Built for the
self-employed.
By one of them.

I watched my wife struggle with something that should be simple.

My wife is self-employed. Every year, the same story — receipts in a drawer, a spreadsheet that never quite adds up, and a nagging feeling that she's overpaying tax but not knowing by how much or why.

She'd pay a bookkeeper who'd skim the surface. File a return that was probably fine. And leave money on the table because nobody took the time to ask the right questions or explain what HMRC actually allows.

I looked for an app that could genuinely help her. Something that knew the rules, found the deductions, and gave her confidence instead of anxiety. I couldn't find it.

So I built it.

5 million sole traders. Most of them overpaying tax.

There are over 5 million self-employed people in the UK. Most of them are running their business alone — no finance team, no accountant on speed dial, no time to become a tax expert.

The tools available today were built for accountants, not sole traders. They track what happened. They don't tell you what it means, what you could have claimed, or what you should do next.

Nuxo is different. It's not bookkeeping software with an AI bolt-on. It's tax intelligence — built from the ground up to understand HMRC rules, surface every legitimate deduction, and give you a real-time picture of what you owe and why.

Tax intelligence. Not just bookkeeping.

Nuxo is built around one idea: you should never leave money on the table because you didn't know the rules. HMRC has hundreds of legitimate deductions available to sole traders. Most go unclaimed — not because they're hard to claim, but because nobody told you they existed.

We put AI at the forefront — not as a chatbot, but as a genuine financial companion that understands your business, knows the rules, and proactively surfaces what matters to you.
