The Customer’s Rigorous Product Selection Process

The collaboration started when a local enterprise that runs petroleum storage and transportation business needed to buy oil cleaners—they mainly used the products for cleaning oil stains on storage tank inner walls and transportation pipeline joints. To pick reliable products, the customer didn’t rush to make a decision; instead, they reached out to 10 suppliers at first, planning to screen step by step.

In the first round, the customer asked all suppliers to send basic product information, including usage scenarios, applicable oil stain types, and the dosage required for common cleaning tasks. We replied within 24 hours, not just listing the information clearly, but also adding practical tips like "how to save dosage without affecting cleaning results" based on common needs in petroleum storage and transportation. This detailed and down-to-earth introduction made us one of the 6 suppliers that moved on to the next round.

The second round was sample testing. The customer requested each remaining supplier to provide small samples, and they would test the cleaning effect under the same conditions—focusing on how quickly the product breaks down heavy oil stains and whether it leaves residues after cleaning. We sent the samples as required, and also included a simple user guide with the package, marking the best way to dilute the product and the recommended soaking time for different oil stains. The customer later mentioned that this small guide helped them operate more smoothly during the test.

The third round was price and supply capacity verification. The customer cared about two key points: whether the price was reasonable and whether we could deliver the goods on time when they needed large quantities. When the customer asked about the minimum order quantity and delivery cycle, we gave clear answers—no forced minimum order, and delivery within 3 working days for orders in the same region. For the price, we provided a transparent quotation list, explaining the price difference between different package sizes, so the customer could choose according to their actual needs. Unlike some suppliers who gave vague quotes, our straightforward approach made the customer feel more at ease.

The final round was a small-batch trial purchase. The customer decided to buy a small quantity first to use in their daily operations, to check if the product’s actual performance matched the sample, and if it was easy to use for their on-site staff. We arranged the delivery quickly, and when the customer contacted us to confirm the receipt and ask about simple usage precautions, we responded patiently and clearly, without pushing for more orders.

Winning the Cooperation Through Sincerity and Reliable Products

During the small-batch trial, the customer’s on-site staff found that the oil cleaner was easy to operate—no complicated preparation steps, and it worked well on the heavy oil stains that had been hard to clean before. They also noticed that the product didn’t cause any trouble during use, which met their basic requirements for practicality and convenience.

After using up the trial batch, the customer got in touch again. They said that after comparing all the suppliers, our product stood out in terms of cleaning effect and ease of use, and our responsive communication during the selection process also left a good impression. They didn’t have to chase for information or wait for a long time for replies, and every question was answered clearly and honestly.

In the end, the customer decided to place a formal order for a three-month supply. They told us: "We just need a reliable oil cleaner that works and is easy to use, and you’ve given us that. The whole process of choosing was smooth because you were straightforward and didn’t make things complicated." This simple cooperation was built on the reliability of the product and sincere communication, laying the foundation for potential repeat orders in the future.
