The hard part of a negotiated deal usually isn't the negotiation. It's everything after the handshake: drafting terms that are unambiguous, getting the desk to review them, getting the client to sign, getting an approver to sign off if the discount is aggressive, and getting it all keyed into a system that can actually charge it.
Today that path runs through email threads, a document with tracked changes, and a manual entry into the billing system once everyone has finally said yes. Every handoff is a place the deal can stall, and every stall is a client waiting on a bank that already agreed to the terms.
By the time the deal is live, weeks have passed, and the RM has spent more time chasing signatures than closing the next deal.
