simPRO API

simPRO is a cloud field service management platform that runs job management, scheduling, estimating and quoting, inventory, asset maintenance, and invoicing for trade and contracting businesses. A unified API lets you programmatically pull jobs, quotes, invoices, customers, schedules, assets, and catalog items—and push updates like new jobs, quotes, payments, and contractor records back into simPRO.

What is simPRO?

simPRO is a cloud-first field service management platform built for trade contractors and service businesses—electrical, plumbing, HVAC, security, and fire protection. Companies use simPRO Premium to manage the full job lifecycle: estimating and quoting, scheduling and dispatch, mobile field execution, stock and inventory control, asset maintenance, project tracking with progress and milestone billing, and invoicing and financial reporting.

Core product areas include:

  • Job and project management (jobs, quotes, leads, cost centers, variations, progress billing)
  • Estimating and quoting with catalog items, prebuilds, and takeoffs
  • Scheduling and dispatch with mobile field apps for technicians
  • Stock control, inventory, and vendor purchase orders
  • Asset maintenance, Maintenance Planner, and recurring service jobs
  • Invoicing, payments, credit notes, and financial reporting

Common data entities:

  • Jobs, Quotes, Leads, Job Sections, Cost Centers, Variations
  • Invoices, Credit Notes, Customer Payments, Contractor Invoices
  • Customers, Contacts, Sites, Employees, Contractors, Vendors
  • Activities, Activity Schedules, Assets, Asset Types, Plant & Equipment
  • Catalog Items, Prebuilds, Stock, Purchase Orders, Receipts

The simPRO Integration Challenge

Trade and contracting businesses run daily operations on simPRO, but turning its field-and-office workflows into reliable API-driven automation is non-trivial:

  • Per-company builds: Each simPRO Premium instance is a separate company build with its own URL, cost centers, and configuration—generic integrations break across tenants
  • OAuth2 and access setup: API access requires registering an application and configuring OAuth2 credentials and scopes per company build
  • Mobile-first field data: Time, photos, job notes, and payments are captured in the technician mobile app, scattering data that needs to be consolidated
  • Deep entity graph: Jobs link to sections, cost centers, catalog items, prebuilds, schedules, and invoices—pulling a complete record means traversing many related endpoints
  • Rate limits and pagination: High-volume reads across jobs, schedules, and catalog must respect API throttling and paginate carefully
  • Module variability: Endpoint coverage shifts with the modules a company licenses—Maintenance Planner, Digital Forms, Takeoffs, and GPS each add their own objects
  • Accounting sync nuances: Invoices, payments, and chart-of-accounts mappings require careful tax-code and reason handling to stay reconciled

How Supergood Creates simPRO APIs

Supergood combines simPRO's RESTful OAuth2 API with reverse-engineered authenticated browser flows to deliver a resilient, normalized API layer for your simPRO company build—covering job management, quoting, scheduling, inventory, and billing.

  • Handles OAuth2 application credentials and MFA-protected logins securely in a managed session
  • Maintains session continuity with automated token refresh and change detection
  • Normalizes responses across Jobs, Quotes, Invoices, Schedules, Customers, and Assets so you integrate once and rely on consistent objects
  • Aligns with each company build's cost centers, custom fields, and licensed modules to ensure complete, compliant access

Frequently asked questions

Both. Supergood uses simPRO's RESTful OAuth2 API where it exposes the data you need, and supplements it with authenticated browser flows for workflows and fields the public API doesn't cover—presenting a single normalized surface.

Supergood works with your existing simPRO Premium company build and credentials. We handle OAuth2 application registration and token management for you, so you don't have to build and maintain the auth layer yourself.

Yes. Time entries, job notes, photos, and field-captured payments flow through the same normalized API surface, so mobile field data sits alongside office job, quote, and invoice records.

Each company build is profiled against its licensed modules. Supergood exposes the objects those modules add—maintenance schedules, digital forms, takeoffs, GPS—rather than forcing a generic schema that ignores them.

Yes. The API supports creating and updating jobs, quotes, invoices, payments, and contractor records, with idempotency and validation so writes stay consistent with your build's cost centers and tax codes.
