Can you please update me today about Indenting Business?

One of my colleagues resigned his job two years back. He was working in our company as Business Correspondent Officer. His main duties were to contact the suppliers by phone, fax, e-mail & import different items like stationery, machine, bicycle parts vehicles etc in favour of our company. He was very needy and draw salary same as me US$1500 per month.Some days ago we saw him in an International fair & he informed me that he has been doing business that is he has his own INDENTING FIRM & earning a lot of money. Actually I want to know the type of this Indenting business. Can you please update?
