How does Mellow work?

Mellow is AI-native HR and payroll software built around a single record of each employee. It runs native payroll and local compliance across six countries — the UK, Ireland, the USA, the UAE, India and Australia — and handles absence, onboarding, pensions and documents in one place, with AI assistants that draft documents, answer questions and explain the figures Mellow computes from your data and the legislation. Accountants and payroll bureaus can use Mellow Practice to manage many client companies from one login. Pricing starts at £4 per employee per month, with a 14-day free trial.

Mellow vs People HR: AI-native vs traditional

Mellow HR Team·2 min read

People HR (now part of the Access Group) is a UK HR platform that has been in the market for over a decade. It covers core HR functions — employee records, absence, performance, and recruitment — with a UK-first approach and a familiar interface. The comparison with Mellow is partly about features and partly about the philosophical difference between a traditional HR system and an AI-native one.

Core HR

People HR is a solid traditional HR platform. Employee records, absence tracking, performance management — it covers the bases. It has been built for UK employers, understands UK employment law, and has a stable, proven product. For businesses that want reliable, well-understood HR tools, it is a reasonable choice.

Payroll

People HR does not include native payroll. The Access Group ecosystem includes Access Payroll, but these are separate products that are sold and integrated separately. Mellow includes UK payroll natively.

AI and intelligence

This is where the most significant difference lies. Mellow was built as an AI-native platform from day one — not as a traditional HR system with AI features bolted on. Mellow's Intelligence tier includes WorkloadSense (real-time workload monitoring), predictive compliance (flagging ERA 2025 obligations before they breach), tribunal risk scoring, pay equity analysis, and AI agents that can answer employment law questions in the context of your specific workforce data.

People HR has been adding AI features to its existing product. That is a different thing from designing a platform around AI intelligence from the start.

ERA 2025

Both platforms have been updating for ERA 2025. Mellow's Predictive Compliance tracks the Employment Rights Act 2025 changes at a configuration level; People HR offers compliance documentation and guidance.

Pricing

People HR pricing is competitive in the mid-market. When payroll is included in the comparison, Mellow's Professional tier offers better value for most UK businesses of 50 to 250 employees.

The honest view

For a business that wants a proven, stable HR system and is comfortable managing payroll separately, People HR works. For a business that wants AI-native HR intelligence and native payroll integration as the platform grows, Mellow is the stronger long-term choice.
