Offline invoice generator

Create and print invoices even when the internet drops — after the first visit. No account. Data stays in your browser.

What "offline invoice generator" means

• First visit online: the app/generator loads and caches its shell.
• Later, offline: open the same URL, draft invoices, print to PDF if your OS print-to-PDF works offline.
• No cloud copy: we do not host your clients. That is the point of local-first software.

How to use it offline

1. Visit /generate or /app/ once while online.
2. Optional: install / add to home screen if your browser offers it.
3. Go offline — airplane mode is a good test — and create the invoice.
4. Print or Save as PDF. Email when you are back online.

Honest limits

• Buying Pro needs internet (Paddle checkout).
• License activation/recovery needs internet once.
• Clearing site data deletes local invoices — export backups.
• Not a government e-invoicing portal.

Who searches for an offline invoice generator

• Freelancers on trains, flights or patchy mobile data who still need to bill today.
• Consultants under NDAs who refuse to put client lists in yet another cloud SaaS.
• People tired of "free" tools that demand an email before showing a blank form.
