Proposal software that gets it signed
Write the proposal wherever you like. PropoBox sends it as a page under your name, shows you how it was read, tells you who to get back to, and takes it to signature and deposit.
Writing is the easy part now
An AI chat drafts a proposal in a minute. It cannot send it under your name, tell you the client read the pricing twice, keep the signed version, or put the deposit in front of them. That is the part PropoBox does.
What a chat cannot do
What the software does
Six jobs between your draft and the deposit.
Bring the proposal you have
Paste it from ChatGPT, Claude or a document, or upload the PDF, and it becomes an editable proposal. Templates and AI drafting are there when you start from nothing.
Send it as a page
An email from you with your own note and a link. The proposal reads well on a phone, needs no account, and replies come back to your inbox.
See how it is read
Every visit and its reading time, and on Pro and Business the part your client read longest. You are told when they open it and when they come back.
Know who to get back to
Your home screen lists proposals waiting on you, each with a suggested note or the next step: nudge, extend the date, or fix a bounced address.
Let the client decide on the page
Optional lines and quantities your client can change, a live total, and one typed or drawn signature that also accepts your own agreement, with a fixed record of what was accepted and a signature certificate.
Ask for the deposit at signing
Add your own payment link and a Pay button appears the moment they sign. You are told when the link is opened and mark the payment as received.
