Vento vs Onsite7
Onsite7 is job and project management software for construction and trade businesses. Onsite7 helps trade and construction teams manage jobs, documents and site paperwork. Vento adds the air-con engineering a general site tool doesn't — room-by-room sizing, 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. Onsite7's exact features vary by plan and change over time — confirm current details on Onsite7'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.

Projects and sites, not systems
Onsite7 is job and project management software for construction and trade businesses — the paperwork and co-ordination around site-based work: jobs, documents, people, progress. If your work is projects with phases and sub-contractors, that framing fits.
An air-conditioning install is a design before it is a project
Even on a construction job, the air-conditioning element has an engineering step that project software does not cover: how much cooling each space needs, what equipment meets it, where the pipework and condensers go, and what the refrigerant record will say afterwards.
Air-conditioning sizing and system design are not what Onsite7 advertises — confirm the current position with them. So on a mixed-trade site the sizing is usually done elsewhere and handed over as a number.
Vento produces that number and the drawing behind it, and keeps them attached to the job, which is what you want when someone asks six months later why that unit was specified. See everything Vento includes.
Where the two could sit together
On larger construction work it is entirely reasonable to run project management at the site level and Vento for the air-conditioning package inside it — the design, the equipment schedule, the commissioning and the F-Gas record.
If you are a specialist sub-contractor doing the air-conditioning package, Vento covers your side of it end to end, including Schedule of Rates pricing and batch billing if you work on measured contracts.
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 Onsite7 handle F-Gas and system design?
Refrigerant records and air-conditioning system design are not part of what Onsite7 advertises — it is job and project management for construction and trade businesses. Confirm the current position with them.
Does Vento handle contract and measured work?
Yes. You can import a Schedule of Rates — NHF, PSA or your own — measure against it, and batch-bill maintenance contracts, which is the shape most commercial and social-housing work takes.
Can Vento run alongside project software?
Yes, and on larger sites that is often the sensible arrangement: the project tool co-ordinates the site, Vento owns the air-conditioning package and its compliance record.
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 Onsite7 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 Onsite7 may suit you. If air conditioning is your business, Vento is built for exactly that.
