The ability to see prospect/client engage far past the standard email tracking tool. Tinderbox allows you to see how many times the proposal has been opened, forwarded and it has a great electronic signature piece that all comes together to reduce speed bumps in the sales process.
UI could have an update but this tool was great while we used it.
Definitely worth taking a trial to experience this solution
Reduce unnecessary steps in the sales process and automating proposal delivery to prospects/clients.
