Outsourced payroll should be more than data entry. Our team owns the whole process: gross-to-net calculations, RTI submissions, auto-enrolment, statutory pay, CIS, year-end returns and every HMRC conversation in between. You approve the numbers; we do everything else.

Whether you pay two people monthly or hundreds weekly, you get the same service: a named payroll contact who knows your business, secure cloud payslips for your staff, and reporting that drops straight into your accounts.

Common Questions

Frequently Asked Questions

How do we switch our payroll to Acumon?

More easily than most employers expect. We collect your existing payroll data and year-to-date figures, rebuild the payroll on our systems and run it in parallel with your current arrangement until the numbers match to the penny. You can switch at any point in the tax year — a new tax year is the tidiest moment, but mid-year transfers are routine for us and most clients are fully live within one pay cycle.

What does CIPP-qualified mean, and why does it matter?

The Chartered Institute of Payroll Professionals is the UK's professional body for payroll. All of our payroll staff hold CIPP qualifications, which means the people running your payroll are formally trained in UK payroll legislation and keep that knowledge current — rather than simply typing numbers into software and hoping the defaults are right.

Will our employees notice the change?

Only in good ways. Employees receive secure cloud payslips they can access at any time, with historical payslips archived online, and their pay arrives as normal. Net pay should not change simply because the payroll provider has — and our parallel-run process during onboarding is designed to prove exactly that before we go live.

Can you handle complex payrolls — CIS, tronc, IR35 contractors or internationally mobile staff?

Yes. Alongside standard payrolls we run CIS for construction businesses, tronc arrangements for hospitality, off-payroll working and IR35 assessments, tax equalisation for international assignees, and UK payroll setup for overseas businesses bringing staff to the UK. Complexity is the reason many clients move to us in the first place.

How is our payroll data kept secure?

All processing happens in the UK by our own staff. Data is exchanged through secure channels rather than unprotected email, payslips are delivered through an encrypted online portal, and access to your payroll is restricted to your named payroll team, in line with UK GDPR obligations.

What happens at payroll year end?

We file the final Full Payment Submission of the year, produce and distribute P60s to all employees by 31 May, prepare P11Ds for benefits in kind by 6 July where required, and roll your payroll into the new tax year with updated thresholds, rates and tax codes applied. For our clients, year end is just another month.
