About
Cranston is AI tax prep and bookkeeping for CPA firms. Our tax agents prepare returns the way a strong staff accountant would: they read the source documents, work the return in your tax software, and hand your reviewer a return that holds up, with workpapers attached. Our bookkeeping agents keep client books current all year, so tax season starts from clean numbers instead of cleanup. Prep and books are the start. We're building Cranston into the system a firm runs on: the place where prep, review, client requests, and the rest of the practice get done.
