WTA-compliant hiring: Start with a single source of truth

The implementation of the Act on the Admission and Provision of Workers (Wtta) on January 1, 2027, will fundamentally change the way organizations hire external talent.

While compliance currently often relies on ad hoc checks and manual audits, the Wtta requires structural safeguards, continuous visibility, and the assurance that you’re working exclusively with authorized parties. This calls for tools that embed these measures into the process. At Olli, we help organizations both organize and automate compliant hiring. In this blog, we’ll walk you through how we put this into practice for our clients.

From scattered information to centralized management

In many organizations, information about suppliers is scattered throughout the system:

  • Contracts in a single system
  • Excel Certifications
  • Admission statuses appear in mailboxes or are missing entirely

This makes compliance vulnerable. This is especially true under the Wtta, where the responsibility also lies with the hiring company. Olli consolidates this information into a single platform that serves as the foundation for the hiring process.

Olli as the Single Source of Truth

Within Olli, there is one central location where the current status of suppliers is always up to date.

In concrete terms, this means:

  • A single overview of the approval statuses of all suppliers
  • An explicit Wtta status field within the supplier module
  • Automatic alerts when permits expire or are missing
  • Barriers to the participation of non-approved parties

This makes compliance a standard step in the process. It immediately prevents the initiation of a project with a party that does not meet the requirements.

Compliance that stays up to date

The Wtta requires up-to-date data, not snapshots. That is why Olli is being set up to systematically update supplier statuses. For example:

  • regular updates on admission data
  • links to external registries, such as the regulator’s future database
  • automatic validations within ongoing orders

This ensures that the status of suppliers remains transparent and accurate throughout the duration of contracts.

Transparency toward regulators

A key component of the Wtta is accountability. With Olli, transparency becomes part of our daily work:

  • transparent audit trails
  • documentation available immediately
  • clear reports on suppliers and orders

Organizations maintain a constant overview and can provide immediate evidence to support this when necessary.

Ready for 2027

The Wtta requires organizations to professionalize their hiring process. By embedding compliance into their tools, this results in:

  • lower risk
  • fewer mistakes
  • less manual work
  • greater confidence among stakeholders

In addition, it will become easier to scale up temporary staffing without adding extra complexity. Organizations that will soon be compliant with the Wtta have already set up and secured their processes in a timely manner. Olli helps with this by making compliance an integral part of daily operations.
