Our verdict on OpenFieldService

OpenFieldService is an open-source field service management application for plumbing and other service businesses, including HVAC, pest control, cleaning, landscaping, and electrical work. It is aimed at developers and operators who want a self-hosted foundation for scheduling jobs, assigning technicians, managing customers and equipment, generating invoices, and tracking materials. The web, API, and self-hosted deployment model keeps the product focused on core operational records rather than a packaged software suite.

Its feature set covers the main workflow from dispatch to job history. Teams can schedule work with dates, times, priorities, and statuses, review technician schedules in a weekly visual calendar, track workloads and availability, and use job checklists, notes, and activity logs. Customer records include contact details, addresses, service history, and notes, while customer sites and equipment records preserve service context. Configurable service types can include default prices and durations, and the system supports invoice generation, invoice status tracking, materials, and inventory. The REST API covers jobs, customers, technicians, materials, and invoices, giving developers a defined route for integrations and automation.

OpenFieldService suits organizations that can manage infrastructure and want control over a minimal operational base. The application runs locally or on infrastructure controlled by the operator and uses SQLite-compatible storage, so deployment and ongoing administration remain part of the ownership model. It is less suitable for teams seeking a ready-made mobile workflow, built-in online booking, estimates, payments, or a broad set of prebuilt integrations. The license position also deserves attention before redistribution, because the published materials show AGPL-3.0 and MIT terms. Choose it for an adaptable self-hosted core; choose another product if packaged field-service features are the priority.
