Field Ascend is generator and UPS maintenance software for U.S. contractors servicing standby generators, UPS systems, battery banks and critical power assets across commercial, industrial, healthcare and data center environments.
Schedule planned maintenance, dispatch emergency repairs, record readings in the field and keep asset history connected to customers, sites and billing workflows.
From $13/user/month. All core features included for U.S. service teams.

Generator and UPS maintenance software helps standby power contractors manage preventive maintenance, load bank testing, battery testing, emergency dispatch, work orders, technician readings, quotes and service history.
Standby power only proves itself the moment the grid fails, so missed preventive maintenance, an untested battery string or an overdue load bank test are risks a contractor cannot afford to lose track of. Critical-power clients expect documented service history and fast emergency response, not a maintenance program managed on memory.
Field Ascend tracks every generator, UPS and battery bank with its own service intervals and readings, automates the preventive maintenance schedule, and supports priority emergency dispatch. Technicians log runtime, fuel and test results offline, and findings convert into quotes for approved remedial work.
Standby power systems need scheduled service before failure becomes an emergency.
Create recurring schedules for inspections, oil changes, run tests and annual service work.
Technicians can capture runtime, oil pressure, coolant temperature, alarms, fuel levels and recommendations.
Critical power service needs reliable test records, battery status and clear follow-up actions.
Track UPS systems, battery strings, service notes, replacement cycles and test history.
Keep test visits, results, photos and recommendations attached to the asset and customer record.
When critical power assets fail, office teams need fast dispatch and technicians need context.
