Feature Completeness Check
Ensure all basic functions of the customer service system are fully operational, including instant messaging, auto-replies, human handoff, agent workspace, visitor queuing, and message history. It's recommended to test each feature based on business scenarios, such as simulating visitor inquiries, testing agent assignment and responses, and verifying auto-reply effectiveness. Pay special attention to cross-department collaboration scenarios, such as smooth transfers and proper workflow of tickets.
Data Migration and Synchronization
If migrating from an old system, check that historical customer data, chat records, and service tickets are fully imported. Verify key fields like customer names, contact details, issue categories, and resolution outcomes to avoid data corruption or loss. Also, ensure interfaces with existing CRM, order management, and membership systems are functioning correctly for real-time data synchronization.

Security and Permission Settings
Before launch, configure user permissions to differentiate roles such as administrators, agents, and quality inspectors to prevent unauthorized access. Check for encrypted data transmission (HTTPS), chat log storage, and access restrictions. For cloud-based systems, confirm the provider's compliance certifications and data backup policies. It's advisable to conduct at least one penetration test to identify common vulnerabilities.
Channel Integration and Testing
Customer service systems typically need to connect with multiple channels like websites, WeChat Official Accounts, mini-programs, and apps. Perform end-to-end testing for each channel: from visitor inquiries to agent reception and response, then back to the visitor to confirm message delivery. Pay attention to display format differences across channels, such as text, emojis, images, and links. Test concurrent load during peak hours to ensure the server can handle expected traffic.
Team Training and Drills
Organize training sessions for customer service staff before launch, covering basic usage, common issue handling, transfer procedures, and ticket creation. Conduct simulated launch drills to help the team familiarize themselves with the new interface and interaction logic. Collect feedback after training to adjust workflows or quick reply templates as needed. Ensure key personnel are proficient in backend management functions like monitoring, statistics, and reporting.

Contingency Plans and Rollback Strategy
Establish a problem response mechanism for launch day, defining responsible persons, feedback channels, and handling procedures. Prepare a rollback plan to quickly switch back to the old system or a backup solution in case of severe failures. Back up old system data in advance and maintain a parallel operation period of at least one week to compare data consistency. It's recommended to launch during off-peak hours to allow the team buffer time.
Frequently Asked Questions
Will chat records be lost after launch?
Should we keep the old system for a while?

Next Steps
After completing the above checks, consider a phased launch by first opening to a subset of users or during specific times for observation, then switch fully once confirmed stable. Continuously monitor system logs, customer feedback, and agent experiences during the first week after launch, promptly fixing any anomalies. Regularly review permissions, update knowledge bases, and optimize auto-reply rules to ensure the customer service system provides stable support for your marketing site.
