Most messages to an accounting firm are not tax questions. They are status questions: did you get my invoices, when is my VAT return due, what do you still need from me, has the payment gone through. They interrupt qualified staff all day, and the answer is almost always already in the practice management system or the document portal.
A small share are tax questions in status clothing. “Can I put my new car through the business?” is a question about advice, and the right answer depends on facts the desk does not hold and on a professional judgement the firm is liable for. General-purpose AI for tax questions will happily answer it anyway. This desk is built to recognise it and route it, with the conversation attached, to the accountant who owns the client.
