The Student Information Management System (SIMS) business plan aims to enhance communication between parents and schools by providing online access to children's performance, attendance, and school activities. The software addresses the needs of working parents by offering timely updates and reports, while also filling a gap in the market for improved school-to-home communication. Revenue forecasts indicate significant growth potential over three years, supported by setup fees, monthly charges, and a gain-sharing model with schools and resellers.
