Payroll software vs payroll bureau: what is the difference?
A plain comparison of self-managed payroll software and a managed payroll bureau — cost, coverage, compliance risk and which is right for different types of UK small business.
Payroll software is a tool the business owner operates — calculations, RTI filing tools and payslip templates. A payroll bureau is a managed service that owns the monthly payroll process on behalf of the business. With software, the business does the work. With a bureau, the bureau does the work. The cost difference is smaller than most business owners expect when the operator's time is factored in.
The core difference
Both payroll software and a managed bureau produce the same outputs: payslips, RTI submissions to HMRC, PAYE calculations, employer NI, pension figures. The difference is who is responsible for making those outputs happen every month.

When payroll software is the right choice
Payroll software works well for businesses where all of the following are true:
—
One or two employees on consistent monthly salaries
—
No starters or leavers in most months
—
The operator understands PAYE and has time to run payroll monthly
—
April rate updates are applied on time each year
—
The operator checks figures before submitting RTI
—
Pension auto-enrolment is actively monitored
If any of these conditions are not reliably met, the compliance risk of self-managed software starts to accumulate — usually quietly, until HMRC writes.
When a managed payroll bureau is the right choice
A bureau makes more sense when:
—
Three or more employees, especially with variable pay or hours
—
Starters and leavers are regular
—
CIS subcontractors are being paid alongside PAYE employees
—
The business owner has limited time for monthly admin
—
Previous payroll has fallen behind or RTI has been missed
—
HMRC has written about late submissions or underpaid PAYE
—
An accountant was handling payroll but is no longer doing so
The real cost comparison
The subscription cost of payroll software is lower than a bureau fee. But payroll software does not include the operator's time.

£540–£2,400 (based on employee count)

Operator-dependent

For businesses with 3–10 employees, the total cost of software plus operator time typically exceeds the bureau fee. For businesses with 1–2 employees where the operator is reliable, software remains viable.

For very simple payrolls with one or two employees on consistent salaries, payroll software can work well if the business owner runs it correctly every month. For businesses with starters, leavers, variable pay, CIS, director payroll or limited time, a managed payroll bureau is the better choice — it removes the monthly obligation entirely.
Payroll software subscription costs £10–£60 per month. A managed bureau costs £45–£200 per month depending on employee count. However, software requires 1–3 hours of operator time per month. When valued at a business owner's hourly rate, the total cost of software often exceeds the bureau fee — before accounting for compliance risk.
Payroll software includes the tools to file RTI — but the employer must initiate the submission. The software does not file automatically on its own. If the business owner runs the payroll but forgets to submit the FPS, RTI is late. A managed bureau files RTI as a non-negotiable step in their monthly process.
Common risks: RTI submitted late or forgotten; April rate changes not applied; new starter put on wrong tax code; pension assessment skipped for a new joiner; director NI calculated monthly instead of annually; software running without the user understanding the figures it is producing.
Yes. A managed bureau needs the year-to-date payroll data for each employee to continue from the correct position. Mid-year transfers are straightforward for a competent bureau. Waiting until April is not necessary.
A bureau owns the monthly process: chasing late payroll data from the client, reviewing figures for anomalies before filing, filing RTI on a fixed calendar regardless of the employer's workload, managing starters and leavers as they happen, and maintaining records and audit trails that protect the employer if HMRC queries arise.
