He played an important role in the Indian Davis cup team that reached the World Group from 1991-1998. He was part of the Indian Davis Cup team that reached the semifinals of the 1993 Davis Cup with wins against Switzerland and France, eventually losing to Australia. In singles, his major wins came against French duo of Arnaud Boetsch and Henri Leconte in Frejus, France in 1993, Wayne Ferreira in 1994, and Goran Ivanisevic in 1995 when India defeated Croatia, Jan Siemerink in 1995 to defeat Netherlands, and Jiri Novak in 1997.

Three weeks later he beat No. 25 Arnaud Boetsch on clay in straight sets in the Davis Cup. He also defeated Henri Leconte in the same week and even though Ramesh Krishnan closed the tie out by beating Rodolphe Gilbert in a five-setter, the architect of that victory was Paes.  In 1994, ranked No 143, he lost in the first round of a Challenger to No 208 Louis Gloria. Four weeks later, he beat World No. 13 Wayne Ferreira in straight sets in the Davis Cup.  In 1995, ranked No 130, he managed to beat Croatia's World No 7 Goran Ivanisevic (1992 and 1994 Wimbledon singles finalist) in a controversial five-setter on grass.
