Xero vs QuickBooks vs Sage vs FreeAgent — which handles MTD best?

All four are HMRC-recognised for MTD. The key difference: Sage Accounting Start does not include MTD for Income Tax quarterly submissions — you need Sage Standard (£39+VAT/mo). Xero, QuickBooks, and FreeAgent all include MTD ITSA on entry-level plans. FreeAgent has the longest MTD pilot track record (since 2023). Xero launched the most advanced MTD AI data capture in February 2026. On compliance itself, all four are equivalent — the differences are in surrounding features and pricing.

Can I switch between Xero, QuickBooks, Sage and FreeAgent?

Yes — all four support data migration. Switching typically involves exporting your chart of accounts, opening balances, and transaction history as CSV and importing into the new platform. Most migrations take 1-2 weeks for small businesses. The exception is Sage 50 desktop to Sage Accounting — that’s the cleanest migration path if you’re a legacy Sage user. Switching from Sage Start to Sage Accounting requires a new subscription — you can’t upgrade directly.
