Somewhere between your first employee, per the first-hire playbook, and your fiftieth, every people task lands on you: contracts, rotas, reviews, disputes, leavers. Hiring an HR manager at eight staff makes no financial sense; running on improvisation makes no legal sense. The answer is a minimum viable system - five parts, a few hours a month, most of it automated or outsourced.
- Under twenty staff, you are the HR department - the goal is a system that takes hours a month, not a person who costs a salary.
- Five parts cover it: clean files, a hiring system, an onboarding-and-feedback rhythm, a compliance calendar, and outsourced payroll.
- Automate the mechanical (payroll, scheduling, hiring funnel), template the repeatable (contracts, reviews), and keep only judgement for yourself.
- The first HR hire pays around 30 to 50 staff - before that, buy systems and fractional expertise, not headcount.
Part one: the files that save you later
One folder per person - contract and every variation, registration paperwork, absence and leave log, dated feedback notes, training records - maintained as events happen, stored per data rules. This is an hour to set up and minutes per month to keep, and it is the difference between evidence and anecdote at every future flashpoint: the probation exit per letting someone go, the inspection, the reference request, the dispute. If you build only one HR habit, build this one.
Parts two and three: the people rhythms
Hiring becomes a system rather than an emergency with the standing kit from same-week hiring: defined roles, an honest ad template, automated screening and scheduling - the whole recruiting function running as software plus your judgement, per recruitment automation. Onboarding-and-feedback is the retention rhythm: the written first week from onboarding, a probation review that actually happens per the probation guide, one structured conversation per person per quarter (twenty minutes: going well, hard right now, what next), and exit interviews closing the loop. None of this needs an HR title - it needs calendar slots that survive busy weeks.
Parts four and five: compliance and payroll
- The compliance calendar: one page of recurring dates - contract deadlines, probation ends, registration renewals, safety checks, leave-year events - reviewed monthly. Ambush compliance is the expensive kind.
- Payroll, outsourced on day one: an accountant or bureau runs wages, contributions and filings for tens of euro a month - the single best HR outsourcing trade at any size.
- Scheduling software where shifts exist, per shift planning - rota fairness is retention infrastructure, and apps enforce it cheaper than memory.
- Expertise on call, not on payroll: an employment lawyer or fractional HR consultant for dismissals, disputes and restructures - hours of the real thing beat a full-time approximation.
What only you can do
The system handles the mechanical so the owner's hours go where judgement lives: choosing who to hire on the evidence, having the honest conversations early per acting on mismatches, deciding pay against the market, promoting per internal mobility, and setting the tone the files and rhythms merely record. When those judgement hours themselves overflow - typically past thirty-plus staff, multiple sites or heavy regulation - that is the honest signal for the first dedicated people hire, per when to hire: brought in to run a working system, not to excavate years of improvisation.
The takeaway
Under twenty staff, HR is a system, not a person: files kept as you go, hiring and onboarding on rails, a compliance calendar, payroll outsourced, judgement reserved for yourself and experts on call for the sharp edges. A few hours a month, mostly automated - and the first dispute, inspection or growth spurt finds you documented instead of improvising.

What HR do I legally need with a handful of staff?
The core is the same almost everywhere: written contracts issued on time, registration before day one where your country requires it, payroll run correctly with contributions, working-time and leave records kept, basic safety obligations met, and employee data handled lawfully. Country specifics live in our country guides - but note that most obligations bind from employee one, not from some comfortable threshold. An accountant-run payroll plus a one-page compliance calendar covers the recurring load in a few hours a month.
What breaks first when there is no HR system?
Documentation, silently: the contract variation agreed verbally, the warning never written down, the leave balance in someone's head. Everything works until the first dispute, inspection or bad exit - and then the absence of paper decides against you. The fix costs almost nothing prospectively: one folder per employee (contract, variations, absence log, feedback notes), filled as things happen. Retroactive reconstruction, the alternative, is expensive and unconvincing.
When does hiring an actual HR person make sense?
The common crossover is 30 to 50 staff, or earlier with heavy shift complexity, multiple sites or regulated workforces. Before that, the same money buys more as systems plus fractional help: outsourced payroll, hiring automation, scheduling software, and an employment lawyer or fractional HR consultant on call for the genuinely hard moments (dismissals, disputes, restructures). The failure mode is hiring an office manager, calling them HR, and giving them neither training nor authority - paper coverage, real exposure.
