The management account login template is used to collect basic information parameters of various door and window sales personnel, while the customer account login template is used to collect basic parameter information of customers;

[0014] Multiple role names are set in the management account login template, and the role names are divided according to the job level. The corresponding permission options are determined according to the role responsibilities, and the higher the job level, the more permission options are determined;

[0015] And after the customer logs in to his account, it is used to exchange information with the door and window sales staff.

[0016] Preferably, the operation of extracting customer information by the customer management module is:

[0017] Extract the installation address of the customer's doors and windows based on the customer's login information, match the required installation address with the sales address of each store, and arrange for the corresponding sales store or salesperson to receive the customer;

[0018] Then, based on the customer's door and window needs, the corresponding salesperson account is matched for inquiry and interactive operations.

[0019] Preferably, the operation of determining the measurement order in the sales management module using the order management module according to the instruction of the customer management module is:

[0020] When the customer clicks on the measurement reservation, a measurement instruction is generated and transmitted to the customer management module, forming a measurement order and related fee contract. After the customer pays the measurement fee for the measurement order, the measurement order is confirmed and arranged;

[0021] Based on the specific location of the measurement order, the location of the door and window measurement personnel is determined, and after matching, the measurement personnel closest to the specific location of the measurement order are determined. The measurement order is transmitted to the measurement personnel for processing in the customer management module.

[0022] Preferably, the order confirmation model is established by:

[0023] The surveyors collect image data on site and transmit it to the customer management module. The basic model of the order confirmation model is established with the coordinate axis. The horizontal distance under the image data is used as the horizontal axis coordinate, and the vertical distance under the image data is used as the vertical axis coordinate.

[0024] Then, based on the data collected on site, the corresponding corner points of the door and window features to be installed are determined, and the coordinate axis is introduced according to the coordinates of the corresponding corner points to obtain the order confirmation model. Subsequently, the product is determined and matched with the order confirmation model to form the door and window product rendering.

[0091] Sort by priority value, and the lower the priority value, the more product data is recommended.

[0092] The data interaction between customers and sales management is completed through the question-and-answer module, and the key features in the interactive data are extracted through the search function. The key features are then matched with the product data in the product management module, and the priority values ​​of each product data are obtained in combination with the sales situation and price situation. The products are sorted and recommended to the customer viewing interface through the priority value. The system can collect and analyze a large amount of sales data and customer information, avoiding blind selection by customers, and can better adapt to customer selection and recommend the required products, thereby improving the convenience of sales management.

[0093] In the embodiment of the present invention, the sales management module generates detailed order data and implements the prepayment operation as follows:

[0094] After the customer selects the corresponding door and window product, the door and window product information is introduced based on the order confirmation model to generate the door and window product renderings;

[0095] After the customer confirms the renderings of the doors and windows products, a formal order and order contract will be generated, and after the customer confirms the formal order, the order contract will be signed;

[0096] Then the formal order will be arranged after the advance payment is paid.

[0097] The present invention also discloses an Internet-based door and window sales management method, which specifically includes the following steps:
