With a WhatsApp business profile, you will be instantly classified as a business account. These come with your company profile for branding, as opposed to typical private accounts.
WhatsApp will allow clients to view your business name and logo at the top of the chat, even if they haven't saved you as a contact. Which is great for brand awareness.
If your WhatsApp profile is clicked on, all the information will be given at just a single glance. This includes Picture cover, description, email address, website, business hours, and more. This ties your WhatsApp profile to your brand, describes your service on this channel, and provides alternative channels for people to approach and learn more.
