Service Fusion

Service Fusion is field service management (FSM) software for home-service contractors - HVAC, plumbing, electrical, appliance repair, and similar trades. It covers customer management, estimates, scheduling and dispatch, work orders/jobs, invoicing, payments, inventory, and a technician mobile app, with flat-rate pricing and unlimited users on every plan. Service Fusion exposes an Open API - a REST/JSON interface secured with OAuth 2.0 (base https://api.servicefusion.com/v1, token endpoint https://api.servicefusion.com/oauth/access_token) - that lets developers read and create records for customers, jobs, estimates, invoices, technicians, and related resources. API access is available on the Pro plan; the API is rate limited to roughly 60 requests per minute.
