Meet Butter, AI accounting for the self-employed
If you were a larger business, you’d hire an accountant, but currently, it’s just you. Butter handles your finances for you, from categorising transactions to tax calculations. Finances shouldn’t be a stressful part of your life; you’ve got enough going on.
✓ Live financial overview
View your business’ finances any time in the Butter app, and receive automatic monthly reports, and AI powered insights. Understand your financials without thinking.
✓ Automatic transaction reconciliation
Connect your bank account and Butter automatically categorises your transactions into the correct tax category, as they happen. Delete any that aren't related to your business and amend any you think are wrong, and Butter learns. Never categorise a transaction again.
✓ Optimised tax calculations
Butter has read the entire HMRC tax code—literally. Butter optimises your taxes and produces your tax calculations so that you can simply plug them into gov.uk (full integration coming soon).
Letter from the founders
Butter is built out of pain.
We’re app developers, but more importantly, we’ve been self-employed for many years, and consequently have become unfortunately familiar with Xero, Sage etc. Accounting for sole traders is… awful. We have got used to spending hours reconciling transactions, used to tax calculations we don’t fully understand, and used to not knowing what’s actually going on in our self-employed finances. How much did I make this month? How much did I spend? Are my financials trending in the right direction? No idea.
Recently, having just paid an accountant ~£600 to do our accounts, we began experimenting with using AI to analyse our finances. It turns out that super-intelligence handles self-employed finances impeccably. Since then, we’ve been working on Butter. We believe Butter can deliver genuinely enjoyable accounting to sole traders across the UK, and alleviate the most painful part of going solo.
We’d love for you to join the waitlist and give Butter a try as an early user, your feedback will be invaluable.
