BreatheHR vs Factorial 2026: Best UK SME HR Software?

Breathe was built by a small UK team with a clear and admirable thesis: that the smallest British businesses deserve real HR software, not just a folder on the shared drive, and that the way to serve them is to keep things simple, friendly, and inexpensive. The product has stayed faithful to that thesis for over a decade. Breathe is approachable, the marketing leans heavily on "Kindness at Work" and culture-led messaging, and the platform is consciously designed to be used by a non-specialist, often the founder, the office manager, or a part-time HR person juggling other responsibilities. Following Breathe's acquisition by ELMO Software in 2020, the product has continued in broadly the same direction, though investment and pace of innovation have arguably slowed.

Factorial was built around a more ambitious thesis: that HR software for SMBs should not have to be thin to be easy to use, and that a modern, well-designed product can deliver the full operational scope of HR (time, payroll, expenses, recruiting, documents, performance, shift planning) without overwhelming the user. The Barcelona team has held that line consistently. Factorial is opinionated in its defaults, fast to set up, and friendly enough that a non-specialist can run it, but it does not stop at the basics. The result is a platform that small businesses can adopt today and still be using when they are five times their current size, without a painful migration to a more capable system.

Breathe is best suited to very small UK businesses, typically in the 10 to 100 employee range, with relatively simple HR needs and operations confined to the United Kingdom. The product is genuinely well-fitted to that profile. For a 25-person London agency that wants to track holiday, store contracts, run a basic appraisal cycle, and stop using a spreadsheet, Breathe does the job competently and at a price that is hard to argue with. Above roughly 100 to 150 employees, however, Breathe starts to feel constrained: the platform's depth, configurability, and cross-country capabilities were not designed for that scale, and customers frequently outgrow it.

Factorial's target band is substantially wider, comfortably serving companies from 20 employees up through several thousand, across more than 60 countries. Critically, Factorial scales down into Breathe's territory without becoming heavy or expensive, and it scales up well past the point where Breathe runs out of room. For a company that is small today but expects to grow, hire across borders, add operational complexity, or simply mature its HR function over the next few years, Factorial is the more durable choice. Choosing Breathe at 30 employees often feels like a good decision; replatforming away from Breathe at 120 employees feels considerably less good, and that migration tax is real.

This is the area where the two products are most clearly playing different games. Breathe covers the essentials of small-business HR: employee records, holiday and sickness tracking, document storage with e-signature, basic performance reviews, simple expense logging, and a recruitment module on higher tiers. The depth in any single area is modest, and several capabilities that mid-sized businesses increasingly take for granted are either thin or absent. Breathe has no native payroll engine. Time tracking is limited and not designed for hourly, shift-based, or project-based workforces. Shift planning is essentially absent. The recruiting module is functional but not competitive with dedicated ATSs or with the recruiting capabilities of more comprehensive HR platforms. Reporting is basic. Integrations are limited.

Factorial covers a substantially broader scope inside a single platform. Native payroll in Spain with deep integrated payroll partnerships across Europe and Latin America. Time tracking that handles salaried, hourly, shift-based, and project-based scenarios out of the box, with break compliance and overtime handling built in. Native expense management with mobile receipt capture, approval workflows, and accounting integrations. Shift planning with availability, swaps, and labour-cost forecasting. A capable recruiting and onboarding module. Performance, goals, and review cycles. Document management with e-signature. People analytics and reporting that go well beyond holiday balances. The breadth gap is not a minor one: it is the difference between a platform that handles the basics and a platform that runs the operational HR function end to end.

Breathe's interface is one of its genuine strengths. The product is simple, friendly, and easy for a non-HR specialist to navigate. Employees figure it out quickly, managers approve requests without training, and admins can find their way around without consulting the help centre. For the audience Breathe was built for, the UX is well-judged.

Factorial competes on the same dimension and, for most users, holds its own comfortably. The interface is modern, clean, and mobile-first, with the same low learning curve that Breathe is known for, and it stays usable as the company grows and the use cases multiply. Where Breathe's simplicity becomes a limitation at scale (there is only so much you can do with a product that was designed to be thin), Factorial's interface continues to support deeper workflows without becoming heavy or cluttered. The mobile experience is meaningfully more capable in Factorial, which matters increasingly as managers approve requests, employees clock in, and HR teams run processes from their phones rather than their desks. Both products are pleasant to use; only one of them stays pleasant as the business scales.

Breathe's pricing is one of its most attractive features and a deliberate part of its positioning. Plans are published transparently, start at a low monthly price, and scale on a per-employee basis. For very small businesses, the base cost is hard to beat. The honest caveat is that the low headline price reflects the narrower scope of the product. To run a complete HR stack on Breathe, most companies end up paying for additional tools (a separate payroll provider, often a separate time-tracking or scheduling tool, sometimes a separate ATS, sometimes a separate expense system), and the all-in cost of running that stack is frequently higher than the Breathe licence alone suggests.

Factorial's pricing is also modular and quote-based, and on a like-for-like comparison of just the HRIS layer it is typically slightly higher than Breathe's headline rate. Once you account for everything Factorial includes natively that Breathe customers have to source elsewhere, the total-cost-of-ownership picture usually flips in Factorial's favour, particularly for companies above 50 employees. For very small businesses with very narrow HR needs, Breathe can still come out cheaper in absolute terms, and that is a fair point in its favour. For most growing SMBs, the all-in spend on a Factorial-centred stack is lower and simpler than the equivalent Breathe-centred stack once you add the missing pieces.

Both platforms are fast to implement compared with traditional HRIS products, and this is a category where Breathe deserves credit. A small business can be live on Breathe in a matter of days, the data model is simple enough that there is not much to configure, and the support team is responsive during onboarding.

Factorial implementations are similarly fast for SMBs of comparable size, typically two to four weeks for a 50 to 300 person company and shorter for smaller teams. The slight additional time reflects the additional surface area being configured (payroll, expenses, time tracking, shift planning) rather than any clunkiness in the platform itself. The relevant comparison is not "Breathe goes live faster" in isolation, but rather "Breathe goes live faster on a smaller scope, and then you spend the next several months implementing the other tools you needed alongside it." On a true end-to-end basis, getting to a complete HR stack is usually faster with Factorial, not slower.

This is the area where the gap between the two products is widest and most consequential for buyers thinking beyond the next twelve months. Breathe has not made AI a meaningful part of its roadmap to date, and the product remains a fairly traditional HR system in its core mechanics. Some incremental improvements have shipped, but there is no serious AI layer at the heart of the platform.

Factorial has invested aggressively in AI as a first-class part of the product. AI is showing up across document understanding, automatic time entry, expense categorisation, recruiting screening, contract drafting, and increasingly in agentic workflows where the platform takes action on behalf of the HR team rather than just surfacing information. The pace of shipping has been visibly fast over the past eighteen months. For a buyer thinking about a five-year horizon, the trajectory difference matters more than today's feature checklist. Picking a platform that is leaning hard into AI, versus one that is not, has compounding consequences for what the HR function will look like in three years' time.

Breathe's integration catalogue is modest, with a handful of connections to UK-focused payroll providers, accounting tools, and a small number of adjacent SaaS systems. The catalogue is appropriate to Breathe's positioning but limits the platform's flexibility in more sophisticated stacks.

Factorial's integration catalogue is broader and growing more quickly, covering Slack, Google Workspace, Microsoft 365, the major ATSs, the major payroll engines across multiple countries, accounting platforms, identity providers, and a long list of SMB tools. More importantly, Factorial customers need fewer integrations in the first place because more of the functionality lives natively inside the product. Fewer external dependencies means fewer points of failure, fewer vendors to manage, and a simpler operational picture.

Breathe is fundamentally a UK product with extensions into Australia and New Zealand following the ELMO acquisition. UK labour law, contract templates, holiday entitlements, and SSP handling are well-supported. Outside that footprint, the product is not really designed to operate. For a UK-only business with no plans to hire abroad, this is fine. For any business that already operates across borders or anticipates doing so, it is a hard ceiling.

Factorial is built for global operation from the ground up and supports more than 60 countries with country-specific labour-law handling, multilingual interfaces, multi-currency, and local payroll capabilities of varying depth depending on the country. Spanish, Portuguese, Italian, French, German, and English are all first-class languages with proper localisation, and UK-specific handling is competitive with Breathe's for the use cases most UK SMBs actually need. For any company that operates internationally, or might in the next few years, Factorial is the only one of these two products that is really designed for the job.

Both vendors have invested in customer support and have generally positive reputations in their respective markets. Breathe has built a notable community through its "Culture Pioneers" programme and other initiatives that encourage small UK businesses to engage with each other on people topics. This is a real and somewhat distinctive strength, and worth acknowledging: Breathe has done something more ambitious than just running webinars.

Factorial's support is fast, multilingual, and consistently rated well across plan tiers. The community side is less folksy than Breathe's but the practical day-to-day support experience (getting an actual answer to an actual problem in a reasonable timeframe) is strong. For a buyer choosing primarily on community feel, Breathe has a distinctive offering. For a buyer choosing primarily on operational support quality, the two are comparable.

It is worth being clear about the scenario where Breathe is the right answer. If you are a UK-based small business in the 10 to 80 employee range, with operations confined to the UK, with no near-term plans to expand internationally, with relatively simple HR needs (holidays, sickness, contracts, basic appraisals), with a tight budget, and with a strong cultural affinity for Breathe's "Kindness at Work" philosophy and community, Breathe is a perfectly reasonable choice. The product does what it sets out to do, it does it inexpensively, and the team behind it is sincere about its mission. Recommending against Breathe in that scenario would be unfair.

For most other SMBs, including many that look on paper like they might be Breathe candidates, Factorial is the stronger choice. It is broader in native functionality, more capable as you grow, more global in its localisation, more ambitious in its AI roadmap, and more durable as a long-term platform decision. It scales down to small companies that Breathe serves well, and it scales up well past the point where Breathe runs out of room. For any business that operates outside the UK, has hourly or shift-based workers, wants payroll inside the platform, expects meaningful growth, or simply wants HR software that will still be a fit in five years, Factorial is the more confident recommendation.

The choice between Factorial and Breathe HR is really a choice about timing and ambition. Breathe is a thoughtful, friendly, narrowly-scoped product built for a specific kind of small UK business, and it serves that audience honestly. Factorial is a broader, deeper, more globally-capable platform built for SMBs that want their HR software to grow with them rather than being replaced once the business outgrows its first system. For very small UK companies with simple needs and no growth ambitions, Breathe is fine. For most other companies, and certainly for any company that operates internationally, has operational HR complexity, or expects to be meaningfully larger in three years than they are today, Factorial is the better long-term decision. Choosing the platform that fits where the business is going, rather than only where it is today, is almost always the wiser call.
