The Sign You've Already Waited Too Long
Most small companies don't hire an HR person until something goes wrong. A manager mishandles a termination, a benefits renewal gets missed, or an employee complaint lands in an owner's inbox with no clear process for handling it. These aren't reasons to hire HR. They're evidence that the hire should have happened six months ago. If your leadership team is regularly making decisions that touch compensation, compliance, or employee relations without any dedicated support, that's the signal.
The Headcount Conversation Is a Starting Point, Not the Answer
You'll hear a lot of rules about headcount thresholds. Fifty employees. One hundred employees. The honest answer is that it depends on the complexity of your workforce, not just the size. A 40-person manufacturing company with shift workers, variable pay, and high turnover needs HR infrastructure earlier than a 60-person professional services firm where most people have been there for years. Think about the volume of employee questions, the pace of hiring, and how much time managers are spending on people issues. That tells you more than a headcount number.
What the Role Actually Needs to Cover
For a first HR hire at a small company, generalist experience matters more than depth in any one area. You need someone who can run payroll coordination, manage open enrollment, handle an employee relations issue with good judgment, support managers on performance conversations, and keep the company out of compliance trouble. That's a wide range. The candidate doesn't need to be an expert in all of it, but they need to be competent across it and know when to bring in outside counsel or a benefits broker for the harder questions.
Where Companies Get the Hire Wrong
Two common mistakes show up here. The first is hiring someone too junior because the budget is tight, then getting frustrated when they can't operate independently. A first HR hire at a small company needs to function without much oversight. The second mistake is bringing in someone with only large-company experience who isn't comfortable building things from scratch. Ask candidates directly about the smallest organization they've supported and what infrastructure existed when they started. The answers matter.
Getting the Hire Right the First Time
A first HR hire tends to shape the people function for years. Taking time to define what the role actually needs to own, what success looks like in the first year, and what kind of leader this person will be supporting goes a long way toward finding the right fit rather than just filling the seat.
