Freelancers do not need another SaaS account to send an invoice. They need a clean PDF and a way to make it in two minutes.

I built a small invoice generator that runs entirely in the browser:

• add client and line items
• set tax and currency
• preview the invoice
• print or save as PDF
• no login, no upload

Try it: https://www.mengstone.com/invoice/

What it does not do

It is not accounting software. It does not file taxes, store invoices, or process payments. It just makes the document.

Why browser-only

Invoice data is boring but sensitive. Keeping it local means there is no server to breach and no account to cancel. The trade-off is that there is no sync or history.

If you send a few invoices a month, that trade-off is usually fine.
