Frequently Asked Questions
Is InvoiceGen free?+
Yes. InvoiceGen is completely free with unlimited invoices — no trial, no watermark, no credit card.
Do I need to sign in?+
You can build and preview an invoice without an account. A free Google sign-in is only asked for when you download the finished PDF — it keeps the free tools sustainable and lets us improve them based on real usage.
Is my invoice data stored on your servers?+
No. Invoices are generated entirely in your browser and the PDF downloads straight to your device. Invoice contents (clients, amounts, line items) are never uploaded. If you sign in, only your basic Google profile (name, email, photo) is stored. See our Privacy Policy.
What can I download?+
A print-ready, high-resolution PDF of your invoice, rendered exactly as previewed — custom themes, logo and totals included.
Can QwickSpark build a custom invoicing or billing tool for my business?+
Yes — custom internal tools, billing integrations and automation are exactly what we build. Contact QwickSpark to discuss it.
