I've been dealing with this for years, yet last month I pocketed more than $8K in commissions.
Most of the items you mention are true. We do need to sell more units, however I'm a large market area, and also have lots of competition. Yes, prices are eroding, but you keep sane and realize there are clients that you can make GP on and those you can't. You need to identify who those clients are. You can do that by digging deeper, such as asking what manufacturer did they have before this one and or what dealer they did business with before the one they have now. This can establish brand and dealer loyalty. If it is there or not.
Value, there are clients that value our services and others that don't, many seem like they don't.
You need to add value, more on this later tonight, stay tuned.....
