Before we get started

Do I need to be based in London?

No. We’re based in London and work remotely with clients across the UK.

Can you help with a one-off job?

Yes. You can come to us for a specific piece of work or ongoing support. Tell us what you need and any approaching deadlines, and we’ll agree what’s included before starting.

How much will it cost?

Our price calculator gives you an indicative range. We’ll confirm the work involved, review the condition of your records and agree a fixed fee for the defined scope before we start.

Can I keep using my current accounting software?

We work with a range of accounting systems, including Xero, QuickBooks, FreeAgent and Sage. Tell us what you use, and we’ll confirm how we can work with your setup.

What if I’m not sure which service I need?

Tell us what you’re struggling with and any deadlines you know about. You don’t need to choose a service or complete the calculator before contacting us. You can also book a free video consultation.

Can you help me switch from another accountant?

Yes. With your permission, we’ll contact your previous accountant and request the records we need. We’ll agree when we take over and who is handling any outstanding work or upcoming filings.

Tell us what you need done.

Send a short outline of the work and any dates in view. We’ll confirm the scope, fee and next step with you.
