Our Mission

We believe managing finances should be simple, not stressful. Diagonlise was built to help UK freelancers and small businesses focus on what they do best while we handle the numbers.

Built for UK Freelancers

We understand the unique challenges of running a freelance business in the UK. From Self Assessment deadlines to tracking expenses for HMRC, we've designed every feature with your needs in mind.

Diagonlise was created by freelancers who were tired of complicated accounting software that wasn't built for sole traders. We wanted something simple, focused, and designed specifically for the UK tax system.
