How to Outsmart Your Competition Using Porter’s Five Forces

6 days ago
3 min read

In today’s fast-moving business environment, competition isn’t always obvious. It’s not just the shop down the street or the business with the best marketing budget. Often, it's hidden forces—shifting customer power, new substitutes, or supplier constraints—that quietly erode your profits.


That’s where Porter’s Five Forces comes in. This strategic tool helps you zoom out and see the bigger picture of your industry so you can defend your margins, spot threats early, and build a long-term growth strategy.


What Is Porter’s Five Forces?

Developed by Harvard professor Michael Porter, this model helps businesses understand the five forces that shape competition in an industry. These forces impact pricing, profitability, and growth potential.


Here they are:

  1. Rivalry Among Existing Competitors

  2. Threat of New Entrants

  3. Threat of Substitutes

  4. Bargaining Power of Suppliers

  5. Bargaining Power of Customers (Buyers)


Now let’s break them down with examples and actionable tips for business owners and SMEs.


1️⃣ Rivalry Among Existing Competitors

The more saturated your market, the more aggressive the competition—and the harder it is to stand out.


Ask Yourself:

  • How many direct competitors do you have?

  • Do they compete mainly on price, or offer unique services?


What You Can Do:

  • Differentiate: Don’t race to the bottom. Focus on your value proposition—faster delivery, better customer service, or niche expertise.

  • Niche Down: Serve a specific audience better than anyone else.


2️⃣ Threat of New Entrants

When it’s easy for new players to enter your industry, your profits are always at risk.


Ask Yourself:

  • What are the barriers to entry in my field?

  • Can someone easily copy my model and start tomorrow?


What You Can Do:

  • Build brand loyalty through consistent service and storytelling.

  • Use technology or systems that give you operational efficiency.

  • Secure supplier or distribution agreements others can’t easily access.


3️⃣ Threat of Substitutes

Your competition might not even be in your industry. Substitutes are alternative ways customers solve the same problem.


Example: A small event planner might lose customers to DIY event platforms like Canva or online event kits.


Ask Yourself:

  • Are there cheaper or more convenient alternatives to my product or service?


What You Can Do:

  • Focus on added value—personalisation, peace of mind, convenience.

  • Educate your market on what makes you different and better.


4️⃣ Bargaining Power of Suppliers

Suppliers with too much power can increase costs or reduce flexibility.


Ask Yourself:

  • Do I rely on a single supplier?

  • Are there alternatives I can switch to?


What You Can Do:

  • Diversify suppliers to increase negotiation power.

  • Collaborate for better terms or explore local sourcing to reduce dependency.


5️⃣ Bargaining Power of Customers

In highly competitive markets, customers call the shots. They can shop around, compare prices, and demand discounts.


Ask Yourself:

  • How easy is it for my customers to switch?

  • Are they price-sensitive?


What You Can Do:

  • Create loyalty programs and perks for repeat clients.

  • Offer bundled services or convenience that’s hard to match.


Practical Use Case: How a Small Consultancy Applied Porter’s Five Forces


One of our HM Accounting clients—a boutique HR consultancy—was struggling to attract and retain clients.


By applying Porter’s Five Forces, we helped them:

  • Spot the threat of freelancers as a substitute

  • Reduce dependency on one large supplier (their tech partner)

  • Stand out by specialising in HR compliance for non-profits


Within 6 months, they repositioned their services, improved pricing structure, and signed 3 long-term retainers.


How to Apply Porter’s Five Forces in Your Business

  1. Block out an hour and brainstorm answers to each force with your team or advisor.

  2. Identify the biggest threat in your market—then choose one or two practical actions to address it.

  3. Repeat the analysis every 6–12 months as your industry evolves.

  4. Use it when expanding or pricing a new service—don’t make decisions in isolation.


Porter’s Five Forces is not just for big corporates. As a small business owner, it helps you think like a strategist, protect your margins, and build smarter—not just harder.
