When the free app is enough
The WhatsApp Business app is free and does more than most owners use: a business profile, a catalogue, greeting and away messages, quick replies and labels. For a salon, a home kitchen or a small shop where the owner answers every chat, it's the right tool, and paying for a platform won't make those chats any better.
The app starts to hurt in predictable ways. The phone becomes the only place the business exists, so when the owner is busy, travelling or asleep, chats wait. Staff end up answering from the owner's phone, or from WhatsApp Web on a shared laptop, and nobody knows who told a customer what. Every reminder, confirmation and 'your order is ready' is typed by hand.
If none of that sounds familiar, stay on the app. We'd rather say so now than sell you a plan you cancel in three months.
