System Requirements Document for gilded-quick

1. Introduction

The purpose of this document is to outline the system requirements for the "gilded-quick" project. This project aims to develop a micro-SaaS solution specifically tailored for the quick commerce sector, focusing on real-time bin-level inventory synchronization and automatic SKU management. The solution addresses the unique challenges of quick commerce, such as perishable inventory management and last-mile delivery efficiency.

2. System Overview

The "gilded-quick" project is designed to provide a dedicated micro-SaaS platform for quick commerce operations, particularly those involving 10–15 minute grocery deliveries. The platform will offer tools to manage inventory at the bin level, ensuring real-time updates and automatic SKU management to prevent overselling and failed orders. The solution will cater to dark stores within a 2km delivery radius, with pricing tiers based on SKU count.

Key Features:

• Real-time bin-level inventory synchronization
• Automatic de-listing and relisting of SKUs based on stock levels
• Tiered pricing model ($99–499/month per dark store)

3. Functional Requirements as Story Points

• As a Store Manager, I should be able to view real-time inventory levels by bin to manage stock efficiently.
• As a Store Manager, I should be able to automatically de-list SKUs when stock reaches zero to prevent overselling.
• As a Store Manager, I should be able to automatically relist SKUs upon stock replenishment to ensure availability.
• As a Store Manager, I should be able to set up tiered pricing based on SKU count to optimize costs.
• As a Store Manager, I should be able to receive alerts for low-stock items to prevent stockouts.
• As a Store Manager, I should be able to generate reports on inventory turnover and dead-stock to optimize inventory management.

4. User Personas

• Store Manager: Responsible for managing inventory, ensuring product availability, and optimizing store operations.
• Warehouse Staff: Handles the physical management of inventory, including picking and restocking items.

5. Core User Flows

• Store Manager checks real-time inventory levels -> SKU automatically de-lists when stock is zero -> SKU automatically relists upon replenishment.
• Warehouse Staff picks items for delivery -> Inventory updates in real-time -> Store Manager receives low-stock alerts.

6. Visuals Colors and Theme

[Default — not specified by user]

• primary: #FF6F61 (a vibrant coral to represent urgency and freshness)
• primary_light: #FFA07A (a lighter coral for hover states)
• secondary: #4A90E2 (a calm blue to complement the primary color)
• accent: #FFD700 (a bright gold for call-to-action elements)
• highlight: #32CD32 (a lively green for notifications and active states)
• bg: #F5F5F5 (a light grey for the background)
• surface: #FFFFFF (white for card/panel backgrounds)
• text: #333333 (dark grey for primary text)
• text_muted: #777777 (medium grey for secondary text)
• border: #DDDDDD (light grey for borders)

7. Signature Design Concept

The homepage of "gilded-quick" will feature an interactive, dynamic inventory dashboard that visually represents the real-time status of inventory bins. Users can hover over bins to see detailed stock levels and interact with a 3D model of the store layout. This model will update in real-time as inventory changes occur, providing a vivid and engaging experience. The dashboard will use @react-three/fiber for 3D interactions and motion/react for smooth transitions and animations.

Landing Hero Motion Brief

The landing page will feature a continuous loop animation showing a quick commerce delivery process: a product is picked from a bin, travels through a dynamic route, and reaches the customer. This animation will be built using motion/react and CSS for a polished, responsive experience. The animation will highlight the efficiency and speed of the delivery process, with interactive elements allowing users to explore different stages of the journey.

8. Interaction Model & Motion Direction

• Intended Interaction Model: Animated
  • The landing page will feature moderate scroll-triggered reveals and hover transitions, with spring physics on interactive elements to enhance user engagement.
• Internal Pages: Static
  • Focus on layout clarity and minimal motion for dashboards and settings pages.

9. Non-Functional Requirements

• The system must handle real-time data updates with minimal latency.
• The platform should be scalable to support multiple dark stores simultaneously.
• Ensure data security and privacy compliance with relevant regulations.

10. Tech Stack

• Frontend: React for Web
• Backend: FastAPI
• Database: MySQL or MariaDB, using Alembic for migrations
• Local Orchestration: Docker, docker-compose
• Server-Side Orchestration: Kubernetes

11. Assumptions and Constraints

• The system will operate within a 2km delivery radius for each dark store.
• Pricing tiers will be based on SKU count, ranging from $99 to $499 per month.
• The platform must integrate with existing e-commerce systems for seamless operations.

12. Glossary

• SKU: Stock Keeping Unit, a unique identifier for each distinct product and service that can be purchased.
• Dark Store: A retail distribution center or fulfillment center that caters exclusively to online shopping.
• Bin-Level Inventory: Inventory management at the level of individual storage bins within a warehouse or store.
