Are you building your interior design business in a bubble?

If you’re anything like I was in my early years, you probably assumed the hard part was the design. You thought, “If I can create beautiful spaces, the rest will fall into place.” But what no one tells you is this: guesswork is expensive. Shooting from the hip on markups, contracts, pricing, and processes can cost you years of profitability—and a whole lot of stress.

In this episode, I sit down with award-winning interior designer and business educator Sonia Barney, founder of the Kaivari platform, to talk about why business support is not optional if you want a sustainable, profitable design firm. We unpack the role of coaching, personalized growth, business systems, and strategic mentorship in helping creative entrepreneurs skip years of trial and error.

If you’re starting out—or feeling overworked and underpaid—this conversation will help you see why investing in business education and the right coach can completely transform your creative career.

The Role of Coaching and Business Education in Your Design Business

If there is one theme woven throughout this episode, it’s this: you cannot build a profitable interior design business on talent alone. Creative skill will get you started—but business systems, mentorship, and strategic support are what sustain you.

Let me walk you through the key teaching points from our conversation.

1. Guesswork Is Expensive

Sonia said something that hit home: “Guesswork is expensive.”

In her early years, she was contracting projects based on assumptions. She was guessing at markups—10%? 20%?—without a clear understanding of industry standards or profitability targets. And like so many designers, she was working incredibly hard but not paying herself properly.

This is one of the biggest pain points I see with new interior designers. You think you’re saving money by not investing in coaching or business education. But in reality, you’re often losing money through underpricing, inefficient systems, poor processes, and reactive decision-making.

A good coach shortens your learning curve. Instead of five years of trial and error, you get proven templates, pricing structures, business strategy, and guidance that aligns with the interior design industry. That’s not an expense—that’s leverage.

2. Business Foundations Come Before Scaling

Sonia talked about working with foundational coaches—those who helped her understand basic business systems like processes, workflows, and financial tracking.

When she first heard words like “process” and “system,” she didn’t even know how they applied to a design business. And honestly? Many designers don’t.

But here’s the truth: if you don’t have documented processes for onboarding clients, managing projects, tracking expenses, and measuring profitability, your business will eventually feel chaotic. And chaos is not scalable.

Business education gives you structure. Systems create consistency. And consistency builds client trust and profitability.

You don’t need a huge team to start. In fact, Sonia shared that she still runs a small team. But what changed everything was implementing systems that allowed her to grow intentionally instead of reactively.

3. Different Seasons Require Different Coaches

One of my favorite parts of this conversation was the reminder that coaching is not one-size-fits-all.

Sonia worked with multiple coaches over the years—some focused on foundations, others on sales, speaking, bookkeeping, or strategy. Each coach served a different purpose depending on her stage of growth.

That’s important.

A brand-new interior designer needs different business support than someone scaling to a team of five. A designer struggling with sales conversations needs different mentorship than someone refining backend financial systems.

Personalized growth means aligning with the right expertise at the right time.

And just as important? Personality fit. Sonia emphasized how powerful it was to work with coaches whose teaching style and communication matched how she learns. That alignment makes implementation smoother and more effective.

4. Industry-Specific Support Matters

Not all business coaches understand the deceptively complex nature of the interior design industry.

From procurement and markups to project management and client psychology, our business is far more nuanced than many general business educators realize.

Sonia shared that while early support from general small business resources was helpful, it became clear that industry-specific coaching was imperative. When you don’t have to spend half your time explaining how interior design works, you get further faster.

This is why design mentorship and industry-specific coaching are so valuable. You’re working with someone who understands creative entrepreneurs, understands how revenue is structured in design, and understands the emotional and logistical layers of this career.

That kind of targeted guidance reduces friction—and increases profitability.

5. Community Normalizes the Hard Parts

Beyond one-on-one coaching, Sonia highlighted something equally important: community.

Interior designers are often solopreneurs. You work from home. You’re in your basement office. You don’t have coworkers to process challenges with. And it’s easy to fall into comparison mode, assuming everyone else has it figured out.

But when you connect with peers, you realize something powerful: everyone hits bumps.

Community networks normalize the struggles. They create space for sharing solutions. They allow you to learn vicariously from others’ coaching experiences. And they reinforce a growth mindset that keeps you moving forward.

Creative careers can feel isolating—but they don’t have to be.

Final Thoughts

If there’s one takeaway from this episode, it’s this: you don’t have to build your interior design business alone—and you shouldn’t.

Talent will open the door. But business strategy, coaching, and the right support system are what keep that door open and profitable. When you invest in business education, proven systems, and experienced mentors who understand the interior design industry, you dramatically reduce guesswork, protect your profit margins, and gain confidence as a creative entrepreneur.

That’s exactly why platforms like Kaivari exist. It was created specifically for interior designers who are ready for personalized growth, vetted coaching, and a trusted community network—all in one place.
