How to Manage an Underperforming Sales Rep (Without Destroying Morale)

An underperforming rep is one of the hardest situations a sales manager faces. Miss quota long enough and the pressure comes from above. Move too fast and you damage someone's confidence permanently - or lose a rep who could have turned it around. Move too slowly and the rest of the team notices that standards are inconsistently held.

This guide walks through how to diagnose the actual problem, how to have the conversation, how to build a coaching plan that has a real chance of working, and how to make the call when it is not going to.

What Causes Sales Rep Underperformance?

Before you do anything else, diagnose. The intervention for a skill gap is completely different from the intervention for a motivation problem, and treating one as the other wastes time and makes things worse.

There are four root causes worth separating out:

1. Skill gap. The rep does not know how to do something - handle a specific objection, run a structured discovery, or build urgency without sounding pushy. This is fixable with the right coaching.
2. Knowledge gap. They do not know the product, the competitive landscape, or the buyer's world well enough to earn trust on a call. Also fixable, but the fix is different.
3. Motivation or belief gap. They have stopped believing the number is achievable, or that the product is worth selling, or that the manager has their back. Coaching alone does not fix this. You need a different conversation.
4. Process or territory problem. The list is bad, the ICP has shifted, or the rep is working a segment with a lower close rate than their peers. This is a management failure, not a rep failure, and it is more common than managers like to admit.

The fastest way to diagnose is to listen to their calls. Not one or two - at least five from the last two weeks. Look for patterns. Is the skill breaking down in the same place each time? Is the rep not getting to discovery at all? Is the prospect engagement low from the first minute? The call data tells you things that a 1-1 conversation will not, because reps adjust when they know they are being observed. Tools like Koachly's call scoring surface exactly where in the conversation a rep's performance drops - which turn in the call they lose momentum, how their talk ratio compares to peers, whether they are asking questions or presenting.

How to Have the Hard Conversation About Underperformance

Most managers put this conversation off too long because they know it will be uncomfortable. The longer you wait, the harder it gets and the less time the rep has to actually fix anything.

Prepare with specifics, not impressions

Do not walk in with "your numbers are down and I'm worried." That gives a rep nothing to work with. Walk in with three specific moments from their recent calls: the moment they skipped qualification, the moment they gave a discount before the prospect asked, the moment they lost control of the conversation. Specifics turn a performance conversation into a coaching conversation.

The right coaching questions make this easier. Ask the rep to replay the moment with you before you share your read. Most of the time they already know what went wrong. Getting to "you're right, I shouldn't have done that" takes 30 seconds when the rep is working from their own memory instead of defending against your interpretation.

Separate the behavior from the person

"You're not confident enough" is not useful feedback. "On the third call this week, when the prospect pushed back on timeline, you said 'I understand' and moved on - let's look at what a stronger response looks like" is useful feedback. The rep cannot change who they are. They can change what they say in a specific moment.

Get their read before you give yours

Ask them where they think the gap is. Ask them what they would do differently if they ran that call again. Feedback that a rep generates themselves lands completely differently from feedback that is handed to them. You are looking for shared understanding of the problem, not a performance of authority.

Building a Sales Performance Improvement Plan That Actually Works

A sales performance improvement plan - or PIP - gets a bad reputation because most of them are written as documentation for a termination rather than as a genuine attempt to help. A PIP that works looks different from one that does not.

The four-part coaching plan structure

Here is a framework that has a real chance of moving the needle in 30 days:

1. One skill, one metric. Do not ask the rep to improve everything at once. Pick the one behavior that, if it changed, would have the biggest impact on their close rate. Assign one metric that shows whether it is improving.
2. Weekly call review sessions. Use a specific call from that week, not your general impression. Look at structured 1-on-1 sessions to keep these focused and consistent. Fifteen to twenty minutes per session, anchored to a real moment.
3. Clear milestones, not just a goal. "Hit quota by the end of the month" is not a milestone. "Run three structured discovery calls that get to the economic buyer by week two" is a milestone. The rep needs checkpoints they can actually hit.
4. Written summary after each session. Not a formal document - a two-line recap of what you reviewed, what the rep is working on, and when you will check back. This protects both of you and keeps the rep accountable between sessions.

You can build and track this kind of structured plan inside the Koachly coaching plan view, which links session notes directly to the calls you reviewed so nothing lives in a spreadsheet disconnected from reality.

When to open a formal PIP

Move to a formal PIP when: informal coaching over four to six weeks has not produced movement, the rep understands the expectations and the gap, and the issue is a specific behavior or output that a reasonable person in this role should be able to achieve. Do not open a PIP as the first step when a rep has one bad month. That destroys trust with your entire team, not just the rep in question.

How to Manage an Underperforming Sales Rep Without Destroying Team Morale

The rest of your team is watching. They are not watching to see whether you fire someone. They are watching to see whether you handle it fairly, whether you actually tried to help, and whether your standards apply to everyone consistently.

Do not let it drag

The fastest way to destroy team morale is to let a persistent underperformer stay on the team with no visible response for months. High performers read that as "nothing matters here." Once they read that, you have a different problem entirely. Set a timeline, stick to it, and communicate it clearly to the rep.

Keep the process private, the standards public

Do not discuss a rep's performance issues with the team - ever. But do talk openly about what good looks like. Share call examples from top performers. Run team sessions on specific skills. When the team can see that standards exist and are applied to behavior on calls - not just to numbers - the fairness question answers itself.

Build a coaching culture before you need it

Managing underperformance is ten times harder if coaching is something you only do when something is wrong. If your team has a regular rhythm - weekly review, one skill, one call per rep - then improving performance is just the normal cadence, not a crisis. The best guide on how to coach sales reps consistently covers exactly this weekly structure.

How Long to Give a Rep Before Taking Action on Underperformance

This is the question every manager asks, and the honest answer is: faster than you think, with more structure than you are probably using.

The right timeline depends on the root cause

Skill gaps often show movement within two to three weeks of focused coaching. If a rep is not improving on a specific skill in that window, either the coaching is not working or the issue is not a skill gap. A motivation or fit problem often becomes clear even faster - usually within two weeks regardless of what you do.

The mistake most managers make is hoping the numbers will turn around on their own without addressing the underlying behavior. Numbers are a lagging indicator. The behavior on calls is the leading indicator. If you see the behavior improving, trust the process and give it the time it needs. If you do not see the behavior improving after three to four weeks of structured coaching, the conversation needs to change.

The conversation that has to happen at week four

If four weeks of focused coaching - real sessions, specific skills, weekly call reviews - has not produced any visible behavior change, you need to have an honest conversation about fit. Not as a threat, but as a genuine question: is this role, this product, this type of selling the right match? Some reps do better work somewhere else, and helping them see that clearly is doing them a favor.

Using Call Data and AI to Identify and Fix Sales Underperformance

The traditional approach to managing underperformance relies heavily on manager instinct and quarterly review numbers. By the time the numbers signal a problem, weeks of recoverable ground have already been lost.

Call data changes this. When you can see, across every rep's calls, exactly where discovery is breaking down, where objection handling is weak, or where a rep consistently loses momentum, you can intervene three weeks earlier with a much more specific plan.

Koachly surfaces these patterns across your team automatically. You can see which reps are spending too much time on price before they have established value, which ones are not asking second-level questions after an objection, and which ones have strong first calls but lose deals in follow-up. That information turns a vague "this rep is struggling" conversation into a "here are five calls from the last two weeks, here is the pattern I see, here is what we are going to work on" conversation.

Pair that with the call scoring feature to track whether coaching is working - not by waiting for the next quota number, but by watching the behavior on calls change week by week. When you can show a rep their own trend line improving, it is one of the most motivating things in sales management.

Performance improvement takes time. The manager's job is to give it the right structure, the right data, and the right amount of time - not too much, not too little. That combination is what separates managers who turn reps around from managers who just cycle through them.
