Oprah - I can echo what TommyBoy said, and here's a bit more detail:
So if multiple Distys have the same product does this allow us to price check the various items?
You can see you pricing from all of your authorized suppliers on the product page, and you choose who to send the order to. Based on our data, there are several factors other than price that dealers choose to order from a specific vendor. We believe dealers choose vendors based on the following criteria, in order: 1) Stock availability, 2) Shipping (cost and timing), 3) Personal Preference (customer service, fast order processing, etc), and 4) Price.
When a client opens a proposal on the web portal are they able to markup questions/concerns etc that we can then read/respond to?
On the client version of the quote, when they scroll to the bottom they get the option to Accept or Request Changes. If they Request Changes, they can type what they'd like to do differently and that gets saved in your proposal history (in addition to the email notification you get).
