At the request of Chavundaraya, Nemichandra wrote Gommatsāra in 10th century, taking the essence of all available works of the great Acharyas. Gommatasara provides a detailed summary of Digambara doctorine.
He wrote Trilokasara based on the Tiloya Panatti, Labdhisara, Kshapanasara, Pratishthapatha and Pratishthatilaka. Abhaya-chandra (c. 1325) wrote a vyakhyana on Nemichandra's Triloka-sara. Indra-vama-deva wrote Trilokya-dipaka based on Nemichandra's Trailokya-sara, for Nemi-deva of the Puravata (or Pragvata) family.
Earlier scholars believed that Dravya-sangraha was also written by him, however, new research reveals that this compendium was written by Acharya Nemichandra Siddhantideva who was contemporary to the Paramara king Bhoja.
