Best Accounting Software for Sole Traders in the UK

As a sole trader in the UK, keeping your finances in order is not optional — it is a legal requirement. With Making Tax Digital (MTD) now firmly in place for VAT-registered businesses and Self Assessment digitalisation on the horizon, choosing the right accounting software has never been more important.

Whether you are a freelancer, a tradesperson, or a one-person shop, this guide covers the best options available right now, with UK pricing and features that actually matter to small business owners.

What Sole Traders Should Look for in Accounting Software

The right software should handle your day-to-day bookkeeping without requiring an accountancy degree. Look for MTD compliance, UK bank feed integrations, invoicing tools, and straightforward Self Assessment support.

Equally important is pricing. As a sole trader, you likely do not need a full enterprise suite — a clean, affordable platform that handles invoicing, expenses, and HMRC submissions will serve most people well.

Our Top Picks for Sole Traders

Xero — Best Overall for Growing Sole Traders

Xero starts at £15 per month and is one of the most widely used accounting platforms in the UK. It is fully compliant with Making Tax Digital and offers strong integrations with major UK banks, making it straightforward to reconcile transactions automatically.

The platform offers a 30-day free trial with no credit card required, which is ideal if you want to test it properly before committing. Xero also connects with a wide ecosystem of UK-friendly apps, including Zettle and SumUp for payment processing.

FreeAgent — Best for Freelancers and Self-Employed Professionals

FreeAgent at £19 per month is built with sole traders and freelancers firmly in mind. It includes HMRC submission tools built directly into the platform, covering both VAT returns and Self Assessment — a genuine time-saver come January.

Like Xero, FreeAgent offers real-time UK bank feed integrations and a free trial without needing a credit card. It is also worth noting that NatWest and Royal Bank of Scotland business account holders may be eligible for FreeAgent at no extra cost — worth checking if you bank with either.

Sage Accounting — Best for Tradespeople and VAT-Registered Sole Traders

Sage is particularly well-suited to sole traders in trades such as plumbing or catering, where invoicing, expenses, and VAT all need to work together seamlessly. Its long-standing reputation in the UK market means your accountant is very likely already familiar with it.

Square — Best Free Option for Sole Traders Just Starting Out

Square offers a genuinely free tier with no monthly fee, making it an attractive starting point for sole traders who are not yet ready to commit to a paid subscription. It covers payments, invoicing, and basic scheduling in one place, accessible via iOS, Android, and web.

While Square is primarily a point-of-sale and payments platform rather than a dedicated accounting tool, it can work well alongside a lightweight bookkeeping solution for very early-stage businesses. It integrates with Xero, which makes upgrading straightforward as your business grows.

Which Software Is Right for You?

If you are VAT-registered or approaching the threshold, Xero or Sage Accounting offer the most robust MTD compliance and bank integrations at a similar price point. If you are a freelancer who dreads Self Assessment, FreeAgent is arguably the most purpose-built option for your situation.

For sole traders just launching their business, Square's free tier provides a low-risk way to handle invoicing and payments immediately, without any upfront cost.

Final Thoughts

The best accounting software for sole traders is the one you will actually use consistently. All three paid options — Xero, FreeAgent, and Sage — offer free trials, so there is nothing to stop you testing each before making a decision.

With GDPR obligations and HMRC's digitalisation agenda both requiring accurate, secure record-keeping, investing in the right software now will save you significant stress and potential penalties further down the line.
