In 1796, she appointed Numan ağa, the voyvoda of these districts, to act as her agent to collect the caizye and 'avariz dues from her çiftliks. In 1802, she appointed Al-Hac Hasan ağa as her kethüda when Hüseyn ağa, a former voyvoda, was too oppressive. She also appears to have received the malikane of the island of Andros and Syros in 1789. In 1801, she had a fountain built in her name in the Kuruçeşme neighbourhood of Istanbul. In 1804, she built another fountain in her name on the banks of Akıntıburnu.

Beyhan Sultan built a school in the vicinity of Yeşilioğlu Palace, opposite of Hatice Sultan Palace in the memory of her mother. The Beyhan Sultan Fountain, which is one of the most beautiful works of the Ottoman art of its kind in the Turkish era, was completely dismantled, but it has not been revived until today, in case of street expansion. The fountain, which was completely covered with marble, was seen to be dominant in the baroque style. The main façade was on the sea side and was processed in three sections with baroque arches, including milkstones. Although the Beyhan Sultan Fountain was created entirely under the influence of Western art, it was a monument that marked the location of a beach adorned this coast, apart from being a work that added beauty to the Bosphorus.
