Outsourcing can be a huge relief when you lack the staff or expertise to manage your payroll, especially if you’re a small business. As your company grows, you might find that bringing your payroll in-house becomes a more viable option—or you may prefer to continue outsourcing for efficiency or compliance reasons.
This post explores the benefits of bringing payroll in-house, from how it differs to outsourcing and why you would consider it, to how to proceed with making the switch.
What is in-house payroll?
In-house payroll does exactly what you would expect—it’s when your payroll process is managed internally by your own team, using in-house payroll software rather than being managed by a third-party provider. The people who process the payroll are classed as internal employees, so they are paid through the same system they help manage.
Payroll software lets you:
- Automate and manage all internal payments,
- take care of any HMRC deductions,
- handle bonuses, benefits, and expenses,
- deal with any statutory payments,
- and build the necessary reports needed to submit to HMRC.
The alternative to this is payroll outsourcing where instead of having full control over your payroll, you allow a third party to manage the process for you.

The pros and cons of in-house payroll
So, if you’re debating bringing your payroll internally, you need to see the good, as well as the potential bad. After all, payroll is at the heart of every organisation, so finding the right fit for your business—and your people—is vital.
Let’s look at the pros and cons of in-house payroll:
| Pros | Cons |
|---|---|
| Full transparency and control: You can see and adjust every part of the payroll process. | Time investment: Implementation and ongoing management require internal resources. |
| Automation: From handling calculations and deductions to updating to reflect legislative changes and flagging errors, in-house software significantly reduces the margin for error. | Need for expertise: Your teams need to be payroll pros to avoid any costly fines, so your staff need to be trained. |
| Integration: In-house software often integrates easily with HR, accounting, and expense management tools reducing data duplication. | Added compliance responsibility: Responsibility for accuracy and deadlines shifts fully to your business. |
| Improved employee experience: Issues will be resolved faster as they are handled internally as they arise. This builds trust as your employees know that queries are handled quickly. | Overly centralised process: You might only have one payroller in your team, so it can create risks for your payroll not going ahead. |
When is the right time to consider bringing your payroll in-house?
There’s no definitive answer as to when you should consider managing your payroll internally. But there’ll be signs that it might be time to change your processes.
Your business has grown enough to warrant dedicated payroll staff
In most instances, outsourcing your payroll comes in as a response to a problem. Whether it be lack of expertise, time, or knowledge.
Say your company started with only 20 employees, payroll outsourcing can help to plug any gaps in expertise and help to save time. But if your company now employs over 200 employees that branch across several departments, you may begin to need more control over pay structures, benefits, and reporting.
If you can comfortably employ multiple people to manage it, it makes sense to bring your payroll in-house. Handling payroll in-house gives you the ability to customise processes and respond to changes quickly.
You need greater flexibility
Say you need to run off-payroll cycles or make an adjustment quickly before the payroll runs, with an outsourced provider, these changes can be slower or even, more expensive to make. In fact, with many outsourced providers, it can require 3-5 days’ notice to process. By bringing your payroll in-house, it allows you to run payroll on your schedule. That means making any adjustments instantly and handling any last-minute changes without any delays or hold ups.
You want to align payroll closer to HR and culture
You’ve recently implemented new HR and finance systems and want payroll data to flow seamlessly between them. With in-house software can sync with HR and accounting tools, supporting a connected people strategy where payroll is part of your wider company culture, not an outsourced process. Providers like Cintra also offer an integrated hr and payroll software that helps you to align the two within one single platform, minimising data duplication and creating a single source for people data.
Some will also offer a self-serve option too, allowing employees to take control of their own data (like address changes and updating telephone numbers) and access their own payslips or internal letters. It all helps to create a culture where employees feel empowered to control their own data—all the while making sure everything runs smoothly and with total accuracy.
How do you bring your payroll in-house?
So, if any of this sounds like your current situation, you’re probably wondering how you can go about making it happen. We’ve covered the steps you can take to bring your payroll process in-house. Looking for a more in-depth look into how payroll software works specifically? We’ve got that too in our How does Payroll Software Work post.
1. Get internal approval
Start by building your business case. While the benefits of in-house payroll might be clear to you, it’s important that your leadership teams understand these benefits too. Include a clear breakdown of costs and benefits—from software licensing and training to the long-term savings of managing payroll yourself.
2. Define your payroll setup
Next, you need to decide how your payroll will operate internally. Will you have a dedicated payroll team, or will it sit within existing teams, like HR or finance?
Be clear on who’s responsible for processing, approvals, reporting, and compliance to avoid confusion later. It’s also a good time to assess whether your team needs extra training or support before you make the switch.
3. Choose the right provider
What software you choose will make or break your in-house payroll, so it’s important to look for a system that’s recognised by HMRC and kept up to date with the latest legislation.
Automation is also a big plus. After all, the less manual work, the fewer errors you’ll face. Integrations with HR, time, and accounting systems can also save hours of admin, too.
Don’t just compare prices; focus on reliability, reporting flexibility, and the level of support you’ll get post-implementation. If you’re looking for the right payroll software provider, look no further than Cintra—we offer all these features (and more).
4. Migrate your payroll data
Once you’ve chosen your software, the next step is data migration.
You’ll need to import all relevant employee information—personal details, tax codes, salaries, deductions, and benefits—as well as historical data for at least the current and previous tax year.
Always run test payrolls before you go live to make sure everything lines up correctly. A secure, encrypted transfer process is essential to protect sensitive employee data.
5. Stay compliant
When payroll is in-house, compliance is your responsibility.
That means staying on top of RTI submissions, auto-enrolment duties, and statutory payments like SSP and SMP. You’ll also need to issue accurate payslips and maintain payroll records for the legally required period (a minimum of 3 years in the UK).
Make sure your team knows how to handle data securely under GDPR and be prepared to review your setup regularly to keep up with legislative changes.
6. Let your teams know
Congratulations, you’ve made it to the penultimate step of the process. Transparency is always key when making any big business changes, so don’t forget to share the good news. Make sure you let your team know that payroll will now be done internally, and any other relevant changes that impact them.
7. Keep improving
After a few months, review your setup.
This means gathering feedback from the payroll team and employees to see what’s working well and what could be improved. Regular reviews help keep your payroll processes compliant, efficient, and aligned with the needs of your growing business. Just because it’s beneficial doesn’t mean it will work for your team. So, be prepared to tweak and change your process if it’s not the right fit.
Why some businesses choose to stay outsourced
While bringing payroll in-house can offer more control, many organisations find that outsourcing remains the most efficient and reliable approach—especially as their needs evolve. Outsourcing doesn’t just remove the administrative burden; it can also provide valuable peace of mind.
Here are some reasons why businesses continue to outsource their payroll:
- Expertise and accuracy: Outsourced providers are payroll specialists who stay up to date with the latest legislation and compliance requirements, reducing the risk of costly errors or penalties.
- Time and resource savings: With an external team managing payroll, your internal staff can focus on core business priorities instead of routine processing or troubleshooting.
- Scalability: Outsourcing can flex with your business. Whether you’re expanding rapidly or have seasonal fluctuations in headcount, a provider can adjust capacity without adding to your overheads.
- Technology and data security: Many payroll providers invest heavily in secure, cloud-based systems that protect sensitive employee data and provide reliable disaster recovery options.
- Consistent service: Even if key internal team members are absent or leave the business, outsourced payroll ensures continuity and avoids delays in paying staff correctly and on time.
