01 Product overview

What the product does

ChamaConnect is a practical operations suite for chama groups that need clearer contribution workflows and traceable records. It combines role-based access, payment status tracking, member statements, and audit logs in a simple, mobile-friendly interface.

02 Problem and context

What it needed to solve

Many chamas rely on fragmented tracking across chats, spreadsheets, and manual records. This creates reconciliation delays, weak payment visibility, and low confidence in financial reporting.
