WhatsApp Business on one phone does not survive a second closer.
The app is built for one person. A team needs the API, and the API brings rules most people discover the day a message is silently rejected: a 24 hour window, template approval, and categories that change what you are allowed to send.
A real shared inbox
Several closers on the same number, with who answers what, instead of a phone passed around.
The 24 hour window, respected
Inside the window, free text. Outside, an approved template or nothing. The setter never pretends it can send.
Templates that get approved
Categories, variables and examples handled before submission, because a rejection costs days.
One contact across channels
The same prospect writing on Instagram then WhatsApp is one contact, not two half conversations.
What a two closer team looks like
Assumed figures, not client results. Replace them with yours.
Closers on the number
Conversations per day
Answered under 5 minutes
Reply time before
Speed to lead is the cheapest lever on this channel: the first answer decides whether the second one is even read.
How it runs
Connect the number
WhatsApp Business API through the official Meta path, no unofficial bridge.
Write the script and the templates
One script for the conversation, templates for what happens after the window closes.
Turn the AI on
Off by default. Nothing goes out before a human switches it on.
Watch the window
Every conversation shows how long the free window has left, so nobody wonders why a message did not go.

FAQ
Can two closers use the same number? +
Yes, through the WhatsApp Business API. The consumer app is limited to one main device plus linked devices, which is not the same thing as a shared inbox several people can work from.
What is the 24 hour window? +
After a prospect writes to you, you can answer freely for 24 hours. After that, only an approved template can reopen the conversation.
Do I need Meta approval? +
Yes for the API and for each template. The categories matter: a marketing template and a utility template do not follow the same rules.
What if a template is rejected? +
You fix the wording and resubmit. That is precisely why the templates are written before you need them, not the day of the campaign.
