But i have a question, if your customer get your product, at the first time, how can they connect the Esp to wifi with your default SSID and Password?

Blynk has also Wi-Fi wizard for business. We call it Provisioning. In few clicks you can connect your device with your network from the app.

In the bottom of http://www.blynk.io/business/ you can find few screenshots.
