About
Mastro Ledger
Bookkeeping software for CPA firms, made by Kieffer Taylor and Curtis Boortz.
Who makes it
Built to replace QuickBooks Online, for firms
Kieffer Taylor and Curtis Boortz started Mastro in 2026 so that a CPA firm, and every client it keeps books for, can leave QuickBooks Online completely. Every email to support@mastroledger.com reaches them.
- Bookkeeping software for CPA firmsA double-entry ledger for each client, with bank feeds, rules, reconciliation, the close, reports, invoices and bills, and a client portal.
- Four modules, per clientBookkeeping, Payroll, Tax Prep, and AI, each priced per client per month.
- Kept in the United StatesOn Mastro's own server in Hillsboro, Oregon, with encrypted backups every hour.
- Each firm's own accountsMastro never resells another company's service: the firm's Stripe, the client's bank, and each person's Claude are their own.
