Not a cut-down bureau tool

You get the multi-client dashboard — and every client gets the entire Mellow platform

Old bureau software just processes payroll. Mellow Practice adds the cross-client dashboard on top of the complete Mellow platform — so every company you manage gets all 19 modules, the AI team, six-country payroll and the intelligence suite. That’s how a payroll bureau becomes a people-advisory practice.

Payroll bureau software — questions answered

What is payroll bureau software?
Payroll bureau software lets an accountant, bookkeeper or payroll service provider run payroll for many client companies from one place. Mellow Practice adds a multi-client dashboard on top of the full Mellow HR & payroll platform: one login, switch between clients, and run payroll for any of them.
What are the benefits of Mellow Practice for a payroll bureau?
Three concrete benefits: (1) One login for every client — manage all your client companies from a single dashboard, switch in to run payroll, switch back, instead of a separate tool and login per client. (2) Turn payroll into advisory revenue — every client gets AI assistants for employment law, IR35, pensions and right-to-work, plus computed tribunal-risk scoring, WorkloadSense and gender pay gap reporting, so you can sell people-advisory services without hiring an HR team. (3) One platform for the UK and Ireland (and four more countries) — UK PAYE/NI/RTI and Irish Revenue PAYE/USC/PRSI run side by side, so you never need a second payroll system.
Does Mellow Practice support UK and Ireland payroll?
Yes. Every client gets real payroll — UK PAYE, National Insurance and RTI, and Irish Revenue payroll with PAYE, USC and PRSI — plus the US, UAE, India and Australia. You can manage UK and Irish clients side by side from one dashboard.
How is Mellow Practice priced?
Flat per-practice pricing, not per client: Practice Starter £99/month (up to 5 clients, 100 employees), Professional £249/month (25 clients, 500 employees) and Enterprise £499/month (unlimited). Annual plans get two months free. There is a £2/employee/month charge above your plan’s included headcount.
Is Mellow a BrightPay Bureau, Sage Bureau or Moneysoft alternative?
Yes. Unlike traditional desktop bureau tools, Mellow Practice is cloud-based, covers HR as well as payroll, runs six-country payroll, and includes AI agents for employment law, IR35, pensions and right-to-work — so you can offer advisory services, not just process payroll.
Can a payroll bureau offer HR advisory with Mellow?
Yes — that is the point. Every client gets computed WorkloadSense, tribunal-risk scoring and gender pay gap reporting, plus AI assistants for employment law, IR35, pensions and right-to-work, so a bookkeeping or payroll practice can offer people-advisory services without hiring an HR team.
How do I start a payroll bureau with Mellow?
Register a practice at /register/practice, add your client companies (UK, Ireland and four more countries), invite your team with the right roles, and start running payroll. You can be operational in minutes.
