Hi, how are you. I have strong experience in Shopify Dropshipping, I purchase and deal with a lot of products everyday. There are a lot of SKUs, I use Google sheets to sort items out and fulfill the orders, I also have some IT knowledge, I can use Google Sheets formulas and code efficiently. If you give me an interview, I will show you some of my works.
I search around 3-5 good suppliers for a single product but only purchase from one supplier. I won't purchase from two suppliers because the same product from different supplier, their products may differ in color and size. When you sending the package, it will be a disaster.
About my negotiations techniques, I show the suppliers that I'm a big company and show them that I have many suppliers produce the same product. Then they will lower the price
