Changing an accounting firm is not a procedure that is undertaken lightly. But sometimes everything does not go according to what has been agreed on or your bookkeeping needs have changed. This is an unfortunate situation that can be familiar to many entrepreneurs. In some cases there may be need for change, even if cooperation has been successful, due to changing service needs that the current accounting firm is unable to answer to.

The process might seem challenging at first glance, but it is not impossible. If possible, the change should be timed to the end of an accounting period, so that the new accounting firm can start from a “clean slate” and that the change can be done easily without the need to do all previous work twice. Sometimes however it is necessary to make a change immediately, at the middle of an accounting period. This is not an impossible task, but it requires more planning and foresight. We at Leinonen can help you at planning, so feel free to contact us if you require assistance in changing of accounting firms.

While switching between accounting firms, remember these details:

  • Seek out a new accounting firm before terminating contract with the current one.
  • From your current accounting firm, ask for the accounting material, journal, ledger, detailed profit & loss account and balance sheet.
  • Deliver all the accounting material from current accounting period and the financial statement of the previous accounting period, to the new accounting firm.
  • At the start of a new partnership, be prepared that the new accounting firm might have more questions than usual regarding your business. The operating methods might also vary greatly between different firms, so be ready to tell what kind methods suit you and what not.
  • Make sure that you know what kind of termination period you have with your previous accounting firm, so that there won’t be any unpleasant surprises.
