What your client opens is a live page, not a PDF: the trip on a map, photos of every stop, and one clear price, on their phone.
You spend real time building a trip. The right courses in the right order, a hotel you'd stay in yourself, an afternoon left free on purpose. Then you flatten all of it into a PDF, attach it to an email, and hope. The client downloads it once, opens it on a laptop, pinches at a map that won't zoom, and never opens it again.
An interactive proposal is the alternative. Instead of a document, the client gets a page.
Every proposal you send is a branded web page with its own link. The client opens it on their phone, because that's where they actually read things, and the trip is laid out to be read that way. There's nothing to download and no app to open. Nobody has to guess which version is the final one either, because there's only the one, live link.
The page carries the day-by-day itinerary, photos of the courses and hotels, and the whole trip drawn on a map so the client can see how it fits together. The price sits at the top as one all-in package number. It reads like a trip you'd want to go on, not a quote you have to decode.
The page wears your brand. Your logo, your colours, your cover photo at the top. Nothing on it says RoundPlan, because as far as the client is concerned there is no RoundPlan. There's your agency, and the trip you put together for them.
Your costs and your margin never appear on the page. Beyond that you choose how much detail to show: one all-in package price, which is what most agencies send, or the trip broken down line by line. If there's a row you'd rather not show at all, you can hide it without changing the price.
You don't publish blind. You can open the client's view exactly as they'll see it, check it reads the way you want, and only then share the link. What you preview is what they get.
A PDF in an inbox tells you nothing until somebody replies. The page tells you when the client first opened it and how many times they've been back since. A proposal nobody has opened in three days is a different phone call from one they've read four times.
The client approves the trip right there, with no printing and no chasing a signature over email. If something isn't right they ask for the change on the same page, and it arrives on the trip it's about, with the itinerary they were looking at sitting next to it. Either way it lands with you and the trip moves on your side. If they'd rather have it on paper, the page prints cleanly too.
Publish a proposal to share it as a live page in your own brand. The client sees one clear price and a map of the whole trip, and says yes with a click.
