What is Interactive HTML Proposal Builder?

An interactive HTML proposal is a client-facing proposal page where pricing, optional add-ons, and scope details can be explored before approval, reducing back-and-forth and speeding decisions. Solo OS generates a single-file interactive proposal with editable sections, timeline milestones, and acceptance CTA routing via email or WhatsApp — all exportable from your browser.
