How we make this list: we compare pricing pages, product documentation and public user reviews. Rankite is independent; if a vendor ever pays for a featured spot, that listing is clearly labeled Partner.
Key takeaways
- FreeAgent and Coconut are built for UK sole traders, with Making Tax Digital and Self Assessment filing baked in.
- Crunch pairs software with real accountants for traders who want the numbers handled.
- Xero, QuickBooks and FreshBooks are global platforms that work for sole traders but price for bigger ambitions.
- Wave and Zoho Books are the budget plays: free tiers that cover invoicing and basic books.
The best accounting software for sole trader
Sole trader accounting is a specific job: track income and expenses, send invoices, set aside tax, and file a Self Assessment (or Making Tax Digital updates) without hiring a finance department. The wrong software is either a spreadsheet that breaks at tax time or an enterprise system that charges you for features you will never touch. These eight options cover the UK-focused specialists and the global platforms, so you can match the tool to the business.
#1
FreeAgent
Best for: UK sole traders who want tax filing built into the software
Visit freeagent.com
Starting price£33/month (50% off first 6 months at £16.50; prices excl. VAT; see website)
Free planFree trial (30 days)
FreeAgent is designed around the UK sole trader's year: invoicing, expense tracking, bank feeds, and direct filing of VAT returns, Self Assessment and Making Tax Digital for Income Tax to HMRC. The homepage publishes pricing plainly: £33 per month (currently 50% off for the first six months), £330 per year annual, with a 30-day free trial and no hidden costs.
The standout detail is the banking tie-in: holders of NatWest, Royal Bank of Scotland, Ulster Bank or Mettle business accounts can get FreeAgent free. For UK sole traders who want one tool from invoice to tax return, FreeAgent is the most purpose-built option on this list.
What we like- HMRC-recognised with direct VAT, Self Assessment and Making Tax Digital filing
- Clear published pricing with a 30-day free trial
- Free for NatWest, RBS, Ulster Bank and Mettle account holders
Watch out for- UK-focused, so limited use if you trade internationally
- The headline price excludes 20% VAT
- Receipt-capture add-ons cost extra
Starting priceSee website
Free planNo
QuickBooks is the default recommendation in much of the world: invoicing, expense tracking, bank reconciliation, tax preparation and now AI-assisted forecasting and automated invoicing, all in one platform. The 800-plus integrations mean it connects to nearly every payment, payroll and ecommerce tool a growing business might adopt.
The homepage did not publish pricing, so check the vendor's site for current plans. For a sole trader, QuickBooks is more software than strictly necessary, but it is the safe choice if you plan to grow into a limited company or hire staff. Solo operators who will stay solo may prefer a simpler specialist.
What we like- The most widely used small-business accounting brand, with 800+ integrations
- AI features for invoicing, forecasting and automation
- Trusted by 10 million businesses per the vendor
Watch out for- Pricing is not published on the homepage
- The feature depth exceeds what most sole traders need
- Costs add up with payroll and add-ons
#3
Xero
Best for: Sole traders who want clean books with strong bank feeds
Visit xero.com
Starting price$25/month (Early plan; $2.50/month for the first 6 months, see website)
Free planNo
Xero's pitch is clarity: all your finances in one place, with invoicing, bank reconciliation, bill management and real-time reporting. The vendor publishes US pricing: the Early plan at $25 per month (currently $2.50 for the first six months), with Growing at $55 and Established at $90. The new JAX AI assistant answers cash-flow questions and creates invoices on request.
For sole traders, the Early plan's caps (20 invoices, 5 bills) are the thing to check against your volume. Xero is a beautiful generalist, but UK sole traders should compare its Self Assessment and MTD workflow against FreeAgent and Coconut before choosing on interface alone.
What we like- Published pricing from $25/month with an aggressive introductory offer
- Excellent bank reconciliation and invoicing
- AI assistant (JAX) for cash-flow questions and invoice creation
Watch out for- The Early plan caps invoices and bills, which growing traders outgrow
- No free tier
- UK-specific tax filing depth trails the UK specialists
Starting price$1/month for the first year (promotional; see website for current pricing)
Free planNo
FreshBooks built its reputation on invoicing for freelancers and service businesses: professional invoices, payment reminders, time tracking and expense organization, in an interface designed for non-accountants. The homepage currently advertises $1 per month for the first year, which makes it nearly free to try properly.
The promotion ends, so check the ongoing rate before committing. For sole traders whose accounting is mostly "send invoices, track time, record expenses," FreshBooks is the friendliest tool here. Those with inventory, payroll or complex tax needs should look at Xero or QuickBooks.
What we like- Promotional $1/month first-year pricing on the homepage
- Invoicing-first design that service businesses love
- 100+ app integrations and strong time-tracking
Watch out for- The $1 price is a first-year promotion, not the ongoing rate
- Accounting depth trails Xero and QuickBooks
- No free tier
#5
Wave
Best for: Sole traders who want genuinely free accounting and invoicing
Visit waveapps.com
Starting priceFree (paid add-ons such as payroll; see website)
Free planYes
Wave's proposition is blunt: free accounting software for small businesses, funded by paid add-ons like payroll and payments rather than subscriptions. Invoicing, accounting, receipt capture and basic reporting cost nothing, which makes it the cheapest credible option for a sole trader starting out.
The trade-offs are the usual free-tier ones: support, payroll and advanced features carry fees, and UK-specific tax filing is not its strength. For a new sole trader watching every pound, Wave covers the books for free while you validate the business. Upgrade to a UK specialist when tax filing season approaches.
What we like- Free accounting, invoicing and receipt scanning with no trial expiry
- Built for freelancers and solopreneurs, not accountants
- "get started for free" with no credit card
Watch out for- Free means paid support and advanced features cost extra
- Payroll is a paid add-on
- The free tier's limits and regional availability deserve a check
#6
Zoho Books
Best for: Sole traders already in the Zoho ecosystem or wanting a free plan
Visit zoho.com
Starting priceSee website
Free planSee website
Zoho Books is the accounting app inside Zoho's enormous business suite: invoicing, expenses, bank reconciliation, inventory basics and automation, integrated with Zoho CRM, inventory and 50+ other apps. For a sole trader who already uses Zoho tools, the integration argument is strong.
The caveat is verification: the vendor's homepage did not publish Books pricing or confirm free-tier terms, so check the Zoho Books page directly before deciding. UK sole traders should specifically confirm the Self Assessment and Making Tax Digital workflow, since that is where the UK specialists earn their keep.
What we like- Part of the 50-app Zoho suite, so it grows with the business
- Zoho's pricing is historically aggressive
- Strong automation and multi-currency support
Watch out for- The vendor homepage did not publish Books pricing or free-tier terms
- The suite's breadth can complicate a simple sole-trader setup
- UK tax filing needs verification
#7
Crunch
Best for: Sole traders who want software plus a real accountant
Visit crunch.co.uk
Starting priceSee website (fixed-fee packages; instant quote on the vendor's site)
Free planNo
Crunch is the hybrid: online accounting software backed by actual ACCA and CTA accountants who handle your Self Assessment, find allowable expenses and answer tax questions year-round. The vendor emphasizes fixed-fee pricing, MTD for ITSA compatibility and average tax savings for sole traders switching to Crunch.
This is for traders who would rather pay for peace of mind than learn bookkeeping. It costs more than FreeAgent or Wave, but the accountant is the product as much as the software. If tax makes you anxious and your affairs are not trivial, Crunch's model is worth the quote.
What we like- Real regulated accountants included, not just software
- Fixed-fee pricing with no surprise bills
- HMRC-recognised and Making Tax Digital compatible
- Tax-saving advice built into the service
Watch out for- It is a service with software, so it costs more than DIY tools
- Pricing requires an instant quote rather than a published price list
- UK-only
#8
Coconut
Best for: UK sole traders who want mobile-first tax and expense simplicity
Visit getcoconut.com
Starting price£99.99 (see website for current plans)
Free planFree trial (14 days)
Coconut is the minimalist's choice: a mobile-first app that connects to your bank, categorizes expenses automatically, tracks invoices and handles the UK tax workflow, including MTD quarterly updates and Self Assessment preparation. The vendor lists pricing around £99.99 with a free 14-day trial, and MTD annual submission add-ons are itemized honestly.
For sole traders with straightforward income and expenses, especially CIS subcontractors and landlords, Coconut's simplicity is the selling point. Complex businesses will outgrow it; everyone else gets tax compliance without the accounting degree.
What we like- Built specifically for sole traders, landlords and CIS subcontractors
- HMRC-recognised with MTD quarterly updates and Self Assessment filing
- Free 14-day trial with no card required
Watch out for- The mobile-first design suits simple affairs better than complex ones
- Self Assessment filing costs extra (£29.99)
- Narrower feature set than the global platforms
How we chose
We defined the category as accounting tools suitable for sole traders: invoicing, expense tracking, bank feeds and tax filing for the self-employed. We weighted UK tax capability (Self Assessment, Making Tax Digital) because "sole trader" is UK terminology and the brief's audience includes UK traders. For each candidate we opened the vendor's homepage and recorded pricing only where published; FreeAgent, Xero, FreshBooks and Coconut publish numbers.

Software only or software plus accountant
The real decision for sole traders is not which app, but how much help you want. DIY software (FreeAgent, Coconut, Wave, Xero, QuickBooks, FreshBooks, Zoho Books) costs less and keeps you in control; you do the bookkeeping and the software files the returns. Accountant-backed services (Crunch) cost more and remove the work; a human checks everything and advises on tax.
The honest test is your affairs and your temperament. Simple income, comfortable with admin: DIY software saves real money. Multiple income streams, CIS, property, or genuine tax anxiety: an accountant often pays for itself in found deductions and avoided penalties. Many traders start DIY and upgrade to an accountant when revenue justifies it; that is a sensible path, not a failure.
Choosing the right accounting software
Start with your country and tax obligations. UK sole traders: shortlist FreeAgent, Coconut and Crunch first, because Self Assessment and Making Tax Digital support is the feature that matters most and the global tools treat it as secondary. Elsewhere: QuickBooks, Xero, FreshBooks or Wave, chosen on invoicing needs and budget.
Then match the tool to the work. Invoice-heavy services: FreshBooks or Wave. Clean general books: Xero. Maximum ecosystem: QuickBooks. Already on Zoho: Zoho Books. Anxious about tax: Crunch. Simple affairs, phone-first: Coconut. Whatever you choose, connect the bank feed on day one, photograph every receipt, and set aside tax monthly: no software fixes records you never kept.
Frequently asked questions
Do sole traders need accounting software?
Legally, you need accurate records; software is not mandatory. Practically, Making Tax Digital for Income Tax is pushing UK sole traders toward digital records and quarterly updates, which makes compliant software close to essential. Even without MTD, software beats spreadsheets for invoicing, expense tracking and not dreading January.
What is Making Tax Digital and does it affect me?
Making Tax Digital (MTD) is HMRC's program requiring digital record-keeping and quarterly submissions. MTD for VAT already applies to VAT-registered businesses; MTD for Income Tax (ITSA) extends quarterly reporting to sole traders and landlords above the income threshold. FreeAgent, Coconut and Crunch are all HMRC-recognised and MTD-ready; confirm any other tool's status before relying on it.
How much should a sole trader pay for accounting software?
From free (Wave) to around £33/month (FreeAgent) for software alone, with accountant-backed services (Crunch) higher. The right budget is tiny relative to the cost of a missed deadline or unclaimed expenses: a single penalty or a few hundred pounds of found deductions dwarfs a year's subscription. Do not optimize the software price; optimize the tax outcome.
Can I do my Self Assessment through accounting software?
Yes, with the right tool. FreeAgent, Coconut and Crunch all support filing Self Assessment (and MTD updates) directly to HMRC. The global platforms handle the bookkeeping but may need an accountant for the actual UK filing. Check that your chosen tool files to HMRC directly before assuming it does.
When should a sole trader hire an accountant instead?
Consider it when your affairs get complex (multiple incomes, property, CIS, VAT registration), when tax anxiety costs you sleep, or when the accountant's fee is clearly less than the tax they save you. Many accountants offer a free initial consultation: take one before deciding the software alone is enough.
