The manager is the asset you forgot to manage
You hired a salesperson, sent them to product training, watched their numbers, role-played their phone-ups, and coached them weekly. Then they got good, you promoted them to the desk, and the coaching stopped.
That is the gap in most stores. The salesperson who outsells everyone becomes a manager and is handed a desk, a headset, and a deal log, and is expected to figure out the rest. Nobody teaches them how to develop a person, run a one-on-one, or hold a number without burning the relationship. They default to the only model they ever saw: chase deals, work gross, and grind.
A dealership's people are its most heavily invested and least managed asset, and the manager sits on top of that pile. One good GSM lifts ten salespeople. One untrained GSM caps them. If you only have time to coach one layer of your store, coach the managers, because they multiply everything.
Coach the behavior, not the board
The fastest way to stall a manager's growth is to manage them the way you manage the recap: by results only. "We were short eight units, what happened?" tells you nothing and teaches them nothing. By the time the number is bad, the behavior that caused it is two weeks old.
Coach the inputs instead. A manager controls a small set of daily behaviors, and those are what you inspect:
- How many deals did they personally T.O. and what happened on each.
- How many one-on-ones did they hold with their people this week.
- How many save-a-deal opportunities did they touch before the deal died.
- How many of their salespeople's phone-ups or appointments did they actually listen to.
Sample script for a weekly sit-down:
"Forget the board for a second. Walk me through the three deals you got involved in this week. Not the gross. What did you do, what did the rep do, and what would you do differently next time?"
That question develops a manager. "Why are we short?" just makes them defensive.
Run a real one-on-one with each manager
If you want your managers to run one-on-ones with their salespeople, you have to run one with them. They will manage the way they are managed.
Put a standing 30-minute weekly meeting on the calendar with each manager and protect it like a customer appointment. Do not cancel it for a hot deal. Canceling it teaches them that coaching is the first thing to drop when the store gets busy, and they will pass that lesson straight down to the floor.
A simple, repeatable structure:
- 1Their world first. "What is getting in your way this week?" Listen before you talk.
- 2Their people. Pick two of their salespeople by name. "How is each one developing? What is your plan for the weak one?"
- 3One number, one behavior. Choose a single metric that is slipping and the one behavior that drives it. Not ten. One.
- 4A commitment. End with what they will do before you meet again, in their words, specific enough to inspect.
When you name their salespeople and ask for a development plan, you signal that part of their job is building people, not just closing deals. Most managers have never been told that out loud.
Make them teach, because teaching exposes the gap
A manager who cannot explain the four-square, the road to the sale, or your save-a-deal process in plain language does not actually own it, and neither will their people. Teaching is the fastest diagnostic you have.
Hand them the Saturday sales meeting. Give them a topic on Wednesday and have them run a 15-minute training Saturday morning. Watch how they prepare and how they hold the room. You will learn more about a manager from watching them teach phone skills for ten minutes than from a month of recaps.
Sample handoff:
"You're running Saturday. Topic is setting the next appointment before the customer leaves. I want a script, one role-play, and a number you want the floor to hit this week. I'll be in the back."
Then debrief it. "What landed? Who checked out? What will you do differently next week?" Now you are coaching the coach.
Hold the standard without taking the wheel
The hardest skill for a GM is letting a manager struggle through a deal you could have closed in your sleep. Every time you grab the desk, you get the unit and lose the development. The manager learns that when it gets hard, you will take over, so they stop reaching.
The move is to coach the rep through their manager, not around them. When a deal is stuck, resist walking the desk yourself. Instead:
"What do you want to do here? Okay, try that. If it doesn't work, come back and we'll figure out the next move together."
You are still on the hook for the number. You just stop being the only person in the building who can hit it. A manager who closes a hard one on their own this month closes three on their own next month.
Do this Monday
- 1Put a recurring 30-minute weekly one-on-one on the calendar with each of your sales managers, and write "do not cancel" next to it.
- 2In the first meeting, ask each manager to name their weakest salesperson and walk you through a written development plan for that person.
- 3Pick one input metric per manager (T.O.s, one-on-ones held, save-a-deal touches) and start inspecting it weekly instead of only results.
- 4Assign the next Saturday sales meeting to one of your managers with a clear topic, then debrief how they ran it.
- 5The next time a manager brings you a stuck deal, ask "what do you want to do?" before you offer your move.
The takeaway
You spend money recruiting, paying, and retaining people, and almost all of it flows through your managers. An untrained manager quietly wastes that investment every day, capping good salespeople and pushing decent ones out the door. A coached manager compounds it. Coaching your sales managers is not a soft skill or a nice-to-have. It is the single highest-return thing a GM does with their week, because you are not improving one person, you are improving everyone that person touches.
