Schedule a meeting

Senior capacity for your Internal Audit function, whenever you need it.

Support where your Chief Audit Executive (CAE) needs it: co-sourcing during year-end peaks, specialist audits (IT, fraud, derivatives), setup or recalibration of the IA function, or vacancy cover. Senior specialists only (CIA · CISA · CFE · CRMA · RA · RE · RO), in your methodology, with you as the client.

// 01—Four modalities

Four modalities, one quality standard

Internal Audit Support is tailored: senior capacity on assignment, in your methodology and under the direction of your Chief Audit Executive. Four forms are most common in practice.
  1. 01

    Co-sourcing

    Additional senior capacity alongside your own team, for example during year-end peaks or a full audit plan. You keep the direction and the relationship with the audit committee; findings are reported under your name.
  2. 02

    Specialist audits

    Audits that require specific expertise, such as IT, fraud or derivatives. We provide the specialist with the right certification; the engagement stays within your audit plan and your methodology.
  3. 03

    Set-up or recalibration of the function

    Set-up of a new internal audit function or recalibration of an existing one: audit charter, audit universe, risk-based audit planning and the reporting lines to the board and the audit committee.
  4. 04

    Vacancy cover

    Cover during a vacancy: a senior on assignment for the duration of your recruitment. If the engagement runs beyond six months, we adjust the mandate to avoid de facto secondment.

Frequently asked questions

What does Internal Audit Support cover?

Support where your CAE needs it: co-sourcing during year-end peaks, specialist audits (IT, fraud, derivatives), setup or recalibration of the IA function, or vacancy cover.

Is co-sourcing labour secondment?

No. We set up co-sourcing as a contract for services under Article 7:400 of the Dutch Civil Code, without an authority relationship and without tacit renewal. Whether that holds depends on how the work is actually carried out, which we manage during the engagement.

What is the lead time for a senior match?

For internal audit roles we provide a match within two weeks, for specialist roles up to four weeks. We work with our own senior specialists and an established network of experienced freelancers, not with agencies.

Can I deploy a senior during a vacancy?

Yes. Vacancy cover is a core engagement: senior on assignment for the duration of your recruitment. Beyond six months we restructure the mandate to avoid de facto secondment.
