Yes. Full offline mode – complete job sheets, photos, signatures and time logs offline. Syncs back when on signal.
Does it handle F-Gas and refrigerant logging?
You can attach F-Gas certificates, refrigerant usage logs and any PDF or photo to a job. Onsite Pro keeps them linked to the equipment and customer for audit.
How does it work for an HVAC team?
Office staff log in to the dashboard (£70/admin/month) and engineers use the iOS or Android app (£15/engineer/month). Dispatch installers and service techs separately.

CSV exports for QuickBooks, Xero, Sage or Zoho today. Direct integrations are on the roadmap.
