How would you translate the sentences below:

Zapraszam Cie na kawę - I invite you for a coffee?

Dziękuję!

Answer

I invite questions: 
Zachęcam do zadawania pytań - I encourage you to ask questions. 
or 
Jestem otwarty na pytania - I'm open to questions. 
Translating invite as "zapraszam" in this case doesn't make sense.

Second one is ok :)
