Contractor Safety Management Software Models Are Becoming Increasingly Nuanced

A range of vendors offer centralized digital platforms that enable firms to manage contractor safety across the full life cycle of an operation or project. These solutions help organizations minimize contractor-related risks and deliver significant safety, operational and compliance benefits – particularly for firms with large or highly variable temporary workforces (see Verdantix Smart Innovators: Contractor Safety Management (2025)). There are two main approaches used to manage contractor safety, reflecting different ways of allocating costs and responsibilities: the ‘one-to-many’ framework and the ‘many-to-many’ framework.

Under a ‘one-to-many’ framework, a hiring client uses software to manage the safety qualification of each of their contractors from scratch. The hiring clients directly pays all the costs for the software, which is usually based on total user numbers. There is some variation among vendors on how they define a user, but generally the implication is that the hiring client’s software costs increase as contractors are added to the system. This framework has scalability issues for hiring clients as their contractor workforce enlarges, and for contractors who must re-upload their safety documentation each time they start work with a new client. To mitigate cost pressures as contractor workforces scale, some vendors reduce per-contractor pricing by limiting user functionality and interface access for contractors.

In contrast, the ‘many-to-many’ framework is, in theory, more scalable. Both hiring clients and contractors pay a membership fee to access a shared database, allowing contractors to upload and maintain their safety information once rather than repeatedly for each client. This model gives hiring clients immediate access to a pool of pre-qualified contractors, while contractors gain greater visibility, using verified safety credentials as a differentiator to attract hiring clients. There are various organizations that provide these databases, such as Avetta, EHA Soft Solutions, ISN, Twind by CTAIMA and Veriforce.

In practice, contractors may not be willing to incur additional costs of joining a many-to-many database. As a result, many pass these membership costs back to the hiring client on a project-by-project basis. This reintroduces a per-contractor cost dynamic, meaning hiring clients fail to realize the intended scalability benefits of the many-to-many approach. Moreover, contractors’ attempts to recoup costs results in challenging internal discussions for hiring client firms, as multiple stakeholders scrutinize how these expenses are justified.

To overcome contractors’ reluctance to join many-to-many platforms, vendors are increasingly rethinking traditional pricing models to lower barriers to entry and allow contractors to experience value before incurring significant costs. For example, Twind offers complimentary access for contractors working with their first hiring client, only charging fees when contractors expand usage to multiple clients or opt for additional functionality, such as access logs and subcontractor management tools. In parallel, contractors are more likely to engage with these platforms when business development features are strengthened and the commercial value of participation – such as increased visibility to hiring clients – is more clearly communicated.
