How to track sales follow-ups on WhatsApp

To track sales follow-ups on WhatsApp, watch 4 things on your company numbers: customers waiting past your reply SLA, promises reps made and have not kept, deals with no message in either direction for days, and missed calls nobody returned. None of them needs a task in a CRM; each can be read from the conversations themselves.
Most advice on WhatsApp follow-up is about the message: when to send it, what template to use, whether to automate it. That assumes the manager already knows which follow-ups are due. On a team that sells from the WhatsApp Business app on company phones, nobody does. The follow-ups live in 12 phones, and the only list of them is in each rep’s head.
A CRM task list is the usual answer, and it only knows about the follow-ups a rep remembered to log. The ones that slip are exactly the ones nobody logged. So this is the other approach: read the follow-ups out of the conversations, where they already are.
1. The customer is waiting
The simplest follow-up is a reply. A customer asked something and has heard nothing. Set a reply SLA in working hours, and every customer past it is a follow-up that is due, listed by name with the rep against it. How to measure a WhatsApp response SLA covers doing that fairly; SLA tracking is the screen.
2. The rep promised something
“I’ll send you the quote tomorrow.” “Let me check with the warehouse and come back to you.” These are the follow-ups that lose deals, because the customer is not waiting on a reply. They got one. They are waiting on the thing the reply promised: what your rep promised the customer covers the ones that cost money.
2 ways to catch them. A deadline rule states the promise as an SLA: when the rep says “I will send” or “quote”, something with a figure or a PDF follows within 24 hours, and the rule reports how often that happens on time. And on every plan, Nora, the AI that watches your queue, reads your customers’ threads and lists promises that are due or overdue, each quoting the message where it was made.
3. The deal went quiet
A conversation that was busy 2 weeks ago and has had no message in either direction since. Nobody is late, so no inbox flags it. The customer did not follow up and neither did the rep, and the deal is drifting to whoever did. Coverage lists these by how long they have been quiet, which is the list to hand a rep on a Monday.
4. The customer rang and nobody rang back
A missed WhatsApp call with no call back and no message since. There is no text to be late on, so a messaging-only view never shows it. Call tracking logs every call on the company number and lists the unreturned ones by customer. It never records the audio.
What not to track as follow-up
Messages sent. A rep who sends 30 check-ins that say nothing has followed up 30 times and moved nothing. Follow-up is a customer who was owed something and got it, and the 4 lists above are built on that, not on volume.
Doing it without a new tool for reps
Each of these comes from the conversations on the company numbers, so the reps do not change anything. They keep the WhatsApp Business app on their company phones; each number is linked once by QR code, the same way WhatsApp Web is. Nothing is sent on their behalf, ever. The follow-up still comes from the rep; the manager just knows which ones are due. Tell the team what is measured before you start; what your employer can and cannot see is written for them.
