FAQ

Field service vs CMMS—which should I choose?

Field service is customer-site jobs and routing. CMMS is facility assets and preventive maintenance indoors.

Do technicians need offline mode?

Often yes. Prompt for local draft forms that sync when connectivity returns, then validate in preview.

How do invoices attach to jobs?

Store billable lines on completed jobs and push to invoicing via a shared customer and job ID.
