[2] Comerciantes Unidos played its first season in the Peruvian Segunda División in the neighboring province of Santa Cruz due to their home stadium being remodeled.

During the 2015 season, Carlos Cortijo, who had won the Segunda División tournament the year before, was hired as the new manager by club president Aníbal Pedraza Aguilar.

Comerciantes Unidos was able to once again play its home matches at their local stadium, Estadio Juan Maldonado Gamarra.

Comerciantes Unidos had a great debut campaign in the 2016 Torneo Descentralizado where it finished 6th and qualified for the first time to an international tournament, the 2017 Copa Sudamericana.
