Who Commusoft is genuinely built for

Commusoft is a mature UK field service platform, and the honest starting point is that it is very good at what it is built for. Its design centre is dispatch: getting the right engineer to the right job across a live schedule, then holding the customer relationship around that. The office side runs scheduling, job costing, quoting and CRM; the field side adds a mobile app, stock control, digital forms and asset and fleet tracking; the customer side layers on service contracts, portals and an AI assistant it calls AI:den. Commusoft reports supporting more than 10,000 pros, with over 2.1 million jobs completed and more than £1 billion in invoices sent through the platform in 2025.

Compliance is native, not an afterthought. Commusoft produces CP12 gas safety records and electrical certificates including EICR, Minor Works and PAT, with offline creation on mobile, auto-populated fields and digital signatures. The catch for smaller firms is not the feature set, it is who it is aimed at. Commusoft’s own booking page states plainly that the platform is specifically designed for businesses with 6 or more staff. That is a fair line to draw. It just means the product assumes a scale a lot of trade businesses have not reached, or do not want.

Why smaller and mid-size trades move on

Nothing above makes Commusoft the wrong tool. It makes it a tool with a floor. Three specifics push firms under, or near, that floor to shortlist something else.

You cannot see a price. Commusoft’s request-pricing page redirects to a book a call form with no tiers and no starting figure, so comparing cost means sitting through a sales call first. Third-party listings put the entry point at around £40 per licence per month, but that is an outside estimate, not a number Commusoft stands behind on its own site.

The commitment is a year. Commusoft’s core plans lock in on a 12-month term that renews annually. Monthly and daily licences for seasonal staff and subcontractors add flexibility, but sit on top of that annual commitment rather than replacing it. A firm that has not proven the software fits its week is signing up for a year to find out. Joblogic sits in similar territory, its Standard plan at £45 per user per month billed annually (our Joblogic alternative guide covers that case).

The six-staff assumption. A sole trader, a two-hander, or a firm growing toward that mark is, on Commusoft’s own framing, outside the segment the product is designed for. For the wider field of tools built for that smaller scale, our roundup of job management apps for UK tradespeople compares eight side by side.

Commusoft alternatives compared

Here is how Commusoft and four commonly shortlisted alternatives line up on what a small or mid-size UK trade business actually decides on. It is a fair shortlist, not a ranking: each wins for a different size and shape of business.

Software	Best for	UK compliance certificates	Pricing and contract
Commusoft	Established multi-engineer plumbing, heating, gas and electrical firms	Native: CP12 gas, EICR, Minor Works, PAT	Quote or demo only, no self-serve figure; 12-month contract, designed for 6+ staff
Checker	1 to 15 person compliance heavy trades (gas, electrical, plumbing, heating)	Native: CP12 gas, electrical certificates	Per sub-user: Lite £10.99, Pro £19.99, Pro Plus £25.99/month plus VAT, no lock-in
Tradify	General multi-trade job management	Electrical native from Pro tier up; gas coverage not confirmed	£34 to £44/user/month (UK); no offline mode
Joblogic	Commercial and compliance-heavy contractors	Certification modules included	£45/user/month annual (Standard); monthly rolling available; Premium/Enterprise quote-only
ServiceM8	Small, mobile-first trade businesses	Not confirmed; general custom form builder (250+ templates)	Free to £269/month by job volume, ex VAT, no contracts

Read it this way. Past six staff with a dispatch board to run, Commusoft’s depth is proportionate, and Joblogic is the other name in that bracket. Doing compliance-led gas and electrical work at a smaller scale and wanting certificates plus automated chasing without a year-long tie-in, Checker fits at £10.99 to £25.99 per sub-user a month plus VAT. Tradify handles general job management well for teams with reliable signal, but has no offline mode and gates electrical certificates to Pro (our Tradify alternatives guide unpacks that). ServiceM8 suits the simplest mobile-first setups that do not need named UK templates.

Checker in depth

Checker (built by Gassoft Limited) is the tool most 1 to 15 person compliance firms land on when Commusoft’s size assumption and annual contract feel a size too big. There is no six-staff floor and no lock-in. Pricing is per sub-user, Lite at £10.99 a month, Pro at £19.99 and Pro Plus at £25.99, all plus VAT, billed month to month, with master-user controls over what each team member can see. Close to 19,600 UK trade users are on it now, and it has produced 6.88 million gas compliance reports to date.

Compliance sits at the centre of the product, not as a module you switch on. Gas and electrical certificates, CP12 landlord gas safety records among them, generate from the same job and customer record as the quote and invoice, so nobody keys a postcode or boiler serial twice and nothing is exported to a second tool.

Where Checker earns its place against a heavier dispatch platform is the repeat-business side. Its Growth Engine runs four automations, all sent under the firm’s own email and logo so customers hear from their engineer, not from software:

• Appointment Reminders go out 24 hours before a booked job by default, with timing, wording and channel all editable.
• Quote Chaser follows an unanswered quote up to three times, default day 7, 10 and 14, tone escalating, with a one-click Accept Quote button.
• Invoice Chaser starts the moment payment terms lapse, up to three toggleable reminders that stop dead the second the invoice is paid. With 81% of UK tradespeople chasing late payments, an average £6,210 outstanding and 86 hours a year lost, that one automation pays for itself.
• Annual Service Reminder fires 11 months after a customer record is created, turning last year’s job into next year’s booking. That timer counts from record creation, not the certificate’s legal expiry, so on older records check the date lines up before you lean on it.

The honest limit is the mirror image of Commusoft’s strength. Checker is not a multi-depot, fleet-tracking dispatch system and does not pretend to be. A firm running vans and engineers at Commusoft’s scale needs that depth. A compliance-led gas, electrical, plumbing or heating firm of 1 to 15 people usually does not, and only pays for it if it buys it.

Switching off Commusoft

Leaving Commusoft is a different job from leaving a lightweight app, because it holds more of the business in one place. Four things are worth planning for.

• Map the data model before you export. Commusoft stores customers, full job history, asset records and, for many firms, service contracts and planned maintenance schedules. Decide which the new tool actually has to carry. A firm stepping down from dispatch scale often does not need to recreate asset registers or PPM contracts, which shortens the migration.
• Protect certificate history. Export your completed CP12 and electrical certificates and confirm they stay retrievable for audit. Landlords must produce gas safety records going back at least two years, per HSE guidance, so do not close the Commusoft account until you hold those copies.
• Time the exit around the 12-month term. The core plan renews annually, so line the switch up with renewal and check what notice you owe. Any monthly or daily licences for temporary staff can be wound down separately.
• Right-size on purpose. Moving to a smaller tool means shedding fleet, dispatch and asset modules you were paying for. Below the six-staff mark, that is the point of the move, not a loss.

How to choose between them

Strip the shortlist back and four questions settle it for most compliance-led firms.

• Team size and stage. Six or more staff running a live dispatch board points to Commusoft or Joblogic. One to fifteen doing compliance work points to Checker, with ServiceM8 for the simplest mobile-first setups.
• Certificates. CP12 and electrical certificates should be native, not a bolt-on. Checker and Commusoft build them in; Tradify gates electrical certificates to Pro with gas unconfirmed; ServiceM8 offers a general form builder, not named UK templates.
• Contract and price transparency. To see the price before a sales call and skip a year-long tie-in, Checker’s published per sub-user pricing and monthly terms are the plainest here.
• Automation. Chasing quotes, invoices and annual services is where the unpaid hours hide. Checker’s Growth Engine bundles all three.

Who should stay with Commusoft

To be fair to Commusoft: an established plumbing, heating, gas or electrical firm with six or more staff, coordinating several engineers across several sites a day, gets real value from its dispatch board, service-contract management, customer portals and asset tracking. Its reported scale, more than 10,000 pros and over 2.1 million jobs completed in 2025, reflects genuine use at that size. If that is your operation, the leaner tools here would cost you capability you rely on. The move to a smaller-scale alternative pays off only when you are below, or not dependent on, that six-plus staff scale.
