Xero vs QuickBooks vs FreeAgent: Which Is Best for a Small UK Business?

For a UK sole trader or small limited company, FreeAgent is the cheapest option (free with Starling Business or Mettle accounts), Xero is the best all-rounder for small businesses with growing complexity, and QuickBooks is the most flexible if you want strong reporting and integrations. For most freelancers and businesses with under £100k turnover, FreeAgent is the right starting point. For limited companies wanting to scale, Xero usually wins.

Xero vs QuickBooks vs FreeAgent at a glance

What does each one actually cost in the UK?

Prices below are correct as of early 2026 — always check the providers' websites for current rates.

FreeAgent

• Free with a Starling Business or Mettle bank account (this is the genuine differentiator)
• Otherwise: £19/month for sole traders, £29/month for partnerships, £33/month for limited companies
• 50% off the first 6 months for new customers

Xero

• Starter (£16/month): basic invoicing, bank feeds, limited transactions
• Standard (£33/month): unlimited transactions, payroll add-on
• Premium (£47/month): multi-currency, more features
• Most small businesses end up on Standard

QuickBooks (UK)

• Self-Employed (~£10/month): for sole traders, includes Self Assessment
• Simple Start (~£15/month): for small ltds with basic needs
• Essentials (~£25/month): adds bills and multi-currency
• Plus (~£35/month): adds project tracking, inventory
• Most small businesses end up on Essentials or Plus

The real cost difference: FreeAgent at £0/month (with the right bank account) vs Xero at ~£33/month vs QuickBooks at ~£25/month. Over a year, that is about £300–£400 saved.

Which one is easiest to use for a non-accountant?

FreeAgent is the most beginner-friendly. The interface is built for non-accountants, the setup wizard walks you through everything, and the dashboard shows you exactly what tax you owe and when. If you have never used accounting software, this is the gentlest learning curve.

Xero is also easy but assumes slightly more familiarity with accounting concepts. The interface is cleaner than QuickBooks, and most accountants in the UK now know Xero well so you can hand it off easily.

QuickBooks has the most features, which means it has the steepest learning curve. It is perfectly usable, but expect to spend longer on initial setup and to occasionally hunt for things that other platforms put on the front page.

Which one fits which business?

Choose FreeAgent if:

• You are a sole trader, contractor, freelancer, or small limited company
• Your turnover is under £100k (it works fine above that, but the value really shines below)
• You bank with Starling Business or Mettle (free!)
• You want to file Self Assessment directly from your accounting software
• You want a UK-built tool with UK-focused support
• You are not yet VAT-registered or have simple VAT needs

Choose Xero if:

• You are a small limited company with growing complexity
• You expect to scale and want software that scales with you
• You work with an accountant (most UK accountants prefer Xero)
• You need multi-currency invoicing (UK + EU + USD clients)
• You want the largest app marketplace (1,000+ integrations)
• You manage payroll for staff

Choose QuickBooks if:

• You need strong project costing and time tracking
• You want detailed reporting and analytics
• You have inventory to track
• You like having more features available (even if you do not use them all)
• Your accountant specifically uses QuickBooks
• You manage complex VAT situations across regions

What about the "free with bank account" angle?

This is the killer feature for FreeAgent. If you bank with Starling Business or Mettle (NatWest's free business account), FreeAgent is genuinely free for as long as you keep that account open. That saves £200–£400 a year compared to Xero or QuickBooks.

For most small businesses starting out, this makes FreeAgent the obvious starting point — even if you eventually outgrow it.

There is no equivalent free option for Xero or QuickBooks. Some banks (Mettle excluded) bundle accounting promotional discounts, but nothing matches FreeAgent's "actually free, indefinitely" model.

What does SME Shack actually use?

We use FreeAgent. The combination of free-with-Starling pricing, UK focus, and direct Self Assessment integration makes it the right call for a small UK limited company. We have used Xero on previous projects and rate it highly — we just do not need its extra features yet.

If you are setting up a small UK business and trying to decide between these three, our practical advice is:

1. Open a Starling Business or Mettle account (both free)
2. Activate the free FreeAgent inside your bank account dashboard
3. Stay on it until you genuinely need something else

Most small businesses never outgrow FreeAgent. The ones that do usually move to Xero.

Frequently asked questions

Q: Can I switch from one to another later?

A: Yes, but it is some work. All three platforms support exporting and importing data via CSV, and there are migration services that automate the move. Budget a half-day or so for a small business migration. Do it at the start of a financial year if possible — it makes the bookkeeping cleaner.

Q: What does my accountant prefer?

A: Most UK accountants prefer Xero, with FreeAgent in a strong second place. QuickBooks is well-supported but slightly less common. Always ask your accountant before choosing — they will work much faster if you use software they know.

Q: Are any of these compatible with Making Tax Digital (MTD)?

A: All three are HMRC-recognised for Making Tax Digital, including for VAT and the upcoming MTD for Income Tax (currently rolling out). You will not have to switch software because of MTD.

Q: Can I do my own books on these without an accountant?

A: Yes, especially with FreeAgent. The platform is built for non-accountants and many sole traders use it without ever hiring one. For limited companies, we still recommend at least an annual review by an accountant — they often save you their fee in tax planning alone. Many UK accountants offer a "review only" service for £200–£500 a year if you do the books yourself.

Q: What about Wave, Sage, or other alternatives?

A: Wave is free and serviceable, but it is US-focused and does not handle UK VAT or Making Tax Digital well. Sage is the legacy market leader but feels dated next to Xero and FreeAgent. For a small UK business in 2026, FreeAgent, Xero, and QuickBooks are the three to compare.
