Welcome to Beyond the Handshake: Understanding the roles of business development, sales and marketing

Listen to this article

For the past decade, my work has revolved around one simple idea: real growth comes from real relationships. Not scripts. Not gimmicks. Just genuine human connection.

In this monthly column, I’ll share practical, real world ideas you can actually use – how to network and develop business without feeling awkward or salesy, how to build stronger and more intentional relationships, and how to turn everyday conversations into long term opportunities. The goal is straightforward: help you approach business development and networking with clarity, confidence, and a little enthusiasm.

I figured the best place to start is one of my favorite (and most misunderstood) topics:

What’s the difference between business development, sales, and marketing?

Business Development, Sales, and Marketing Walk Into a Bar…

If business development, sales, and marketing were people, they’d absolutely argue about who’s paying the tab.

Marketing would say, “I brought everyone here.” Sales would respond, “I convinced them to order.” Business development would quietly add, “I picked this place six months ago because it’s where the right people tend to show up.”

All three would be correct.

These roles are often lumped together, or worse, used interchangeably. While they work closely and sometimes overlap, they serve very different purposes. Knowing the difference saves frustration, improves collaboration, and avoids those uncomfortable moments that start with, “Wait … isn’t that your job?”

Let’s break it down.

Marketing: Setting the Stage

Marketing’s job is to make people care, ideally long before a salesperson enters the conversation. It builds awareness, shapes perception, and creates demand. Marketing answers questions like: Who are we? Why should anyone trust us? And why should they pay attention right now?

This includes branding, messaging, content, campaigns, events, and digital outreach. At its best, marketing doesn’t just promote a product or service, it helps people see a problem more clearly and recognize that a solution exists.

Good marketing creates clarity. Prospects show up to conversations informed, curious, and open, not skeptical and guarded.

Think of marketing as the opening act at a concert. If they do their job well, the audience is engaged before the headliner ever steps on stage.

Sales: Turning Interest into Action

Sales is where interest becomes revenue. It’s the most visible and measurable role of the three. Sales professionals work directly with prospects to understand needs, connect solutions to outcomes, navigate objections, and ultimately ask for the business.

If marketing creates demand, sales captures it.

Despite the stereotypes, sales isn’t just about “closing.” Strong salespeople listen carefully, ask good questions, and help buyers make confident decisions they won’t regret later. Trust matters here — without it, deals stall or fall apart.

Sales lives very much in the present. Pipelines, forecasts, and quotas drive the conversation. It’s less about “someday” and more about “does this move forward?”

Back at the bar, sales is the one convincing the bartender to pour the good stuff — and maybe throw in a discount.

Business Development: Playing the Long Game

Business development focuses on what’s next. Instead of chasing immediate transactions, it looks at long-term growth: strategic partnerships, new markets, referral relationships, and opportunities that don’t always fit neatly into today’s org chart.

Business development asks:

• Who should we be building relationships with?
• Which partnerships unlock credibility or scale?
• What conversations today could change the business a year from now?

Unlike sales, business development doesn’t always result in quick wins. Success might take months, or longer, and show up as a partnership, alliance, or steady pipeline that didn’t exist before.

If sales is about closing this quarter, business development is about opening doors for the future.

At the bar, business development is the one having a thoughtful conversation with someone two stools over, already seeing where that relationship could lead.

Where the Lines Blur

These roles naturally overlap, especially in smaller organizations where one person may wear all three hats. That’s normal.

The key difference isn’t who talks to customers, but why:

• Marketing sparks interest at scale.
• Sales converts interest into revenue.
• Business development creates new paths for growth.

When aligned, these functions work incredibly well together. When they’re not, confusion and finger-pointing tend to follow.

The Bottom Line

Marketing fills the room. Sales closes the deal. Business development decides which room you should be in next.

They’re not competing roles, they’re complementary ones. And when each understands its purpose, the entire organization moves forward with a lot more momentum… and far fewer arguments about who’s picking up the tab.

Now — about that check …
