Cheapest Accounting Software for Sole Traders UK 2026

Introduction

When you are a sole trader, every expense needs to justify itself. Accounting software is no different. You need something that keeps HMRC satisfied and your finances organised, but you do not want to overpay for features you will never use.

This guide lists the cheapest accounting software options for UK sole traders in 2026, from free to affordable, with an honest assessment of what you get and what you sacrifice at each price point.

The Free Options

FreeAgent (via NatWest)

Price: free with a NatWest, RBS, or Ulster Bank business account.

What you get: full-featured accounting platform including bank feeds, invoicing, Self Assessment, MTD filing, expense tracking, and financial reports.

The trade-off: you must bank with NatWest Group. If you switch banks, the price jumps to around £19 per month.

Verdict: if you bank with NatWest, this is unbeatable. It is a genuinely comprehensive platform at no cost.

Wave

Price: free.

What you get: invoicing, expense tracking, receipt scanning, bank connections, basic reporting.

The trade-off: Wave is North American. UK tax handling is poor, there is no MTD compliance, and VAT support is basic.

Verdict: usable for very basic record-keeping but lacks essential UK-specific features.

Pandle (Free Tier)

Price: free.

What you get: basic bookkeeping, invoicing, bank feeds.

The trade-off: no MTD filing on the free tier. You need the paid plan (from around £5 per month) for that.

Verdict: a decent starting point if you are testing whether a platform works for you.

Spreadsheets

Price: free (Google Sheets) or included with Office 365.

What you get: complete flexibility, familiar interface.

The trade-off: no automation, no bank feeds, no receipt scanning, no tax calculations, error-prone, time-consuming.

Verdict: technically viable for HMRC compliance when combined with free bridging software, but practically unsustainable for most businesses.

The Budget Options (Under £10/Month)

Pandle Paid Plans

Price: approximately £5-£9 per month.

What you get: everything in the free tier plus MTD filing, additional reports, and premium support.

The trade-off: fewer features and integrations than larger competitors.

Verdict: good value for simple sole trader bookkeeping with MTD compliance.

QuickBooks Self-Employed

Price: approximately £8 per month.

What you get: expense tracking, receipt capture, mileage tracking, basic tax estimates, and a clean mobile app designed for sole traders.

The trade-off: limited reporting, no invoicing beyond basics, need to upgrade for more features.

Verdict: the cheapest option from a major provider with a genuinely good sole trader experience.

Countingup (Free/Premium)

Price: free banking plan, Premium at around £9.99 per month.

What you get: business bank account with automated categorisation, basic tax estimates.

The trade-off: only tracks transactions through Countingup. Separate bank accounts are excluded.

Verdict: good value if you are willing to use Countingup as your only business account.

The Mid-Range Options (£10-£20/Month)

Accounted Starter

Price: £14 per month.

What you get: AI-powered bookkeeping through WhatsApp, bank feeds from any UK bank, receipt scanning via WhatsApp, mileage tracking, tax estimates, MTD compliance, cash flow forecasting, and proactive tax alerts.

See our pricing page for the full feature breakdown.

The trade-off: invoicing is still in development. Newer platform than Xero or QuickBooks.

Verdict: the best value if you want AI to handle your bookkeeping rather than doing it yourself. The time saved typically exceeds the cost difference from cheaper options.

Xero Starter

Price: approximately £15 per month.

What you get: bank feeds, basic invoicing (20 per month limit), bill entry (5 per month limit), bank reconciliation, MTD compliance.

The trade-off: invoice and bill limits on the Starter plan can be restrictive. Standard plan at £30 removes these limits.

Verdict: a solid entry point into the Xero ecosystem, but the limits push many users to the more expensive Standard plan.

FreeAgent (Standard Pricing)

Price: approximately £19 per month plus VAT.

What you get: comprehensive bookkeeping, invoicing, Self Assessment, MTD filing, bank feeds, reports.

The trade-off: more expensive than some alternatives and not the cheapest for what it offers unless you get it free through NatWest.

Verdict: a good platform at a fair price, but the value proposition is strongest when it is free.

The Cost of Cheap Software

It is tempting to choose the cheapest option, but there are hidden costs to consider.

Time is the biggest one. Cheaper platforms typically offer less automation, meaning you spend more time on manual data entry and categorisation. If your time is worth £30 per hour and you spend an extra 2 hours per month on bookkeeping, that is £60 per month in lost productivity, far more than the difference between the cheapest and mid-range options.

Missed tax reliefs are another hidden cost. Without proactive tax monitoring, you may not claim allowances you are entitled to. A single missed relief can cost more than a year of software subscriptions.

Errors are expensive too. Incorrect records can lead to incorrect tax returns, which can result in penalties from HMRC. The cost of correcting errors, both in accountant fees and potential penalties, quickly dwarfs software savings.

Price Per Hour of Bookkeeping

A useful way to compare is to think about effective cost per hour of bookkeeping.

With a free spreadsheet, you might spend 4-5 hours per month on bookkeeping. Effective cost per hour: free in software, but 4-5 hours of your time.

With QuickBooks Self-Employed at £8 per month, you might spend 2-3 hours per month. Effective cost per hour: about £3-£4 in software, plus 2-3 hours of your time.

With Accounted at £14 per month, you might spend 15-30 minutes per month (reviewing Penny's work and answering her questions). Effective cost per hour: £14 in software, plus minimal time.

The cheapest software is not always the cheapest solution.

Our Recommendation

If cost is your primary concern and you bank with NatWest, FreeAgent is free and comprehensive. Use it.

If you want the cheapest paid option from a major provider, QuickBooks Self-Employed at £8 per month is solid.

If you want the best return on your software investment, Accounted at £14 per month reduces your bookkeeping time to minutes, keeps your records perpetually current, and identifies tax savings you might otherwise miss. For most sole traders, it is the most cost-effective choice when you factor in time saved.

Sign up for Accounted and invest £14 per month to save hours every month.
