Interim

Hire an interim financial controller for a defined job

Interims suit work with an end date.

Hire an interim financial controller for a vacancy, an audit or a system change. For ongoing part-week cover, a fractional controller suits better.

Agree the end before the start: the handover is part of the assignment.

The working pattern

What changes when the financial controller is interim?

An interim financial controller works full-time for a defined period, usually covering a vacancy or delivering a specific change such as a system migration or an audit.

The illustrative brief: a controller leaving before year-end. The controller resigns two months before the audit.

The appointment owns: An interim financial controller runs year-end and the audit, then hands over.

Another owner retains: The FD signs the accounts; the auditor’s scope is unchanged.

The case is illustrative; it does not describe a Fractional Quest placement.

Assessment

How should you assess each candidate?

Hire an Interim Financial Controller on evidence: put the same work in front of each candidate before comparing answers.

  1. Comparable work
    Ask for a year-end or migration they ran as an interim.
  2. Authority
    Test an adjustment a director wants.
  3. Team
    Ask how they led an inherited team.
  4. Handover
    Ask how they handed over.

Acas recommends a consistent, fair selection process: choosing who to interview.

Vetting

What happens before anyone reaches your shortlist?

Five stages before a candidate reaches a shortlist of three to five.

  1. Pedigree screen
    Tenure
    We verify prior tenure in the seat, at the scale and stage you need. No consultant presenting as an executive.
  2. Mandate fit
    Fit
    Fit to your stage, sector and the problem the seat exists to solve, not a CV keyword.
  3. Reference deep-dive
    Verify
    We take references ourselves, from recent clients and boards: what they delivered, not what they titled it.
  4. Shortlist
    Shortlist
    Three to five candidates, each with day rate, availability and IR35 position set out.
  5. Kick-off
    Start
    Scope, first-month outcomes and the contract agreed before day one.

The full process is on how we vet.

The right pattern

Does this hiring pattern fit the work?

Test the amount of the week, the expected end and the continuity needed before writing the contract.
