FAQ
Is it really free?
Yes. No account, no per-invoice fee, no paid tier hiding the download button. A one-line credit at the PDF's foot is the only mark.
Where does my data go?
Nowhere. The PDF is generated by JavaScript in your browser — invoice contents are never uploaded. Your 'From' details are stored in your own browser's localStorage so you don't retype them.
Can I use my own currency?
Yes — the currency field is a free symbol prefix ($, €, £, ¥, CHF…). Amounts are formatted with standard two-decimal money math, computed in integer cents to avoid floating-point errors.
How do taxes and discounts work?
Discount is an absolute amount off the subtotal; tax is a percentage applied after the discount. Both show as their own lines on the PDF.
Can I automate this?
Yes — the same invoice engine is available as an API: POST JSON line items, get the PDF back. See the developer link below.
Sending invoices from code?
The same engine runs as an API: POST your line items as JSON, get the finished PDF back — correct money math, tax and discount handling, multi-page overflow. Invoice PDF Generator on RapidAPI (free tier available) or see all CalcWhale APIs.
