A sales rep who keeps missing quota puts pressure on the whole team. Most managers freeze between two bad options: coach harder, or start quietly building a case for termination. That hesitation usually comes from skipping one step: figuring out what is actually causing the numbers to slip before deciding how to respond.
Managing underperforming sales reps well starts with a fair, structured process rather than a gut reaction or a quick write-off. The right way to handle an underperforming rep is to diagnose the shortfall first: check whether it comes from a skill gap, a motivation problem, a broken process, bad leads, or a poor fit for the role. Then respond to that specific cause instead of using one generic fix for every rep. This article covers that process, from spotting the real reason behind low sales performance to tracking the right KPIs, building an improvement plan, coaching without wrecking morale, and deciding when it’s time to part ways.
Quick Calls, a US-based outsourced cold calling team, runs into this exact challenge across dozens of B2B sales floors every month. The same diagnostic steps below apply whether a rep works in-house or on an outsourced team.
Key Takeaways
Diagnose before you act, since underperformance is rarely just about effort or attitude.
Track leading KPIs, not just quota attainment, so problems surface while they’re still fixable.
A fair improvement plan needs specific goals, a set timeline, and consistent documentation.
Coaching works best when it starts with a rep’s self-assessment, not a manager’s lecture.
Use a four-factor test, performance, cultural fit, commitment, and competence, before deciding to let someone go.

Diagnose the Root Cause of Underperformance
Diagnosing the root cause means figuring out whether a rep’s low numbers come from ability, motivation, environment, or communication before choosing how to fix it. Underperformance usually falls into one of several buckets: a skill gap, a motivation or effort problem, a broken process or bad data, or poor lead quality, and each calls for a different response. A less obvious cause hides behind many of these: a communication breakdown where the rep doesn’t know what to do, how to do it, or why it matters. Treating every low performer the same way, whether that means more pressure or an instant write-off, wastes coaching time and rarely fixes the actual problem.
Identify the Skill, Effort, or Process Gap
Sorting a struggling rep into the right category starts with listening to their calls and reviewing pipeline activity side by side. A skill gap shows up as weak discovery questions, shaky objection handling, or thin product knowledge. An effort gap looks different: the rep knows how to sell but isn’t putting in consistent activity or follow-up. A process or data gap can mimic both, when bad leads or a messy CRM setup make success hard for anyone in that seat.
A few quick questions help narrow the category before any coaching conversation begins.
Does the rep know what a strong call sounds like, or are they guessing at the standard? If they can’t describe it, the gap is likely skill.
Are they logging the same call volume and follow-up as the team’s top performers? If the numbers match but results don’t, look past effort.
Would a new lead list or a different territory likely change their results? If yes, the process is probably the real issue.
Check If It’s a Role Fit Problem
Sometimes the honest answer is that a rep’s strengths don’t match what the role demands, no matter how much coaching happens. A relationship-driven rep who thrives on long-term accounts may struggle in a high-volume outbound seat built for speed, not depth. Role fit deserves an honest look early, since months of coaching won’t fix a genuine mismatch.
Track the KPIs That Reveal Low Sales Performance
Tracking the right KPIs shows whether a rep has a real performance problem or whether the numbers just look rough for a normal reason. Five metrics matter most: sales productivity, lead response time, average deal size, win rate, and quota attainment. Together they separate a genuine skill or effort issue from a market or process problem outside the rep’s control. A dropping win rate, for example, might point to pricing pressure or a slow season rather than a weaker rep.
| KPI | What It Measures | Red Flag To Watch For |
|---|---|---|
| Sales Productivity | Time spent actually selling versus admin work | Most of the day going to tasks outside real selling |
| Lead Response Time | How fast a rep follows up on a new lead | Response time creeping up while conversion drops |
| Average Deal Size | Revenue and effort tied to each closed deal | Deals landing well below the team average, or heavy discounting |
| Win Rate | Deals closed against deals in the pipeline | Win rate falling while lead volume and quality stay steady |
| Quota Attainment | Percentage of target hit each period | Most of the team missing quota, not just one rep |
Reviewing these numbers every week, not once a quarter, catches a slump while it’s still fixable and keeps the conversation focused on facts instead of impressions.
Build a Fair Sales Performance Improvement Plan
A fair sales performance improvement plan, following a documented template and examples for structuring goals and check-ins, turns a vague concern into specific goals, a set timeline, and a clear record of what happens at every check-in. Good structure protects the rep, since feedback becomes something they can act on instead of a mood or an opinion. It also protects the manager, since the plan shows exactly what was asked for, what changed, and what didn’t. The three steps below turn that structure into something a manager can build in an afternoon.
Step 1 – Set Clear, Specific Goals
The first step replaces vague feedback with a specific, trackable behavior. Telling a rep to be more confident on calls gives them nothing to practice. Asking them to keep call openers under 30 seconds gives them something to measure every day. Each goal should tie directly to one of the KPIs already being tracked, whether that’s response time, deal size, or a specific step in the call itself.
Step 2 – Define the Timeline and Check-In Cadence
A plan without a timeline drifts, so set a clear end date. Most plans run 30 to 60 days, long enough to show a real trend but short enough to keep urgency. Pair that end date with a daily self-review from the rep and a short weekly check-in with the manager. Frequent, short conversations catch a slip early, while one long monthly review usually arrives after the damage is done.
Step 3 – Document Progress and Next Steps
After every check-in, write down what improved, what didn’t, and the specific next action both people agreed to. This record does more than track history: it keeps the process fair by showing a consistent standard was applied at every step. When the plan ends, that documentation supports whichever call comes next: moving the rep off the plan, or making the harder decision to part ways.
Coach Underperforming Reps Without Killing Morale
Coaching an underperforming rep works better when it starts with their own view of the problem, not a manager’s lecture. Asking a rep to rate their own performance across a few key areas, then comparing that rating to the manager’s view, often surfaces the exact gap that needs closing. If a rep can’t see the gap themselves, coaching won’t stick until that awareness exists.
Good coaching also means asking whether the manager’s own style is part of the problem.
“Is there anything I could do to support you better?”
“How would you like to be managed?”
Questions like these often surface something worth fixing. Some outsourced sales teams, including Quick Calls, build this kind of structured call review directly into coaching, using recorded calls and a defined scorecard instead of vague impressions, a model in-house managers can borrow without outsourcing a single call.
Know When to Let a Rep Go
Deciding when to let a rep go gets easier with a framework that looks past quota numbers alone. Four factors give a fuller picture: performance and cooperation, cultural fit, commitment, and competence. A rep who struggles in one area but scores well in the other three is usually still worth coaching.
Performance and cooperation: are they consistently missing quota, and do they resist basic tasks like keeping the CRM updated?
Cultural fit: do their values match the team’s, and do they work well with the people around them?
Commitment: are they willing to put in extra effort when a goal actually requires it?
Competence: have they shown they can do the job, with the knowledge and focus it takes?
Would a genuinely strong performer struggle in this same role? Knowing everything now, would you rehire this person today?
Tolerating chronic underperformance far past this point costs more than one rep’s results, it tells the rest of the team that the standard is optional.
The Takeaway
Managing underperforming sales reps comes down to a repeatable order of operations. Diagnose the real cause first, track the KPIs that reveal the truth, and build a documented improvement plan. Coach with self-assessment before judgment, then use the four-factor test before making any final call. Moving fast through this process protects a rep’s dignity just as much as it protects the standard the rest of the team is held to.
Sometimes the underperformance comes down to capacity rather than skill: a thin pipeline, too few qualified leads, or not enough calling hours in the day. When that’s the case, teams can lean on a proven outbound structure while they rebuild their internal process. Quick Calls, for example, starts at $695 per month with no long-term contract, giving stretched sales teams extra calling capacity without the wait of a new hire’s ramp-up time.
Frequently Asked Questions
What Is A Sales Performance Improvement Plan And How Long Should It Last?
A sales performance improvement plan is a documented, time-bound plan with specific goals, a check-in schedule, and clear success criteria. Most plans run 30 to 60 days, long enough to show a genuine trend but short enough to avoid dragging out an unresolved problem.
How Do I Know If Underperformance Is A Rep Issue Or A Leadership Issue?
Look at the pattern first. If several reps struggle with the same metric, the cause is likely a process or leadership issue, not an individual one. If only one rep lags behind a team that’s otherwise hitting targets, the issue is more likely specific to that person.
What Percentage Of Sales Reps Typically Underperform On A Team?
Most sales teams, even strong ones, have a few reps missing quota at any given time. A handful of underperformers on an otherwise healthy team is normal and doesn’t mean the whole team or the manager is failing.
Should I Ever Skip The Improvement Plan And Let A Rep Go Immediately?
Skipping a formal improvement plan should be rare, usually reserved for integrity issues or a total lack of cooperation rather than a slow quarter. For ordinary performance concerns, a documented plan protects fairness for the rep and gives the manager solid footing if the decision is later questioned.
How Often Should I Review KPIs With An Underperforming Rep?
Weekly check-ins work well during an active improvement plan, paired with a quick daily self-review from the rep. Waiting for a monthly or quarterly review lets a small problem compound for weeks before anyone notices it needs attention.
Can Outsourcing Cold Calling Help Fix A Struggling Sales Team Faster Than Hiring?
Hiring and ramping a new sales development rep often takes three to six months, while an outsourced team like Quick Calls can launch calling campaigns within days. This works best when the issue is capacity, not a single rep’s performance gap, which still needs its own coaching plan.
