A record that matches what they saw
Acceptance stores the client's typed name, the exact time in Eastern, and a fingerprint of the proposal version accepted. If you change the proposal later, it becomes a new version — the accepted record never quietly changes underneath anyone.
Honest about what it is
QuoteMango acceptance is a client acceptance record, not a formal e-signature service. Your terms block, in your words, is what the client confirms — and the record shows they confirmed it, when, and on which version.
Declines and questions come back to you
A client who is not ready can send a question or decline with a note instead of going silent. You get the message immediately and can duplicate, revise, and resend as a new version.
Expiry handled gracefully
Past the validity date, the page says the price has expired and points the client to you. One tap from your dashboard extends it — no re-typing, no new link confusion.
