Frequently Asked Questions
What is the best accounting software for sole traders in the UK?
FreeAgent is our top pick for sole traders, especially if you have a NatWest or RBS business account (it is free). It is designed specifically for UK freelancers and handles Self Assessment seamlessly.
Is Xero better than QuickBooks?
Both are excellent. Xero has more integrations (1000+) and is preferred by most UK accountants. QuickBooks is slightly cheaper and has better built-in tax tools. Choose Xero if integrations matter, QuickBooks if budget is the priority.
Can I use free accounting software in the UK?
Yes. Wave is completely free for accounting and invoicing. However, it lacks MTD compliance and has limited UK bank feeds, so it is best for very small businesses or freelancers with simple needs.
Do I need MTD-compatible software?
If your business is VAT-registered or earns over the income tax threshold, you must use MTD-compatible software to submit returns to HMRC. All of our top picks except Wave are MTD compatible.
