1, wallpaper material, specification, price, style, suitable for matching furniture colors. 2. The origin, brand, delivery date and construction precautions of wallpaper. 3. Suitable crowd, suitable age and suitable room type. The above three items are professional knowledge. Here are a few things you need to know from customers: generally, you should ask customers who have just entered the store a few questions, such as: decoration progress, decoration style, what flower pattern you like, whether it is full paste or background, and where is the house. The purpose of asking these questions is: first, we can judge whether customers choose spot or futures through the renovation progress, and we can also know whether customers can pay the bill today. Second, the decoration style is to bring you closer to your customers. With topics and professional persuasion, customers will trust you and rely on you, and at the same time increase the recognition of your recommended products. Third, what kind of flower pattern you like can give you a direction, and at the same time, you can recommend flower patterns to customers according to the decoration style. Of course, because you are not decorating in your own home, you still have to consult your customers. Whether it is full or not also determines the products you choose for your customers. Ask clearly, your goals and direction will be clearer, so the chances of being finalized by customers will be greater. Don't blindly recommend many times in sales, you won't be recognized by customers, and customers will greatly discount your professionalism. The size of five houses can let you know the customer's tolerance. For example, in some central areas of Shanghai, customers have strong psychological endurance, so when choosing products, price is particularly important. At the same time, we should also know the style, brand, color and price of some furniture, and we can know the customer's affordability through what brand of furniture or price customers buy. There is also professional knowledge, that is, the patterns or prices in the samples need to be memorized with some thoughts. Of course, everyone's understanding and description of flower patterns may be different, but there is basically no big difference in the same style. In fact, sales is a work whose details determine success or failure. If you carefully explore the information brought by customers, you will be able to make sales handy. Of course, sometimes selling is also a test of a person's mind and endurance, because different customers have different temperament and preferences, so your coping style is not the same. Invariance is not the principle of perseverance. You should learn to be flexible, which will save you some effort. I am a professional wallpaper maker. I hope my answer can help you!
