Quick Dollar is a web-based app that helps U.S. freelancers and independent contractors create and send professional invoices in under a minute. It can automatically generate and attach a W-9, then deliver invoices by email and SMS with automated reminders. The app doesn’t process payments; instead, it includes your preferred methods—like Zelle, Cash App, Venmo, PayPal, or Apple Pay—so clients can pay you fast. A simple, template-driven flow gives clients everything they need up front to speed up payment
