SOUND FAMILIAR?

Your started your business
to do what you love, not...

Chase your accountant for replies

You send an email and wait days for a response. When deadlines approach, the silence gets worse.

Spend evenings on admin

Receipts, invoices, reconciliations. The financial admin piles up while you try to focus on your clients.

Worry if you're profitable or not

Revenue comes in but you are not sure where it goes. You make business decisions without clear numbers behind them.

Keep track of tax deadlines

Making Tax Digital, corporation tax, self assessment. The deadlines keep coming and you are never quite sure what is due when.

you look after your clients

MEET HARRY

An accountant who understands business,
not just tax returns.

"Before starting ClearSum, I spent years as a Finance Director and Fractional CFO working alongside business owners. I kept hearing the same frustration with accountants who were unresponsive, reactive and disconnected from the day to day reality of running a business.


I started ClearSum to change that. With a commercial background and CIMA qualification, I bring a level of business understanding that most accountants don't. We look after the numbers, so you can look after your clients."
