WhatsApp Business is an application built on top of the main release, that can be used to communicate in an efficient way with your customers. In case you have separate phone numbers for personal and business use, you can still use this app alongside the regular version on the same smartphone, by registering them with your different numbers. The cool thing is that you can even use a landline/fixed number when you're registering for the business account.
When the verification takes place, please remember to pick the "Call Me" option to obtain the required code. Inside the well-designed and organized graphical user interface, you have the ability of creating a profile for your business, and here you can provide information like contact details, official website and location. Even if it's a different version of WhatsApp, this one still provides regular features like the ability to chat, send multimedia files, create group chats, initiate calls, and more.
Another key element of this software is the ability to set-up quick replies for frequently asked questions. In addition, inside the interface you can use different labels to better tag and organize chats and contacts.
