Best overall: Altora
Altora is purpose-built for contractor and employee onboarding, site check-ins, and compliance management. Unlike other platforms, there’s no app to download; contractors, employees and visitors can check in directly via a kiosk or using their personal device. Admins receive real-time alerts, and can easily access who-is-on-site reports.
Check-in requirements can be customised on a per-site or per-role basis, allowing you to restrict site access unless compliance requirements are met, such as up-to-date inductions or valid licenses. This reduces admin overhead and improves safety outcomes.
If you’re looking for an all-in-one system that balances power with simplicity, and scales without surprise costs, Altora is hard to beat.
Best for Visitor Management: Sine
Sine is a feature-rich visitor and contractor check-in system aimed at larger organisations. It supports custom visitor flows, pre-registration, and real-time notifications. However, Sine relies on a mobile app for many of its features, which can be a barrier to adoption on certain sites.
While Sine offers integration options and workflow automation, compliance handling requires manual setup or third-party systems, and monthly check-in limits can be restrictive for growing businesses.
Best for High-risk contractor management: Cm3 Onsite
Cm3 Onsite is part of a broader compliance ecosystem focused on contractor pre-qualification. It’s ideal for businesses in high-risk industries where complex document validation is essential.
However, Cm3’s strength in compliance comes with increased complexity, and its pricing model is typically customised based on contractor numbers and Business Risk Profile, making it less suited to agile or growing teams.
Conclusion
Why Altora is the smart choice
If your business needs:
A cost-effective solution without per-user fees or monthly check-in limits
Customisable, compliance-first check-in flows
A web-based system that works on any device

Scalable pricing across multiple or remote worksites
…then Altora is the clear winner.
