HR software typically pays for itself between 5 and 10 employees, when holiday clashes, missing documents and onboarding gaps start costing more than the £20 to £40 a month the software does. With Employment Rights Act 2025 changes in force from April 2026 and tribunal claims rising, timestamped records of policies, training and warnings are the quiet business case.
TL;DR · LAST REVIEWED 25 JULY 2026
- The payback point arrives around 5 to 10 employees; below that a spreadsheet genuinely still works
- Banded pricing holds steady as a band fills, favouring stable teams; per employee pricing tracks headcount, favouring seasonal ones
- Employment Rights Act 2025 changes took effect April 2026, expanding day one rights and raising the value of records
- The average unfair dismissal award runs around £13,749 before legal fees; cases turn on documentation
- Bundled legal advice lines suit employers with no HR support; firms already retaining advisers pay twice
KEY FACTS
- Entry pricing: free tiers exist for micro teams; banded plans run roughly £22 to £24 a month for up to 10 employees
- Per employee models start around £7 per user monthly and scale continuously
- Employment Rights Act 2025 commencement: April 2026, with expanded day one rights
- Average unfair dismissal award: around £13,749 before legal fees
- Many small business platforms exclude native payroll; pay runs need a bureau or integrated alternative
- The right sizing question is headcount in 24 months, not today
Compliance is the quiet business case
From April 2026 the Employment Rights Act 2025 brought expanded day one rights, and tribunal activity is rising. Cases are commonly won and lost on records: software that timestamps policies issued, training completed and warnings given is inexpensive insurance against a five figure award.
That documentation function, more than holiday booking, is what justifies the subscription for most small employers, with the average unfair dismissal award around £13,749 before legal costs.
Pricing models, matched to teams
Banded pricing holds its price as a band fills, which favours stable teams growing within a band. Per employee pricing tracks headcount exactly, which favours very small or seasonal teams. Running both models against a realistic 24 month headcount settles the choice.
The advice versus software split matters equally: bundled 24/7 employment law advice lines suit firms with no HR expertise at all, while a firm already paying an HR consultant is paying twice for advice and usually does better with pure software pricing. Many small business platforms carry no native payroll, which is fine where a bookkeeper or bureau already runs pay.
Choosing by trajectory
The right question is headcount in 24 months. Entry platforms price for teams up to roughly 25 to 30; mid tier banded products run to 200; per employee platforms scale continuously; and the heavyweight suites are designed for organisations approaching 50 and beyond.
Starting a rung too high buys complexity nobody uses; a rung too low forces a migration mid growth, which is the more expensive mistake. Free trials against real workflows beat feature checklists.

Frequently asked questions
What does HR software cost for a UK small business?
From free tiers for micro teams to roughly £22 to £40 a month for teams of ten on banded plans, and around £7 upwards per user monthly on per employee models.
At what size does a business need HR software?
Commonly between 5 and 10 employees, when leave tracking, document storage and onboarding stop fitting comfortably in a spreadsheet.
Does HR software include payroll?
Often not at the small business tier: many platforms manage people and absence but not pay runs. Integrated payroll exists at some providers; others pair with a bureau.
Why does documentation matter so much from 2026?
The Employment Rights Act 2025 took effect in April 2026 with expanded day one rights, and tribunal activity is rising. Timestamped records of policies, training and warnings are frequently decisive evidence.
Is bundled legal advice worth paying for?
For employers with no HR expertise, yes: the advice line substitutes for retained support. Firms already paying advisers duplicate cost and usually prefer software only pricing.
Banded or per employee pricing?
Banded for stable teams (the price holds as the band fills), per employee for very small or seasonal ones. Cross the maths at a realistic 24 month headcount.
