HR Software for 5 Employees: Is It Worth It?
At 5 employees, most founders manage HR manually. Here's what you actually need, what's free, and when paying for HR software starts to make sense for a tiny team.
At 5 employees, paid HR software is rarely essential - but the free tools available are better than most founders realise, and the compliance requirements are non-negotiable regardless of which tools you use.
What You Legally Need at 5 Employees
Before deciding on software, understand what is legally required. These obligations exist from your first employee and do not disappear because you are a small business:
Contracts: Every employee must have a written statement of employment particulars from day one of employment. This is a legal requirement under the Employment Rights Act 1996.
Right to work: You must check every employee's right to work in the UK before employment starts and keep a copy of the evidence. Failure to do so can result in a civil penalty of up to £20,000 per illegal worker.
Payroll registration: You must register as an employer with HMRC before your first payroll run and submit Real Time Information (RTI) returns on or before each payday.
Auto-enrolment: As soon as you employ anyone aged 22-66 earning over £10,000 per year, you must enrol them in a qualifying workplace pension and contribute at least 3% employer contribution. This applies from your first eligible employee.
Records: Payroll records for at least 3 years. Right to work documents for the duration of employment plus 2 years.
None of this requires paid software. But all of it requires a reliable system.
Free Tools That Work at 5 Employees
Payroll: HMRC Basic PAYE Tools Free, government-provided software that handles payroll calculations, payslips, and RTI submissions for up to 9 employees. It is not elegant, but it works. Download from GOV.UK. Limitations: no automatic pension calculations, no employee self-service.
Pension: Nest The government-backed workplace pension scheme is free to set up for employers. Contributions are managed online, and Nest handles the regulatory compliance side. Most payroll software integrates with Nest, but the manual process is manageable at 5 employees.
Contracts: GOV.UK templates ACAS and GOV.UK offer free employment contract templates. These are legally compliant starting points, though you should review them against your specific arrangements (especially for unusual working patterns, probation periods, or sector-specific requirements).
Holiday tracking: Spreadsheet A simple spreadsheet with each employee's entitlement, taken dates, and remaining balance is adequate at 5 employees. GOV.UK also has a free holiday entitlement calculator you can use to check accrual for part-time and irregular-hours workers.
Document storage: Google Workspace or Microsoft 365 If you already pay for cloud office software, use it. A simple folder structure per employee covering their contract, right to work evidence, and correspondence is sufficient at this scale.
The ROI Calculation for Tiny Teams
Entry-level paid HR software for 5 employees typically costs £25-50 per month. Here is when that cost is justified:
Time savings: If you spend more than 30 minutes per week on HR admin that software would automate, the software pays for itself at a modest £50/hour opportunity cost.
Compliance peace of mind: If you are not confident your records are complete - or you have had a near-miss - the cost of a subscription is trivial compared to an employment tribunal or HMRC investigation.
Growth trajectory: If you expect to be at 10+ employees within 12 months, starting with software now avoids a painful migration later and builds good habits early.
Part-time and variable-hours staff: Holiday accrual for part-time workers is calculated differently and is easy to get wrong manually. Software handles this automatically.
| Scenario | Recommendation |
|---|---|
| 5 permanent full-time staff, no growth plans | Free tools adequate |
| Mix of full-time and part-time workers | Consider paid software for holiday management |
| Growing rapidly (plan to hire 3+ in 12 months) | Start with paid software now |
| Previous compliance issue | Paid software worth the cost |
| Spending 2+ hours/week on HR admin | Software ROI is positive |
What Paid Entry-Level Software Adds
If you decide to pay, what do you get that the free tools do not offer?
- Employee self-service: Staff submit holiday requests through an app; you approve with one click. Eliminates the "did you get my holiday request?" conversation.
- Automated absence tracking: Sickness, lateness, and absence patterns visible in one place.
- Document e-signatures: Send a contract, employee signs digitally. Legally valid under UK law.
- Auto-enrolment integration: Payroll and pension contributions linked and calculated automatically.
- Compliance alerts: Reminders when right to work documents expire, probation periods end, or other deadlines approach.
- Mobile access: Manage HR from your phone, which matters if you are not desk-based.
Providers worth considering at 5 employees: Breathe HR (popular with UK SMEs, from around £18/month), BrightHR, and HRCloud. Most offer free trials.
The Honest Assessment
At exactly 5 employees with a straightforward workforce and no immediate growth plans, you probably do not need to spend money on HR software yet. The free tools cover the legal requirements, and the compliance gap is manageable if you are organised.
The moment to upgrade is when you hire your sixth or seventh employee, when you take on your first part-time or shift worker, or when HR admin starts taking time you do not have. At that point, the cost-benefit calculation shifts clearly in favour of paid software.
What you should not do is use the absence of software as a reason to skip compliance requirements. The legal obligations exist regardless of the tools you use.
This is guidance, not legal advice. For specific questions about your employment arrangements, consult ACAS or an employment solicitor.

Frequently Asked Questions
- Do I need HR software for 5 employees?
- Usually not, but it depends on your situation. At 5 employees, HMRC's free Basic PAYE Tools handles payroll, and a simple spreadsheet can manage holiday. You do need proper contracts, right to work records, and auto-enrolment in place regardless. Paid HR software becomes worthwhile if you are growing, spending significant time on HR admin, or managing complexity like shift patterns or multiple part-time staff.
- What HR software is free for small businesses?
- HMRC's Basic PAYE Tools is free and handles payroll for up to 9 employees. The Pensions Regulator's online tools support auto-enrolment management. Some HR platforms offer free tiers - Factorial and Zoho People have limited free plans. GOV.UK provides free contract templates, right to work checklist, and policy guides.
- What does a 5-person business legally need for HR?
- Legally, you need written contracts for all employees, right to work checks before employment starts, a workplace pension scheme with auto-enrolment, payroll with HMRC registration, and records kept for the required periods (payroll records 3 years, right to work documents while employed plus 2 years). You also need a basic health and safety policy.
- When should a small business start paying for HR software?
- The typical trigger points are: reaching 8-10 employees, hiring your first part-time or hourly worker (holiday accrual gets complicated), experiencing a compliance issue, or spending more than an hour per week on HR admin. At 5 employees, the ROI is marginal for most businesses.
