Overview
A modern cross-platform debt management system designed for grocery stores and small businesses. It helps shop owners manage customer debts, track purchases and payments, monitor due dates, and communicate with customers through WhatsApp.
The problem
Many small grocery stores and local businesses still rely on traditional paper notebooks to record customer debts. This makes it difficult to track outstanding balances, remember payment deadlines, manage partial payments, and follow up with customers who are late.
Concept and solution
Debt Notebook provides a centralized digital solution for managing customer debts across web and mobile devices. Shop owners can register customers, record purchased items and amounts, set payment deadlines, track collections, and monitor overdue accounts. The platform also supports WhatsApp-based customer communication and reminder workflows.
Design and development
The system is designed around a simple debt management workflow. Shop owners register customers using their names and phone numbers, create debt records containing purchased items, amounts, and transaction dates, and specify payment deadlines. The dashboard organizes outstanding debts and payment history, identifies overdue accounts, and provides notification and WhatsApp communication features to help owners follow up with customers.
