Run payroll properly in six countries —
with the UK Employment Rights Act, mapped and automated.
Accurate payroll and local compliance across the UK, Ireland, the USA, the UAE, India and Australia — automated. In the UK that means the Employment Rights Act 2025 mapped end-to-end, so 2026/27 can’t catch you out. Plus an early-warning radar for the overload that becomes a tribunal claim.

One connected platform
Change it once.
It's right everywhere.
Most HR runs on a tangle of tools that never quite agree — payroll says one thing, the spreadsheet says another, and someone loses Friday to reconciling them. Mellow is one platform around a single employee record. Update someone once, and payroll, pensions, leave and reporting are all right in the same moment.
One employee record
Not five spreadsheets
Zero re-keying
Change flows everywhere
Always current
Every report, in real time
Built to connect. Mellow has a full public REST API and webhooks, so it plugs into your stack — accounting, finance, BI and bespoke tools. Direct app integrations are on the roadmap; the API is available today. See the API docs →
Intelligence built in
AI assistants that do the work.
Real assistants that understand each country's employment law, your employee data and your company — and answer in seconds, accurately. Up to a People Coach that helps managers handle conflict, team health and tough conversations — grounded in your real data, not generic advice.
Mellow computes the numbers — from your data and the legislation, never guessed. The AI is how you ask it questions and how it explains itself; it never invents a figure.

WorkloadSense · overload & tribunal-risk radar
See who's overstretched before it becomes a tribunal claim
Chronic overload is where grievances, burnout and tribunal claims begin. WorkloadSense fuses workload, hours and retention risk into one read — so you see who's overstretched andhard to replace, and act before it escalates.
And cutting deep rarely pays: the layoff-era evidence is blunt — around 55% of employers who make heavy cuts regret them, and roughly two-thirds rehire for the same roles within a year. See the strain before you lose the people you can't replace.
