Private by design
Your invoices never leave your Mac.
There's no account and nothing is uploaded. Your company profile, clients, invoices, and line items are stored only on your Mac, and template invoicing works fully offline. The one thing that ever leaves your machine is a note you choose to type into "Describe it" — and that goes straight to Anthropic using your own API key, never to a Tallyy server.
Pay once — not a subscription
$4.99, one time. Unlimited invoices.
One purchase unlocks the whole app — make as many invoices as you like, template or AI. It is a one-time purchase, not a subscription: no monthly bill, no auto-renew, and free updates.
Two ways to make an invoice
Templates — tap it in.
Choose a clean preset, add your line items, and Tallyy renders a professional PDF. Your company details autofill from Settings, so every invoice looks consistent without retyping a thing.
Or just describe it — with your own AI key.
Type a rough note like "3 hours design work for Acme, plus a $50 rush fee," and Tallyy's assistant asks about anything it's missing and drafts the whole invoice. "Describe it" uses your own Anthropic (Claude) API key — free to create, and you're billed by Anthropic only for what you use (a fraction of a cent per invoice). Template invoicing needs no key.
