In sales, you work hard to attract customers—yet sometimes, without even realising it, you can be doing things that push them away. It’s frustrating when prospects go cold or loyal customers suddenly stop buying, but often the cause isn’t mysterious. It comes down to small but costly sales mistakes that slowly erode trust and confidence.


At Business Coaches Sydney, we see this pattern regularly. Salespeople with good intentions unknowingly sabotage their chances because they haven’t been trained to spot and avoid these common pitfalls. The good news? Once you’re aware of the mistakes, you can change your approach and keep customers engaged.

Mistake #1: Talking More Than Listening

Salespeople often feel pressure to pitch quickly and cover all the details of their product or service. But when you dominate the conversation, you miss the chance to understand the customer’s real needs. Customers don’t want to feel “sold to”—they want to feel heard.


Instead, ask insightful questions and then listen actively. Tailor your responses to what matters most to the customer. Business Coaches Sydney emphasises this skill in Sales Training, teaching teams how to slow down, listen, and align solutions with customer priorities.

Under promise & over deliver

Mistake #2: Overpromising and Underdelivering

In the rush to close deals, some salespeople make promises they can’t keep. While this may win you the sale in the short term, it damages trust long-term. A disappointed customer is unlikely to return—and worse, they may share their negative experience with others.


Be realistic about what you can deliver. Set accurate expectations from the start and then exceed them wherever possible. Business Coaches Sydney helps sales teams build confidence in offering value without overselling.

Mistake #3: Ignoring the Follow-Up

A surprising number of sales are lost not because of price or competition, but because of poor follow-up. If you disappear after the first meeting or take too long to respond, customers feel unimportant and move on to someone more attentive.
Create a structured follow-up process. Whether it’s a thank-you email, a quick check-in call, or sharing a useful resource, consistent follow-up shows customers you care. Business Coaches Sydney encourages salespeople to treat follow-up as a core part of the sales cycle, not an optional extra.

Mistake #4: Focusing Only on Price

When salespeople lean too heavily on discounts or price comparisons, they signal that their product has no other value. This creates a race to the bottom where customers see you as interchangeable with competitors.
Shift the conversation to value. Highlight outcomes, service, and the unique ways you solve customer problems. Business Coaches Sydney trains sales teams to move beyond price and sell on the basis of value, differentiation, and trust.

Mistake #5: Neglecting Existing Customers

It’s easy to get caught up chasing new business and forget the customers you already have. But ignoring loyal clients is one of the fastest ways to drive them away. A neglected customer often feels unappreciated and will happily move to a competitor who gives them attention.


Show consistent appreciation to current clients. Keep them engaged with regular check-ins, updates, and added value. At Business Coaches Sydney, we encourage businesses to treat existing customers like VIPs—because keeping them is far more cost-effective than finding new ones.

Mistake #6: Not Adapting to the Customer’s Style

Every customer has a preferred way of communicating and making decisions. Some want the big picture, while others want every detail. If you fail to adapt, you create friction and frustration.
Pay attention to cues and adjust your style accordingly. Business Coaches Sydney often uses DISC profiling in training to help salespeople understand different personality types and communicate effectively with each.

Mistakes happen

Why These Mistakes Matter

Individually, these mistakes may seem small. But together, they create a customer experience that feels pushy, careless, or untrustworthy. Customers have more options than ever, and they won’t hesitate to walk away if they don’t feel valued.
The cost of losing a customer is high—not just in lost revenue, but in the time, money, and energy it takes to replace them. That’s why avoiding these mistakes is critical to building long-term success.

Sales success isn’t just about being persuasive; it’s about building trust, delivering value, and creating positive customer experiences at every stage. The mistakes outlined here are avoidable—but only if your sales team is trained to recognise and change them.


That’s where Business Coaches Sydney comes in. Their tailored Sales Training programs give your team the tools to engage customers effectively, avoid costly errors, and build relationships that last.
