Let’s be blunt! If you work for a small or medium-sized medical device company and you want to serve the entire market, there is something wrong with your sales strategy.
Let me explain. Expanding your market coverage to increase your sales is not a negative thing in itself.
However, it isn’t the most effective way to achieve sustainable and continuous growth. The true source of sales expansion lies in your existing customers.
Why It’s Important to Focus on Existing Customers
As highlighted by the Harvard Business Review, acquiring a new customer can cost 5 to 25 times more than retaining an existing one.
In the medical field, I’m absolutely convinced it’s far more expensive to win a new account—convincing a new doctor, securing a new tender—than it is to sell to existing customers.
Nurturing profitable customer relationships can:
- Increase sales
- Open new opportunities
- Strengthen customer loyalty
Especially if you’re not a major market player, customer retention and key account management are often more important than new customer acquisition.
“You will never reach your destination if you stop and throw stones at every dog that barks.”
Winston Churchill
This quote is a powerful reminder to stay focused. A confused, opportunistic, and unprioritized search for new customers can be a distraction—and even an obstacle—to growth.
Chasing every lead without a clear strategy drains time, resources, and focus. Without strong account management, pursuing new customers is like throwing stones at every barking dog.
So, let’s explore how you can grow your business by developing your existing customer base.
5 Ways to Increase Medical Sales with Existing Customers
1. Establish Strong Relationships

Having a solid, mutually respectful relationship with your profitable existing customers is one of the most important factors in gaining retention and loyalty.
There are many ways to build stronger relationships with your customers—basically, all related to creating extra value. The key point here is that different customers perceive value in different ways.
For example, some accounts value discounts more, while others prioritize better service, clinical support, or innovative solutions.
However, some elements work for almost all customers. Rapid responses to customer questions—whether via phone or email—are always welcome, as quick response times correlate with customer satisfaction and trust.
Provide value at every contact point. For example, each customer interaction with the sales force should be meaningful and valuable. Offering new data, new uses for existing products, or introducing specific benefits of the product tailored to the account is key to consolidating the relationship.
Stay informed of clinical and non-clinical changes. Monitoring updates and new trends can help you advise your customers on how potential changes could affect them, solidifying your position as a trusted partner.
Become a reliable source of information. When customers trust you as a source of insight, they are more likely to trust your products and do business with you.
2. Identify Customer Needs and Be Proactive

Each account or individual doctor has unique needs. When dealing with a doctor, it’s important to understand the “Job to Be Done” and their objectives when treating patients.
The sales force must be able to identify the specific needs of each individual doctor or account.
Asking the right questions and practicing active listening allows the sales force to identify and focus on customer priorities.
Being proactive doesn’t mean constantly pushing your product or service. Instead, it means emphasizing customer needs and suggesting appropriate solutions—even if they fall outside your product portfolio.
3. Identify Opportunities for Upselling and Cross-Selling

I’ve already addressed the controversial topic of upselling and cross-selling and the implications of these sales techniques.
I’m convinced that, if correctly implemented, these tactics can produce mutually beneficial relationships.
To identify existing customers with potential for upselling and cross-selling, the sales rep should develop a strong customer focus and maintain the customer’s perspective on their problems.
Practicing active listening and gaining a deep understanding of the customer’s business—and how it relates to your product portfolio—is the right way to identify potential for upselling and cross-selling.
4. Master Your Therapeutic Environment

To increase sales in current accounts, your sales force needs to become 360-degree experts in the therapeutic area.
Knowing your product and the major clinical aspects is not enough to become a true consultant. Today, the sales rep must be competent in any problem the customer might face in relation to the product—for example, reimbursement, funding, coding, procurement, delivery, supply, etc.
5. Correctly Identify the Potential of the Account

Not all customers are created equal. Some—your key accounts—are the most valuable to your company.
To identify the growth potential of your accounts, you should use some of the elements I previously described to select key accounts.
For example: customer outcomes, hard data like revenues, margins, and customer size; customer-supplier alignment (the degree of strategic convergence between your company and the customer); and customer characteristics like their attitude toward partnership.
The simplest way to determine whether a customer is high potential is by assessing these key aspects.
Conclusion
If you’re an SME aiming for sales success, look to your existing customers first—before chasing geographic expansion.
By delivering real value and focusing on customer needs, you can build loyalty and position yourself as a trusted partner. That’s the foundation for sustainable growth.
Exploring opportunities within your current accounts will help you:
- Drive long-term success
- Build a resilient business
- Achieve consistent sales development
