What we do

Compliance is the given. Advice is the value.

Keeping you compliant is about a quarter of what we do, and automation keeps it that way. The rest is advisory: cash, margins, reporting your whole team can use, and the big decisions.

The J and the B

We met by accident. We stayed on purpose.

We met by chance at a party in Aberdeen and were friends long before we were business partners.

Julita is the talker: outgoing, a people person, never happier than in a room full of clients. Bogna is the deep thinker, with a mathematical mind that loves a complex model. Opposites, and the perfect match.

That friendship is our advantage. We trust each other completely, share the load naturally and decide fast. It's how we run J&B, lead our team and look after every client, and it's why we keep growing.

We're a women-led firm, and it shows in the team: high-calibre accountants who value flexibility, and a culture that keeps them.
