Product Requirement Document (PRD) for Arisan Web App
1. Introduction
This document outlines the requirements for an Arisan Web Application, designed to streamline and manage traditional Indonesian arisan activities. The application will provide functionalities for managing a central cash fund, individual savings, member loans, and an automated winner draw system. The frontend will be built using Create React App (CRA), and the backend will leverage n8n for workflow automation and API management.

2. Goals and Objectives
Automate Arisan Processes: Reduce manual effort in managing arisan funds, savings, loans, and winner draws.

Increase Transparency: Provide clear visibility of all financial transactions and winner selections to all members.

Improve Accessibility: Enable members to access arisan information and perform actions from anywhere, anytime.

Enhance User Experience: Offer an intuitive and easy-to-use interface for all participants.

Ensure Data Accuracy: Minimize errors associated with manual record-keeping.

3. Target Audience
Arisan group organizers (administrators)

Individual arisan members

4. User Stories
