What Do Payroll Services Include for Small Businesses?
A standard payroll service calculates and pays your employees, deducts the right tax and National Insurance, reports everything to HMRC on time and keeps the records to prove it. Most providers also handle pension auto-enrolment, payslips and statutory payments such as sick pay and maternity pay as part of the core service.
What varies a lot more than people expect is where the line sits between what's included and what's billed separately. This guide goes through everything a payroll service typically covers, what's often an add on rather than a core feature, and what payroll looks like specifically for a small business or a single director limited company in Bristol.

The Core Services Included in a Standard Payroll Service
Most UK payroll services, whether that's an accountant, a dedicated payroll bureau, or a piece of software, cover the same core ground.
| Core service | What it covers |
|---|---|
| Payroll calculations | Gross to net pay, Income Tax, employee and employer National Insurance |
| RTI submissions | Full Payment Submission sent to HMRC on or before each payday |
| Payslips | Digital or printed payslips issued to every employee each pay run |
| PAYE setup and management | Registering a new PAYE scheme and keeping it running correctly |
| Pension auto-enrolment | Assessing eligibility, enrolling qualifying staff, processing contributions |
| Starter and leaver processing | New starter checklists, P45s for leavers, updating HMRC records |
| Statutory payments | Sick pay, maternity, paternity, adoption and shared parental pay |
| Year end reporting | P60s for employees, final submission for the tax year |
Below, each of these is worth understanding in a bit more detail, since the depth behind each one varies between providers.
Payroll Calculations and RTI Submissions
Every pay run, a payroll service works out exactly what each employee is owed, and what needs to be deducted before it reaches them. This includes Income Tax based on the employee's tax code, employee National Insurance, and the employer's own National Insurance contribution on top.
This information has to reach HMRC through Real Time Information, specifically a Full Payment Submission sent on or before payday. Missing this deadline carries a monthly penalty, so a reliable service should never leave this to the last minute.
Payslips and Employee Records
Every employee is legally entitled to a payslip showing gross pay, deductions and net pay for each pay period. Most payroll services now deliver this digitally through a portal or app, though a printed option should still be available if needed.
Alongside payslips, a proper payroll service keeps accurate records of hours worked, pay rates, tax codes and any changes throughout the year, records you're required to keep for at least three years after the tax year they relate to.
Pension Auto-Enrolment
Employers must assess every worker for auto-enrolment, enrol those who qualify, and manage ongoing contributions, and this applies even to businesses with just one or two staff. A proper payroll service handles this as standard, including the three yearly re-enrolment exercise that catches a lot of small businesses out if nobody's tracking it.
What's less commonly included, and worth asking about directly, is choosing or setting up the pension scheme itself. Some providers handle this end to end, others expect you to already have a scheme in place and simply process the contributions.
Starter and Leaver Processing
When someone joins or leaves, there's a specific set of administrative steps a payroll service should handle. For new starters, that means collecting a starter checklist, setting up the correct tax code, and registering them on your PAYE scheme. For leavers, that means processing a final payment correctly and issuing a P45.
Getting this wrong is one of the more common sources of tax code errors further down the line, so it's worth confirming this is genuinely built into your provider's standard process rather than something you're expected to chase up yourself.
Statutory Payments
Statutory payments cover sick pay, maternity, paternity, adoption and shared parental pay, and a payroll service should calculate these correctly based on current rules. The rules changed for statutory sick pay from 6 April 2026, it's now payable from the first day of sickness rather than after waiting days, the lower earnings limit has been removed, and payment is the lower of 80 percent of average weekly earnings or the flat weekly rate. A payroll service still working to the old rules will get this wrong.
Year End Reporting
At the end of each tax year, a payroll service issues P60s to every employee showing their total pay and deductions for the year, and submits final reporting to HMRC. This is generally included as standard, though some providers charge a separate year end fee, so it's worth confirming this upfront rather than assuming it's automatically covered.
What's Often Billed as an Extra, Not Included as Standard
A cheaper headline price doesn't always mean a cheaper total cost. A few services commonly sit outside a standard payroll package, even with reputable providers.
P11D benefits in kind reporting, for employees receiving benefits like a company car or private healthcare, is often billed separately from standard payroll processing.
Setting up a new pension scheme from scratch, rather than just processing contributions into an existing one, is sometimes an additional project fee.
Court order and attachment of earnings deductions, which require specific calculation, aren't always included as standard.
CIS deductions, relevant for construction industry subcontractors, need a different process to standard PAYE and aren't automatically covered by every payroll service.
Ad hoc advice, such as a one off question about a complex situation, sometimes falls outside a fixed payroll fee and gets billed by the hour.
If you're also deciding between keeping payroll in-house with specialist advice and handing the ongoing work to an external provider, our guide to payroll consulting vs outsourced payroll explains how the two approaches differ.
What This Looks Like for a Single Director Limited Company
Payroll for a business with one employee, the director, looks different to payroll for a team, and a few things matter here that a general small business payroll guide doesn't usually cover.
Director National Insurance is calculated on an annual basis, not the standard employee method, so payroll software needs to be set correctly for this.
Setting the right salary level matters for more than tax. Too low, and it may not count as a qualifying year for the State Pension. Getting this right is a planning decision, not just a payroll calculation.
Employment Allowance usually isn't available where the director is the sole employee paid above the secondary threshold.
A month with no salary payment may still need reporting to HMRC, otherwise a payment that isn't due can end up being chased.
We've covered the fuller detail on this, along with common payroll mistakes small businesses make, in our guide to common payroll problems small businesses face.

Final Words
A proper payroll service covers far more than simply paying staff on time, calculations, HMRC reporting, pensions, statutory payments and year end filing all need to happen correctly and on schedule. Knowing what's genuinely included, and what's commonly an extra, makes it much easier to compare providers fairly rather than just comparing headline prices.
