Your accounting manager just resigned. Month-end is in nine days. The audit starts in six weeks. Someone suggests posting the job. Someone else suggests calling a contractor. Both are reasonable, and one of them is wrong for your situation.
As a CFO I made this call more times than I would have liked. Here is the framework I used, and still use when advising clients.
Start with the shape of the gap, not the title
The instinct is to replace the title that left. That is often a mistake. Ask instead: what work is now not getting done, and for how long?
- Time-bound work: a close that must happen, an audit that must be fed, a migration that must finish.
- Ongoing work: the daily operation of a function that will exist as long as the business does.
- Project work: a defined deliverable with an end, such as a revenue-recognition implementation or a clean-up of eighteen months of unreconciled accounts.
Time-bound and project work point to interim. Ongoing work points to a permanent hire. Most real situations are a mix, which is why so many companies end up doing both.
When interim is the right call
You need someone in the seat within days. A good direct-hire search for a controller or accounting manager takes weeks to run properly and weeks more for notice periods. If the work cannot wait, an interim professional who has done exactly this before is the only honest answer.
The scope is a deliverable. "Get us through the audit." "Migrate us off QuickBooks." "Reconcile the balance sheet and tell me what is wrong." These are projects. Hiring a permanent employee for a project leaves you with a permanent employee and no project.
You are not sure what the permanent role should be. After a departure, the honest answer is often "we do not know yet what we need." An interim professional stabilizes the function and gives you a clear view of the real job before you write the job description.
The business is changing. An acquisition, a financing, a system change, or a leadership transition all shift what the finance team needs to look like. Committing to a permanent hire mid-change locks in assumptions that may not survive.
When direct hire is the right call
The role is core and stable. If the position will exist in the same form in three years, you want someone who will be there in three years. Interim professionals are excellent at what they do, but they are not building a career inside your company.
Institutional knowledge matters. Some roles accumulate value over time: the person who knows every customer contract, every intercompany quirk, every reason the numbers look the way they do. That knowledge walks out the door with a contractor.
You are building a team, not filling a slot. A permanent accounting manager develops staff accountants. A permanent controller builds a function. Interim professionals can hold a team together, but sustained development needs a permanent leader.
The hybrid most companies actually need
The most common right answer is: interim now, permanent search in parallel. The interim professional keeps the close on schedule and the audit fed. The permanent search runs without the pressure to settle for the first plausible candidate. If the interim professional turns out to be the right permanent fit, contract-to-hire lets you convert without starting over.
The failure mode to avoid is the opposite: post the permanent job, wait for applicants, interview under pressure, hire whoever is available, and discover in month four that they cannot do the job. That costs far more than an interim engagement would have.
Questions that resolve most cases
- If this work does not get done in the next thirty days, what breaks?
- Will this role look the same in three years?
- Do we actually know what we need, or do we need to stabilize first and find out?
- Who on our team can technically evaluate a candidate for this role, and how much of their time do we have?
If the first answer is "something serious," go interim now. If the second answer is "yes," run a permanent search. If the third answer is "we are not sure," go interim first. And if the fourth answer is "nobody," get help with the screening before you hire anyone at all.
A note on cost
Interim rates look expensive per hour. The comparison that matters is total cost of the gap: late closes, audit overruns, missed covenant reporting, a bad permanent hire, and the management time consumed by all of it. Priced against that, a well-scoped interim engagement is usually the cheaper option. A poorly scoped one is not, which is why the scope should be written down before anyone starts.
