Managed payroll, run by specialists, with you in control
Hand your payroll to Nxsys. A named payroll specialist runs every pay run end to end on our own platform, from inputs to payslips, statutory submissions and bank files. We ask for your approval only when it's needed, and you see everything as it happens. For organisations in the United Kingdom and Ireland.
Everything a pay run needs, handled for you
We take on the whole payroll cycle, not just the calculation. You send changes, and we deliver an approved, filed and paid payroll.
Pay run processing
We collect inputs, process gross to net, check the results against your previous period and send the pay run for your approval when it's needed.
Statutory submissions
We file RTI with HMRC in the UK and payroll submissions with Revenue in Ireland, on time, every period.
Pensions
We run auto-enrolment in the UK and My Future Fund in Ireland, including assessments, contributions and provider files.
Payslips and documents
Employees get payslips, P60s and other documents in the Nxsys app and portal, white-labelled with your brand if you wish.
Starters, leavers and changes
We set up new starters, process leavers and apply pay changes, so records stay right between pay runs.
Year end and reporting
We handle year-end tasks and give you the reports finance needs: payroll journals, cost-centre reports and pension summaries.
The same five steps, every pay period
Send hours, starters, leavers and pay changes by spreadsheet or through the API, or enter them in Nxsys.
Your specialist runs gross to net on the Nxsys engine, then checks variances against the previous period and flags anything unusual.
We send you the draft payroll for approval only when it's needed. The summary and reports are always in the employer portal.
We confirm the payroll, download the bank file and pay your workers on your behalf. Payroll data is needed six hours before payments.
Payslip emails go out and employees view them in the app. We file with HMRC (FPS, EPS and CIS where applicable) or Revenue, send pension files and your custom report.
You do
Your part of each pay run is short and clear.
We do

Your first live pay run, with your named specialist on hand.
Moving mid-year? We bring over year-to-date figures, so you don't need to wait for the tax year end.
One service, two countries
The service is the same in both countries. Only the statutory work differs, and we handle it.
United Kingdom
RTI with HMRC, PAYE, NI, auto-enrolment pensions, statutory pay and CIS where needed.
Ireland
Revenue payroll submissions, PAYE, PRSI and USC, My Future Fund, RPNs and RCT where needed.

Built for organisations that want payroll off their desk
Growing businesses
No payroll team yet, or one person covering it. We run it, and check with you when a decision is needed.
Mid-size and enterprise
Several entities, pay schedules and approval steps, run by one team that knows them.
In-house teams under pressure
Cover for a team stretched by growth, leave or a system change, without hiring.
UK and Irish operations
Run both countries' payrolls with one provider and one service agreement.
Use the Nxsys platform with your own team, and move to the managed service later without changing system.
Who does Nxsys work with?
Nxsys is built on trusted platforms and connects with pension providers, ID checks, compliance partners and the HR tools your team already uses.

“The candidate onboarding via the app is a real asset to our business.”
01What is a managed payroll service?
It is payroll run for you by a provider. With Nxsys, a named specialist runs every pay run on our platform, and asks for your approval whenever a decision is needed.
02How is it different from using Nxsys software?
With the software, your team runs payroll in Nxsys. With the managed service, our specialist runs it on the same platform and checks with you when a decision is needed. You can move between the two without changing system.
03Do we stay in control?
Yes. You can see every change, payslip, report and submission in the employer portal, and we ask for your approval whenever a decision is needed.
04Do you file with HMRC and Revenue?
Yes. We file RTI with HMRC for UK payrolls and payroll submissions with Revenue for Irish payrolls, every period.
05Can you run both UK and Irish payrolls?
Yes. We run both from one platform, under one service agreement.
06How long does it take to move to Nxsys?
It depends on the number of entities and integrations. Your onboarding lead agrees a plan with you, including a parallel run before go-live.
07Can we move mid-year?
Yes. We bring over year-to-date figures from your current system.
08Who answers our employees' payslip questions?
Employees see their payslips in the Nxsys app. Queries go to your HR team or to our specialists, depending on the service you choose.
09How is the managed service priced?
It is quoted for each organisation, based on the number of employees, entities and pay frequencies. Speak to Nxsys for a proposal.
10How do you keep our data secure?
Nxsys is certified to ISO 27001 and Cyber Essentials, and data is encrypted in transit and at rest. Your security team can request our security pack.
