Best HR Software for Startups in 2026: What to Buy at 10, 50 and 150 People
Quick definition: HR software for startups is the set of tools a company uses to pay people legally, keep employee records, hire, track leave and attendance, and later run reviews, training and pay bands. Most startups need payroll with tax filing at the first hire, an HR record at about 10 people, and specialist tools only after 50.
Disclosure: TracefyHR is our product. We include it where it genuinely fits and say where it does not. It is not ranked first. No vendor paid to be included in this list or for its position, and if that ever changes the listing will be clearly marked as sponsored. Prices come from each vendor's own pricing pages and documentation, checked October 2026. Vendors change packaging often, so confirm current terms before you sign.
Short answer: For US-only startups that need payroll and tax filing first, Gusto. For one employee record shared by HR, payroll and IT, Rippling. For early hires in other countries, Deel. For US benefits through a PEO, Justworks. For an HR record once you pass 25 people, BambooHR. For culture-heavy teams heading toward 200, HiBob. For European startups, Personio. For a flat-priced HR system when someone else files your payroll taxes, TracefyHR.
Most lists for this search rank eight platforms as if a 6-person company and a 140-person company had the same problem. They don't. Needs change with headcount, and in the US several laws switch on at 20, 50 and 100 employees. So this guide starts with the stack by stage, prices it at 10, 50 and 150 people, and only then compares platforms.
What HR software does a startup need at each stage?
Buy for the next 12 months of headcount, not the next five years. Here is the usual order, with the trigger that forces each step.
| Headcount | What changes | What to add |
|---|---|---|
| First employee | You withhold and file payroll taxes. In the UK, pension auto-enrolment duties start the day your first worker starts, per The Pensions Regulator. | Payroll that files taxes, or an employer of record abroad |
| About 10 | Contracts, leave requests and onboarding outgrow one founder's inbox | An HR record (HRIS), leave and attendance |
| 20 (US) | COBRA applies to group health plans of employers with 20 or more employees in the prior year, per the Department of Labor | Benefits administration or a PEO |
| 50 (US) | An average of 50 full-time employees, counting equivalents, makes you an applicable large employer under the ACA (IRS). FMLA covers employers with 50 or more employees in 20 or more workweeks (DOL). | Leave tracking that handles FMLA, ACA reporting through payroll or benefits |
| 100 (US) | Private employers with 100 or more employees file the EEO-1 Component 1 report, per the EEOC | HR reporting with demographic fields |
| 150 (EU) | Employers with 150 to 249 workers owe a first gender pay gap report by 7 June 2027 under the EU Pay Transparency Directive, where national law is in place | Pay bands and clean compensation data |
1 to 10 employees: payroll and compliance first
Your first HR purchase is payroll that pays people and files the taxes. Our comparison of payroll software for small businesses covers the options, and the guide to payroll tax filing software explains which tools actually file and which only calculate.
Don't buy a full HR suite for five people. The playbook for hiring your first 10 employees covers the paperwork you need before any software does.
10 to 50 employees: the HR record, hiring, time and leave
Somewhere around 10 people, the founder stops knowing who is off next Thursday. That is the moment for an HRIS: one record per person with contract, documents, leave balance and manager.
Hiring breaks next. With three or more roles open at once, an applicant tracking system built for small teams stops candidates getting lost in email. Leave requests in chat break at about the same time, so compare leave management software before your first busy holiday season.
Hourly, field or site staff need proof of who worked when: see our list of attendance tracking software. If the real problem is building shift rotas, you need a scheduler, covered in the best workforce management software for small businesses. Once several people spend company money, team expense management software beats a shared receipts folder.
50 to 150 employees: engagement, performance, learning and pay
Past 50, managers manage managers and you can no longer read the mood by walking the floor. That is when a survey tool earns its fee; our comparison of employee engagement software separates survey tools from performance suites. Remote and multi-site teams often add a peer recognition tool too, because good work stops being visible outside the room.
If you onboard people monthly or must prove compliance training, a learning management system for small businesses replaces the slide deck. Pay comes last: salary range laws and the EU reporting duty both need written pay bands, which a compensation management tool helps you build and defend.
Hiring abroad, at any stage
If your best candidate lives where you have no company, read our guide to EOR vs PEO vs contractor first. For a full employee without opening an entity, compare the best employer of record services; list prices start at $599 per employee per month at both Deel and Remote. If the person is genuinely independent, contractor management software handles contracts, invoices and cross-border payments.

How we compared startup HR platforms
We read each vendor's pricing page, product documentation and public help centre, checked October 2026. We did not buy paid accounts, so nothing below is a claim about day-to-day use. We asked four questions of each platform:
- What does it handle at the first hire: tax filing, benefits, international employment?
- What does it cost at 10, 50 and 150 people at list price, and is that price published?
- Where does it work: the US, Europe, or many countries?
- What does it not do, so you know what else you will buy?
Which core HR platforms are best for startups in 2026?
These are core platforms, the system that holds the employee record and usually payroll. The order follows the stage at which most startups need each one, not a quality score.
1. Gusto: best for US-only startups that need payroll and tax filing first
Gusto is US payroll with HR tools around it, and its pricing is complete, published and month to month. Simple is $49 a month plus $6 per person for payroll in one state, tax filings included. Plus is $80 plus $12 per person and adds multi-state payroll, time tracking and scheduling. Premium is $180 plus $22 per person, with a named advisor.
The drawback grows with you: 150 people on Plus is $1,880 a month before add-ons. Outside the US, the pricing page covers contractor payments to 120+ countries, not employees, so skip Gusto if your first hires are abroad.
2. Rippling: best when HR, payroll and IT should share one employee record
Rippling runs payroll, benefits, devices and app access off a single employee profile. Its IT management product sets up laptops and app access from a new hire's role and department, and revokes them at termination.
Pricing is the weak spot. The pricing page says plans start at $8 per employee per month plus a monthly base fee, but the fee is not published and the final number is a custom quote. Eligible US VC-backed startups can get six months free. The $8 floor is not what a 50-person company with payroll, benefits and IT will pay.
3. Deel: best when your early hires live in other countries
Skip Deel if everyone is in one US state; Gusto or Justworks will cost less. If your second engineer is in Poland and your third in Brazil, Deel keeps contractors, employer-of-record staff and your own employees in one system, billed month to month.
Its pricing page lists employer of record at $599 per employee per month, contractors at $49 per contractor per month and US PEO at $125 per employee per month. Deel HR Core starts at $5 per employee per month, but the higher tiers with performance, learning and compensation show no price. At $599 a head, EOR gets expensive past a handful of people in one country, which is usually the signal to open your own entity.
4. Justworks: best for US startups that want big-company benefits through a PEO
A PEO becomes the co-employer of your staff, which lets a 15-person company buy health insurance on large-group terms and hand off much of the compliance work. Justworks lists PEO Basic at $79 per employee per month (payroll, compliance, HR consulting, 401(k), 24/7 support) and PEO Plus at $124, which adds medical, dental and vision administration and HSA and FSA accounts.
The catch is cost per head: at 50 people, PEO Basic is $3,950 a month before premiums, nearly six times Gusto Plus. Without health insurance to offer, start with payroll.
5. BambooHR: best HR record once you pass 25 people
BambooHR's pricing is a flat rate up to 25 employees ($250 a month for Core, $425 for Pro, $650 for Elite). Past 25, every employee is billed per head: $10.25 for Core, $17.50 for Pro and $25 for Elite, with automatic volume discounts. It is an HR system first, with payroll, benefits administration and time tracking sold as add-ons whose prices are not published.
At 10 people, $250 is $25 a head for the HR record alone, which is why it fits better past 25. Until December 31, 2026, customers who commit to 12 months on qualifying BambooHR Payroll plans can get payroll subscription fees at $0.
6. HiBob: best for culture-heavy teams heading toward 200
HiBob (the product is called Bob) is built around profiles, org charts and lifecycle workflows that employees use, not only HR. Every plan includes the Core platform, which its pricing page lists as the employee database, documents, time off, lifecycle workflows, integrations, analytics, a mobile app and an AI companion. Talent, payroll and benefits, and compensation planning are add-on modules.
No prices are published. HiBob's FAQ names "Growth" as its segment for companies under 200 employees, but expect a sales process, and for a 12-person team it is more system than you need.
7. Personio: best for European startups
Personio is a Munich-based HR platform aimed at small and mid-sized European employers. A startup with staff in Germany, Spain or the Netherlands gets a vendor that started in the European market instead of adapting a US product to it. Pricing is quote-based and depends on headcount and add-ons; we found no published per-employee price for 2026. A US-only startup has little reason to choose it.
8. TracefyHR: best flat-priced HR system when someone else files your payroll taxes
TracefyHR is our product, so read this one with that in mind. Start with the gaps: it does not file payroll taxes, act as an employer of record or PEO, pay contractors or run benefits. It has no rota builder or shift swapping, no engagement surveys, no recognition programme, no course hosting and no compensation benchmarking. A US startup still needs a tax-filing payroll provider beside it.
What it covers, for 5 to 150 employees: employee records, payroll calculation in 20+ currencies with payslips, leave, attendance with GPS-tagged and offline mobile check-in, named work schedules, hiring with an ATS and careers page, team expenses, and a free iPhone and Android employee app. Pricing is flat: Starter $20 a month for up to 15 employees, Professional $49 for up to 50, Business $99 for up to 150 and Enterprise from $199. A team that outgrows its plan moves up to the next one; there is never a per-employee fee. Annual billing saves 20%; AI is billed separately as pay-as-you-go credits.
What does startup HR software cost at 10, 50 and 150 people?
Monthly list prices, checked October 2026, before add-ons, insurance premiums, implementation fees or annual discounts. The products do different jobs, so compare within a row.
| Product | What the price covers | 10 people | 50 people | 150 people |
|---|---|---|---|---|
| Gusto Simple | US payroll and tax filing, one state | $109 | $349 | $949 |
| Gusto Plus | Multi-state payroll, time tracking | $200 | $680 | $1,880 |
| Justworks PEO Basic | PEO: payroll, compliance, HR support | $790 | $3,950 | $11,850 |
| Justworks PEO Plus | PEO with health benefits administration | $1,240 | $6,200 | $18,600 |
| BambooHR Core | HR record only, no payroll | $250 | $512.50 | $1,537.50 |
| Deel HR Core | HR record only, no payroll | $50 | $250 | $750 |
| Rippling | Starting price per employee | $80 plus base fee | $400 plus base fee | $1,200 plus base fee |
| HiBob, Personio | Core HR | Quote | Quote | Quote |
| TracefyHR | HR record, payroll calculation, attendance; no tax filing | $20 | $49 | $99 |
| Deel or Remote EOR | Per employee abroad, no entity needed | From $599 per hire | From $599 per hire | From $599 per hire |
Per-employee pricing looks cheap at 10 people and grows fast: the gap between Gusto Simple and a PEO is $681 a month at 10 people and $10,901 at 150. A realistic 50-person US stack is often two lines from this table, an HR record plus payroll. Our breakdown of flat vs per-employee HR software pricing works through that math. Remote's EOR figure is a "starting at" price on its pricing page and varies by country.
Key takeaways
- A startup's first HR purchase is payroll that files taxes, or an employer of record if the first hire is abroad.
- In the US, COBRA applies at 20 employees, the ACA large-employer rules and FMLA at 50, and EEO-1 reporting at 100.
- At 50 people, Gusto Plus lists at $680 a month and Justworks PEO Basic at $3,950, because a PEO adds benefits access and outsourced compliance.
- Rippling, HiBob and Personio do not publish full prices, so get written quotes at your expected 12-month headcount.
- TracefyHR charges a flat $20, $49 or $99 a month but does not file payroll taxes, run benefits or act as an employer of record.
Frequently Asked Questions
What HR software should a startup buy first?
Payroll that calculates pay and files taxes, because that is the first legal duty of having employees. If your first hire is in a country where you have no company, use an employer of record.
When does a startup need an HRIS?
Usually at about 10 employees, when contracts, leave requests and documents no longer fit in one person's inbox. Before that, payroll and a shared folder are enough, though UK pension duties start with the first employee.
Is a PEO worth it for a small startup?
It can be if you want to offer competitive US health insurance early, since the PEO buys on large-group terms. If you don't offer benefits yet, a payroll tool costs a fraction of the price.
How much does HR software cost for a startup?
At 10 people, from $20 a month for a flat-priced HRIS to $109 for US payroll, and $790 or more for a PEO. At 150 people, US payroll lists at $949 to $1,880 a month and a PEO at over $11,000.
What is the difference between a PEO and an employer of record?
A PEO co-employs staff in a country where you already have a company. An employer of record legally employs people for you in countries where you have no entity.
TracefyHR fits startups of 5 to 150 people that want the HR record, attendance, leave, hiring and expenses on one flat price, alongside whoever files their payroll taxes. See how it works for startups, compare the flat plans, or start a 30 day trial with no card.
