How we work

After a career running finance functions, I know what business owners actually need from their accountant: accurate work, delivered on time, with no jargon.

1

Practical problem-solving

We start from your situation and your goals, then find the simplest compliant way to get there.

2

Diligence

Every figure is checked and every deadline is tracked, so you are never surprised by a penalty.

3

Modern tools

Cloud accounting and secure online working, so we can work together wherever you are.

Our green approach

Accounting with a lighter footprint

Good accountancy and caring for the environment go together. This is how we keep our own impact small.

Cloud, not paper

Cloud accounting software and secure online document sharing keep paper to a minimum.

Meetings without the miles

Video and phone meetings mean fewer journeys, for you and for us.

Common questions

What happens in the free consultation?

We talk through your situation, what is worrying you and what you need. I'll tell you honestly whether we can help and what the next step would be. There is no obligation to go further.

How much will it cost?

[FEES – add your approach, for example a fixed quote agreed after the free consultation]

Do you only work with clients in London?

No. I have strong connections in London and am there regularly, so we can meet in person by arrangement. Most of the work is done securely online, so we can work together wherever you are.

Which accounting software do you use?

We work with cloud accounting software such as Xero. If you already use something else, tell us and we can talk it through.

Can you take over from my current accountant?

Yes. We handle the professional handover with your previous accountant and ask them for the records we need, so you don't have to chase.

I've missed a deadline or received a penalty. Can you help?

Yes, and the sooner you tell us the better. We'll find out exactly what has happened, explain your options and deal with HMRC or Companies House for you.
