Umbrella payroll software with a contractor app that does the onboarding for you
With the Nxsys contractor app, contractors onboard themselves on their phone: they verify their ID, sign their contract, upload documents and message you and their agency in one place. Behind it, Nxsys runs compliant umbrella payroll in the UK and Ireland and connects to your agencies through APIs. Choose your country for local compliance and pricing in your currency.
How does umbrella payroll work?
An umbrella company employs contractors who work through recruitment agencies. The end client pays the agency, the agency pays the umbrella the assignment rate, and the umbrella runs payroll as the employer: it deducts its margin, income tax, social insurance and pension, makes the statutory submissions to the government, then pays the contractor a net salary with a full payslip. Nxsys runs every step of that flow in one system.

How does a contractor go from invite to first payslip?
Create
Your team creates the employee or contractor with their name and email address, or the agency creates a prospect in the agency portal.
Invite
You invite the contractor to onboard themselves in the app, where they complete their details, verify their ID and right to work, and sign their contract.
Work
Timesheets and remittances arrive from the agency through the API or import mapping.
Pay
Nxsys deducts your margin, processes expenses and holiday pay, checks the minimum wage, pays the contractor and makes the statutory submissions.
Stay in touch
The payslip appears in the app, and any questions go through three-way messaging.

The Nxsys contractor app on iPhone and Android.
Onboard yourself
Contractors enter their personal, bank and tax details, verify their ID and right to work, and sign their contract on screen. Bank and address checks catch errors before the first pay run.
Manage your profile
Contractors view and update their own details in the app, so your team spends less time on change requests.
View your payslip breakdown
Each payslip shows gross pay, tax, social insurance, pension and net pay, so contractors can see how their pay was worked out.
Compare your payslips
Contractors can compare pay periods and see what changed, which means fewer "why is my pay different?" calls.
Message your agency and/or umbrella
Three-way messaging puts the contractor, your team and their agency in one thread, with a full history of every pay query.
Perks and benefits
Contractors see the perks and benefits you offer in the same app they use for their payslips.
The app carries the Nxsys brand as standard. A white-label version in your umbrella's branding is available as an optional extra.

Compliance on every pay run
Minimum wage, right-to-work and working time checks run as part of payroll, with the local rules for each country.
Connected to your agencies
