearest ways Arez stands apart.
Most FM businesses are overloaded with documents. EICRs, PAT records, gas certificates, fire alarm reports, emergency lighting certificates, asbestos documents, LOLER paperwork, RAMS, site access files, and engineer paperwork often arrive in bulk and have to be sorted manually.
That takes time, creates errors, and slows everything down.
With Smart AI Docs, your team can upload a large batch of documents and Arez will help identify what type of document each file is, which site it belongs to, where it should sit in the system, and how it should be stored for future use.
Over time, Arez builds an AI document map across the customer estate. Every upload makes the platform smarter, helping contractors reduce manual admin while building stronger site intelligence.

AI Helpdesk Assistant improves job intake
A lot of operational problems start before the engineer is even dispatched.
When the helpdesk receives incomplete or vague job information, the result is predictable: more chasing, confusion, poorly scoped jobs, and unsuccessful visits.
Arez FieldIQ includes an AI Helpdesk Assistant designed to reduce that friction at the start. It helps teams capture better information, guide job triage, reduce ambiguity, and pass cleaner job details into dispatch.
That means engineers arrive better prepared, jobs are easier to allocate correctly, and the office spends less time fixing preventable mistakes.

Compliance built into the flow of work
In FM, compliance is not separate from delivery. It is part of the delivery.
The right engineer needs the right credentials. The right documents need to be available. The right proof needs to come back from the site. And the final record needs to stand up later when a customer asks questions.
Arez FieldIQ helps bring compliance into the live workflow rather than leaving it scattered across inboxes, folders, and spreadsheets.
Jobs, documents, site records, engineer status, and proof of work sit closer together, making it easier to identify missing information before it becomes a problem.
5
Better visibility across sites, jobs, and history
FM contractors need more than a simple job list.
They need to understand what has happened at a site before, what documents already exist, what access notes apply, whether the engineer is suitable, and whether the job is likely to complete successfully the first time.
Arez gives teams stronger operational visibility across sites, jobs, and service history.
This helps dispatchers make better decisions, gives engineers more context before attending the site, and helps managers stay in control across multi-site customer accounts.
6
A mobile workflow that helps jobs come back complete
Field teams do not just need access on a phone. They need a workflow that helps the office receive a complete and usable job record.
With Arez, engineers can receive jobs in real time, update job status on site, upload photos and documents, complete forms and checklists, capture notes and signatures, and return proof of work instantly.
The real value is cleaner closeout. That means less chasing from the office, stronger compliance records, and faster billing.
7
From job raised to invoice ready
One of the biggest drains on FM operations happens after the work is technically complete.
The job may be done, but the admin is not. Notes need checking, photos need chasing, documents need matching, and compliance still needs confirming before finance can invoice.
Arez FieldIQ is designed to reduce that friction. Because jobs, documents, compliance, site history, and proof of work are connected, contractors can move from a raised job to an invoice-ready job far more smoothly.
That means faster closeout, cleaner records, and less burden on the back office.
