When is it a good idea to change accounting firms?

The beginning of the year is the best time to change accounting firms. With the closing of the fiscal year, new tax obligations, regulatory changes and financial planning, this is when many companies decide to outsource their accounting.
If your current accounting service does not meet your expectations - there are delays, lack of clear answers or growing tax risks - this is the perfect time to change your accountant or accounting office and gain peace of mind and full control over your finances.
