Cranston is tax prep and bookkeeping software for CPA firms. It fits firms that want to increase capacity without replacing QuickBooks, Drake, CCH Axcess, Lacerte or UltraTax—and still want a reviewer to make the final call.

## What it does

The workflow is unusually concrete. [Cranston’s homepage](https://cranston.ai/) says it reads source documents, enters returns in the tax software, attaches workpapers, flags missing or wrong-year documents, drafts client follow-ups, classifies transactions, reconciles accounts and queues exceptions. The practice-management layer keeps each client’s status in one place. Nothing posts, files or reaches a client until a reviewer approves it.
