GroupTrust Community Finance Platform

GroupTrust is a digital platform designed to replace paper registers, passbooks, and manual cash records for community-based finance groups, including Rotating Savings & Credit Associations (ROSCA), Joint Liability Groups (JLG), and Self Help Groups (SHG). It improves transparency, trust, and accountability for members, group secretaries, and NGO admins.
