Vento vs ServiceM8
ServiceM8 is a job-management app for small trade and service businesses. ServiceM8 is a clean, lightweight app for quoting, scheduling and invoicing small jobs across trades. Vento adds the air-con engineering a lightweight general app doesn't — heat-load, capacity matching, scaled system drawings and refrigerant compliance.
The comparison below is at a category level: both handle the day-to-day admin of running a trade business, but only Vento is built around air-conditioning design and engineering. ServiceM8's exact features vary by plan and change over time — confirm current details on ServiceM8's website.

"Varies" means the capability exists in some form or depends on plan/integration. General field-service platforms cover many trades; air-con-specific engineering like room-by-room heat-load and refrigerant system design is not something they set out to do.

What ServiceM8 is built for
ServiceM8 is a job-management app for small trade and service businesses, and it is deliberately light. Quote, schedule, dispatch, invoice, take a card payment — the core of running jobs, on a phone, without a long implementation. For a sole trader or a two-van outfit that mainly needs the admin to stop living in a notebook, that restraint is the point, not a shortcoming.
It is also genuinely cross-trade. Plumbers, sparks, locksmiths and cleaners all run on it, which is why it stays general: anything specific to one trade would be dead weight for the other twenty.
Where a light app leaves the engineering
The lighter the tool, the more of the air-conditioning job happens outside it. Working out what each room actually needs, choosing equipment against that number rather than against habit, and putting a system layout in front of the customer — none of that is what a general job app sets out to do, and ServiceM8 does not advertise it. Worth confirming with them directly if you think otherwise.
In practice it means the sizing lives in a spreadsheet or in your head, and the quote gets typed up separately afterwards. That works until a job is questioned, or until the person who does the sizing is on holiday.
Vento starts at the survey instead. You measure the room, it calculates the load, you pick equipment against it, and the proposal comes out of that design rather than being re-keyed from it. See everything Vento includes.
What to ask before you commit to either
Ask ServiceM8 what their Android app does compared with their iOS one, if any of your engineers are on Android — the two are not always the same product, and the answer matters more than any feature list if half your team is on the wrong phone.
Ask both of us how support works when something breaks mid-job, and whether you can get a person rather than a queue.
Vento’s pricing is published and flat: plans start at £49 a month, with the Professional plan at £149 a month including 3 seats and extra seats at £25. Every plan has a 14-day free trial and there is no multi-year term to sign. See the full pricing for what each plan includes.
Frequently asked questions
Does ServiceM8 do heat-load calculations?
Room-by-room heat-load calculation is not something ServiceM8 advertises — it is a general job-management app rather than an air-conditioning design tool. Confirm the current position with them. If you install air conditioning regularly, the sizing has to happen somewhere, and doing it in the same place you raise the quote removes a re-keying step and a source of error.
Is Vento overkill for a one-man band?
Not necessarily — the Starter plan is a single seat. The question is whether you size systems. If you do, having the calculation, the design and the proposal in one place saves more time than a lighter tool does, because the lighter tool leaves the hardest part outside it.
Can I use both?
You can, and some installers do while they move across. The thing to watch is double entry: if the customer record lives in two systems, one of them goes stale, and it is usually the one you are not invoicing from.
Where Vento wins for air-con installers
- The engineering is built in — Room-by-room heat load, capacity matching and scaled system drawings are part of the workflow — not a separate CAD seat, spreadsheet or add-on a general tool can't provide.
- Purpose-built, not adapted — Vento only does air conditioning, so surveying, sizing, drawings and F-Gas fit how your jobs actually run — where ServiceM8 is built to serve many trades at once.
- Win the job on the visit — Survey, design, proposal, e-sign and deposit happen in one visit, so you leave with a signed job and money in the bank.
If you run several trades, a broad platform like ServiceM8 may suit you. If air conditioning is your business, Vento is built for exactly that.
