I am working in private pharmacy , how can I increase my incoming ?

Salam, if by incomming you mean sale then inorder to increase your sale you should inhabce your services and offer best prices. Being a pharmacist you should try patient counseling about their deseases and adherance to the therapy. If you provide better counseling that the patients understand their medicines they will deffinetly return to you for the next refill of their prescription. BEST OF LUCK
