A company can run comfortably with one director on payroll for months, then hire three employees and suddenly find that the monthly pay run has become a recurring administrative deadline.
New starters need to be recorded correctly. Tax codes can change. Bonuses, overtime, statutory payments, pension deductions and employee departures all affect calculations. Employers also have to submit payroll information to HMRC through Real Time Information (RTI), normally sending a Full Payment Submission on or before payday.
For smaller employers without an internal payroll specialist, that makes the decision less about whether payroll software can calculate wages and more about who is responsible for keeping the whole process organised.
There are numerous providers offering payroll services in London, from accountancy practises that manage payroll alongside bookkeeping and tax to specialist payroll bureaux and technology-led platforms.
The right model depends on employee numbers, pay frequency, complexity and how much administration the employer wants to retain.
When Payroll Becomes Difficult to Manage In-House
Payroll often remains manageable while everyone receives a fixed monthly salary and very little changes.
The workload becomes less predictable once a business starts dealing with hourly workers, variable pay, bonuses, statutory leave, starters, leavers or pension deductions. Even a company with relatively few employees can therefore have a more complicated payroll than a larger business whose staff are all paid identical monthly salaries.
There is also a reporting element that cannot simply be dealt with at year-end.
Under RTI, employers generally report employee pay and deductions through a Full Payment Submission (FPS) on or before the employee’s payday. Employers must also maintain payroll records showing what employees were paid, deductions, reports submitted to HMRC and relevant supporting information. HMRC says specified PAYE records normally need to be retained for three years from the end of the tax year to which they relate.
Year-end responsibilities continue as well. Employees who remain employed on 5 April must normally receive a P60 by 31 May.
For a small employer, outsourced payroll can therefore be less about replacing software and more about transferring routine processing and reporting work to people who deal with it every pay period.
What Should an Outsourced Payroll Provider Actually Handle?
The scope varies considerably between providers.
At its simplest, a payroll service may calculate gross-to-net pay, produce payslips and submit payroll information to HMRC. A more comprehensive service might also manage starters and leavers, statutory payments, pension information, payroll reports and year-end documents.
Before comparing payroll companies in London, employers should establish exactly which tasks they expect to outsource.
A useful core specification might include:
- calculating salary, wages and authorised adjustments;
- PAYE and National Insurance calculations;
- preparing and distributing payslips;
- FPS and relevant EPS submissions;
- processing starters, leavers and salary changes;
- producing P45s and P60s where applicable;
- handling pension deductions where included in the service;
- processing statutory payments where relevant; and
- providing payroll reports for accounting and management purposes.
There is an important distinction between managed payroll and payroll software.
Software gives the employer a system through which to process payroll. A managed payroll service involves another organisation performing some or most of the payroll work. Some providers now sit between the two models, combining cloud software with payroll professionals who review or process the data.
Small employers should therefore ask not merely, “Does it include payroll?” but, “Which parts of the payroll process will we still have to complete ourselves?”
How We Approached This Comparison
The providers below have been selected to show several different approaches available to small employers: accountant-led payroll, specialist payroll bureaux, managed payroll services and technology-led platforms.
The comparison is based on services described publicly by the providers themselves, with particular attention to PAYE processing, RTI, payslips, employee changes, wider accounting support and suitability for smaller organisations.
It is not a ranking. Pricing, service levels and suitability can change, and employers should verify the current scope before appointing a provider.

Accounting People
Best suited to: Small businesses, startups and limited companies looking for payroll alongside broader accounting services.
Accounting People describes its payroll offering as being designed for small businesses, startups, contractors and limited companies in London and elsewhere in the UK. Its publicly listed payroll work includes PAYE, payslips, HMRC submissions, pension records and monthly payroll administration.
This accountant-led model may make sense where payroll information also needs to feed into bookkeeping, statutory accounts or other ongoing accounting work.
That distinction matters for smaller companies. Some employers want payroll treated as a standalone HR function, while others prefer the same accountancy provider to have visibility over salary costs and related financial records.
Clarkwell & Co.
Best suited to: London SMEs wanting recurring payroll administration connected with wider accounting and compliance work.
Clarkwell & Co. provides payroll support covering PAYE and National Insurance administration, payroll calculations, payslips, RTI submissions and employee record changes. Its payroll information also refers to starters, leavers, salary changes, statutory payments and payroll documents including P45s and P60s.
That makes Clarkwell & Co.’s payroll services relevant to smaller employers that would rather place payroll alongside their broader accountancy requirements instead of running it as a separate internal function.
The firm’s own service material is aimed particularly at London startups, limited companies and growing SMEs, which gives the offering a relatively specific small-employer context rather than positioning payroll purely as enterprise workforce software.
Direct Payroll Services
Best suited to: Employers looking specifically for an outsourced payroll bureau rather than a wider accounting package.
Direct Payroll Services operates as a payroll specialist and publicly describes services for businesses of different sizes, including small-business payroll and payroll bureau work. It also refers to CIS payroll, making the provider potentially relevant to employers with construction-related payroll requirements.
A specialist bureau model can be useful where a company already has an accountant or finance arrangement it intends to keep.
In that situation, the main comparison point is integration. Employers should establish how reports will be passed to their accountant or bookkeeping system and who is responsible for reconciling payroll liabilities after each pay run.
Moorepay
Best suited to: Growing employers wanting managed payroll combined with payroll technology and potentially wider HR functionality.
Moorepay offers fully managed payroll in addition to software and bureau services. Its managed offering includes payroll processing, payslip distribution, reporting and HMRC-related administration. Employers enter information such as starters, leavers, salary changes and bonuses through its cloud platform before payroll data is processed and checked.
The system also provides employee access to payroll documents and can sit alongside HR functionality.
For a very small employer, the question is whether this broader infrastructure is necessary. For a business expecting headcount or HR administration to become more complex, the ability to keep employee and payroll processes within related systems may carry more weight.
Osome
Best suited to: Digital-first startups and small companies that want payroll within an online accounting service.
Osome combines online accounting with bookkeeping, tax and payroll services. Its current UK packages include varying levels of payroll support, such as PAYE registration, director payroll, and employee payroll, depending on the package selected. It also lists a London address and services specifically for London businesses.
The model is particularly different from a traditional payroll bureau because payroll sits inside a wider digital accounting environment.
That may appeal to founders who already prefer app-based communication and integrated bookkeeping. Employers with more complex workforce arrangements should still establish exactly what payroll events, pension administration, and irregular adjustments are included before relying on package descriptions alone.
PayEscape
Best suited to: Small and growing employers wanting payroll combined with HR and time-and-attendance systems.
PayEscape provides both outsourced and fully managed payroll, alongside software-only options. Its services cover payroll calculations, HMRC reporting and records, while its wider platform brings together payroll, HR and time-and-attendance functions.
The company also has a specific small-business offering aimed at startups and growing organisations, including employers with relatively modest headcounts.
This approach may be particularly relevant where payroll variables originate in time records, absences or other workforce systems. A business that only has a handful of fixed monthly salaries may not need that level of integration, whereas shift-based employers can have quite different requirements.
PayFit
Best suited to: Small businesses wanting cloud payroll and employee administration within one system.
PayFit combines payroll with HR-related functionality including leave, expenses and employee information. Its UK small-business service also covers HMRC RTI submissions and provides access to UK payroll support.
This makes it closer to a software-plus-service model than a traditional accountant simply collecting payroll changes by email each month.
That can be useful where managers want employees and payroll information held in a central system. Before switching, small employers should confirm who actually performs each task, how payroll is approved and what level of support is provided if an unusual payroll issue needs manual attention.
The Accountancy Partnership
Best suited to: Limited companies and smaller employers that want payroll as part of an ongoing accountancy relationship.
The Accountancy Partnership offers managed payroll as an add-on to its accounting packages. Its stated process includes requesting pay information each period, processing payroll, issuing payslips and summaries, and submitting RTI information to HMRC. It also describes support for starters, leavers, statutory payments, student loan deductions and workplace pensions.
The firm also has a London office while operating as an online accountancy provider.
This model is worth comparing with standalone payroll bureaux where an employer wants one accountancy practise to handle several compliance functions rather than maintaining separate providers for accounts and payroll.
PAYE and RTI Questions to Ask Before Appointing a Provider
An employer should not assume every payroll quotation includes the same work.
Ask first who prepares and submits the FPS. HMRC normally expects payroll information to be reported on or before payday, so the provider’s processing timetable needs to fit the company’s actual payment date.
Then establish how corrections are handled. Payroll information sometimes arrives late: an employee may report an incorrect tax code, a bonus may be approved after the cut-off, or hours may be submitted incorrectly. The contract should make clear what happens when payroll needs to be amended.
Other useful questions include:
Who handles starters and leavers?
Find out whether the provider prepares the relevant payroll records and documents or merely processes information supplied by the employer.
Are pension duties included?
Some payroll services calculate deductions but leave pension-scheme administration to the employer. Others offer wider pension support.
How are statutory payments processed?
Maternity, paternity, sickness and other statutory payments can require additional information and calculations.
Does the service include year-end administration?
Confirm responsibility for final payroll submissions and P60 production rather than assuming these are automatically included.
What are the payroll cut-off dates?
A technically capable provider is little help if the company’s managers routinely cannot supply variable pay data within its required timetable.
What Information Is Needed When Moving Payroll Providers?
Changing payroll companies is partly an administrative exercise and partly a data-transfer exercise.
A new provider may need employer PAYE details, employee information, payroll year-to-date figures, current tax codes, National Insurance information, salary or hourly rates, pension details, deductions and previous submission data.
The exact requirements depend on when the handover occurs and how the outgoing payroll was maintained.
Accuracy matters because payroll is cumulative. Incorrect opening balances can affect later calculations and reporting even where the new provider processes subsequent pay periods correctly.
Employers should also plan how ongoing changes will reach the payroll team.
A simple monthly payroll might need only confirmation that salaries are unchanged. A hospitality, retail or shift-based employer could instead be supplying variable hours, overtime, bonuses, sickness, holiday information and new starters every pay cycle.
The handover process should therefore establish a repeatable workflow rather than simply transfer historical records once.
Data Security Should Be Part of the Payroll Comparison
Payroll files contain substantial personal and financial information.
Names, addresses, pay, bank details, National Insurance numbers and other employment records may all pass between an employer and its payroll provider.
HMRC specifically reminds employers that businesses storing or using personal information must follow applicable data-protection requirements.
Prospective providers should therefore be asked how information is transferred, who can access payroll records, how employee documents are distributed, and what happens to data when the relationship ends.
For small employers that currently email unprotected spreadsheets between managers, moving to an external provider can also be a useful opportunity to redesign the information flow rather than reproducing the same informal process elsewhere.
Choosing the Right Payroll Provider for a Small Business
The most suitable provider is determined less by brand recognition than by how well its operating model matches the employer.
A five-person consultancy whose staff receive fixed monthly salaries may want something simple: monthly calculations, payslips, RTI submissions and year-end documents.
A restaurant with weekly pay, changing hours and frequent starters may prioritise deadlines, variable-pay handling and integration with time records.
A technology startup might prefer payroll integrated with HR software. A director-managed company may instead find it more convenient for its accountant to deal with payroll alongside bookkeeping, Corporation Tax and annual accounts.
Pricing also needs to be compared on the same basis. Ask whether the quoted fee changes with employee numbers, pay frequency, additional payrolls, starters and leavers, pension work or year-end administration.
Finally, consider communication. When payroll goes wrong, the issue usually needs resolving before employees are paid. Knowing who answers questions and how quickly unusual changes can be dealt with is therefore as important as the standard monthly workflow.
The Better Payroll Decision Starts With the Process, Not the Provider
Small employers have considerably more choice than simply running payroll themselves or sending a spreadsheet to an accountant.
London businesses can choose from specialist payroll bureaux, accountancy firms, managed payroll companies and cloud platforms that combine payroll with HR administration.
The useful comparison is therefore not which provider has the longest feature list. It is which service matches the way the employer actually pays and manages its people.
Before outsourcing payroll, map the current process from employee changes through to payday, HMRC reporting and accounting records. Identify which stages should move to the provider and which will remain internally controlled.
Once those responsibilities are clear, comparing payroll accountants, payroll bureaux and technology-led services becomes much more straightforward, and the resulting payroll arrangement is far more likely to fit the business as its workforce changes.
