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 by a practising accountant,
for accountants and their clients.

Rooby isn't built by a tech company guessing at what accountants need. It's built by a firm that manages real client books, files real CT600s, and deals with real CIS headaches every day. It works just as well for business owners who want the same visibility as their accountant.

  • Trades-specialist logic, CIS, DRC, 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.”
