Sending goods on demo basis

But , whether it is possible to send the  goods merely on delivery challans. Because , If I send the goods on my GST Invoice , I have the doubt , customer will not raise his GST Invoice while sending these goods back to me ?

But, as confirmed with our tax consultant what he is saying is ,  first to send the goods on deliverychallans mentioning that , " goods are send for demo / approval basis ,  not for sale".  If the goods are retained by the customer , he will raise the po and we will send our final GST  Invoice to him giving reference of our earlier delivery  challan.

If the goods are returned , the same should be returned within 6 months . For returning these goods back to us , he will prepare his delivery challan and will send the goods to us. 

Pl. guide whether it is possible  under GST LAW ??
