Agency questions.
What size of agency do you work with?
Founders doing £100k to £10m, from new agencies to established teams with a group structure.
How do you treat media spend?
We separate media and other rebilled costs from your own fee income, so your margins reflect the work you actually do.
Can we start with Compliance and add Growth later?
Yes. Most agencies start with Compliance. Growth sits on top whenever you’re ready, with no lock-in.
Do you work with Xero?
Yes. We work mainly in Xero and FreeAgent, and can usually work with the tools you already use.
Can you help if we expand into the US?
Yes. Through our US partner firm, your US company set-up, tax filings and bookkeeping are handled there, while we look after the UK side, including the charges between your two companies.
