AI back office
for your CPA firm.

Cranston runs on top of the software your firm already uses. AI prepares the work — tax prep, tax review, bookkeeping, client requests — and your reviewers approve it. Add our accountants when you want the work fully handled.

Takes under a minute. No rollout commitment.

Pilot scope

Bring one client workflow: a tax package, a monthly close, a client follow-up, or firm-wide status.

We'll show what Cranston can take over, and map the work into software, AI, and review controls.

Start narrow
Scale after the output is proven
Operating model

Your firm owns the client relationship, pricing, delivery, and final review.

Cranston sits underneath: AI prepares the work, your reviewers approve it, and your clients only ever see your firm.
