Invoicing should take seconds — not subscriptions.
Every freelancer and small business deserves professional invoices without paying a monthly fee, creating yet another account, or handing their client list to a server farm. BillsZilla exists because the existing options forced an unfair trade: free tools that were too basic, or powerful tools locked behind paywalls.
BillsZilla runs entirely in your browser. When you type your business details, add line items, or pick a template, everything happens on your device. Nothing is uploaded, stored, or tracked on any server — we couldn't see your invoices even if we wanted to. Your drafts and saved invoices live in your browser's own storage, under your control.
BillsZilla is supported by unobtrusive advertising and occasional recommendations of accounting tools we think are genuinely useful. The generator itself will always be free — that's the whole point.
