For UK sole traders comparing Cuppa vs Kletta, both tools are designed for the same audience: self-employed individuals who need MTD compliance without full accounting software.
The main difference is price and automation level. Kletta Solo (the entry plan for sole traders) costs £19/month and leans on AI automation for bookkeeping. Cuppa costs £0 (free) or £4.50/month (Pro) and focuses on a clean, structured workflow you manage yourself. Both are HMRC-recognised and submit quarterly updates directly to HMRC.
For most sole traders, the core MTD workflow is the same in both tools. The question is whether AI automation is worth more than four times the monthly cost.

For a sole trader whose main requirement is MTD compliance, the price difference is significant. The question is whether the additional automation and mobile-first experience justifies the premium.
MTD Workflow Fit
Both tools are HMRC-recognised and handle the complete MTD cycle for sole traders: quarterly updates, end-of-period statements, and final declarations.
- Cuppa requires you to record income and expenses manually (or via bank import), review them, and submit. The process takes 10-15 minutes per week for most sole traders. You stay in control and understand your numbers at each step.
- Kletta uses AI to automate more of the bookkeeping, including categorisation. The aim is to reduce manual entry. Quarterly submissions are prepared and submitted automatically.
Both approaches result in compliant HMRC submissions. The preference for automation vs control is personal.

Setup and Learning Curve
Cuppa setup is minimal: add business details, configure income and expense categories, start recording. The interface is designed for non-accountants and takes most users under 10 minutes to set up.
Kletta setup involves configuring your income categories, reviewing automated transaction categorisations, and confirming initial settings. The automated workflow means less manual input day-to-day, but there is more to configure upfront. Bank connection with automatic imports is available on the Care plan (£49/month).
Switching From Spreadsheets
Cuppa:
- Import year-to-date income and expenses via CSV
- Confirm opening balances
- Start recording new transactions from today
- Quarterly submission available immediately
Kletta:
- Review and confirm automated categorisations for your income types
- Historical data import available
- AI begins categorising new transactions automatically
- Bank connection for automatic imports requires the Care plan (£49/month)
Both tools replace the spreadsheet. Cuppa's CSV import works regardless of which bank you use, with no plan upgrade needed.

Verdict: Which Should You Choose?
For UK sole traders who want reliable MTD compliance at the lowest possible cost, Cuppa is the clear choice. The free plan covers quarterly HMRC submissions. Pro at £45/year adds invoicing, bank integration, and amendment support. The workflow is designed for sole traders and requires no accounting knowledge.
Kletta is worth considering if you want AI to handle more of your bookkeeping automatically, you prefer a mobile-first experience, and the £19/month Solo plan cost is not a barrier. Its automation is genuine and the tool is well-designed for its target audience. If you also want automatic bank imports, the Care plan at £49/month includes that.
One-line rule: If cost and simplicity are your priorities, use Cuppa. If you want maximum automation and are happy to pay for it, Kletta is built for that.
