The problem

Surprise tax bills destroy
cashflow and trust.

Year-end arrives. The CT bill is 40% higher than expected. For business owners it wrecks cashflow planning. For accountants, it costs client relationships. Rooby fixes this by keeping everyone looking at the same live numbers, year-round.

Without Rooby

Year-end shock. Manual estimates. Clients lose trust. Business owners scramble for cash.

With Rooby

Live forecasts. Money set aside. Proactive advice. No surprises at year-end.

Why Rooby

Built for accountants
and their clients.

Rooby isn't built by a tech company guessing at what accountants need. Every feature is designed around how accountants actually work — real client books, real CT600s, real trades-client headaches. It works just as well for business owners who want the same visibility as their accountant.

  • Trades-specialist logic, AIA timing, subcontractor signals
  • Accountant-first, you control what your clients see
  • Every calculation fully transparent, no black boxes, ever
  • UK data residency, your clients' data never leaves the UK

“We built Rooby because we were tired of the year-end scramble with our own clients. Now we see every liability move in real time, and our clients get proactive advice instead of a nasty surprise.”

    Amazing app!

    The perfect app to help me track my tax liabilities. I can't believe I didn't start using Rooby sooner. I recommend it to anyone who doesn't want to be caught short by surprise tax bills ever again!

    Really Useful App

    I use Rooby to track my tax liabilities for a company that rents out homes, found nothing else similar to it and is really easy to use!
