Most programmes still split the book: a center register, a paper collection sheet, and an office spreadsheet that never quite matches. The overdue list is whoever remembered. That is fine until a review meeting asks which center slipped, and nobody can open one sheet and answer.
Microfinance LMS keeps members, loan cycles, and meeting-day collections on one account structure. A field officer sees who is due today and posts the collection before the group disperses. Portfolio at risk and overdue sit above the center, so a supervisor sees which routes need attention.
This is not a consumer instant-loan app. Individual branch loans belong in the Loan Management System. Unique interest, penalty, or group rules are custom software, not a bent product.
