Xero, QuickBooks and Sage are the three names that dominate UK accounting software, and for most businesses the real decision comes down to these three rather than the wider market. They are all mature, all recognised by HMRC for Making Tax Digital, and all capable of running a small business well. The differences are in the detail, and the detail is what should decide your choice.
We have put the three head to head on the things that actually separate them: real pricing excluding VAT, how payroll is handled, ease of use, and the strength of the ecosystem around each. Here is how they compare, and a clear verdict on which one you should choose.
How to choose between them
When two or three products are this close, the decision rarely comes down to a feature one has and the others lack, because at this level they all cover the essentials. Instead it comes down to fit. Compare them on the total cost including payroll rather than the headline accounting price, because bundling changes the ranking. Consider which interface you personally find easier, since you will use it daily. And ask your accountant whether they have a preference, because working in the same system makes collaboration far smoother.
It is also worth thinking about where you will be in two years, not just today. The cost of switching accounting software later, while manageable, is real, so a tool you can grow into is worth a small premium over one you might outgrow. The reassuring truth is that among the leading options, there is no bad choice, only the one that fits your business best.
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. Xero
Xero wins on the things you touch every day. Its bank reconciliation is the fastest of the three, it allows unlimited users on every plan where the others charge by seat, and its app marketplace is the largest. Payroll is included from the Grow plan, and it is the tool an accountant is most likely to already know well.
What you get: The New Zealand built platform that reshaped UK cloud accounting. Four tiers, bundled payroll from the Grow plan upwards, and a very large app ecosystem. It holds a 4.1 out of 5 rating across 293 reviews on Assaylist.
Pricing: The plans run Ignite at £16, Grow at £37, Comprehensive at £50 and Ultimate at £65 per month, excluding VAT.
Why we rate it:
- Fastest bank reconciliation in the category
- Unlimited users on every tier
- Payroll included from the Grow plan
- Huge app marketplace and strong API
Bear in mind: the entry Ignite plan is very tight, so budget for Grow.

2. QuickBooks Online
QuickBooks Online matches Xero on core features and pulls ahead on automated bank categorisation, which saves real time each month. It includes CIS from the entry tier, which matters for construction, and its project profitability on the Plus plan is genuinely useful. The catch is a renewal price well above the headline offer.
What you get: Intuit's cloud accounting software, sold in four tiers from Simple Start to Advanced. Strong automation, deep app ecosystem, aggressive introductory discounting. It holds a 4.1 out of 5 rating across 235 reviews on Assaylist.
Pricing: The plans run Simple Start at £14.33, Essentials at £34.2, Plus at £50.4 and Advanced at £110.7 per month, excluding VAT.
Why we rate it:
- Strong automated bank categorisation
- CIS from the entry tier
- Project profitability tracking
- Very large app marketplace
Bear in mind: the introductory discount hides a much higher renewal price.

3. Sage Accounting
Sage Accounting's trump card is bundled payroll on every plan, which can make it the cheapest of the three once you factor payroll in, since Xero and QuickBooks charge for it separately or by allowance. Backed by decades of UK payroll experience, it is the strongest choice for a business that pays staff and wants one supplier.
What you get: Sage's main cloud accounting product for small UK businesses. Payroll for one employee and the Sage Copilot assistant are now bundled into all three tiers. It holds a 4.0 out of 5 rating across 394 reviews on Assaylist.
Pricing: The plans run Start at £20, Standard at £43 and Plus at £59 per month, excluding VAT.
Why we rate it:
- Payroll included in every plan
- Making Tax Digital for VAT
- Sage Copilot AI assistant
- CIS management and submission
Bear in mind: the Start tier is too limited for most, so plan on Standard.

What about the other options?
Xero, QuickBooks and Sage dominate the conversation, but they are not the only credible choices for a UK business, and it is worth knowing where the alternatives fit. FreeAgent is purpose built for the single director limited company and is free for customers of NatWest, Royal Bank of Scotland, Ulster and Mettle, which makes it a strong contender for contractors specifically, even against these three giants.
For the cost conscious, Zoho Books delivers remarkable value, including a free plan that files Self Assessment and Corporation Tax filing from its Standard tier, and QuickFile is genuinely free for the smallest businesses below a thousand ledger entries a year. These are not compromises so much as better fits for particular situations. The big three are the safe default for most businesses, but if you are a contractor, a micro business or simply value conscious, one of these alternatives may serve you better, so do not rule them out just because they are less famous.
One practical reason the big three dominate, though, is worth understanding: accountant familiarity. Ask almost any UK accountant about Xero, QuickBooks or Sage and you will get an informed answer and confident support, because they use these products every day across their client base. The alternatives are excellent software, but if you want your accountant working inside your books, it is worth checking they are comfortable with your chosen tool before you commit. For many businesses, the smoothness of that collaboration is worth as much as any individual feature, which is exactly why Xero, QuickBooks and Sage remain the default recommendation even in a market with strong challengers.
How much should you budget?
On accounting alone, the leading products sit within a similar range, with entry plans of roughly sixteen to twenty pounds a month excluding VAT and top small business tiers near sixty. The number that actually separates them is payroll. Sage bundles it into every plan, while Xero includes an allowance from a certain tier and QuickBooks charges for it as an add on, so the cheapest option depends entirely on whether and how you pay staff.
Work out your total monthly cost with payroll included at your real headcount, and compare that figure rather than the advertised accounting price. Once you do, the ranking on cost often looks quite different from the one you would guess from the headline plans.
Our verdict
For most UK businesses, Xero is the best all round choice, winning on daily ease of use, unlimited users and the app ecosystem. QuickBooks Online is its equal for anyone who prioritises automation and does not mind watching the renewal price, and it has the edge for construction businesses needing CIS from the entry tier.
Sage Accounting is the value winner the moment payroll enters the comparison, because bundling it can undercut the others once you add their payroll costs. The honest answer is that all three are excellent, so compare them on total cost including payroll, on whether your accountant has a preference, and on which interface you find easier. You will not make a bad choice among these three.
The bottom line
All three are excellent, so you will not make a bad choice. Xero wins on daily ease of use and ecosystem, QuickBooks on automation, and Sage on bundled payroll and total cost once staff are involved. Compare them on the full monthly cost including payroll at your real headcount, ask your accountant if they have a preference, and pick the interface you find easier, because you will be using it every day for years. Above all, take each one for a genuine test drive before you commit, because half an hour spent entering a few real invoices into each will tell you more about which one suits the way you think than any comparison table ever could.
Frequently asked questions
Is Xero or QuickBooks better in the UK?
They are very close. Xero leads on bank reconciliation, unlimited users and the app marketplace, while QuickBooks Online leads on automated categorisation and includes CIS from the entry tier. Compare them on the renewal price rather than the introductory discount, and on whether you need payroll included.
Is Sage better than Xero and QuickBooks?
Sage's main advantage is bundled payroll on every plan, which can make it cheaper once payroll is factored in, plus decades of UK compliance experience. Xero and QuickBooks lead on ease of use and automation respectively. For a business that pays staff, Sage is very competitive on total cost.
Which is cheapest, Xero, QuickBooks or Sage?
On accounting alone, all three have entry plans in a similar range of roughly sixteen to twenty pounds a month excluding VAT. Once you add payroll, Sage often becomes cheapest because it bundles payroll, whereas Xero and QuickBooks charge for it separately. Always compare on the total including payroll.
Do all three handle Making Tax Digital?
Yes. Xero, QuickBooks and Sage are all recognised by HMRC for Making Tax Digital for VAT and are ready for MTD for Income Tax. Filing your VAT return directly from the software is standard in all three, so compliance is not a deciding factor between them.
Can I switch between Xero, QuickBooks and Sage?
Yes, though switching is easiest at the start of a financial year and usually involves some data migration. All three support importing data, and accountants routinely move clients between them. If you are unsure, ask your accountant which they prefer to work in, as that can make collaboration smoother.
