The Payroll Bureau Pricing Guide: What to Charge Your Clients

Getting your pricing right is the difference between a payroll bureau that survives and one that thrives. Charge too little and you are working hard for thin margins; charge without structure and you leave money on the table or lose clients to confusion. This guide covers how to price a payroll bureau's services in the UK and Ireland.

The standard bureau pricing model

Most bureaus use a two-part structure:

- A base fee per client per pay run — covering the fixed work of running and filing each payroll, regardless of headcount.

- A per-payslip fee — a charge for each employee processed, scaling with the client's size.

So a client with 20 staff paid monthly might be charged a base fee plus twenty per-payslip charges each month. This model is easy for clients to understand and scales fairly with the work involved.

Factors that should move your price

- Pay frequency. Weekly payrolls are roughly four times the work of monthly — price accordingly.

- Complexity. Multiple pay rates, shift differentials, tronc, statutory payments, and pension schemes all add work.

- Onboarding. Setting up a new client is real effort; many bureaus charge a one-off onboarding fee.

- Extras. P45s, year-end processing, auto-enrolment assessments, and ad-hoc reports can be bundled or charged separately. Be explicit about which.

Don't compete only on price

Pure processing is a commodity, and competing on price alone is a race to the bottom against automation. The bureaus with the healthiest margins price on value, not just volume — and the way to do that is to offer more than processing.

Packaging advisory for higher margins

Advisory services let you move beyond per-payslip economics. Consider tiered packages:

- Processing only — payroll run and filed, the commodity tier.

- Processing plus compliance — adds proactive compliance alerts and employment-law support.

- Full people partner — adds HR advisory, tribunal-risk insight, gender pay gap reporting, and workforce insight.

Each tier up commands a higher fee because it delivers more value and locks the client in more tightly. Platforms like Mellow make the higher tiers deliverable without hiring specialists, because the eleven practice-aware agents handle employment law, compliance, and people insight across all your clients.

Your own platform cost

When you set prices, account for your software cost. Mellow's practice pricing runs Starter £99/mo, Professional £249/mo, and Enterprise £499/mo, with annual billing giving two months free and an additional £2/employee/month over the included headcount; founding members get 50% off for life with code MELLOWPRACTICEFOUNDING2026. Build that into your per-client economics so every client is comfortably profitable.

Reviewing your prices

Set a calendar reminder to review pricing annually. Costs rise, complexity creeps up, and clients who started small grow. A bureau that never revisits its prices slowly erodes its own margin. A short, well-communicated annual review keeps the business healthy.

Price with a clear base-plus-payslip structure, charge fairly for complexity and extras, and — crucially — build advisory tiers that take you out of the commodity trap. That is how a bureau turns steady work into a genuinely profitable practice.
