Frequently Asked Questions — UI/UX & Product Design

Does the PDF export preserve vector typography?

Yes! FastPay Studio generates true vector PDFs via jsPDF so your typography stays razor-sharp at any zoom level.

Why 100% Client-Side Billing Beats Cloud Subscriptions

Most “free” invoice generators bait you into filling out a form and hit you with a $15/month paywall or ugly watermark on the download screen. We built the exact opposite.

100% Local Browser Privacy

Your client names, rates, tax IDs, and banking details never leave your computer. Everything is processed in your browser and saved in localStorage.

Quote → Invoice → Receipt in 1 Click

Send an estimate with a digital signature pad, convert it to an invoice with a scannable payment QR code in 1 click, and issue a PAID receipt when the funds land.

Zero Watermarks, Supported by Coffee

Every vector PDF export is crisp, selectable, and 100% watermark-free. If this tool helps you get paid faster, you can support it with a voluntary coffee or PayPal tip.
