Best Payroll Software for UK Small Businesses
Payroll is one of those jobs that has to be right every time. We compare practical UK payroll software for sole directors, first-time employers and growing small teams, with a focus on HMRC reporting, pensions, ease of use and how much admin each option actually saves.
Which payroll software should a small business shortlist?
There is no point paying for enterprise-level HR tools if you employ three people. Equally, the cheapest package can become expensive in staff time if payroll is awkward every month.
Xero Payroll
Payroll sits inside Xero accounting, so wage costs and payroll journals flow into the same system you already use.
- RTI submissions to HMRC
- Payroll included for different employee numbers by plan
- Employee leave and pension support
- Useful if bookkeeping is already in Xero
QuickBooks Payroll
Designed to keep payroll close to the books, with Core aimed at directors and smaller teams.
- HMRC-recognised
- Automatic tax-code updates
- RTI submissions
- Pension auto-enrolment support
Sage Payroll
A long-established UK payroll option with clear tiers as your workforce and HR requirements grow.

Do you actually need payroll software?
If you employ staff and run PAYE yourself, you need payroll software that can report PAYE information online to HMRC unless you are exempt. The software needs to record employee details, calculate pay and deductions, report payroll information to HMRC and work out what you owe.
That is the compliance side. For a small employer, the practical reason to use decent payroll software is simpler: you do not want payday turning into half a day of spreadsheets, tax-code checks, pension calculations and correcting avoidable mistakes.
First employee? Start with the boring questions
Before comparing dashboards, check that the software can handle your pay frequency, RTI submissions, statutory pay, pensions, payslips and the number of employees you expect to have in 12 to 24 months. Those basics matter more than flashy extras.
What should a small business look for?
1. HMRC reporting and RTI
Your payroll software should report employee pay and deductions to HMRC on or before payday. For a busy owner, this is one of the biggest reasons to avoid manual workarounds. The right software should make the Full Payment Submission part of the normal pay-run process.
2. Pension auto-enrolment
Your workplace pension duties begin when your first member of staff starts work. Good payroll software should help assess workers, calculate contributions, retain the required information and exchange the right data with your pension scheme.
3. How many people you pay
A director-only company has very different needs from a 20-person café, building firm or agency. Some providers include a set number of employees, while others charge per person. Look at the cost at your current headcount and at the headcount you realistically expect next year.
4. Whether payroll sits inside your accounting system
If you already use accounting software, keeping payroll inside the same ecosystem can save duplication. Xero and QuickBooks are especially compelling when the bookkeeping is already there because payroll journals and wage costs can flow into the accounts automatically.
5. Employee self-service
If employees constantly ask you for payslips, holiday balances or copies of payroll information, a self-service portal or app can save a surprising amount of time. This becomes more useful as your team grows.
6. Support when payroll goes wrong
Payroll problems tend to arrive when you are trying to get everyone paid. Check whether support is included, what channels are available and whether you are comfortable relying on online help alone.

Our view on the main payroll providers
Xero Payroll: best if you already use Xero
Xero’s biggest advantage is not that it is a standalone payroll specialist. It is that payroll sits inside the same accounting platform many small businesses already use for invoices, bills, bank reconciliation and VAT.
From September 2026, Xero’s UK plan pricing changes. Ignite is £18 per month, Grow £39, Comprehensive £55 and Ultimate £70, excluding VAT. Payroll availability varies by plan: Ignite charges £1.50 per person, Grow includes payroll for one person, Comprehensive includes five and Ultimate includes ten.
That means the value calculation is simple. If you already pay for Xero, adding or using its payroll can be far easier than running a separate system. If you only need payroll, buying a broader accounting package may be unnecessary.
QuickBooks Payroll: best for QuickBooks users and first-time employers
QuickBooks offers Core and more advanced payroll options alongside its accounting platform. Core is positioned specifically at director-only businesses and smaller employers that want straightforward payroll without a large HR system.
Current functionality includes automatic calculations, automatic tax-code updates, statutory-pay calculations, RTI submissions, payslip distribution and pension auto-enrolment support.
Sage Payroll: best for businesses that expect payroll and HR needs to grow
Sage currently offers Essentials, Standard and Premium payroll tiers. All include five employees, with additional employees charged separately. Current standard pricing after introductory offers starts at £12 per month for Essentials, £23 for Standard and £34 for Premium, excluding VAT.
The current cloud plans cover HMRC-recognised payroll, pension auto-enrolment, reporting and payslips, while higher tiers add more HR, leave, timesheet and scheduling functionality.
BrightPay: best when payroll itself is the priority
BrightPay is a payroll-first product rather than an accounting suite with payroll bolted on. That can be an advantage if you already have bookkeeping software you like and simply need a dedicated way to handle payroll, pensions and employee information.
It is particularly popular with employers and payroll bureaus that want detailed control without moving all of their accounting into a new ecosystem.
FreeAgent Payroll: best for very small teams already using FreeAgent
FreeAgent is built around freelancers, contractors and small businesses, so its payroll functionality is naturally aimed at smaller employers rather than large HR departments.
Its main attraction is integration with the rest of FreeAgent. If your bookkeeping, expenses, invoices and tax records are already there, keeping payroll in the same system reduces duplicate work.
What happened to Gusto?
The old version of this page recommended Gusto as though it were a mainstream UK PAYE payroll product. We have removed it from the shortlist. Gusto is primarily a US payroll platform, and we do not think it belongs beside established UK PAYE software unless it clearly supports the specific HMRC and workplace-pension requirements a UK employer needs.
What about HMRC Basic PAYE Tools?
HMRC provides Basic PAYE Tools free of charge for businesses with fewer than 10 employees. It can be useful for very small employers with straightforward payroll, but it is intentionally basic. You should check whether it covers the pension, payslip, reporting and workflow features you want before choosing it purely because it is free.
Which payroll software is best for your type of business?
Director-only limited company
Keep it simple. QuickBooks Core, Xero if you already use it, FreeAgent or HMRC Basic PAYE Tools may be enough depending on your accounting setup.
1 to 5 employees
Ease of use matters more than advanced HR. Xero, QuickBooks, Sage and BrightPay are all sensible comparison points.
Growing team
Look more closely at employee self-service, leave management, multiple pay schedules, pension workflows and HR features. Sage and the more advanced QuickBooks tiers become more relevant.
Accountant runs payroll
Ask what system your accountant already uses before buying anything. Paying for software that duplicates their payroll service rarely makes sense.
Payroll software FAQs
Do I legally need payroll software?
If you run PAYE yourself, you generally need payroll software capable of reporting PAYE information online to HMRC unless you are exempt. The software is used to calculate pay and deductions and submit payroll information.
What is RTI?
Real Time Information is the system used to report PAYE information to HMRC. Employers normally submit employee pay and deduction information on or before each payday.
Can I run payroll myself?
Yes. Many small employers run payroll themselves using HMRC-recognised software. The alternative is to use an accountant, bookkeeper or payroll bureau. The right choice depends on how comfortable you are with payroll and whether your time is better spent elsewhere.
What is the best payroll software for one employee?
If you already use Xero, QuickBooks or FreeAgent, keeping payroll in the same package is usually the first option to check. If you need only basic PAYE for fewer than 10 employees, HMRC Basic PAYE Tools may also be worth considering.
Does payroll software handle workplace pensions?
Many payroll products support automatic-enrolment tasks, but the level of support varies. Check whether the software assesses workers, calculates contributions and exchanges the right information with your pension provider.
Bottom line
The best payroll software for a small business is usually the one that removes work rather than creates another system to manage. If you already use Xero or QuickBooks, their payroll products are the obvious first comparison. Sage is a strong choice if you want payroll and HR features that can grow with the business. BrightPay makes sense when dedicated payroll functionality matters most. FreeAgent is particularly useful for micro-businesses already inside its accounting ecosystem.
Do not choose purely on a promotional monthly price. Look at the number of employees included, pension support, RTI submissions, support and what happens to the price as your team grows.
