Cranston

Accounting software that does the work.

Cranston prepares tax returns, closes books, and drafts client requests inside the tools your firm already uses. The same client data supports every task, so Cranston improves with each job. Your team reviews every judgment call.

Built by production AI engineers and a CPA who ran his own firm.

Serve more clients with your current team.

Based in San Francisco.

Max & Sean

How we build

One approach, across tax prep, bookkeeping, and client follow-up.

Built by engineers and accountants

Engineers who built production AI work with a co-founder who ran his own accounting practice.

AI prepares, reviewers approve

The AI prepares the work. Your reviewers approve it. Nothing posts, files, or goes out to a client without review.

Inside the tools firms already use

Cranston works with the tools your firm already uses: QuickBooks, Xero, Drake, CCH Axcess, Lacerte, UltraTax, email, and shared files. There is nothing to replace.

Learns from live firm work
