Marketing, Sales, or Business Development—Are You Investing in the Right One?

Consider these scenarios: 

Your business has new service offerings, but existing clients are confused, or worse, have no idea those services exist.

You see revenue slipping and need new customers fast. You hire a fractional CMO, but six months later there’s little impact: no change in inbound leads or activity from existing customers. What went wrong?

These are common business pain points, and they are often misdiagnosed. In most cases, it’s not a lack of effort, it’s investing in the wrong function at the wrong time. 

So what  actually drives that growth? And what roles do you need to support it?

This is nuanced, and there is no straightforward answer. Your business model, market, team, and budget all play a role. So do your growth goals and your ability to scale.

For today, let’s focus on three core functions: marketing, business development, and sales.

These roles often get blurred. Let’s clarify what each one does, when you need it, and what needs to be in place for it to work.

The Distinctions 

Marketing = Building clarity, awareness, and demand

What it does:

Marketing defines who you are, who you serve, and why it matters. It builds awareness, shapes perception, and creates demand by making your value clear and relevant to the right audience.

It also forces clarity around your value proposition—why someone should choose you over other options—and makes that visible in the market.

What it includes:

• Positioning and differentiation

• Audience definition and insight

• Messaging and value proposition

• Brand visibility and awareness

• Demand generation and client education

When you need it:

• People don’t understand your services

• You’ve evolved, but your market perception hasn’t

• You’re not generating the right type of inbound interest—or any at all

Business Development = Creating and nurturing opportunity

What it does:

Business development is proactive and relationship-driven. It identifies where growth can come from and builds the relationships that support it—across partners, prospects, and new markets.

It’s less about transacting and closing and more about creating access.

What it includes:

• Identifying target accounts and growth opportunities

• Building and maintaining relationships

• Developing partnerships and referral channels

• Expanding into new markets or service areas

When you need it:

• You want to grow into new markets or client segments

• You need to create opportunities, not wait for them

• Growth depends on relationships or long sales cycles 

Sales = Converting opportunity into revenue

What it does:

Sales converts qualified opportunities into clients. It manages the process from interest to decision and moves deals forward.

The key distinction: sales works with known opportunities—either inbound leads or active prospects. Depending on your business, sales may include revenue management and retention.

What it includes:

• Lead qualification and follow-up

• Managing the sales pipeline

• Proposals, pricing, and negotiation

• Closing and onboarding clients

When you need it:

• You have a steady flow of qualified leads

• Deals are stalling or not closing

• You need more consistency in how opportunities are converted 

Where This Usually Breaks

These functions don’t operate in isolation—but they often get treated that way.

Marketing, business development, and sales are meant to build on each other. But when the foundation isn’t clear, each function starts compensating for the others.

• Marketing creates visibility, but not the right kind

• Business development chases opportunities without focus

• Sales pushes deals that were never a strong fit

Everyone stays busy. Results don’t follow.

What Most Businesses Actually Need

The size and maturity of your business will inform your hiring or contracting needs. You don’t necessarily need all three functions at once.

You need:

• Clarity first

• Marketing to establish positioning and visibility

• Business development to create targeted opportunities (often led by leadership early on)

• Sales to convert once opportunity volume is there

The order matters more than the roles themselves.

If we revisit the scenarios outlined initially, if your clients don’t understand your new services, that’s not a sales issue—it’s a marketing gap. Your positioning and messaging haven’t caught up to your business.

If you hired a fractional CMO and saw no impact on revenue, the issue likely wasn’t effort. It was focus.  Either the work stayed too high-level, or it didn’t connect to how your business actually generates revenue. And if you need new clients—fast—you may need business development to create opportunities, supported by clear marketing, and sales to close.

Before hiring for marketing, business development, or sales, ask:

Can we clearly explain who we serve, what makes us different, and why clients choose us?

If not, start there.

If you’re working through these questions and not sure where to focus, that’s exactly where I spend my time.

At Make Progress Strategies, I harness my sales and business development background to help organizations get clear on positioning, align their marketing with how they actually generate revenue, and build a practical path to growth.

If this feels familiar, I’m always open to a conversation.
