Every accounting software website looks the same: smiling woman with laptop, five-star reviews, "£0 first month" banner. What matters for a self-employed UK tradesperson is actually narrower than the marketing suggests: does CIS just work, is Making Tax Digital covered, and can you raise a quote and an invoice from the van without fighting the app?
Six products a sole trader or small ltd construction firm would genuinely consider in 2026: QuickBooks Online, Xero, FreeAgent, Sage Accounting, Pandle and Countingup. Every one of them is HMRC-recognised for MTD VAT. Every one advertises CIS support. The difference is how deep that CIS support actually goes, and how much of the real work you can do on a phone.
Three things to look at before you pay for any of them:
CIS depth. Not all "CIS support" is equal. QuickBooks and FreeAgent handle the full lifecycle: deductions, monthly CIS300 filing, contractor payment-and-deduction statements, subbie reclaim, gross-status-ready. Xero, Sage, Pandle and Countingup have CIS features but the detail on HMRC filing and statement generation is less clearly documented on their own sites — check with your accountant before committing if you're filing CIS300 yourself.
Contractor AND subbie modes. If you're a sole trader subbie reclaiming tax at self-assessment, CIS is about statements-in and deductions-tracked. If you're a small ltd also paying subbies, you need CIS both ways — monthly filing to HMRC, verifying new subbies, issuing payment-and-deduction statements. Most providers do both, but FreeAgent and QuickBooks spell it out clearest.
Mobile depth. Every provider has iOS and Android apps. Where they differ: can you do the full job (quote, invoice, CIS-aware amount, receipt capture, expense categorisation) on the phone, or does CIS setup still live on desktop? Xero and QuickBooks are mobile-strongest. Pandle's mobile is more receipt-capture than full accounting.
Prices shift frequently — most providers run 3-6 month intro discounts that snap back to full rate. Figures below are standard monthly rates where the provider publishes them. Always check the live pricing page before buying. And if you bank with NatWest, Mettle or RBS, ask about FreeAgent before you pay for anything else — it's often free with the account.
