The reason customer feedback gets lost in this industry isn't that customers don't talk — it's that the talk happens in three different inboxes, two text threads, and a phone call that nobody wrote down. By the time you're trying to remember whether they said yes to the wireless rear surrounds, the answer is in someone's deleted folder.
BidGlory's portal puts the conversation on the same page as the bid. A question about a line stays attached to that line. Every revision you send is kept and dated. Every approval records who signed, when, and which revision. When the install crew shows up six months later and the customer says “but I never agreed to that,” you have receipts that don't require an email-archaeology dig.
