Quick answer: A payroll bureau handles selected parts of your payroll, such as payslips or expenses, while your in-house team runs the rest. Outsourced payroll hands the whole process to a provider, from calculations and deductions to Real Time Information (RTI) submissions and employee payments. A bureau suits organisations with in-house payroll expertise that want to keep more control. Outsourcing suits organisations that want to reduce cost, risk and workload. With either model, the employer stays legally responsible for its PAYE obligations to HMRC.

The way you choose to handle your payroll has a significant impact on efficiency, compliance, and success. Two common options stand out: the payroll bureau and outsourced payroll services.
And while both serve the same fundamental purpose of paying employees accurately and on time, they are distinct in their approach and the level of involvement they require from you. So, let’s explore the key differences between the two solutions, helping you make an informed decision about which one is best suited to your needs!
Key takeaways:
- Payroll bureau (part-managed payroll): You run payroll partly in-house and outsource specific tasks to a third party. You keep more control, but also more of the work.
- Outsourced payroll (fully managed payroll): A provider runs your whole payroll process from start to finish, reducing your workload and the compliance burden on your team.
- Cost: Outsourced payroll often works out cheaper than running an in-house team, as you’re not covering payroll salaries or software. It’s worth comparing quotes against your own costs, though.
- Compliance: With a bureau, you share the compliance work. With outsourced payroll, the provider takes it on day to day. Either way, you’re still legally responsible for your PAYE obligations.
- Best fit: Choose based on your in-house expertise, how much control you want, your appetite for risk and your budget.

A quick note on terms: In this article, “part-managed payroll” and “co-managed payroll” mean the payroll bureau model, while “fully managed payroll” and “full-service payroll” mean outsourced payroll. Not every provider uses these terms the same way, though (more on that below).
What is a payroll bureau?
Payroll bureau: A hybrid model where you run payroll partly in-house and outsource specific tasks to a third-party provider, keeping control over the rest.
With a payroll bureau, you run part of your payroll in-house and hand certain tasks to a third-party provider. Rather than running the whole process yourself, you keep control of some of it and outsource the rest. You still employ your payroll team, set their hours and oversee the processes.
That means you keep more control, while your provider handles some elements, such as printing payslips or processing expenses.
It’s worth knowing that the language around payroll bureaus isn’t always used consistently, so check exactly what each provider is offering. Some outsourced providers call themselves payroll bureaus and vice versa. Some offer both types of service, while others offer a full package that looks a lot like outsourced payroll. The key is to get complete clarity from each provider before you sign.
The benefits of using a payroll bureau
If control matters to you, a payroll bureau lets you pick and choose which tasks to keep in-house and which to pass on. You could hand over the tasks you don’t have the skills for in-house, or the ones that take up the most time and effort, saving you time, cost or both.
With that time freed up, you might move your in-house team onto other work, or find you no longer need a full-time payroll team.
And just like outsourced payroll, a bureau gives you access to expertise in legislation, regulation and compliance.
The downsides of using a payroll bureau
Because you keep some payroll work in-house, you also keep the employment costs of your payroll team. That includes salaries, National Insurance, holiday and sick pay, benefits and more.
Your in-house team will still handle tasks like data collection, overtime calculations, administering pensions and anything else the bureau doesn’t cover. So if someone’s off sick (or even on holiday), there’s a real risk your payroll process stalls.
You’ll also still need the technology and payroll software to manage those tasks in-house, which can be a significant extra cost.
Then there’s the risk of mistakes. A bureau can’t reduce errors as much as a fully outsourced service, because some tasks are out of its hands. So when you keep part of your payroll, you keep part of the risk too.
What is payroll outsourcing?
Outsourced payroll: A full-service model where a third-party provider runs your whole payroll process from start to finish, handling calculations, compliance tasks and payments.
Outsourcing payroll means using a payroll service provider to manage your entire payroll.
The provider handles everything from start to finish. This is especially helpful if you don’t have internal finance, HR or admin teams, or if those teams need to focus on business-critical work.
Outsourced providers are experts in every part of payroll, including current and upcoming legislation. They keep things running even when the whole industry changes, as it did when RTI reporting and pensions auto-enrolment came in. They keep on top of the detail of payroll rules for you, taking a lot of the compliance burden off your shoulders. That said, HM Revenue & Customs (HMRC) still holds you, as the employer, legally responsible for your PAYE (Pay As You Earn) obligations, so it’s important to choose a provider you trust.
When you outsource, your main job is providing the data. Your provider will rely on you for information like starters and leavers, hours worked and bonuses. They’ll then handle the calculations, deductions, payslips, submissions, employee payments and everything else.
The benefits of using payroll outsourcing
Outsourcing your payroll will help to reduce your overall payroll costs. While outsourced services might not seem cheap at face value, when compare to the costs of employing your own in-house team, you’ll see significant savings.
You’ll also free up your time and resources internally, allowing you to put effort into the parts of your business that need it most—not just payroll.
Not forgetting the benefits of having a team of qualified professionals at your fingertips, ensuring service continuity. You’ll no longer need to worry about having the right knowledge internally, and can enjoy having the expertise of a company who fully understands the intricacies of payroll—and uses that expertise to keep your payroll accurate and compliant, minimising the risk of mistakes.
While there are many more benefits, we’ll finish on one of the most significant—preventing fraud. By adding a third-party into the payroll process, you lower the chances that attempted payroll fraud will go unnoticed, and creates a valuable separation in the process.
The downsides of using payroll outsourcing
One of the main worries organisations have about outsourcing payroll is the reliability of the provider, so choosing a reputable partner is essential. Take time to talk to providers and ask as many questions as you need to feel comfortable. Raise any unique requirements early on, so there are no surprises later that could affect the service. And find out whether they offer a service level agreement (SLA) or guarantee.
You should also talk about confidentiality and data security. Look for recognised certifications and accreditations, such as ISO/IEC 27001:2022, Cyber Essentials Plus and BACS Approved Bureau status, which show the provider takes security seriously.
Choosing between payroll bureaus and payroll outsourcing
Outsourcing part or all of your payroll is a big decision, so it’s important to choose the right approach for your organisation.
Take a close look at your current processes, procedures, costs and needs before making a change.
Choose a payroll bureau if:
- You already have payroll expertise in-house, but not quite enough resource to process everything efficiently.
- You want to keep more control over your payroll processes.
- You’d rather keep certain sensitive payroll tasks in-house.
- You have reliable cover in place for your in-house team.
Choose outsourced payroll if:
- Cost is a priority, as outsourcing is often the most cost-effective option once in-house costs are factored in.
- You’re concerned about keeping up with legislative changes, especially if you employ people on variable pay or minimum wage rates.
- You want to reduce your payroll risk as far as possible.
- You don’t have internal finance, HR or payroll teams to manage the process.
- You want to free up internal resources for business-critical work.

Frequently asked questions
Q. Is a payroll bureau cheaper than outsourcing?
A. Not always. Bureau fees may look lower, but you still carry in-house staff costs (salaries, National Insurance and benefits) plus software. Once those are factored in, fully outsourced payroll often works out cheaper overall, so compare total costs rather than fees alone.
Q. What tasks does a payroll bureau handle?
A. A payroll bureau usually handles the specific tasks you choose to outsource, such as printing and distributing payslips, processing expenses, producing reports or handling certain submissions. You keep control of tasks like data collection, overtime calculations and pension administration.
Q. Who is responsible for compliance in each model?
A. With a payroll bureau, compliance work is shared, and you’re responsible for the tasks you keep in-house. With outsourced payroll, the provider takes on the day-to-day compliance work, but you still need to supply accurate data. In both cases, HMRC holds you, as the employer, legally responsible for your PAYE obligations.
Q. Can I switch from a payroll bureau to fully outsourced payroll?
A. Yes. A lot of organisations start with a bureau model and move to fully outsourced payroll as their needs change. A reputable provider can help you manage the move smoothly.
