Simpro (simPRO) is field service management and project/business management software for the trades - electrical, plumbing, HVAC, security, fire, and other contractors. It covers the full workflow of estimating, quoting, job management, scheduling and dispatch, asset maintenance, inventory and catalog, purchasing, timesheets, and invoicing. The Simpro REST API v1.0 exposes these resources over HTTPS, but it is not a shared public API - each API runs on the customer's own Simpro Premium build (host https://your-build.simprosuite.com) and is authenticated with OAuth2 credentials provisioned by that build's administrator. Resources are nested under a company at /api/v1.0/companies/{companyID}/... where companyID is 0 on single-company builds.
