simPRO

simPRO is one of Australia's most established job management platforms, built specifically for trade and service businesses. Founded in Brisbane in 2002, it now serves over 24,000 businesses globally with a comprehensive end-to-end workflow covering quoting, scheduling, job costing, inventory, and invoicing. If your business handles complex commercial projects with multiple stages, simPRO is built for exactly that.

The platform has a public API with reasonable coverage, but there are friction points. Rate limits are adequate for typical use but will slow down bulk data syncs. Webhooks exist but have a reputation for inconsistent delivery. Documentation is functional rather than polished, and developer support is slow. Your integrator will need to be comfortable figuring things out independently.

The company itself is in strong shape. It's PE-backed with a billion-dollar-plus valuation, has made four strategic acquisitions since 2021, and established a new North American headquarters in Miami with plans to hire 500+ staff. Under new CEO Fred Voccola (appointed October 2025), simPRO is pushing hard into AI with its Delight acquisition in early 2026. The main things to watch are opaque pricing with long-term contract lock-in, and a user interface that divides opinion. For medium-to-large trade businesses that need serious project management capability, simPRO is a solid choice if you can stomach the onboarding investment.

simPRO was founded in 2002 in Brisbane, Australia by Stephen Bradshaw (an electrical contractor) and Vaughan McKillop (a software engineer). Bradshaw built the product because he couldn't find existing software capable of managing his contracting business. The company has been operating for over 23 years, making it one of the longest-running players in the trades software space.

The company is privately held and PE-backed. K1 Investment Management took a majority stake in 2021 with a $350M+ investment that valued simPRO at over $1 billion. Since then, simPRO has acquired AroFlo (Australian job management), ClockShark (US time-sheeting), BigChange (UK field service management), and Delight (AI-driven customer engagement), expanding from a single-product company to a five-brand group. Revenue is estimated at around $147M annually.

The company now employs roughly 600-700 people across offices in Australia, the US, UK, New Zealand, and the Netherlands. It serves over 24,000 businesses with 431,000+ users globally. Fred Voccola, former CEO of Kaseya, was appointed as Chairman and CEO in October 2025, and has established a new North American headquarters in Miami with plans to hire 500+ staff to drive the company's AI-first platform strategy. All indicators point to a company that will be around for the long haul.

simPRO is a cloud-based job management platform designed for trade and service businesses. It covers the full job lifecycle from lead capture and quoting through to scheduling, dispatching, job costing, inventory management, purchasing, invoicing, and payment collection. The platform is particularly strong for businesses handling complex commercial projects with multiple cost centres and stages.

Core functionality includes estimating and quoting tools, drag-and-drop scheduling with field technician dispatch, real-time job tracking and costing, inventory and stock management, purchase ordering, timesheet capture via mobile app, customer and site management, and integrated invoicing with accounting sync. The mobile app lets field staff access job details, capture time, complete forms, and update job status from site.

The primary target market is small-to-medium commercial trade businesses in electrical, plumbing, HVAC, security, fire protection, and building maintenance. The sweet spot is businesses with 20-50 employees running complex commercial projects, though it scales from small teams up to enterprise operations.

simPRO does not publish pricing publicly. All pricing is quote-based and depends on user count, selected modules, and onboarding requirements. Third-party estimates suggest a base of around $30 per user per month, with small teams (1-5 users) typically paying $150-300 per month and mid-sized operations (10-25 users) in the $600-1,500 range.

There is no free tier and no free trial. Onboarding involves an upfront fee covering training, data migration, and configuration that can run into the thousands. Add-on modules for maintenance planning, digital forms, GPS tracking, and SMS increase the monthly cost further. Priority support is also an additional charge.

Contracts are typically multi-year (3 or 5 years) with annual price increases locked in at CPI plus a margin. Users have reported being locked to minimum user quantities, with significant penalties for early contract exit. This is worth understanding clearly before signing.

simPRO offers a REST API available to Premium plan customers. The API covers most major entities including contacts, customers, jobs, quotes, leads, invoices, inventory, schedules, and reporting. A downloadable API specification is available, and there's a developer portal with documentation and code examples.

Rate limits sit at 10 calls per second, which is adequate for typical integration scenarios like syncing new jobs or pushing invoice data. For bulk operations like migrating historical data or running large reconciliation syncs, you'll need to build in queuing and throttling logic. The limits were tightened in April 2025, so older integration guides may reference more generous allowances.

The API has been around since at least 2012, so it's reasonably mature. That said, developer feedback is mixed. Some endpoints have inconsistencies, response times can be slow for complex queries, and the developer forum is only monitored weekly by simPRO staff. Your integrator should expect to spend some time figuring things out rather than finding ready-made answers in the documentation.

You can export data from simPRO through the web interface with options for CSV files across different data areas. Asset and catalogue data can also be exported in bulk. The API provides programmatic access to all major entities for custom extraction.

The main constraint on API-based export is the rate limit, which means extracting a large dataset will take time and planning. There is no single 'export everything' function, so you'll need to pull data section by section. Getting your data out is achievable but requires effort, especially for larger businesses with years of historical job data.

The bigger lock-in concern is contractual rather than technical. Multi-year contracts with exit penalties mean you may be paying for simPRO long after you've decided to move, even if your data is already extracted.

The developer portal provides API documentation, code examples in multiple languages, and a downloadable API specification you can use with tools like Postman. There's a dedicated API forum where developers can ask questions and report issues.

The reality is mixed. Documentation exists but is not always easy to navigate, and some developers report it feels incomplete in places. The forum is the main support channel but is only monitored weekly, so don't expect quick turnarounds on technical questions. Sandbox environments are available on request rather than self-service.

Developers who have worked with the API report it as functional but rougher around the edges compared to platforms like Xero. Slow response times on some endpoints, occasional data issues from update requests, and webhook unreliability are recurring themes. An experienced developer will get the job done, but it takes more effort than best-in-class platforms.

Vendor lock-in risk with simPRO is moderate-to-high, and it's more contractual than technical. On the technical side, data can be exported via CSV or API, so you can get your information out with enough effort. The rate limits mean bulk extraction takes time, but it's achievable.

The real lock-in is in the contract terms. Multi-year agreements with minimum user commitments, annual price increases, and significant exit penalties mean walking away has a financial cost even if you've already migrated your data elsewhere. The extensive onboarding investment (training, configuration, workflow customisation) also creates switching costs, as your team will have invested weeks learning the platform.

Before signing, make sure you understand exactly what you're committing to for the contract term, what it costs to exit early, and whether user minimums match your actual needs.

Webhooks can be configured through the UI or API and cover events like job and invoice creation and updates. However, reliability is a known concern. Multiple developer forum threads report webhooks not firing consistently. There does not appear to be signature verification for validating webhook payloads, so your integrator will need to build their own validation.

simPRO is a serious job management platform for serious trade businesses. If you're running a commercial electrical, plumbing, HVAC, or maintenance operation with 20+ staff and complex multi-stage projects, simPRO has the depth of functionality to manage the full lifecycle from quote to payment. The company has been around for over two decades, has strong financial backing, and is actively growing.

The trade-offs are real though. You'll invest significantly in onboarding and training before seeing returns. The pricing is opaque, contracts are long-term with escalation clauses, and exiting early is expensive. The user interface has a steep learning curve that frustrates some teams. And if you're planning custom integrations, expect the API to be functional but not friction-free.

This is a good fit for medium-to-large trade businesses that need comprehensive project management and are willing to invest in getting the system set up properly. It's not a good fit for small operations, sole traders, or businesses that want something they can set up over a weekend. For simpler needs, look at ServiceM8, Tradify, or Fergus instead.

simPRO does not appear to hold SOC 2 or ISO 27001 certifications, which is a notable gap for a platform handling sensitive business and financial data for hundreds of thousands of users. The company hosts on AWS and claims GDPR compliance with a dedicated team and published data protection policy. They maintain a Notifiable Data Breaches page under the Australian NDB scheme but have no publicly disclosed incidents. The absence of independent security certifications means you're taking the company's word for their security posture rather than having third-party verification.
