Cost for a solo freelancer

One freelancer's books cost a firm $30 a month as a single client book, but the client still needs a QuickBooks Online or Xero subscription and Cranston sells to the firm rather than to the freelancer.

One client entity's books, connected through QuickBooks or Xero. Each connected book is $30 per month. A client with two entities is two books.

Promotion and regular price

none — the two published rates are presented as the complete price list, with no introductory period, no discounted first months and no platform or onboarding charge named anywhere on the pricing page.

The two rates on this page are the full price list. You do not need a quote.

What it costs to keep your booksNo

Ledger included

The $30 book fee buys the AI work only: the client's ledger stays QuickBooks Online or Xero, whose own subscription the firm or client pays separately, and Cranston states it does not replace that system.

No. QuickBooks Online stays the client's accounting system. Cranston reads from it and prepares work for your firm's review.

What the price is based on

Billing is flat per unit of work: $30 each month per connected client book, plus a one-time $40 for each prepared return, with no per-seat, hourly or per-form element.

No per-form add-ons No hourly billing No per-seat charges No surprise charges

Users included

Staff seats are not metered: the pricing page rules out per-seat charges, and firm staff are instead managed by role as owner, admin or member with team-scoped access.

Past your plan’s limits

No transaction or account allowance is published for a book, so nothing is said about passing one; the only stated threshold is return volume, where past 2,000 returns a season the price is agreed with the vendor.

Every figure is the two rates multiplied by your counts. There is nothing else on the bill. Past 2,000 returns a season, we price the volume together.

cranston.ai/pricingChecked

What it costs to keep your booksNo

Setup or onboarding fee

The vendor states there is no onboarding or platform charge at all, so a firm pays only the recurring book fee and the per-return fee as returns are prepared.

Bookkeeping is the only recurring line. There are no platform fees or onboarding charges.

Catching up past months

Cleanup of messy prior months is offered as a project in which Cranston recategorizes and reconciles until the firm has a signable baseline; the pages put no separate price on that work.

Yes. Point it at the messy books. It recategorizes, reconciles, and flags what needs a human call until there is a baseline your firm will sign.

What the AI does with your booksYes

What the AI does

The AI reads client document packages, keys a first-pass return into the firm's tax software, classifies and reconciles ledger activity, works close checklists and answers tax questions with primary-source citations.

Cranston works with QuickBooks, Drake, CCH Axcess, and the rest of your stack. AI prepares the work. Your reviewers make the calls.

What the AI costs

included — the AI is the product itself and is covered by the two flat rates; the vendor states explicitly that nothing is metered in credits or tokens.

Pay per client book and per prepared return. Flat rates, no credits or tokens.

What the AI does with your booksYes

Categorizes transactions

Transactions sync from the ledger and are classified every day under the firm's own rules; a treatment decided once becomes a standing instruction that applies each month rather than needing re-teaching.

Reconciles your accounts

Bank and credit-card accounts are matched to statements, unmatched differences become reconciling items, and preparer and reviewer sign-off is recorded on each reconciliation for the firm.

Accrual books and reports

Cranston works each client's close checklist and generates the financial statements when the period closes, publishing them within days of month end; the pages do not name cash or accrual basis or list a cash-flow statement.

When a period closes, statements are generated within days of month end.

People check the books

Checking is the buying firm's own staff work by design: Cranston queues exceptions and findings, and nothing posts to a ledger, files or reaches a client until a firm reviewer approves it.

When the month is closed

The vendor commits to month-end output in the week the month ends, with reconciliations already run and only exceptions left for the firm's staff to clear before publication.

When the period closes, financials are generated and published to the client the same week the month ends.

Your accountant can sign in

Because the buyer is the accounting firm and seats are not charged for, reviewers and administrators can be added without extra cost, with access scoped by role and by team.

Accuracy the vendor claims

The vendor claims material errors in fewer than one draft in ten against four in ten for firm-prepared returns, and describes the method, but the figures come from its own internal study.

4 in 10 returns had an error that changed the tax owed. Cranston's software, given the same documents, made that kind of error in fewer than 1 in 10.

Files your tax return

Cranston prepares and keys a complete draft federal and state return at $40 per return, but stops short of filing: elections, sign-off and e-filing stay with the firm on its own EFIN.

SOC 2 report

There is no SOC 2 report to hand yet: the vendor says a Type II examination is in progress and names the live controls instead, offering a control walk-through with a founder rather than a report.

Your data trains AI

The agreement limits the vendor to using submitted taxpayer and financial data only to provide, secure, support and maintain the service, but neither it nor the privacy policy says anything explicit about AI model training or an opt-out.

Who it is built forYes

For accounting firms

The whole product is built for accounting firms, with many client books on one dashboard, firm-wide rules, role and team scoping and pages for solo, growing and multi-office practices; white-labeling is not claimed.

Cranston keeps each client's documents, books, returns, and email together so the next step is always ready.

cranston.aiChecked

Who it is built forYes

Several businesses

One firm account holds as many client books as it connects, and each additional entity is simply another $30 book, so a two-entity client costs $60 a month before its ledger subscriptions.

One client entity's books, connected through QuickBooks or Xero, is one book. A client with two entities is two books.
