Choosing Payroll Software for a UK Small Business: What to Check
A practical guide to comparing UK payroll software for small businesses, covering HMRC recognition, costs, pensions, and the features that matter most.
Choosing payroll software is one of those decisions that looks simple until you start comparing options. Every product claims to be easy, HMRC-compliant, and affordable. The differences show up in the details, and those details decide how much time payroll takes each month.
We compare the factors that matter most for UK small businesses, so you can evaluate products on your own terms rather than a vendor’s.
Is the software recognised by HMRC?
This is the first filter. Under Real Time Information, employers must report pay, tax, and National Insurance to HMRC on or before each payday. Only software recognised by HMRC can file those reports.
Most established products qualify, but check the current HMRC-recognised payroll software list before committing. Free and low-cost tiers sometimes lack full filing capability, so confirm the specific plan you are buying, not just the product name.
What will it actually cost?
Pricing models vary widely. Some products charge per employee per month, others charge a flat monthly fee with an employee cap, and some offer free tiers for very small teams.
Look beyond the headline price. Check whether filing to HMRC, automatic pension submissions, year-end forms, and support are included or charged as add-ons. A cheap base plan that charges separately for each filing can cost more than a pricier all-in-one option.
How does it handle workplace pensions?
Automatic enrolment is where many small businesses stumble. Good software assesses employees each pay run, generates the letters you must send, and submits pension data to your provider electronically.
Manual pension assessment is a common hidden cost of cheap software. If you would have to work out contributions on a spreadsheet, factor in that time.
Can it handle pay variations and new starters?
Monthly payroll rarely runs identically each time. You will have starters, leavers, statutory pay, bonuses, and mid-pay-period changes.
Test how the software handles statutory maternity, paternity, and sick pay, and how easily you can correct a mistake after filing. The best products let you resubmit an earlier pay run without redoing everything.
Does it connect to your accounting?
If you already use accounting software, payroll that posts journals automatically saves real time. Check whether an integration exists for your specific accounting product, and whether it works on your payroll plan. Some integrations are reserved for higher tiers.
What support do you get?
When payroll goes wrong, you need answers quickly. Compare support hours, channels, and whether UK-based phone support is included or an extra cost. Free plans often come with community forums only, which is fine until it is not.
Our suggested next step
Draw up a shortlist of two or three products and run the same month of real payroll data through each trial. The one that takes you the least time, with the fewest manual workarounds, is usually the right choice.
