Where AI helps a accounting firm first
An accounting firm gets the most from AI by automating the chasing: missing documents, unsigned engagement letters, repeat client questions and deadline reminders. Technical judgment and sign-off stay with the CPA or preparer. Westward can build these pieces on the firm’s own accounts, with a person approving anything that goes out.
