Really proactive accountants who really get startups. I've switched my businesses across and have appreciated the common sense approach and clarity on what we're paying for (with no surprises on costs!)

We've been using Novabook for a few months now and they have been awesome. Great, helpful team that goes above & beyond to take the day-to-day financial admin completely off my plate as a founder. Ruben and Steven have also been great sources of strategic financial advice & planning too. No brainer for founders.

The Novabook team are incredible. They understand startups better than anyone and are the dream to work with as a founder. Strongly recommend!!!

We really enjoy working with Novabook - Gus, Ruben, Andrea specifically. The team are young, agile, quick to respond and personable. They're not stuffy accountants stuck in 2002 and genuinely do things a bit differently. I'd definitely recommend working with them especially if you're a start up.

Superb job by Novabook. Been working with them for just 10 months, but the results are outstanding. For example, they expeditiously prepared and submitted our R&D Tax Credits, and for the first time we received the credit in record time. Highly recommend them for any startup, interested in speed, accuracy and automated workflow delivery.
