Questions owners ask

Before you book, the usual questions.

Still unsure? Ask Ruth.

Partner, reporting. She takes most first calls.

Everything in the written scope: the work, the meetings and one named lead. If the scope changes, we agree a new fee in writing before any extra work starts.

Yes. Many clients keep their accountant for the year-end and use us for the monthly close or for tax planning. We agree who does what on the first call.

The scope arrives within three days of the call. Most monthly clients have their first close with us in the following month.

The partner named on your scope. You get their direct number and email, and they do the work, not a junior you have never met.

No. Most of our clients are in the South West, but we work by video with owner-run companies anywhere in the UK.

Monthly work runs on one month of notice. You keep every file, report and login, and we hand over cleanly to whoever comes next.

Twenty minutes with a partner, before you decide anything.

We tell you whether we are the right fit, who would lead your file and what the fixed fee would be.
