For most tradespeople, accounting software isn’t about managing a complex finance department. You need something that handles invoices quickly, stays on the right side of HMRC, and doesn’t require an accounting degree to use. If you’re registered under the Construction Industry Scheme (CIS), you also need a tool that understands deductions — which rules out a few popular options.
The short answer: FreeAgent is best for sole traders, QuickBooks handles CIS best, and Xero suits growing businesses with employees. But the full picture depends on how your business is set up.
Key Takeaways
- Most tradespeople need a tool that handles Self Assessment, VAT returns, and CIS — not all software does all three well
- Making Tax Digital (MTD) for VAT is already mandatory for VAT-registered businesses; MTD for Income Tax starts in April 2026 for sole traders earning over £50,000
- FreeAgent is free with a Natwest or RBS business account — the best starting point for most sole traders
- QuickBooks has the most capable CIS features of any mainstream accounting tool
- Tradify is a job management app, not accounting software — it pairs with Xero or QuickBooks rather than replacing them
- Sole traders under the VAT threshold (£90,000 turnover in 2026) can get by with free or entry-level tools; limited companies with employees need more
What Matters for Tradespeople Specifically
Generic accounting comparisons don’t account for the quirks of running a trade business in the UK. Before looking at tools, here’s what actually matters:
CIS support. If you work as a subcontractor on construction projects, deductions of 20% (or 30% if you’re not registered with HMRC as a CIS subcontractor) are taken before you’re paid. Your software needs to record these correctly and, if you’re a contractor paying subbies, file monthly CIS returns to HMRC. You can read how CIS works on GOV.UK.
Making Tax Digital (MTD) compliance. Since April 2022, all VAT-registered businesses must submit returns digitally. MTD for Income Tax kicks in from April 2026 for sole traders and landlords earning over £50,000 annually — with lower thresholds following in later years. Whatever software you choose must be HMRC-recognised for MTD. The full list of compatible software is on GOV.UK.
Mobile invoicing. Tradespeople often invoice from a van or on a job site. A decent mobile app isn’t a nice-to-have — it’s essential for getting paid faster.
Simplicity. You don’t have time to learn a complex system. The best tools surface what matters and hide what doesn’t.

FreeAgent — Best for Sole Traders
FreeAgent was built for UK freelancers and small businesses, and it shows. The dashboard gives you a clear view of what you owe in tax, what’s outstanding on invoices, and what’s sitting in your bank account. It files Self Assessment, VAT returns, and company accounts directly to HMRC.
The biggest advantage: if you bank with NatWest or RBS business accounts, FreeAgent is free as part of your account package. For sole traders just starting out, that’s hard to beat.
CIS support is basic — it records deductions suffered as a subcontractor but doesn’t handle contractor CIS returns. If you’re paying subbies under CIS, you’ll need a different tool.
Pricing: Free with NatWest/RBS business banking. Otherwise £14.50/month (sole trader), £24/month (partnership), £35/month (limited company).
QuickBooks — Best CIS Support
QuickBooks handles the full CIS workflow better than any other mainstream tool. You can record deductions you’ve suffered, calculate what to deduct from subcontractors, and file your monthly CIS300 return directly to HMRC — all from one place. QuickBooks is on HMRC’s list of recognised MTD software for VAT returns and is included in the MTD for Income Tax pilot. You can verify current compatibility on GOV.UK.
The mobile app is strong, and the invoicing is fast enough to do on site. For a plumber, electrician, or roofer working under the CIS scheme — whether as a contractor, subcontractor, or both — QuickBooks is the clearest choice.
Pricing: Simple Start from £12/month, Essentials from £22/month. A 30-day free trial is available.
Xero — Best for Growing Businesses
Xero is one of the most widely adopted cloud accounting tools in the UK for small and medium businesses. It connects to most major UK banks for automatic bank feeds, has a large library of third-party add-ons, and scales well as you take on employees or add services.
CIS support has improved but remains less fully integrated than QuickBooks — the CIS add-on handles calculations and submissions but feels bolted on. If CIS is central to how you work, QuickBooks is better. If your business is beyond sole trader stage and you need payroll, multi-user access, or project tracking, Xero earns its price.
Pricing: Starter from £15/month, Standard from £30/month, Premium from £55/month.
Sage Accounting — Best for Established Businesses
Sage has been the dominant UK accounting software for decades, and their smaller business product (Sage Accounting, formerly Sage One) is genuinely good. It handles VAT, Self Assessment, payroll, and CIS. The interface is less modern than Xero or QuickBooks, but it’s familiar to most accountants — useful if you work with one.
One advantage: Sage’s customer support is UK-based and available by phone. For tradespeople who’d rather call than read a help article, that matters.
Pricing: Starting from around £15/month; pricing varies by plan.
Wave — Free Option for Non-VAT Businesses
Wave is free accounting software that handles invoicing, income, and expense tracking. The catch: it’s not MTD-compliant and doesn’t support CIS. For a tradesperson who isn’t VAT-registered, doesn’t work under CIS, and is earning well below the MTD for Income Tax threshold, Wave can work short-term. But most tradespeople will outgrow it quickly.
Tradify — Job Management That Works Alongside Accounting
Tradify isn’t accounting software. It’s a job management app built for tradespeople — you create quotes, schedule jobs, track time, and invoice from one place. Most users connect it to Xero or QuickBooks for the actual accounting.
If managing multiple jobs, teams, and quotes is the headache rather than the accounting itself, Tradify is worth the extra cost. Many plumbers, electricians, and heating engineers use Tradify for day-to-day operations and Xero for the books.
Pricing: From around £35/month per user.

Frequently Asked Questions
Do I need accounting software as a sole trader tradesperson? You don’t legally need it, but HMRC’s Making Tax Digital rules mean most sole traders earning over £50,000 will need MTD-compatible software from April 2026. Even below that threshold, good software saves time on invoicing and tax prep and reduces the chance of a self-assessment mistake. If you’re setting up as a sole trader for the first time, getting accounting software in place early makes everything simpler.
What does CIS mean for my accounting software? CIS (Construction Industry Scheme) requires contractors to deduct tax (usually 20%) before paying subcontractors, and submit monthly returns to HMRC. Your software needs to handle both recording deductions you’ve suffered and filing returns if you pay subbies. QuickBooks handles this most fully of any mainstream tool.
Can I do my own self-assessment with accounting software? Yes. FreeAgent, QuickBooks, and Xero all file Self Assessment returns directly to HMRC. You’ll still need to check the figures are right, but the software does the calculation and the submission.
Is Xero or QuickBooks better for tradespeople? For most tradespeople working under CIS, QuickBooks is better. For businesses without CIS that have grown beyond sole trader stage and employ people, Xero’s broader feature set earns its higher price.
How much should I budget for accounting software? For a sole trader, £0–£15/month covers most needs (FreeAgent free with NatWest, or entry-level QuickBooks). For a limited company with employees, budget £25–£50/month. Add Tradify on top if you need job management. Note that if you employ staff, you’ll also need employers’ liability insurance — accounting software won’t remind you of that one.
Sorting out your accounting software is one of the less glamorous parts of running a trade business — but it’s worth getting right early. The same logic applies to your digital presence: a professional website and Google Business Profile are two of the highest-return investments a tradesperson can make. Digital Tradies builds websites for UK tradespeople from £49/month — no upfront cost, live in 3 days.
