About karoso

Karoso was born out of frustration. As our own eBay business grew, answering messages became so time-consuming that went hunting for a solution. We tried out third-party messaging solutions and finding deficiencies in them all, we became determined to create a better solution.

Avoid multiple browser tabs, waiting for messages to load, or flicking back and forth between pages on eBay. Access all your eBay messages in Karoso in convenient SMS format, threaded and grouped by customer, and with easy access to transaction status, return requests and buyer cases. Effortlessly view a customer’s full communications history, create templates for common replies and manage your eBay customers with confidence and efficiency. Whether you have dedicated customer support staff or run an eBay business on your own, Karoso can save you time and streamline communications with your eBay customers, allowing you to focus on delivering a better customer experience all round.
