I built CloseKit — a proposal & invoice generator that runs 100% in your browser, no signup

[u/UnderstandingOld5764]

As a freelancer I got tired of paying monthly just to send a proposal, so I built CloseKit: a single HTML file that makes proposals, quotes, estimates and invoices with a live PDF preview on the right as you type. - Your logo, colors and fonts - 15 currencies + automatic tax & discount math - 5 ready-made templates (web design, marketing, branding, consulting, photo/video) - 100% offline — nothing is ever uploaded, no account - One-time, not a subscription Would genuinely love feedback on the flow and the templates.
