The real cost of a bad finance hire
When a finance hire doesn't work out, the number most businesses reach for is the recruitment fee or a few months' salary. The real cost runs much deeper than that, and it's worth being honest about the full picture before deciding a slightly cheaper, slightly quicker hiring process is actually saving you money.
Start with the direct costs: the salary paid during a notice or probation period that didn't deliver, the recruitment cost of doing the search twice, and — specific to transactional finance — the cost of errors that made it into the numbers before anyone noticed. A Purchase Ledger Clerk who's out of their depth doesn't just work slowly; they miscode invoices, miss payment runs, or let supplier statements drift unreconciled, and those errors often surface months later at the worst possible time, like year-end audit.
Then there's the cost that's harder to put a number on but usually bigger: what it does to the rest of the team. A finance team is small by nature, and one person not pulling their weight is felt immediately by everyone around them — someone else quietly picks up the slack, deadlines slip, and the team's trust in the hiring process itself takes a hit. We've seen good finance managers spend more time managing around a bad hire than they would have spent just doing the work themselves.
The root cause, almost every time, is the same: the process showed the wrong things. A CV shows what someone claims. An hour-long interview shows how someone performs under interview conditions, which correlates surprisingly weakly with how they perform doing the actual job. Neither step shows you someone matching, batching and coding real invoices, handling a genuinely awkward supplier call, or working at the pace month-end actually demands.
This is exactly the gap a working interview closes. The candidate spends a real day in your team, on your systems, with your actual workload — and you see directly whether they can do the job, rather than inferring it from how they answered a hypothetical question about it. We're confident enough in our own matching that we cover the cost if you're anything less than 100% satisfied after that first day.
The other lever most businesses underuse is being genuinely specific about what "good" looks like before the search even starts. "Experienced Purchase Ledger Clerk" is not a specification — how many invoices a week, what systems, sole-charge or part of a team, studying AAT or not — and a Market Expert who actually knows your local market can shortlist far more accurately against real specifics than against a vague job title.
None of this means hiring has to be slow. It means the time goes in the right places: a tighter brief up front, a working interview instead of (or alongside) a second-round interview, and references that actually get called rather than just collected. A hire that costs a day longer to make and lands correctly is cheaper than one that's a day faster and has to be unwound six weeks later.
