How to choose an HR system

Write down everything that happens around your people in one month. How many people start, how many contracts and amendments, how many times attendance gets corrected before payday, how many deadlines someone is keeping in their head. That list is the spec. Without it you'll compare features you may never use — and miss the one you're doing this for.

54.4% of HR staff spend three hours or more a day on administration. The area they most often name for digitization is drafting employment contracts and documents — 58.7%.

Systems don't differ by feature count. They differ on seven things you only find out in daily use: whether they cover your work, whether they connect to payroll, whether you can trial them, how fast they go live, whether you can switch them on in stages, what an employee sees, and how well they fit the law you work under.

Local HR systems. Built around local legislation, with integrations to the accounting software Czech companies actually run, and support in the local language. Narrower than the global platforms, but they fit how the work really gets done.

Global HR platforms. Broad functionality, strong analytics, usually more expensive. Local legislation and connections to Czech payroll systems get passing attention, or none.

Payroll and accounting software with an HR module. You already have it, so it looks like the cheapest route. It will usually cover records, but not onboarding, reviews, training or employee self-⁠service.

Spreadsheets and shared drives. These hold up longer than anyone expects — until an audit lands, the person who maintained the files leaves, or headcount outgrows what anyone can keep track of by hand.

Take the hours that go into HR routine every week — the ones you wrote down at the start. Multiply them by what an hour of that work really costs you, salary plus employer contributions rather than the gross hourly rate. In the Czech Republic that works out to roughly CZK 370 (the median gross wage for an HR role plus employer contributions of 33.8%, at ~170 hours a month); use your own number if you're somewhere else.

Put the result next to the monthly price of the system. Don't use the savings a vendor promises you. Use the hours you already know about.

These questions go after what a website and a sales deck won't tell you: what the system does today and what's still a promise, who maintains the connection to your payroll, how much work stays on your side, and how you get your data back out when you're done.

If the answer to questions 2, 4 and 8 is “I'll show you on the demo”, that's an answer in itself.

Choosing by the length of the feature list. A feature you never switch on is worth nothing. What counts is the overlap with your list, not the total.

Skipping the trial. The vendor runs the demo. You run the trial — and that's where you find out whether you can use the thing without being walked through every step.

Deciding without the people who will work in it. A system picked by management alone usually ends with the old spreadsheet still running next to it.

Switching everything on at once. Eight modules in one day means eight sources of resistance at once.

Underestimating the migration. Data in five spreadsheets across three places doesn't move itself. Ask who does it and what format each thing has to arrive in.

Employee data falls under GDPR, so ask where it physically sits and who has access to it. If a system uses AI to recruit or evaluate people, the EU AI Act treats that as a high-⁠risk use (Annex III, point 4), with December 2, 2027 as the deadline for full compliance. That isn't a reason to avoid AI — it's a reason to ask the vendor how they've handled it.

Before you sign, run through the ten items below. Each one maps to a chapter of this guide. If you hesitate on any of them, that's exactly where these decisions tend to break — and asking now costs less than finding out after signing, when the contract is harder to move.

The five questions that come up most often while you're choosing — how long it takes, what it costs, whether it pays off without a full-⁠time HR person, whether to go local or international, and whether you can try anything for free.
