(And the 7 Traits That
Actually Matter)
I was working with a software
company in Amsterdam three years ago when the CEO pulled me aside with a
problem.
"Frank," he said,
"we just promoted our top salesperson to sales manager. She crushed her
quota every single quarter. Absolute legend."
"How's she doing?" I
asked.
He grimaced. "Three months
in, and the team's falling apart. Two reps have quit. Revenue's down 22%. She's
micromanaging everyone and still trying to close her own deals instead of
coaching her team."
"Let me guess," I
said. "You promoted her because she was your best seller?"
He nodded.
"That's your problem right
there."
This story isn't unique.
I've seen it play out in
boardrooms from Boston to Bangkok, Dubai to Dublin.
A company's top salesperson gets
promoted to manager, and within months, everything goes sideways.
The team underperforms. The
former star becomes frustrated. Everyone wonders what went wrong.
Here's the uncomfortable truth: Being
brilliant at selling and being brilliant at managing salespeople are completely
different skill sets.
Promoting your top seller to
manager is often one of the most expensive mistakes a business can make.
Research analysing over 50,000
sales employees found that top salespeople, when promoted to management, often
caused a decline in their team's performance.
Let me explain why this happens
— and more importantly, what traits you should actually look for in a sales
manager.
The Peter Principle in Action (And Why It's Destroying Your Sales Team)
There's a management concept
called the Peter Principle, first articulated in 1969 but still painfully
relevant today.
It states: "In a
hierarchically structured administration, people tend to be promoted up to
their level of incompetence."
People who excel in a given role
will tend to be eventually promoted into a new role that they won't be suited
for, and then remain stuck there because their apparent lack of competence
keeps them from being promoted any further.
The classic example?
A company promotes its top
salesperson to a sales manager role.
However, the new manager
struggles with delegation, team motivation, and strategic planning.
I've watched this disaster
unfold more times than I can count. The pattern is always the same:
1. Top performer exceeds quota consistently
2. Company assumes they'll be equally good at managing
3. They get promoted without proper training
4. They struggle because selling and managing require
fundamentally different skills
5. Team performance drops
6. Everyone becomes miserable
The kicker? High-performing
sales leaders were such a positive influence on their teams that they reported
an overall average annual quota attainment of 105% compared to 54% for
underperforming sales managers.
That's a 51% difference.
The right manager doesn't just improve performance — they transform it.
Why Great Sellers Often Fail as Managers
Let me be blunt about why this
happens.
Great salespeople succeed
through personal excellence. They're individually brilliant. They build
relationships, handle objections, close deals.
They succeed by being the best individual
contributor they can be.
Great managers succeed
through team performance. They don't close deals themselves — they develop
people who close deals.
They coach, strategize, remove
obstacles, and hold others accountable.
These are fundamentally
different competencies.
A top salesperson might:
• Work independently and thrive on autonomy
• Focus intensely on their own pipeline
• Rely on instinct and personal relationships
• Prefer doing over explaining
• Avoid administrative tasks
• Compete to be the best
A great sales manager must:
• Lead through others and develop talent
• Focus on the entire team's pipeline
• Build scalable processes and systems
• Coach others through repetition and patience
• Handle significant administrative responsibility
• Foster collaboration over competition
See the problem? The traits that
make someone an exceptional seller can actually work against them in
management.
I worked with a company in
Toronto whose top salesperson was a natural lone wolf.
Brilliant closer. Terrible at
sharing his methods.
When promoted to manager, he
couldn't understand why his team didn't "just figure it out" the way
he had.
His coaching sessions consisted
of "Do what I do" — which, of course, told them nothing useful.
Within six months, three of his
five reps were underperforming, and two had started quietly looking for other
jobs.
The 7 Traits That Actually Make a Great Sales Manager

Right, enough about what doesn't
work.
Let me tell you what actually
matters when identifying or developing sales managers.
After 25+ years training sales
teams globally, these are the seven traits I look for:
1. Coaching Ability Over
Personal Performance
The best sales managers
understand that their job is to make others successful, not to be the
hero themselves.
The skills that drive individual
success, such as consistently hitting quota, rarely translate into effective
team management.
Sales management demands
leadership, coaching, and strategic thinking — skills that differ entirely from
those needed for personal sales performance.
A great sales manager can watch
a rep on a call, identify three specific areas for improvement, and coach them
through practice until the new behaviour becomes natural.
They don't just say "do
better" — they show exactly how to do better.
I worked with a sales manager
in Melbourne who was never the top seller on his team.
But he was phenomenal at
breaking down complex skills into teachable steps. His team consistently
outperformed everyone else because he invested time making each person better.
2. Emotional Intelligence and
Empathy
Sales managers deal with human
beings who have bad days, personal struggles, different learning styles, and
varying levels of confidence.
You need to understand who your
reps are.
No two team members are built
the same — they're going to be receptive to different kinds of coaching.
If you can tactfully tailor your
messages and feedback to accommodate your reps as individuals, you'll put
yourself in an excellent position to be the best sales manager you can be.
The manager who treats everyone
identically will fail.
The manager who understands that
Sarah needs detailed guidance whilst Tom needs autonomy?
That manager wins.
One of the best sales managers
I've trained in Dublin had this incredible ability to read people.
She knew when someone was
genuinely struggling versus when they were making excuses.
She adjusted her communication
style for each person.
Her team would walk through
walls for her because they knew she genuinely cared about their success.
3. Strategic Thinking and
Process Orientation
Top salespeople often succeed despite
broken processes. They work around obstacles through sheer talent and effort.
Great managers? They fix the
processes so everyone can succeed.
There should always be some
rhyme and reason to your team's sales efforts — and the best managers know it's
on them to define and enforce what that will look like.
A strategic sales manager
doesn't just react to problems — they anticipate them.
They build systems for lead
qualification, deal progression, account management.
They create playbooks for common
scenarios.
I watched a sales manager in
Stockholm transform her team by implementing a simple qualification framework.
Instead of reps chasing any
opportunity that moved, they focused on prospects who fit specific criteria.
Win rate jumped 28% in three months.
Frank's
Quick Tip: If
you're evaluating someone for sales management, ask them to explain how they'd
improve your current sales process. Great individual contributors will say
"I'd just work harder." Great manager candidates will identify
specific process improvements.
4. Communication and Active
Listening
46% of buyers agree that
"active listening" is the number one skill they expect from sales
professionals; meanwhile, managers rank "active listening" as the
seventh skill they look for in an applicant.
That's a problem. Because sales
managers who can't listen can't coach effectively.
The best sales managers ask more
questions than they answer.
They listen to understand, not
to respond. They're genuinely curious about what's blocking their team.
Effective managers know how to
hear every side without playing favourites and make sure that disputes get
resolved constructively — minimising friction, maintaining high morale, and
ultimately making their teams run smoother.
One sales manager I worked with
in Singapore started every one-on-one by asking "What's going well, and
where do you need help?"
Then he actually listened. His
reps told him about obstacles he never would have known existed. He removed
those obstacles. Performance improved.
5. Accountability Without
Micromanagement
This is a delicate balance, and
it's where many new managers fail spectacularly.
Great sales managers hold people
accountable to commitments without hovering over every activity.
They trust but verify.
They measure outcomes, not just
activities.
The manager who checks CRM
entries obsessively but never asks "How can I help you close this
deal?" has it backwards.
The manager who sets clear
expectations, tracks results, and intervenes when patterns emerge? That's
effective accountability.
I saw a brilliant example in
Manchester.
A sales manager told his team:
"I don't care when you work or how many calls you make.
I care that you have 20
qualified opportunities in your pipeline every month and that you're moving
deals through our stages at the expected velocity. If you're hitting those
numbers, I trust your process. If you're not, we're going to dig into why together."
His team had the highest
satisfaction scores and the lowest turnover in the company.
6. Willingness to Make Tough
Decisions
If your leader starts avoiding
tough decisions or conversations, it's a sign they're not confident in their
ability to handle the responsibility.
Great sales managers don't avoid
difficult conversations. They have them quickly, directly, and compassionately.
They fire underperformers who
won't improve. They tell top performers hard truths about blind spots. They
push back on unrealistic demands from leadership.
I watched a sales manager in
Frankfurt do something that took genuine courage: He told the executive team
their aggressive Q4 target was mathematically impossible given current pipeline
and historical conversion rates.
He showed the data. He proposed
an alternative. They adjusted the target.
His team respected him
enormously because he protected them from unrealistic expectations whilst still
driving high performance.
7. Continuous Learning and
Adaptability
70% of US-based sales managers
agreed that managers' capability to adapt to change is more important now
compared to five years ago.
Markets change. Competitors
adapt. Buyer behaviour evolves. Great sales managers evolve with them.
48% of leaders are asking for
more training to become better coaches themselves.
In other words, sales managers
themselves understand the importance of learning new skills and honing their
existing ones.
The manager who says "this
is how we've always done it" is already obsolete.
The manager who constantly seeks
new approaches, learns from failures, and adapts strategies? That manager stays
relevant.
One of my favourite sales
managers — a woman I trained in Vancouver — spent an hour every Friday reading
about sales methodology, competitive intelligence, and market trends.
She tested new approaches
constantly. Her team always had the latest strategies whilst competitors were
still using outdated techniques.
The Bottom Line
Your top salesperson probably
isn't your best candidate for sales manager. They might be. But don't assume.
Many organisations assume their
top seller will excel as a manager.
However, the skills that drive
individual success, such as consistently hitting quota, rarely translate into
effective team management.
Instead of automatically
promoting your best seller, look for these seven traits: coaching ability,
emotional intelligence, strategic thinking, communication skills, balanced
accountability, decisiveness, and adaptability.
Sometimes your best manager
candidate is the person who was a solid B+ performer as a seller but has
natural leadership ability.
Sometimes it's someone from
outside your sales team entirely who has the right management competencies.
The cost of getting this wrong
is enormous.
Poor sales management can cost a
company up to £2.7 million annually.
The cost of getting it right?
A team that consistently
overperforms, reps who stay longer, and revenue that grows predictably.
I've trained thousands of sales
professionals across every continent. The pattern is always the same: Teams
with great managers thrive.
Teams with poor managers
struggle regardless of how talented the individual reps are.
So before you promote your next
top seller to manager, ask yourself: Do they have the seven traits that
actually matter?
Or are you just rewarding past
performance with a role they're not suited for?
Your team's future
performance — and your revenue — depend on getting this decision right.
