Covering WhatsApp when the person who usually answers is away: a rota, a written brief, and an agent that does not take leave

Most small businesses have one person who really knows the WhatsApp: the prices, the regulars, the tone. When that person is away, replies slow, answers get inconsistent, and a week later there is a backlog and a lost customer or two. The fix is to get what is in their head onto paper, and to let an agent hold the line.

Quick answer

Before anyone is away: write the knowledge brief (prices, policies, hours, the ten common answers) into the AI agent's knowledge base so it answers consistently regardless of who is on. Set a cover rota with fixed inbox check times. Give the cover person a one-page handover guide: how to take over, what to escalate, who to call. The agent answers the routine and books; the cover person handles the flagged chats. Tell customers nothing changes, because it does not.

Before the leave

Get it out of their head. Sit with the usual person for an hour and write the ten answers, the policies and the exceptions into the agent's knowledge base. This is the step that outlasts the leave. See writing the FAQ.
Check the agent handles the routine. Run the twenty-message test with the cover person watching.
Set the rota. Who owns the inbox each day, and the three fixed check times.
Write the one-page handover guide. How to take over (reply in the chat), what to escalate (complaints, refunds, anything medical or legal), who to call for what.
Point the handover email at the cover person for the period, in Settings.

During the leave

The agent answers questions, qualifies and books as usual; nothing changes for customers.
The cover person checks the inbox at the three times, replies to flagged chats from the transcript, and hands back when done.
Anything unusual gets a holding reply and a note for the usual person: "I'll have Mei come back to you on Monday about that."
The unanswered-questions list is left for the usual person to teach on return, unless the answer is obvious.

Public holidays and closures

The same setup covers holidays: the agent answers and books for the reopening, with closure dates in its knowledge and an away message on the number, per the closure templates. The difference is that nobody checks the inbox until reopening, so the agent's handover message should name the reopening date.

Mistakes that lose customers

Forwarding the business WhatsApp to the cover person's personal phone.
Letting the cover person improvise prices and policies.
No check times, so flagged chats sit for days.
Not telling the agent about the leave: a customer asking for "Mei" should be told she is back on Monday and offered help now.

Frequently asked questions

How do I keep WhatsApp answered when my receptionist is on leave?

Put their knowledge into the agent, set a cover rota with fixed check times, and give the cover person a one-page guide. The agent answers the routine; the cover person handles flagged chats.

Should the cover person use the business WhatsApp on their phone?

Use the shared inbox, not a personal phone. Replies are attributed and nothing leaves with them.

What should the cover person escalate?

Complaints, refunds, anything medical, legal or financial, and anything not in the knowledge base.

Does the agent cover public holidays?

Yes, answering and booking for the reopening with closure dates in its knowledge.

What is the long-term benefit?

The knowledge brief you wrote for the leave becomes the agent's permanent knowledge, so the business no longer depends on one person's memory.

An agent that does not take leave
