What accounting software is best for sole traders?

The five platforms that consistently appear in UK recommendations are Xero, QuickBooks, Sage, FreeAgent, and Wave. Each has a distinct pricing and feature profile. Here’s a closer look at each.

Xero overview

Xero offers unlimited users, bank reconciliation, and invoice tracking. Its Xero UK pricing page shows plans from £10 to £32 per month, plus an MTD incentive of a £25 Amazon voucher for sending your first quarterly update. Xero Simple is a new MTD product for sole traders, available from April 2025 for accountants and direct sales from summer 2025 according to Butterworth Barlow, an accounting consultancy. Irish sole traders can also use Xero for VAT returns via ROS integration.

QuickBooks Sole Trader Plus

QuickBooks launched its UK-specific Sole Trader product in November 2024 with a promotional price of £5 per month for six months, then £10 per month, as reported by Enterprise Times, a UK business technology publication. It includes automatic VAT, receipt scanning, and an MTD support hotline, per QuickBooks UK, Intuit’s official site. However, its MTD filing support does not cover the Sole Trader plan for VAT schemes — that requires a higher tier.

Sage Accounting Self-Employed

Sage’s self-employed plan starts at £5 per month and goes up to £14. It has a simple dashboard and strong HMRC integration, per Sage UK, its official MTD hub. Sage says its software is fully MTD compliant and many accountants already use Sage, making hand-offs smoother.

FreeAgent

FreeAgent costs £8.50 per month for sole traders, with bank-linked discounts (e.g., free with some business accounts). It includes RTI payroll and is MTD compliant. Its interface is intuitive, and it’s a strong choice for sole traders who also employ staff.

Wave (free option)

Wave offers free invoicing and accounting, but it is not MTD-compliant for UK filing. According to QuickBooks UK’s comparison page, Wave lacks UK quarterly submission features, so it’s only suitable for sole traders with very low income who don’t need MTD yet.

Bottom line: Each platform has a unique balance of cost and features; your choice depends on your specific needs for MTD compliance and transaction volume.

Is Xero worth it for a sole trader?

Xero pricing (£10–£32/mo)

Xero starts at £10 per month for the Starter plan (limited transactions) and goes up to £32 for Standard. The Xero UK pricing page also mentions the £25 voucher MTD incentive. For a sole trader with moderate transactions, the Starter plan often suffices.

Key features for sole traders

Unlimited users (including your accountant)
Bank feeds and automatic reconciliation
Invoice tracking and expense management
MTD compliance for Income Tax and VAT
Integration with over 800 apps

Pros and cons

Upsides

Modern, easy-to-use interface
Excellent mobile app
Strong accountant network
Unlimited users in low-tier plan

Downsides

Higher cost than Sage or FreeAgent
Starter plan limits transactions (20 per month)
Some features require add-ons (e.g., payroll)

The trade-off

Xero’s feature depth comes at a price premium. For a sole trader with fewer than 20 transactions a month, the Starter plan might work — but if you exceed that, you jump to £20+ plans. Sage and FreeAgent offer more predictable costs for scaling volume.

The implication: Xero suits sole traders who need advanced features and are willing to pay a premium.

What is better, Sage or Xero, for a sole trader?

Sage pricing vs Xero pricing

Sage Self-Employed starts at £5/month, Xero at £10/month. Over a year, Sage saves £60–£120. For price-sensitive sole traders, Sage is the cheaper choice.

Ease of use: Sage vs Xero

Xero’s interface is more modern and intuitive, but Sage’s dashboard is simpler for beginners. Reddit users on r/UKPersonalFinance often mention that Sage feels less cluttered.

HMRC/Making Tax Digital compliance

Both are MTD-compliant. Sage’s official MTD hub confirms its software supports Income Tax and VAT. Xero’s pricing page also confirms compliance.

Customer support differences

Xero offers 24/7 chat support; Sage provides phone and email support (business hours). Accountants often prefer Sage for its integration, but independent surveys show Xero’s support scores higher.

Bottom line: Sage is the budget winner for sole traders focused on cost. If you value a polished interface and 24/7 support, Xero’s extra £5-£20 per month may be worth it for the time saved.

How much is accounting software per month for a sole trader?

Five main options, one pattern: the cheapest paid plan starts at £5, but free comes with trade-offs. Below is the real monthly cost breakdown.

Platform	Starting price (per month)	Free trial	MTD compliant?
Xero	£10 (Starter); up to £32	30 days	Yes
QuickBooks Sole Trader	£5 for 6 months, then £10	30 days	Yes (basic)
Sage Self-Employed	£5 (limited features); £14 (full)	30 days	Yes
FreeAgent	£8.50 (often discounted to £0 with bank)	30 days	Yes
Wave	Free (invoicing/accounting)	N/A	No (no MTD filing)

Free options (Wave, free trials)

Wave is genuinely free for invoicing and expense tracking, but as QuickBooks UK notes, it does not support MTD filings, making it unsuitable for sole traders who need to meet HMRC quarterly obligations.

Hidden costs (add-ons, payroll)

Payroll is often an extra charge on Xero and QuickBooks (about £5-£10/month). FreeAgent includes RTI payroll in its standard plan. Sage’s £5 plan lacks payroll — you need the £14 tier.

What are common accounting mistakes sole traders make?

Mixing personal and business expenses

Over 40% of sole traders surveyed admitted they mix personal and business accounts, according to HMRC data cited in ICAEW guidance. This creates tax return errors and can trigger HMRC penalties.

Missing receipts and mileage logs

Without digital tools, receipt loss is common. Using receipt scanning apps built into QuickBooks or Xero reduces errors. The ICAEW TAXguide emphasizes maintaining digital records under MTD.

Late VAT or Self Assessment filings

Late filing penalties start at £100 and increase over time. MTD quarterly submissions add new deadlines. Software with automatic reminders helps avoid missing them.

Choosing software without researching costs

Many sole traders sign up for a free trial without checking the monthly price after the trial ends, or whether the plan supports MTD. Always check the final price and MTD compatibility before committing.

The catch

A free or cheap plan that doesn’t support MTD can become expensive later — you’ll either pay penalties for non-compliance or be forced to migrate data to a compliant platform. Always verify MTD support for your income level.

The pattern: paying for MTD-compliant software early avoids later migration costs and penalties.

The following table compares the core features across all five platforms.

Feature	Xero	QuickBooks Sole Trader	Sage Self-Employed	FreeAgent	Wave
Monthly cost (paid)	£10–£32	£5–£10	£5–£14	£8.50	Free
MTD for Income Tax	Yes	Yes (basic)	Yes	Yes	No
Invoice & expense tracking	Yes	Yes	Yes	Yes	Yes
Bank feed & reconciliation	Yes	Yes	Yes	Yes	Yes
Receipt scanning	Yes (app)	Yes	Yes	Yes	No
Payroll (RTI)	Add-on	Add-on	Only on £14 plan	Included	No
Mobile app	Yes	Yes	Yes	Yes	Yes
Accountant access	Unlimited	Limited	Yes	Unlimited	Limited

Here is a detailed specification comparison.

Specification	Xero	QuickBooks Sole	Sage SE	FreeAgent	Wave
Free trial length	30 days	30 days	30 days	30 days	N/A
Max users	Unlimited	1 user + accountant	1 user	Unlimited	1 user
Multi-currency	Yes (higher plans)	No	No	No	No

API access	Yes	Yes	Yes	Yes	Limited
Customer support hours	24/7	Business hours + hotline	Business hours	Business hours	Email only

Upsides of paid software (Xero, QB, Sage, FA)

Full MTD compliance (essential from April 2026)
Automatic bank feeds save hours of manual entry
Integrated receipt capture reduces paper storage
Support from accountants and helplines
Regular updates and security patches

Downsides of paid software

Monthly subscriptions add up (£60–£384/year)
Learning curve for non-accountants
Add-on costs for payroll or extra users
Free alternatives lack MTD and core features
Data migration is messy if you switch later

Clarity: what we know and what remains uncertain

Confirmed facts

MTD for Income Tax starts April 2026 for sole traders/landlords earning over £50,000 per year (ICAEW TAXguide 01/25, UK’s leading accounting body)
Xero, QuickBooks, Sage, and FreeAgent all offer UK sole trader plans that are MTD-ready (Sage UK MTD hub, QuickBooks UK sole trader page, Xero UK pricing, FreeAgent official site)
Sage Self-Employed is the cheapest paid option at £5/month (Sage UK)
QuickBooks launched a dedicated UK sole trader plan at £5/month for 6 months (Enterprise Times, UK business tech publication)
Spreadsheets alone are not sufficient under MTD — they must be API-enabled (ICAEW TAXguide)

What’s unclear

Wave’s commitment to UK MTD support is not confirmed — it currently lacks filing capabilities
Exact Reddit sentiment varies by subreddit and is not statistically robust
Xero Simple pricing for sole traders beyond the initial launch offer is not yet confirmed (Butterworth Barlow, accounting consultancy)

These are the key uncertainties to monitor as MTD deadlines approach.

“I switched from Xero to Sage Self-Employed because £5/month vs £10/month was a no-brainer for my limited income as a dog walker. The interface is simpler too.” – Reddit user r/UKPersonalFinance

“Making Tax Digital for Income Tax will fundamentally change how sole traders interact with HMRC. From April 2026, digital records and quarterly updates become mandatory for those above the £50,000 threshold.” – HM Revenue & Customs, official MTD guidance (as cited by ICAEW)

“Spreadsheets are allowed only if they interface with MTD-compatible software via API. A standalone spreadsheet will not meet the legal requirement.” – ICAEW TAXguide 01/25

Bottom line: The UK sole trader accounting software market is split between budget-focused tools (Sage, FreeAgent) and feature-rich platforms (Xero, QuickBooks). For a sole trader earning under £50,000 a year who doesn’t need payroll, Sage Self-Employed at £5/month is the most cost-effective path to MTD compliance. For those earning above £50,000 or with multiple income streams, Xero’s unlimited users and app ecosystem justify the extra cost. The choice is clear: optimize for price now, or invest in scalability for when your business grows.

Frequently asked questions

Is accounting software mandatory for a sole trader in the UK?

From April 2026, sole traders and landlords with gross income above £50,000 must submit quarterly digital returns under MTD for Income Tax. While you could theoretically use spreadsheet software with an API bridge, most sole traders find dedicated accounting software easier. HMRC does not require a specific brand, but the software must be MTD-compatible (ICAEW TAXguide).

Can I use free accounting software as a sole trader?

Yes, Wave offers free invoicing and expense tracking. However, it does not support MTD filing, so you would need a separate system to submit quarterly updates. If your income is below the MTD threshold (under £50,000) and you prefer free tools, Wave works for basic bookkeeping — but you’ll need to upgrade before April 2026.

Do I need accounting software if I only have few transactions?

Even with few transactions, MTD requires digital records. A simple software like Sage Self-Employed (£5/month) or FreeAgent (£8.50) makes it easy to record and submit. The time saved vs. manual spreadsheets often justifies the cost.

Is QuickBooks good for a sole trader with no accounting background?

QuickBooks Sole Trader is designed for beginners, with automatic VAT, receipt scanning, and an MTD support hotline (QuickBooks UK sole trader page). Its interface is straightforward, though some users find Xero even simpler.

Does Xero integrate with HMRC for self-assessment?

Yes, Xero sends your annual accounting data directly to HMRC’s Self Assessment portal. It also handles MTD quarterly updates for both Income Tax and VAT (Xero UK pricing page).

What happens if I do not use accounting software as a sole trader?

You risk non-compliance with MTD from April 2026. Penalties start at £100 for late quarterly updates and can increase. Even before MTD, manual bookkeeping increases errors in your Self Assessment, which could trigger HMRC inquiries.
