Run UK payroll
in minutes.
PAYE, National Insurance, RTI and auto-enrolment, all handled for businesses with 1 to 50 employees. Run payroll in minutes and file to HMRC with confidence.
RTI and auto-enrolment handled. P45s, P60s and statutory pay, done for you.
Everything a UK pay run needs
Payroll OS takes a business from starter details to filed submissions. Every part of a compliant UK pay run is built in, so nothing is left to a spreadsheet.
PAYE and NI, calculated
Income tax and National Insurance worked out for every employee, every pay run, to current HMRC rates.
RTI FPS and EPS filing
Full Payment Submissions and Employer Payment Summaries prepared and filed to HMRC on schedule.
Auto-enrolment handled
Assessment, enrolment, opt-outs and pension contributions managed against the current thresholds.
Statutory pay
Sick pay, maternity, paternity and other statutory payments calculated and applied correctly.
P45s and P60s
Starter and leaver paperwork and year-end P60s generated automatically when they are due.
Filed right the first time
Payroll is unforgiving, so accuracy is built into every run, not bolted on afterwards.
Every calculation passes a 612-vector accuracy gate against HMRC 2026/27 rates. Nothing is filed to HMRC until a human quality check signs it off, so RTI submissions go in right the first time and stay auditable.

Payroll questions, answered
What is RTI and do you handle it?
Real Time Information is how employers report pay and deductions to HMRC on or before each payday. Payroll OS prepares and files your Full Payment Submissions and Employer Payment Summaries automatically, so every submission lands on time.
How does auto-enrolment work?
Every worker is assessed against the current earnings thresholds each pay run. Eligible staff are enrolled, contributions are calculated, and opt-outs and re-enrolment are tracked for you, in line with the rules.
Can it handle statutory sick and family pay?
Yes. Statutory sick pay, maternity, paternity, adoption and shared parental pay are calculated to the current rates and applied to the right pay runs, with the qualifying checks built in.
How hard is it to switch from my current provider?
Switching takes minutes. Bring your year-to-date figures and employee details, we load them, and your next pay run continues without a break. Most micro-employers are up and running the same day.
Is my payroll data secure?
Your data sits behind row-level security, encrypted key storage and strict access controls, and it stays in our platform. It is never sold on or handed to third parties.
How do you make sure filings are accurate?
Every run passes a 612-vector accuracy gate against HMRC 2026/27 rates, and a human quality check signs off before anything is filed. That keeps RTI submissions right the first time.
