What enterprise buyers are actually deciding
In a large organisation the WhatsApp question almost never starts as a purchasing decision. It starts as a discovery: several teams are already messaging customers, usually through numbers nobody centrally approved, sometimes through an agency, often on handsets. The decision on the table is how to bring an existing, unmanaged channel under control without breaking what is working.
That reframing matters because it changes the evaluation criteria. You are not choosing the messaging product with the most features. You are choosing the one whose ownership model, consent handling, access control and audit trail can be described in a single document to people who will not be using it.
Asset ownership is the decision with the longest shadow
Who holds the Business Manager, who owns the numbers, who can submit templates and change display names. Get this wrong at the start and the company ends up dependent on an external party for a customer channel, which is a problem that surfaces at contract renewal rather than at implementation.
Consent is the question that arrives late and hurts
Nobody asks about opt-in evidence during a pilot. Everybody asks about it during an audit, a complaint or a regulatory query. Recording it structurally from the start costs nothing; reconstructing it afterwards is frequently impossible.
