PH MultiCarrier Shipping Label

I am Kan Guo, and I have been running an e-commerce business for five years. I love your APP of Multi Carrier Shipping Label; it is really awesome. He is very close to our usage scenario. But after getting to know you these days, I would like to make the following comments to you in particular and hope to modify and upgrade your program to make it more powerful. --The adjustment suggestions for Shipping Lable are as follows
1. It is necessary to modify the name in ITEM in the APP. This is because the ITEM on the website is often used to promote website keywords, but when it is used for actual shipment, it is not recognized by the customs of some countries.
2. The unit price and total price of the product must be adjusted in the APP. The reason for this is very complicated, but trust me it is very necessary. If the price cannot be modified, your APP will not be able to be used. -- Regarding the total adjustment of the transportation of dangerous goods and ordinary goods.
I noticed that your APP could define the nature of each product, including whether it is a dangerous product or chemical, etc. However, this information was not used as the basis for the final calculation of freight. We need a comprehensive algorithm that can calculate load because some transportation companies do not accept the transportation of dangerous goods. For example, when two products A and B appear in the customer's shopping cart simultaneously, A is a product with a battery, and B is a standard product.
1. When A and B belong to the same warehouse, we usually combine A and B into one package and ship it. Therefore, the package should be carried by a company that allows the transportation of dangerous goods. Thus, the APP should present to the customer a freight quotation that enables the transport of hazardous goods company. And calculate the freight based on the combined weight of A and B.
2. When A and B do not belong to the same warehouse, the App should give a comprehensive freight quotation based on the shipping addresses of A and B. The combination of A's freight and the freight of B can be presented to the customer. When shipping simultaneously, it can split an order for two or more shipments and finally print two or more shipping labels of different shipping companies. --The logical improvement of the comprehensive calculation ability of the freight of the same order issued by different products.
From my point of view, there will be multiple calculation logic. I think users should be allowed to edit their differences based on their usage habits or differences in policies and laws of countries and regions. These are my summarize; I hope you can improve your App. Thank you for your reading. Sincerely & Regards
