Laser-Bot System Requirements Document

Introduction

This document outlines the system requirements for the "laser-bot" project, focusing on creating a basic version of an offline accounting application for iPhone, with plans for future upgrades.

System Overview

The laser-bot project aims to develop an iOS application for managing business transactions, including tracking goods received and payments made. The initial version will focus on core functionalities, with the potential for enhancements as the system evolves.

Functional Requirements

• As a Business Owner, I should be able to record incoming goods to track inventory.
• As a Business Owner, I should be able to record payments made to suppliers.
• As a Business Owner, I should be able to view a summary of all transactions.
• As a Business Owner, I should be able to filter transactions by date or party.
• As a Business Owner, I should be able to view outstanding balances.

User Personas

• Business Owner: Manages transactions, tracks inventory, and oversees financial summaries.

Core User Flows

• Business Owner records a new transaction -> Enters details of goods received or payment made -> Saves transaction -> Views updated summary.
• Business Owner filters transactions -> Selects date range or party -> Views filtered results.

Signature Design Concept

The homepage will feature an interactive ledger interface resembling a physical notebook. Users can "flip" through pages using swipe gestures, with each page representing a different transaction. The design will incorporate subtle animations using framer-motion to enhance the tactile experience, making the app feel like a dynamic, living document.

Interaction Model & Motion Direction

• Interaction Model: Animated
• The app will feature smooth transitions and hover effects to guide users through the transaction recording process. Each section will have a distinctive animation, such as a sliding panel for transaction details or a bouncing effect for notifications.

Non-Functional Requirements

• The application must function offline to ensure accessibility in areas with limited internet connectivity.
• The application should have a responsive design to accommodate different iPhone screen sizes.

Tech Stack

• Frontend: React Native for iOS
• Backend: Python with FastAPI
• Database: SQLite for local storage

Assumptions and Constraints

• The app will initially be developed for iOS only.
• Future upgrades will be based on user feedback and system performance.

Glossary
