Choosing accounting software is one of the few software decisions a UK small business genuinely cannot get wrong, because the wrong choice costs you at the VAT deadline, at year end and every time you try to work out whether you can afford to hire. The good news is that the UK market is mature and competitive, and there is a genuinely strong option at almost every price point.
We have put the leading tools head to head on the things that matter to a British business: real pricing excluding VAT, how cleanly they handle Making Tax Digital for VAT, whether payroll is included or extra, and how much bookkeeping you can actually get done without an accountant on speed dial. Here is how they rank for 2026.
What to look for in UK accounting software
Start with Making Tax Digital. Any accounting software you choose should be recognised by HMRC for MTD for VAT, and increasingly for Income Tax too, so that you can keep digital records and file returns directly rather than through a workaround. This is now a baseline requirement rather than a nice to have, and every option we recommend clears it.
Beyond compliance, weigh four things. First, the real cost, which means the renewal price excluding VAT rather than a first year discount, and whether payroll is included or charged separately, because that single factor can flip which product is cheapest. Second, bank connectivity and reconciliation, since this is where you will spend most of your time and a good feed saves hours every month. Third, whether it handles any sector specifics you need, such as CIS for construction or multi currency for importers. And fourth, whether your accountant already knows it, because collaboration is far smoother when you both work in the same system.
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 remains the one to beat for most UK small businesses. The bank reconciliation is the fastest in the category, payroll is included from the Grow plan upwards, and the app marketplace connects to almost anything else you run. It is the tool an accountant is most likely to already know, which makes support and collaboration easy.
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 most businesses should start on Grow.

2. QuickBooks Online
QuickBooks Online matches Xero feature for feature and pulls ahead on automated bank categorisation, which quietly saves hours every month. CIS is handled from the entry tier and project profitability on the Plus plan is genuinely useful for anyone billing by job.
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 headline discounts hide a renewal price that is much higher, so budget on the standard rate.

3. Sage Accounting
Sage Accounting has become a stronger proposition since it started bundling payroll and an AI assistant into every plan. For a small firm that pays a handful of staff, that removes an entire second subscription, and once you add payroll into the comparison Sage often works out cheaper than it first looks.
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, so realistically you are on Standard.

4. FreeAgent
FreeAgent is purpose built for the single director limited company, and its trump card is price: it is free for as long as you bank with NatWest, Royal Bank of Scotland, Ulster or Mettle. The tax timeline showing what is owed and when is worth the switch on its own for a contractor.
What you get: A UK accounting product owned by NatWest, aimed squarely at limited company contractors and sole traders. Free for as long as you bank with the group. It holds a 4.0 out of 5 rating across 497 reviews on Assaylist.
Pricing: The plans run Free with NatWest, RBS, Ulster or Mettle at free, Sole trader at £19 and Limited company at £33 per month, excluding VAT.
Why we rate it:
- Free with a NatWest, RBS, Ulster or Mettle account
- Built for UK limited company contractors
- Tax timeline showing what is owed and when
- Corporation Tax and dividend handling
Bear in mind: it does not scale to stock or larger teams, so you will move on if you grow.

5. Zoho Books
Zoho Books gives you more capability per pound than anything else here, including a free plan that files Self Assessment and Corporation Tax filing from the Standard tier. If you already use other Zoho apps the integration is seamless, and even standalone it is remarkable value.
What you get: Part of the wider Zoho suite. The UK edition files SA100 and CT600, handles MTD and CIS, and starts at nothing for one user. It holds a 4.0 out of 5 rating across 325 reviews on Assaylist.
Pricing: The plans run Free at free, Standard at £12 and Professional at £24 per month, excluding VAT.
Why we rate it:
- Free plan that files Self Assessment
- Corporation Tax filing from Standard
- Property tracking for landlords
- Native Zoho suite integration
Bear in mind: fewer UK accountants know it, so check yours will work with it first.

6. QuickFile
QuickFile is the quiet outlier: genuinely free below a thousand ledger entries a year and only sixty pounds a year above that, with unlimited users on every plan. For a micro business or a landlord it is very hard to beat on cost, and it is a UK company holding UK data.
What you get: A UK company offering full accounting software free for smaller businesses, with a flat £60 a year charge only once your transaction volume grows. It holds a 4.1 out of 5 rating across 203 reviews on Assaylist.
Pricing: The plans run XS, S and M at free, L and XL at £60 and Automated bank feeds at £15 per year, excluding VAT.
Why we rate it:
- Genuinely free below 1,000 ledger entries
- Unlimited users on every plan
- £60 a year at the paid tier, not per month
- UK company holding UK data
Bear in mind: the interface is dated and bank feeds are a small paid extra.

How much should you budget?
Cloud accounting for a UK small business typically costs between fourteen and sixty pounds a month excluding VAT, depending on the tier and whether payroll is included. Entry plans around fourteen to twenty pounds suit a sole trader or a simple limited company, mid tiers around forty pounds add multi user access, quotes, forecasting and CIS, and top tiers near sixty pounds bring inventory and multi currency. Free options exist for the smallest businesses, notably QuickFile and the free tiers of Zoho Books and Sage Sole Trader.
The figure to watch is the renewal price rather than the introductory discount, since several vendors advertise heavy first year savings and then step up sharply. Factor payroll into the comparison too, because a product that bundles it can undercut one that charges separately once you add a payroll subscription. Budget on the total you will actually pay in year two, not the headline you see at sign up.
Our verdict
For most UK small businesses, Xero is still the safest excellent choice, with QuickBooks Online the equal for anyone who values automation and does not mind watching the renewal price. If you pay staff, price Sage Accounting with payroll included before you decide, because the bundle changes the maths.
Contractors banking with the right group should look hard at FreeAgent for the free tier, and the genuinely cost conscious will find QuickFile and Zoho Books deliver far more than their price suggests. There is no single winner for every business, only the right fit for yours, and the good news is that every option on this list is one you could run happily for years.
The bottom line
If you want a single recommendation, choose Xero and you will be well served, or QuickBooks Online if automation matters more to you than the renewal price. But the honest answer is that the best accounting software is the one that matches your specific situation: your size, whether you pay staff, your sector and which tool your accountant prefers. Use the free trials, because an evening spent testing two shortlisted options against your own figures tells you more than any review, including this one. Whatever you choose from this list, you are choosing a tool you could run happily for years.
Frequently asked questions
Which accounting software is best for UK small businesses?
Xero is the best overall choice for most UK small businesses in 2026 thanks to its fast bank reconciliation, bundled payroll from the Grow plan and huge app marketplace. QuickBooks Online is an equally strong alternative, and Sage Accounting is often better value once you factor in its included payroll.
Is Xero or QuickBooks better in the UK?
They are very close. Xero has the edge 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.
What is the cheapest accounting software in the UK?
QuickFile is free below a thousand ledger entries a year and sixty pounds a year above that. Zoho Books and Sage Sole Trader both have free tiers, and FreeAgent is free for customers of NatWest, RBS, Ulster or Mettle. For a paid cloud package, entry plans start around fourteen to twenty pounds a month excluding VAT.
Does small business accounting software handle Making Tax Digital?
Yes. Every product on this list is recognised by HMRC for Making Tax Digital for VAT, and most are ready for MTD for Income Tax as well. Filing your VAT return directly from the software is standard, and it is one of the main reasons to move off spreadsheets.
Do I need accounting software if I have an accountant?
In practice, yes. Making Tax Digital requires digital record keeping, and giving your accountant access to live software is far cheaper and less error prone than sending spreadsheets. Most accountants will actively prefer you to be on Xero, QuickBooks or Sage so they can work in the same system.
Prices were checked against each vendor's UK pricing on 6 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.
