What Malaysian firms mean when they search for this
In Malaysia there is no argument to win about whether customers use WhatsApp. They do, and a great deal of the actual commercial agreement happens there rather than in any document. The question is why the business cannot see its own conversations. The thread sits on a salesperson handset, the manager has no view of it, and in a market where staff change employers frequently, that arrangement quietly exports your customer relationships every time someone resigns.
The written trail and the call are two halves of one deal
Most B2B deals here run the same way: the enquiry and the negotiation happen in the thread, then a phone call settles the price or the delivery date because that is faster than forty more messages. The practical consequence is that your written record and your voice record are in two different systems, and a tool that does not bring them onto one account leaves you with half a history.
