Moonworkers is a UK payroll platform for growing businesses and developers. It is listed as HMRC-recognised software, which means it meets HMRC's technical requirements for submitting payroll data and is approved to send Real Time Information (RTI) submissions directly to HMRC on your behalf.
Moonworkers offers two main products:
Payroll Software — a web application at payroll.moonworkers.co.uk for employers who want to run payroll themselves. It handles PAYE calculations, National Insurance, pensions, statutory pay, and RTI submissions with no manual steps required.
Payroll API — a REST API at payroll-api.moonworkers.co.uk for software developers and payroll bureaus who want to embed UK payroll calculations into their own applications. The API covers the full payroll calculation engine including PAYE, NI, CIS, directors' NI, zero-hours contracts, and all statutory payment types.
There is also Instant Payslip, a one-off payslip generator at online-payslips.moonworkers.co.uk/generator that requires no account or subscription.
Moonworkers is a UK-based company. Support is available in English.
