# **Final Year Project Proposal & Software Requirements Specification (SRS)**
**Title:** *Small businesses can’t digitize sales* → **Software Solution: Web-Based POS + Inventory Management System**
---
## **1. Introduction**
### 1.1 Problem Statement
Small and medium-sized businesses (SMBs)—especially informal retailers, home-based sellers, and resellers like online buy-and-sell operators—struggle to digitize their operations. They rely heavily on manual processes such as:
- Physical notebooks for sales and inventory tracking,
- WhatsApp/phone for customer communication,
- Manual price markup calculation (e.g., 20% over cost price),
- Bank deposit confirmation for order validation,
- No centralized view of stock across multiple suppliers.
This leads to:
- Inaccurate stock records,
- Missed sales opportunities,
- Pricing inconsistencies,
- Time-consuming reconciliation,
- Poor customer experience due to lack of order tracking or notifications.
### 1.2 Proposed Solution
A **web-based Point-of-Sale (POS) and Inventory Management System** tailored for SMBs, especially online resellers and small retailers. The system will unify:
- Product catalog management (with multi-supplier sourcing),
- Automated markup pricing,
- Sales processing (including manual payment confirmation workflows),
- Real-time inventory tracking,
- Customer communication and notifications (SMS/WhatsApp/email),
- Order and delivery tracking.
Designed to be **low-cost, intuitive, and mobile-responsive**, enabling non-technical users to adopt digital sales practices without extensive training.
---
## **2. Objectives**
- Replace manual sales and inventory tracking with a unified digital platform.
- Automate pricing using configurable markup rules (e.g., 20% over cost).
- Support multi-supplier product sourcing with cost comparison.
- Enable order management from inquiry (via image upload) to delivery.
- Provide real-time stock visibility and low-stock alerts.
- Facilitate secure, auditable transaction records.
- Integrate simple customer notification systems.
- Ensure data integrity through a normalized, duplication-free database.
---
## **3. Scope**
### 3.1 In Scope
- Web application accessible via desktop and mobile browsers.
- User roles: Admin (owner) and Staff (optional).
- Product management: Add/edit products with images, cost price, selling price, supplier info.
- Supplier management: Track multiple suppliers per product with pricing history.
- Inventory tracking: Real-time stock levels, stock-in/out logs.
- Sales module: Create quotations, process sales, apply discounts.
- Order workflow: From customer inquiry (with photo upload) → quote → payment confirmation → fulfillment.
- Manual payment confirmation (e.g., bank deposit) with upload proof.
- Automated 20% markup (configurable) from cost to selling price.
- Customer database with contact info and order history.
- Basic reporting: Daily sales, top products, stock levels.
- Notification system: WhatsApp/SMS/email alerts for order status (pending, confirmed, shipped).
- Export data (CSV/PDF) for accounting or backup.
### 3.2 Out of Scope
- Native mobile apps (Android/iOS).
- Integrated payment gateways (e.g., Stripe, PayPal) – manual confirmation only.
- Advanced accounting (e.g., tax, balance sheets).
- AI/ML features (e.g., demand forecasting).
- Multi-branch or franchise support.
