Open a pet store

At present, more and more people like pets, and the market demand related to pets is slowly expanding. If you love pets and have some money, you may have been thinking about how to invest in opening a pet shop. The so-called preparedness, you might as well look at what you need to pay attention to when investing in pet shops. We interviewed Wang Pingxi, the chairman of Di Ku pet products chain store, and asked him to provide some experience of avoiding detours when investing.

Before investment: more or less

At present, there is still a great demand for pet shops in Beijing. If you invest, you can open the first store according to your own financial resources. If you are not very experienced, you can start from a small shop and grow bigger slowly.

The first store opened by Wang Pingxi is about 30 square meters. At that time, two people were invited to look after the store, and the initial investment (including rent, personnel, goods, etc.). ) About 654.38 million yuan, the store opened. If you want to invest in a 200-square-meter shop now, it will probably take 400,000 to 500,000 in the early stage.

Location is the most critical.

The pet industry is a new industry, which can't be compared with the traditional industry. So you should pay special attention when choosing the store site.

Customers who avoid pet shops in busy commercial areas are very special pets, such as cats and dogs, so it is best to avoid busy commercial areas as much as possible and not choose shops with high rent requirements. Because the country has corresponding laws and regulations, it is stipulated that pets are not allowed to enter the bustling business district; Secondly, the store mainly considers some people who are afraid of pets in society. They may be surprised to see a cat or a dog. So it is impolite for these people to open a pet shop in a busy business district. Owners who visit pet shops will definitely consider these and will deliberately avoid taking their pets to these prosperous areas, so opening a shop in a prosperous business district will affect business.

The reasons for choosing an open space to open a pet shop are as follows: first, pets can have enough activity space; Secondly, because pet parents bring pets, most of them come by car, and the open space can provide enough parking spaces.

The clerk must love pets.

The manager is the soul of a pet store. If you are not a manager, then the manager you choose to hire should love pets and be responsible. Wang Pingxi believes that opening a pet shop is like opening a nursery. Employees must treat the pets in the store as dumb children and carefully consider what they need. Every employee had better keep a pet at home.

Employees should undergo a period of training before taking up their posts. The contents of these trainings include: 1. Identify all kinds of pets. There are more than 0/00 kinds of dogs/kloc, and about 70 or 80 kinds of cats. It is also a basic condition that employees can identify the breed of pets. If one day a rare dog comes to the store, all employees can recognize it, which will further enhance the customer's sense of identity and intimacy with the store. Secondly, employees must know all kinds of information such as the efficiency and scope of application of the goods in the store, and they can put forward their own suggestions for different types of pets such as dogs and cats in the purchase of goods. In addition, employees need to be trained in some traditional business models, including some etiquette, polite expression, standing posture and sitting posture requirements.

The quality and style of goods should be guaranteed.

After the preliminary work is done, the products operated in the store should be comprehensive, and it is best to have domestic and foreign brands. If it is domestic procurement, we should choose some time-honored manufacturers with a long history, and sometimes we can entrust them to process and produce, so as to ensure the quality and style of the products. If it is a high-tech product, it is best to choose a foreign brand. However, when choosing imported goods, we must adhere to the principle that there should be no formal import procedures.

Retaining customers is the foundation of success.

Pet shop is also a service industry, which can be described as service first. Every employee is required to have the experience of keeping pets and can provide certain consulting services for customers in the store.

In addition, some promotion schemes can be launched every month to attract more customers. Membership system can be established at an appropriate time, and members can enjoy more feedback and appreciation services. You can organize outdoor pet trips several times a year to close the distance with customers.

Special preventive measures

1. Pay attention to the neighborhood. If you want to run a pet shop well, you must have a good relationship with your neighbors. The first thing to do at work is to clean up the pet droppings on the ground in front of the store. This is Wang Pingxi's experience.

2. Don't disturb people too much. I always feel that some people don't like pets such as cats and dogs. For the sake of these people, try not to disturb your shop too much.

3. Establish the reputation of the store. Pet shops rely on word of mouth, so it takes a certain process for operations to achieve results. Pet owners usually regard their pets as family members, so they usually spare no time and energy to go to good shops they trust. If you open a new store, you must build a good reputation if you want to attract customers. Generally speaking, 3 to 6 months is a normal period. If the store hasn't reached the ideal goal for more than 6 months, it is likely that there is something wrong with the operation.
