Vento vs BigChange
BigChange is a job management, scheduling and mobile-workforce platform. BigChange is strong on scheduling, vehicle tracking and managing a mobile field workforce. Vento focuses on the technical front end of the air-con job — heat-load, system design and proposals — rather than fleet and workforce logistics.
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. BigChange's exact features vary by plan and change over time — confirm current details on BigChange'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. We don't speak for BigChange's product — verify current capabilities directly.
Where Vento wins for air-con installers
- The engineering is built in — Manual J 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 BigChange 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 BigChange may suit you. If air conditioning is your business, Vento is built for exactly that.
