Source: All Business – Every salesperson, regardless of the industry, product, or skill level, makes mistakes. Here are some basic sales mistakes to avoid and some tips for selling more and having happier customers.
1.     Not listening: Listen to your customers, identify the need, and fill it.
2.    Overselling: Know when to stop selling.
3.    Being unprepared: If you are prospecting for new business, know what you are going to say and be ready for questions you may be asked.
4.    Jumping straight to the sale: Do not rush to the sale. Take the time to educate your customers, and they will reward you with sales.
5.     Not closing the sale: It may seem unnecessary, but sometimes asking for the sale can be the nudge your customer needs to make a final decision.
6.     Going off topic: If the sale is the topic, don’t veer too far off on tangents.
7.     Not researching your customer: Get to know who makes up your target audience.
8.     Judging books by their covers: Do not let race, creed, gender, ethnicity, or appearance stand in the way of making a sale.
9.     Not following up on leads: Follow-up is a critical aspect of sales that is often neglected.
10.   Failing to prospect for new customers: Even when sales are at their peak, you need to devote time to looking for more customers. No company can survive without a constant influx of new customers, so no business can afford not to prospect for them.
