Cranston

Accounting software that does the work.

Cranston prepares tax returns, closes books, and answers tax questions inside the tools your firm already uses. Cranston uses the same client data for every task, so it improves with each job. Your team reviews every judgment call.

How we build

One approach, across tax prep, tax planning, tax research, and bookkeeping.

We are engineers and accountants

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

Cranston prepares, your reviewers approve

Cranston prepares the work. Your reviewers approve it before Cranston posts it or sends it to a client, and before you file.

Inside the tools your firm already uses

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

Learns from live firm work

Firms use each feature in live client work. We decide which features to keep from their feedback.
