Bureau payroll and small business payroll are not the same product with a different licence. A bureau runs many employers on many pay frequencies against a single set of deadlines, so the things that decide the software are batch processing, how quickly you can move between employers, whether the pricing model matches how your fees work, and how much of the repetitive checking the system does for you.
We have ranked these from the bureau side rather than the employer side: multi employer workflow, the depth a payroll professional actually needs, how the licensing behaves as your client count grows, and the real cost excluding VAT.
What a bureau should look for
The pricing model matters as much as the price. Bureau payroll is licensed in several quite different ways: per employer, per employee, per payslip, or in headcount bands across your whole book, and which one suits you depends entirely on the shape of your client base. A bureau with many very small employers is punished by per employer licensing and rewarded by per payslip. A bureau with a few large employers is the reverse. Model your actual client list against each vendor's structure before you look at the headline figure, because the same book of business can differ by thousands of pounds a year between two models that look similarly priced on the website.
Then judge the workflow, which is where bureau software either earns its keep or does not. You want to move between employers without re authenticating, run and check pay runs in batch rather than one at a time, and submit RTI across many employers without repeating the same steps for each. Look hard at the checking tools, because a bureau's real risk is a wrong payslip going out under your name: anomaly detection that flags an unusual net pay before you commit is worth more than any feature on a comparison table. Also weigh the client facing side, since employee self service and a portal for the employer to approve a run reduce the email traffic that consumes a bureau's day. Finally, confirm auto enrolment assessment is genuinely automated across all employers, not something you run per client each period.
How we assessed these tools
Every product here was judged on the things that actually decide whether software works for a UK business: the real published price excluding VAT, how it handles HMRC obligations such as Making Tax Digital, RTI or CIS where relevant, the depth of the core job it is bought for, how quickly a non specialist can get productive, and the quality of UK support. We read each vendor's own pricing pages rather than repeating third party figures, and we weight verified user ratings from people who run these tools day to day.
We also try to be honest about fit rather than crowning a single winner, because the right tool for a ten person business is rarely the right tool for a two hundred person one. Each entry below carries its real starting price, its current Assaylist rating and a clear note on who it suits and where it falls short, so you can match the software to your own situation rather than to an average. Where we earn a commission from an outbound link we say so, and it never changes the order of this list.
The best options ranked
1. BrightPay
BrightPay is the bureau favourite in the United Kingdom and deserves the reputation. The multi employer workflow is built for someone processing many payrolls to one deadline rather than adapted from a single employer product, and the batch handling and checking tools are what a payroll professional actually asks for.
What you get: A long standing favourite of UK and Ireland payroll bureaus, now moving fully to the cloud for the 2026/27 tax year. Deep, HMRC recognised, and built for people who run payroll for a living. It holds a 4.1 out of 5 rating across 235 reviews on Assaylist.
Pricing: The plans run BrightPay Cloud at a quoted price per month, excluding VAT.
Why we rate it:
- Trusted by a large share of UK bureaus
- Ready on day one of each tax year
- Strong multi employer processing
- HMRC recognised every year
Bear in mind: it is moving to cloud only for the 2026 and 2027 tax year, so long standing desktop users have a migration to plan.

2. IRIS Staffology Payroll
IRIS Staffology Payroll is the strongest fit where your client headcounts move around a lot, because the pricing flexes with volume rather than locking you into bands you have grown out of. It sits inside the wider IRIS stack, which matters if your practice already runs IRIS for tax and accounts production.
What you get: The cloud payroll engine from IRIS, one of the largest UK payroll and accountancy software groups. Priced on the number of payslips you process, which suits variable headcounts. It holds a 4.1 out of 5 rating across 223 reviews on Assaylist.
Pricing: The plans run From 1 to 19 payslips at £43 and 20 to 50 payslips at a quoted price per month, excluding VAT.
Why we rate it:
- Priced by payslip volume, not headcount
- Strong API for embedding payroll
- Backed by a major UK payroll group
- HMRC recognised
Bear in mind: IRIS has moved detailed pricing behind a demo form, so a firm quote now takes a conversation rather than a web page.

3. Sage 50 Payroll
Sage 50 Payroll is the long serving desktop bureau tool that a great many UK payroll staff already know inside out, and that familiarity is a real asset when you are hiring. The depth is there for complex payrolls, and the headcount band pricing is at least transparent about what growth will cost.
What you get: Sage's established payroll software for larger or more complex UK payrolls, priced in bands from 15 employees to unlimited. It holds a 4.1 out of 5 rating across 218 reviews on Assaylist.
Pricing: The plans run Up to 15 employees at £41, Up to 25 employees at £56.5, Up to 50 employees at £108.5, Up to 100 employees at £116 and Unlimited employees at £160.5 per month, excluding VAT.
Why we rate it:
- No limit on employee numbers
- Full auto enrolment assessment
- Pay run rollback and corrections
- Detailed statutory reporting
Bear in mind: the headcount bands step up as you grow, so check the band above the one you are buying before you commit.

4. Moorepay
Moorepay is the answer when the right decision is to stop running payroll yourself. It is a managed service with UK payroll and employment law support behind it rather than software you operate, which suits a practice that wants to offer payroll to clients without building the specialist capability in house.
What you get: One of the longest established UK payroll bureaus, offering managed and part managed payroll alongside HR support. A service as much as a piece of software. It holds a 3.9 out of 5 rating across 225 reviews on Assaylist.
Pricing: The plans run Managed payroll at a quoted price per month, excluding VAT.
Why we rate it:
- Payroll taken off your desk entirely
- Bundled HR and employment law advice
- Decades of UK bureau experience
- Managed compliance
Bear in mind: pricing is quoted to your requirements, so comparing it against a licence fee is not a like for like exercise.

5. PayFit
PayFit is the most modern experience here and the one clients themselves tend to like, combining payroll with employee self service in an interface that does not look like payroll software. For a practice whose clients want visibility and want to self serve, that reduces inbound queries noticeably.
What you get: A modern European payroll and HR platform popular with growing UK companies, combining automated payroll with light HR features. Per employee pricing on top of a base fee. It holds a 4.2 out of 5 rating across 245 reviews on Assaylist.
Pricing: The plans run Light at £29, Standard at £59 and Premium at £119 per month, excluding VAT.
Why we rate it:
- Heavy payroll automation
- Light HR bundled alongside
- Modern, clear interface
- Employee self service
Bear in mind: it is built primarily around the employer rather than the bureau, so the multi client workflow is lighter than a dedicated bureau tool.

How much should you budget?
Model your own client list rather than reading the headline. Bureau payroll is licensed per employer, per employee, per payslip or in headcount bands, and those structures produce wildly different totals for the same book of business. A bureau with forty employers averaging four staff each will pay very differently under per employer and per payslip licensing, and the cheapest looking vendor on a pricing page is frequently not the cheapest for you.
As a rough guide, bureau grade software for a small practice starts in the low hundreds of pounds a year excluding VAT and scales into the low thousands as your payslip volume grows. Sage 50 Payroll's bands begin around forty pounds a month at the smallest tier and rise with headcount. Fully managed services such as Moorepay are quoted entirely to scope and should be compared on total cost of delivery against your own staff time, not against a licence fee. Whatever you choose, budget for the annual legislative update and for the staff time your April changeover consumes, because both are certain and both are routinely left out.
Our verdict
For most UK bureaus, BrightPay is the strongest choice and has earned its position: the multi employer workflow, the batch processing and the checking tools are built for the job rather than adapted to it. Plan the move to its cloud product deliberately rather than leaving it to the last tax year, because that migration is now a question of when rather than whether.
IRIS Staffology is the better fit where client headcounts fluctuate or where your practice already runs IRIS elsewhere, and Sage 50 Payroll remains a solid, well understood option with the advantage that payroll staff already know it. If the honest answer is that payroll is not a capability you want to build, Moorepay's managed service is a legitimate strategy rather than an admission of defeat, and PayFit is worth considering where client experience is the thing you compete on.
The bottom line
Two decisions come before the software. First, whether you want to run payroll or have it run for you, because a managed service such as Moorepay is a different business model, not a more expensive licence. Second, which licensing structure fits the shape of your client base, since per employer, per payslip and banded pricing can differ by thousands a year on the same book. Once those are settled, BrightPay is the default recommendation for a bureau, with IRIS Staffology the alternative for variable volumes and Sage 50 Payroll for a team that already knows it.
Frequently asked questions
What payroll software do UK payroll bureaus use?
BrightPay is the most widely favoured bureau product in the United Kingdom, with IRIS Staffology and Sage 50 Payroll also common in practices. All three are built or adapted for processing many employers to a single deadline, which is the core requirement that separates bureau software from small business payroll.
How is bureau payroll software priced?
In several quite different ways: per employer, per employee, per payslip, or in headcount bands across your whole book. Which is cheapest depends entirely on the shape of your client base, so model your actual client list against each vendor's structure. Two products that look similarly priced can differ by thousands of pounds a year for the same practice.
Can payroll software submit RTI for multiple employers at once?
Yes. Bureau grade products let you run, check and submit across many employers in batch rather than repeating the process for each one, which is the main reason a bureau should not use single employer software. Confirm that auto enrolment assessment is also automated across all employers rather than run per client each period.
Should an accountancy practice outsource payroll instead?
It is a legitimate strategy. A managed service such as Moorepay provides UK payroll and employment law expertise without you building a specialist team, which suits a practice that wants to offer payroll without owning the risk. Compare it against the fully loaded cost of your own staff time rather than against a software licence.
What happens to bureau payroll software each April?
Every product updates for the legislative changes that take effect at the start of the tax year, including thresholds, rates and statutory payment figures. Budget staff time for the changeover as well as any annual update cost, because the April transition consumes real hours in every bureau and is routinely left out of the software comparison.
Prices were checked against each vendor's UK pricing on 7 August 2026 and exclude VAT unless stated. Vendors change pricing, so confirm the current figure on the vendor's own site before you buy. Some links are commercial; where we earn a commission it never affects our ratings or the order of this list.
