In the digital era, instant messaging tools have increasingly significant impacts on both work and life. While both WeCom and WeChat belong to Tencent, they have distinct functional positions. WeCom is dedicated to providing enterprises with an efficient and secure communication and collaboration platform, whereas WeChat caters more to personal social needs. Therefore, it is not recommended for employees to use personal WeChat for client communication, as it may expose them to information security risks, distractions from social information, and potential damage to corporate image.

Moreover, the transfer of client resources upon employee turnover poses a significant challenge. Customer resources stored in personal WeChat accounts are often difficult to smoothly transition, potentially leading to the loss of important clients for the enterprise. On the other hand, WeCom facilitates the seamless transfer of client resources through its organizational structure and collaboration features. Enterprises can leverage WeCom management capabilities to ensure that upon an employee's departure, client resources are smoothly transferred to the new recipient, thus maintaining corporate client relationships and business continuity.

For foreign enterprises, using WeCom when receiving Chinese clients not only avoids the limitations of adding contacts on personal WeChat, ensuring smooth and efficient communication, but also better manages and transfers client resources, ensuring stable business development.

In summary, to ensure efficient work communication, information security, corporate image, and stable transfer of client resources, WeCom is recommended as the preferred communication tool for businesses with their clients.
