Most invoice software products require email signup before you can PDF anything — even “free” tiers. That is a product category choice: cloud multi-user SaaS vs a local tool.
What “no signup” actually means here
- Open the site and bill immediately — no email gate
- Client and invoice data stay in this browser (IndexedDB / localStorage)
- Optional backups (.billlitz) and desktop folder links are under your control
- Optional app lock gates the screen only; it does not encrypt invoices at rest
If you need team seats, recurring subscriptions, or bank sync, a full SaaS suite may fit better. BillLitz is for freelancers and small businesses who want a tax-aware PDF without an account wall.
