Ai for accounting firms: the short answer.
AI can help an accountant draft variance explanations and review notes, summarize client documents, answer routine client questions from the file for staff approval, and draft request letters. A Stanford study found accountants using generative AI closed monthly books about 7.5 days faster. Tax data must stay inside a written security plan.
