Frequently asked questions
When should a small business start using HR software?
Most businesses benefit from HR software once they reach 5-10 employees. At this point, managing leave, contracts, and compliance in spreadsheets becomes risky and time-consuming. The cost of HR software is typically less than one hour of an accountant's time per month.
Do I need HR software if I use an accountant for payroll?
Yes. Payroll and HR serve different functions. HR software manages leave requests, employee records, onboarding, and compliance documentation — none of which your payroll provider typically handles. Many HR platforms integrate with payroll tools.
What is the cheapest HR software for a small UK business?
Grove HR starts at £2.40 per employee per month, making it one of the most affordable UK HR platforms. Breathe HR offers flat-rate pricing from £13 per month for up to 10 employees, which can be cheaper for very small teams.
Can small business HR software handle statutory requirements?
The best UK HR software handles statutory annual leave calculations, SSP tracking, pension auto-enrolment reminders, and right-to-work checks. Look for platforms that include these as standard rather than paid add-ons.
