We started ApariSolo because tax shouldn’t feel like a mystery. Good software should give you a clear picture of where you stand, guide you through what’s next, and help you file with confidence.

Why we exist

“Tax technology should give you clarity and confidence, not more to worry about.”

“Tax technology should give you clarity and confidence, not more to worry about.”

Most people don’t find tax hard because the maths is difficult — they find it hard because it’s confusing, scattered across paperwork, and full of jargon. We built Apari to fix that: to turn your income, expenses and documents into a clear, organised picture you can actually understand.

We build two products from that same idea, for two different ways of managing tax.

ApariSolo · individuals

Guided Self Assessment and Making Tax Digital software that helps you organise your finances, see your estimated position and file with confidence.

ApariPro · professionals

Workflow technology built for accountants and tax professionals managing tax on behalf of their clients.

What we believe

The principles behind every product we build.

The principles behind every product we build.

✓

Clarity builds confidence.

You should always understand what’s happening with your tax and what comes next — no jargon, no guesswork.

✓

You stay in control.

Our software organises, calculates and guides — but you can always see how a figure was reached and review it before anything is filed.

✓

Trust is earned.

Through transparency, accuracy and honest communication — not overstatement or vague promises.

✓

Your numbers, explained.

We don’t just give you a result — we show you exactly what went into it.

Built on real tax expertise

Deep tax knowledge, turned into software anyone can use.
