Channel strategy
Which support channel should get AI first?
How to choose between website chat, voice, WhatsApp Business, and Zalo OA for the first AI support rollout.
Use website chat when you need the fastest controlled launch
Website chat is usually the simplest place to start. You control the page, the agent entry point, the visible expectations, and the fallback to your team.
It also gives you quick evidence: which questions customers ask, where knowledge is missing, and when a person needs to step in.
Use voice when time-to-answer is the pain
Voice is useful when callers repeat the same questions, need basic triage, or want to leave a clear request. The goal is not to imitate a call center. The goal is to answer the common cases and capture the rest.
A voice rollout needs tighter language behavior and clearer fallback rules because mistakes feel more immediate than in chat.
Use WhatsApp or Zalo when the customer habit is already there
Messaging channels make sense when customers already use them for support. The advantage is convenience; the risk is that threads can mix sales, support, and account requests.
Start with knowledge-backed answers and request capture. Add channel-specific workflows only after the support boundary is working.
