Making Tax Digital for Income Tax starts in April 2026 for sole traders and landlords earning over £50,000. That deadline alone has pushed accounting software from “nice to have” to “legally required” for thousands of UK businesses.
But the accounting software market is confusing. Xero, QuickBooks, and Sage all claim to be the best option for UK small businesses, and they all charge different amounts for features that sound identical until you read the fine print.
We compared the three platforms that dominate UK small business accounting. Not the enterprise versions, not the ones aimed at accountancy practices. The ones a sole trader, partnership, or limited company with under 20 employees would actually use day to day.
Before You Pick a Platform
If you are a sole trader with fewer than 20 invoices a month and no employees, you do not need a £50/month plan. Start with the cheapest tier of any platform and upgrade when you outgrow it. The features that matter at the start are bank reconciliation, invoice creation, and VAT returns. Everything else is noise until your business is complex enough to need it.
If you already have an accountant, ask them what they prefer. Most UK accountants are either Xero or QuickBooks partners, and using the same platform as your accountant saves time and money on both sides. Do not pick a tool and then ask your accountant to adapt to it.
1. Xero
From £16/month (excl. VAT) | 30-day free trialXero is the platform most UK accountants recommend, and for good reason. It has the largest accountant partner network in the UK, the cleanest bank reconciliation workflow, and a marketplace of over 1,000 integrations. If your accountant uses Xero, this decision is already made.
The entry plan (Ignite, formerly Starter) costs £16/month and gives you 20 invoices, 5 bills, and bank reconciliation. For most sole traders and micro businesses, that is enough. The Grow plan at £37/month removes the invoice cap, adds payroll for one employee, and includes multi-currency support. The Comprehensive plan at £50/month adds payroll for five employees and project tracking.
What is good
Bank reconciliation is best in class. Connect your UK bank account and Xero pulls transactions automatically, matching them against invoices and bills. The matching suggestions improve over time and genuinely save hours each month. Unlimited users on all plans except Ignite. Your accountant, bookkeeper, and business partner can all access the system without paying per seat. The app marketplace is the largest of the three platforms. Stripe, GoCardless, Shopify, PayPal, Receipt Bank, and hundreds more connect natively. MTD compatible across all plans, with direct HMRC submission for VAT returns. ISO 27001 certified with data stored on AWS infrastructure.
Watch out for
The Ignite plan caps invoices at 20 per month. If you invoice more than that, you are immediately pushed to the £37/month Grow plan. There is no middle ground. Payroll is not included on the entry plan. You need Grow (£37/month) for one employee, or Comprehensive (£50/month) for five. Beyond five, you pay £1.50 per additional employee per month. Xero does not include a built-in payment gateway. You need to connect Stripe or GoCardless separately, which adds transaction fees on top of your subscription.
MTD compliance
Xero is HMRC-recognised for Making Tax Digital for VAT and is preparing for MTD for Income Tax (ITSA). All plans support direct VAT submission to HMRC. The platform also handles CIS (Construction Industry Scheme) returns, which matters if you work in trades or construction.
Best for: UK small businesses that work with an accountant, need clean bank reconciliation, and want a platform they will not outgrow quickly. The default choice for a reason.
2. QuickBooks
From £10/month (after promo) | Sole Trader plan availableQuickBooks is Xero’s closest competitor in the UK and the stronger option for businesses that manage their own books without an accountant. The interface is more guided than Xero, walking you through tasks step by step rather than assuming you know what double-entry bookkeeping means.
The Sole Trader plan costs £10/month (after a promotional first six months at £1/month). Simple Start is £16/month, Essentials is £28/month, and Plus is £50/month. The recent price increases in January 2026 pushed costs up significantly, with prices rising roughly 75% since 2022.
What is good
The Sole Trader plan is purpose-built for self-employed UK workers. It handles Self Assessment, mileage tracking, and simplified expenses in a way that Xero does not match at the entry level. The onboarding experience is the best of the three platforms. QuickBooks walks new users through setup with a checklist, video tutorials, and in-app guidance. If you have never used accounting software before, this matters. Receipt capture via the mobile app is excellent. Photograph a receipt, QuickBooks extracts the data, categorises the expense, and matches it to a bank transaction. MTD for VAT is built in across all paid plans.
Watch out for
The January 2026 price increase hit existing customers hard. The Plus plan jumped from £34 to around £50/month. If you are comparing against Xero at the same price point, QuickBooks now needs to justify itself on features rather than cost. The accountant network is smaller than Xero in the UK. Many UK accountancy practices are Xero-first, so check with your accountant before committing. The Advanced plan at £123/month includes AI features (Finance Agent, Project Management Agent), but these are overkill for most small businesses and add cost without clear value at this stage.
MTD compliance
QuickBooks is HMRC-recognised for MTD for VAT. The platform also supports MTD for Income Tax (ITSA) readiness for the April 2026 deadline. Self Assessment features on the Sole Trader plan make it particularly strong for sole traders approaching the new requirements.
Best for: Sole traders and self-employed people managing their own books. Also strong for small businesses that do not use an external accountant and want guided, step-by-step workflows. The Sole Trader plan has no real equivalent on Xero or Sage.
3. Sage Accounting
From £15/month (excl. VAT) | Free 3-month trial often availableSage is the legacy name in UK accounting software. The company has been around for over 40 years and has deeper roots in UK business than either Xero or QuickBooks. Sage Accounting (the cloud version) is the modern successor to Sage 50, which many UK businesses still run on desktop.
The Start plan costs £15/month for basic invoicing, expense tracking, and bank reconciliation. Standard at £30/month adds VAT compliance and multi-user access. Plus at £59/month includes inventory management, budgeting, and multi-currency support.
What is good
Sage has the deepest integration with HMRC of the three platforms. VAT returns, CIS submissions, and payroll reporting are built around UK tax requirements specifically, not adapted from a US or Australian product. The payroll add-on (Sage Payroll) is genuinely best in class for UK businesses. It handles PAYE, pension auto-enrolment, and RTI submissions natively. If you run payroll for even a small team, Sage handles it more smoothly than Xero or QuickBooks. Customer support is UK-based with phone support available. This matters when you are stuck on a VAT return at 11pm on the filing deadline.
Watch out for
The app marketplace is significantly smaller than Xero. If you rely on third-party integrations for your workflow (e-commerce platforms, CRM systems, payment processors), check that Sage supports them before committing. The interface feels dated compared to Xero and QuickBooks. It is functional, but the design has not kept pace with competitors. If you are coming from a modern tool, it can feel clunky. Bank feeds are less reliable than Xero. Some UK banks have patchy connections with Sage, and the automatic matching is not as intelligent. You may spend more time manually reconciling transactions.
MTD compliance
Sage is HMRC-recognised for MTD for VAT and is preparing for MTD for Income Tax. As a UK-founded company, Sage has historically been first to implement HMRC requirement changes. The payroll integration with HMRC for RTI (Real Time Information) is seamless.
Best for: UK businesses that run payroll in-house, need deep HMRC integration, and prefer UK-based phone support. Also the natural upgrade path for any business currently on Sage 50 desktop software.
Quick Comparison
| Feature | Xero | QuickBooks | Sage |
|---|---|---|---|
| Entry price | £16/month | £10/month | £15/month |
| Mid-tier price | £37/month | £28/month | £30/month |
| Invoice limit (entry plan) | 20/month | Unlimited | Unlimited |
| Payroll included | From £37/month (1 employee) | Add-on required | Separate product (best in class) |
| Bank reconciliation | Excellent | Good | Adequate |
| UK accountant network | Largest | Growing | Strong (legacy) |
| Sole trader plan | No | Yes (£10/month) | No |
| App marketplace | 1,000+ integrations | 750+ integrations | Limited |
| MTD for VAT | Yes | Yes | Yes |
| MTD for Income Tax | Preparing | Preparing | Preparing |
| UK phone support | No (chat/email) | Limited | Yes |
| Free trial | 30 days | 30 days | Often 3 months free |
The Bottom Line
For most UK small businesses, Xero is the strongest choice. The accountant network is the largest, bank reconciliation is the best, and the integration marketplace means it connects to practically everything else you use. If your accountant already uses Xero, this is not even a decision.
If you are a sole trader managing your own books, QuickBooks is worth a serious look. The Sole Trader plan at £10/month is purpose-built for self-employed people and handles Self Assessment, mileage, and simplified expenses better than either competitor at that price.
Sage is the right pick for businesses that run payroll in-house and want UK-based phone support. The payroll product is genuinely the best of the three, and the HMRC integration runs deeper than the others. If you are migrating from Sage 50 desktop, staying in the Sage ecosystem makes the transition smoother.
All three platforms handle MTD for VAT. All three are preparing for MTD for Income Tax. The platform you pick matters less than whether you actually use it consistently. Pick one, set up bank feeds, and reconcile weekly. That habit alone will save you more than any feature comparison.
