What your firm gets.

Cranston gives CPA firms one operating layer for tax prep, tax review, bookkeeping, client requests, and practice management. Your team keeps the client relationship and final judgment; Cranston handles the work behind it.

One system for client work

Cranston connects the files, messages, books, and tax data your team already works across.

It keeps source documents, QuickBooks or Xero data, prior returns, email context, client requests, and reviewer notes in one workflow instead of scattering work across portals and spreadsheets.

AI plus accountants

Use Cranston as software, or let our internal accountants operate it for you.

We can be the white-label back office for bookkeeping, tax prep, open-item cleanup, and client package assembly. Your firm stays in front of the client; Cranston moves the work to review.

Works on top of your stack

QuickBooks, Xero, TaxDome, Google Drive, Gmail, Drake, CCH Axcess, Lacerte, UltraTax, and the folders you still have to clean up.

We do not ask you to rip out the tools that already run the firm. Cranston sits on top, automates the manual handoffs, and keeps every output source-linked for review.

One operating layer for tax, books, client work, and review.

Cranston sits between the tools your firm already runs and the relationship you own, moving the repetitive work to a review queue in between.

Your firm

Client relationship, advisory conversations, and final sign-off stay with your team.
