description: 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.
