A good salesperson is not measured by how much they sell today, but by how many problems they solve for their customers. Because trust is not built through one transaction — it is built through years
The Moment a Customer Reported a Problem, I Learned What True Sales Means
Yesterday, I asked my customer, “Is there anything that will be ordered soon?”
This morning, he replied, “There are 4 more bad modules, 8500 nits.”
At that moment, my heart sank. My first thought was to ask him when these modules were shipped. But then I stopped myself because there was a serial number label on each module, and I believed we should already be able to identify the production date from it. So I simply replied:
“Hi Jack, we will check it.”
After checking the serial number, I found that these modules were produced on July 4th, 2025 — almost exactly one year ago. Out of 100 modules, 4 had failed. Naturally, the customer was very disappointed.
I immediately communicated with our engineering team to investigate the root cause. Finally, we discovered that the problem was not related to the LEDs themselves. The issue was caused by poor heat dissipation from the IC because the back glue was applied too thickly. The thick layer of glue affected the heat release and shortened the product lifespan.
After identifying this issue, we made improvements. Starting this year, we have changed our waterproofing process from back-glue filling to spray coating, which provides better heat dissipation and helps extend the product lifetime.
Today, I shared this explanation and improvement plan with my customer.
This experience reminded me that being a good salesperson is not just about selling products. A good salesperson should always stand behind the customer, solve problems, and continuously improve. When customers face problems, what they need is not only an answer — they need someone they can trust.
A good salesperson is not measured by how much they sell today, but by how many problems they solve for their customers. Because trust is not built through one transaction — it is built through years of support and commitment.
