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.
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.
Designed and built for UK businesses
We believe powerful doesn't have to mean complicated. Every feature is designed to be intuitive and easy to use.
Your financial data is sensitive. We use bank-level encryption and never share your information with third parties.
We listen to our users and continuously improve based on feedback. Your success is our success.
