Frequently Asked Questions
Do sole traders need accounting software?
You are not legally required to use software, but it makes record-keeping dramatically easier. HMRC requires digital records under Making Tax Digital, and software automates calculations, reduces errors, and saves hours at tax time.
What is the cheapest accounting software for sole traders?
Wave is free. FreeAgent is free if you have a NatWest or RBS business account. QuickBooks starts at £12/month and is the cheapest paid option with full UK tax support.
Can I do my own Self Assessment with accounting software?
Yes. FreeAgent, QuickBooks, and Xero all guide you through Self Assessment and can submit directly to HMRC. This can save you hundreds of pounds in accountant fees.
