Enterprise payroll software for UK employers and groups
HMRC-recognised payroll for UK employers with up to 100,000 employees per payroll, across every company and PAYE scheme in your group. Certified security, approvals on every pay run and resilient data protection come as standard.
One payroll platform for complex organisations
Nxsys runs payrolls from 1 to 100,000 employees on the same cloud platform, across as many companies, pay schedules and sites as your group needs.
Multi-entity by design
Run every company in the group from one account, each with its own employer registration, pay schedules and approvers, and report across the group.
Approvals before anything is paid
Pay runs move through approval workflows you define, so nothing is finalised or paid without sign-off from the right people.
Bulk processing at scale
Run, finalise and submit pay runs for many entities in one batch, with payroll by exception so your team only reviews what changed.
Payment integrity
Bank account verification checks payee details before salaries are paid, which cuts payment errors and fraud risk.
Compliance on every payday
Submissions to HMRC go on or before every payday, with tax notices applied automatically.
Employees serve themselves
New starters onboard in the Nxsys Payroll app with ID verification, contract signing and documents, then see their payslips there every pay day.
Security that stands up to procurement
Payroll holds your most sensitive data. Nxsys is independently certified and gives your IT and security teams the controls they expect from enterprise software.
Independently certified
Nxsys is certified to ISO 27001 for information security management, and to Cyber Essentials.
Identity and access
Single sign-on with your identity provider, and role-based access that limits each user to the entities, departments and data their role permits.
A full audit trail
Every change to employees, pay and settings is logged with who made it and when, ready for internal and external audit.
Encryption throughout
Payroll data is encrypted in transit and at rest, including backups.
Verified people, verified payees
ID verification at onboarding and bank account verification before payment protect both your employees and your payroll.
Data protection
Personal data is processed in line with UK GDPR and the Data Protection Act 2018, under a data processing agreement with your organisation.
Your security and procurement teams can request our security pack: certificates, policies, our data processing agreement, hosting details and recovery objectives.
Your payroll data is backed up, protected and recoverable
Pay day cannot wait for a recovery. Nxsys is built so that payroll data survives mistakes, outages and incidents, and can be restored quickly and accurately.
Payroll data is backed up automatically, with no action needed from your team.
Backups are encrypted and kept apart from the live service, so one incident cannot affect both.
Records changed or deleted by mistake can be restored to an earlier point in time.
Restores are tested regularly under our ISO 27001 controls, and every restore is recorded.
Business continuity
Documented business continuity and disaster recovery plans keep payroll running, and are reviewed as part of our ISO 27001 certification.
Nothing drops out of the record
Every pay run, payslip, submission, report and audit entry is kept for at least the three years HMRC requires.
Your data stays yours
Export employee, pay and report data whenever you need it, including at the end of your contract.
UK payroll compliance, handled at enterprise scale
Every entity and PAYE scheme stays compliant with HMRC, automatically.
RTI on every payday
Full Payment Submissions and Employer Payment Summaries go to HMRC for every PAYE scheme, on or before payday.
HMRC notices applied daily
P6 and P9 tax code notices and student loan notices are checked daily and applied to the right employee.
Auto-enrolment
Workplace pension assessment, contributions and reporting are handled in payroll, with NEST, Smart Pension and NOW: Pensions connected.
Statutory pay
Statutory sick, maternity, paternity, adoption and shared parental pay are calculated in the pay run.
CIS for subcontractors
Construction Industry Scheme deductions and returns run alongside employee payroll.
Year end
P60s for every employee and year-end reporting to HMRC, across every entity in the group.
Connected to the rest of your enterprise
Keep payroll in step with HR, finance and workforce systems, without re-keying data.
Open API
Create and update employees, post pay elements, and retrieve results and reports through the Nxsys API.
HR and workforce systems
Employee changes and hours flow in from your HRIS, rota and time systems through the API and integrations.
Finance journals
Post payroll journals to your finance system, with cost centres and entities mapped once.
Import mapping
Load data from any file layout. Map the columns once and reuse the mapping every pay run.
Single sign-on
Users sign in with your identity provider, so joiners and leavers are managed in one place.
Pensions and compliance
Contributions and reporting connect to workplace pension providers such as NEST, Smart Pension and NOW: Pensions.
