The Sage vs FreeAgent comparison is one of the most interesting in UK sole trader accounting because both platforms have genuinely compelling free options — Sage Sole Trader is free for non-VAT registered businesses, and FreeAgent is free for NatWest, RBS, Ulster Bank, and Mettle customers. Both are HMRC-recognised for MTD. The differences emerge in what each platform does best: Sage wins on invoice chasing AI and simplicity, FreeAgent wins on time tracking and direct Self Assessment filing.

Sage vs FreeAgent — the free tier comparison

The Sage vs FreeAgent free tier comparison is more nuanced than it first appears. Both have free options but they work very differently.

The practical verdict: if you don’t bank with NatWest Group, Sage’s free tier is more accessible. If you do, FreeAgent’s free tier is more capable.

Sage vs FreeAgent — frequently asked questions

Sage vs FreeAgent — which is better for UK sole traders?

The Sage vs FreeAgent decision depends on your situation. For non-VAT registered sole traders who don’t bank with NatWest Group, Sage Sole Trader is free and requires no bank account — the most accessible free option. For NatWest Group customers, FreeAgent is free and more feature-rich — time tracking, direct Self Assessment filing, and unlimited invoicing are all included. For freelancers and contractors who bill by the hour, FreeAgent wins on built-in time tracking. For sole traders with late-payment problems, Sage’s Copilot Payments Agent is the strongest AI invoice chasing tool available.

Sage vs FreeAgent — which is cheaper?

The Sage vs FreeAgent pricing comparison favours Sage for standalone paid plans — Sage Sole Trader costs £7+VAT/month vs FreeAgent’s £19+VAT/month standalone. That’s a £144/year saving. However, FreeAgent is free for NatWest Group customers, which beats both. For sole traders who need the full Sage Accounting platform (payroll, VAT, multi-user), the cost rises to £18+VAT/month — comparable to FreeAgent standalone.

Sage vs FreeAgent — which handles MTD better?

Both are HMRC-recognised for MTD for Income Tax. FreeAgent has the longer pilot track record — running since 2023. Both handle quarterly submissions reliably. The Sage vs FreeAgent MTD question is essentially a draw on compliance. The practical difference: FreeAgent provides direct Self Assessment filing within the platform; Sage Sole Trader requires you to file the annual return separately via HMRC’s website.

Sage vs FreeAgent — can I switch between them?

Yes — switching between Sage and FreeAgent is straightforward for small data sets. Export your transaction history as CSV before switching and import into the new platform. Note the Sage upgrade warning: you cannot upgrade directly from Sage Sole Trader to Sage Accounting — if you’re on Sage Sole Trader and want to switch to FreeAgent, you simply cancel Sage and set up FreeAgent. The reverse works the same way.

Sage vs FreeAgent — which has better AI?

Different strengths. Sage’s Copilot Payments Agent is better for invoice chasing — automating follow-ups and getting users paid 7 days faster on average. FreeAgent’s AI is better for tax — real-time Self Assessment estimates and automated transaction categorisation are more sophisticated. The Sage vs FreeAgent AI comparison depends on your primary pain point: late payers (Sage) or tax visibility (FreeAgent).

Sage vs FreeAgent — which is easier to use?

Both are designed for non-accountants. Sage Sole Trader’s interface is particularly stripped-back — intentionally simple for sole traders who just want to track income and expenses without complexity. FreeAgent is also simple but includes more features — time tracking, project management, and more detailed tax dashboards. For the absolute simplest experience, Sage Sole Trader edges ahead. For a complete feature set that still feels accessible, FreeAgent is the stronger choice.

Sage vs FreeAgent — our final verdict 2026

The Sage vs FreeAgent comparison doesn’t have a single winner — the right answer depends entirely on your situation.

Choose FreeAgent if: You bank with NatWest, RBS, Ulster Bank, or Mettle — the full platform is free and significantly more capable than Sage’s free tier · You bill clients by the hour and need built-in time tracking · You file your own Self Assessment and want direct HMRC filing · You have rental income alongside self-employment and need clear MTD guidance for both
