The tender is the scoreboard, not the game
Three positions, three different jobs
By the time an HVAC package goes out to tender the equipment schedule already exists, and your position in it is one of three things. You are the basis of design, named by model. You are listed as an approved equal, which means you are permitted but not preferred. Or you are absent, and the bid you are about to price is one you can only win on an equivalency somebody has to argue for. Those three situations need entirely different work, and the only reason most manufacturers respond to all three the same way is that nobody wrote down which one applies. Recording the position on the project makes the pipeline honest: the value-weighted forecast stops treating a job you are absent from as though it were half won.
The relationship you are actually building is with the consultant
The contractor places the order, but the MEP consultant decided what could be ordered, usually a year earlier, while sizing the load and writing the schedule. That relationship is built over many projects and is easily invisible in a CRM organised around purchase orders. Holding consultants as their own records, with the projects they have specified and how each turned out, lets an application engineer see that a particular firm has specified you on eleven jobs and dropped you on the last three — which is a conversation worth having before the fourth.
