System Requirements Document for whatsapp-xplore

1. Introduction

The whatsapp-xplore project aims to develop a micro-SaaS application focused on WhatsApp lead follow-up and recovery for small businesses. This product is designed to help businesses such as real-estate agents, tuition centres, clinics, salons, automobile dealers, and wedding vendors manage their WhatsApp enquiries more effectively. By automating lead categorization, follow-ups, and providing AI-generated replies, the application seeks to bridge the gap between awareness and adoption of AI automation among Indian SMEs.

2. System Overview

The whatsapp-xplore application is a SaaS product that automates the process of managing WhatsApp leads for small businesses. It captures enquiries, categorizes leads, generates AI replies, and schedules follow-ups. The system also includes features like hot lead detection, a missed-lead dashboard, WhatsApp templates, and conversion tracking. The product is designed for small-business lead managers who need to efficiently convert enquiries into customers.

2a. Product Interpretation and Delivery Boundary

The application is delivered as a SaaS product with a focus on small businesses. It requires a WhatsApp provider connection for capturing enquiries and performing outbound follow-ups. The system includes background automation for scheduled follow-ups and hot-lead detection. The application owns the identity and session continuity for managing lead records, follow-ups, templates, and conversions. The product is exploratory and remains a basic fallback due to the user's confirmation of interest without selecting a specific idea, audience, or feature scope explicitly.
