On November 4th, Mercari launched a new delivery service called "Mercari Biz Delivery" for businesses that operate on its e-commerce platform, "Mercari Shops."
<New delivery service launched>

This service expands upon the features available to businesses that were not previously supported by "Rakuraku Mercari Delivery."
By integrating with Yamato Transport's "B2 Cloud" via API, it becomes possible to issue shipping labels in bulk, enabling smooth shipping of multiple orders.
In addition, it is possible to set shipping fees by region or charge shipping fees to the buyer, and it is also possible to set a flat rate nationwide for buyers.
Because the business name is listed as the sender, customers who purchase items from "Mercari Shops" can receive their products with greater peace of mind and security.
The pickup location is one of the locations registered when applying to use "Mercari Biz Delivery," or you can also bring your package to a Yamato Transport office.
All sizes, including refrigerated and frozen items, and Nekoposu (a specific shipping service) can be used for pickup. The delivery API will be made public in November.
