楽天RMS is a free business and productivity app developed by Rakuten Group Inc. for iPhone users. This app allows users to easily log in and access features such as sales tracking, inventory management, checking messages from Rakuten Marketplace, and quickly responding to customer inquiries.

One of the key features of the 楽天RMS app is the ability to log in easily, especially for compatible devices that support fingerprint or face recognition. Once logged in, users can view their sales data, including daily and monthly sales, conversion rates, average customer spending, as well as compare these figures with the previous month and year.

Another useful feature is the ability to reply to customer inquiries with the help of templates and images. If notification settings are enabled, users will receive notifications for new inquiries.

The app also allows users to check the latest order status and change orders to "楽天処理中" (Rakuten Processing) if no modifications are required.

Additionally, users can edit certain details of existing products and access the contact information of their assigned EC consultants directly through the app.

With 楽天RMS, managing your business on Rakuten Marketplace becomes more efficient and convenient, allowing you to stay on top of your sales, inventory, and customer communication.
