Bill the hour. Keep the Sunday.
Stop losing Sundays to tax-advisory invoicing.
For boutique tax advisors billing by the hour, whether the deliverable is a planning memo, an audit response, or an Act 60 grantee structure. Log time. Direct the AI. Send the invoice. Five minutes. $99 a month, flat. Unlimited practitioners. Unlimited clients. 14-day free trial. Cancel anytime in the App Store.
Whether you're defending an IRS audit, structuring an Act 60 grantee, or drafting a transfer-pricing memo, the invoicing pain is the same. High-value hours logged in shorthand need to become client-ready prose that describes the work without leaking your strategy. Tax notes are confidential; invoice line items go to the client's business office. Getting the wording right takes hours you're not billing for. BillHour does it in one tap.

Is my client's tax data safe?
Supabase-hosted Postgres on AWS. Encrypted at rest, encrypted in transit with TLS 1.2 or higher. Row-level security means only your firm's users ever see your firm's records. On your iPhone, credentials sit in the iOS Keychain. Export CSV or delete your account anytime. Full policy at billhour.ai/privacy.
Does the AI understand tax-domain language?
Yes. Powered by Anthropic's Claude, which handles specialized vocabulary cleanly. Section 951A GILTI positions, IRS Section 7602 summons responses, Act 60 grantee compliance, transfer-pricing memos, and standard tax citations all sharpen into professional invoice prose. You approve every line before sending, so unusual citations get a human check.
Can I invoice international or expat clients in their currency?
Yes. Eight currencies, six languages. Set the language per project. Your team logs in it, the invoice ships in it. Lock the exchange rate at project start; the client is billed at that rate for the life of the engagement.
Can I export CSV for QuickBooks or my accounting stack?
Yes. Pro subscribers can export firm timesheet data as CSV for any date range. Hours, notes, projects, clients, and financials all included. Every invoice exports as a PDF. For a complete machine-readable export, email support@billhour.ai.
How do I cancel?
On your iPhone, open Settings, tap your name, tap Subscriptions, tap BillHour, tap Cancel. About ten seconds. Works during the free trial or anytime after. No forms. No email. No retention call.
