The relationship with your accountant shouldn't be a mystery, and neither should leaving one. Switching is a routine, professional process: the new accountant requests clearance, information is handed over, and your filings carry on uninterrupted. No awkward conversation required.

These guides explain what happens after you accept a quote, how the handover between accountants works, how long a switch usually takes and what affects it, and the signs that it's time to move. If you're weighing up a change, the questions to ask before changing accountants is a good place to start.

  1. How Long Does It Take to Change Accountants?

    No fixed period applies to switching accountants.

  2. What Happens After You Accept an Accountant's Quote?

  4. When Should a Small Business Change Accountants?

    Change accountants when the relationship repeatedly fails on service, communication or capability, not over a single bad week. The reliable triggers are chronic slow responses, deadline scrambles, advice that never arrives, and a firm your business has outgrown. Persistent unease deserves action; isolated incidents deserve a conversation first.
