mossy-upi System Requirements Document

Introduction

The "mossy-upi" project is designed to provide a comprehensive UPI AutoPay subscription management solution tailored for businesses such as gyms, coaching centers, milk delivery services, SaaS, and membership-based organizations in India. The primary focus is on facilitating efficient payment collection, retries, reminders, and reconciliation processes.

System Overview

The mossy-upi system aims to streamline the recurring payment collection process for businesses that rely on UPI AutoPay. By addressing the operational challenges associated with subscription management, the system will enhance the efficiency and reliability of payment transactions.

Functional Requirements as Story Points

• As a Gym Owner, I should be able to set up UPI AutoPay for recurring membership fees.
• As a SaaS Provider, I should be able to automate payment retries for failed transactions.
• As a Business Owner, I should be able to send payment reminders to customers before due dates.
• As a Milk Delivery Service, I should be able to reconcile payments received with outstanding invoices.
• As a Coaching Center Manager, I should be able to view detailed reports of payment collections and failures.
• As a Membership Business Owner, I should be able to manage customer subscriptions and payment schedules.

User Personas

• Gym Owner: Manages gym memberships and requires efficient payment collection.
• SaaS Provider: Offers software services on a subscription basis and needs automated payment management.
• Business Owner: Operates various membership-based services and seeks streamlined payment processes.
• Milk Delivery Service: Provides daily delivery services and requires regular payment reconciliation.
• Coaching Center Manager: Oversees educational services and needs detailed financial reporting.

Core User Flows

• Gym Owner sets up UPI AutoPay -> Members enroll -> Payments are collected automatically -> Failed payments trigger retries -> Payment reminders are sent -> Reconciliation of payments.
• SaaS Provider configures subscription plans -> Customers subscribe -> Automated payment retries for failed transactions -> Payment reminders sent -> Detailed reports generated.
• Milk Delivery Service sets up payment schedules -> Customers are billed -> Payments are reconciled with invoices -> Reports are generated for financial tracking.

Signature Design Concept

The mossy-upi landing page will feature an interactive "Subscription Flow Journey" animation. Users will see a dynamic illustration of a payment journey, starting from subscription initiation to successful payment completion. As users scroll, they will witness animated icons representing each step: subscription setup, payment processing, retries, reminders, and reconciliation. Each icon will animate into the next, creating a seamless flow. The animation will be built using motion/react for smooth transitions and interactivity.

Landing Hero Motion Brief

The hero section will depict a digital landscape where subscription icons (e.g., gym weights, software disks, milk bottles) gather around a central UPI logo. As the UPI logo pulses, lines representing payment flows connect the icons, transforming them into a unified subscription management dashboard. This animation will loop every 10 seconds, with interactive elements allowing users to hover over icons for more information. The animation will be responsive and maintain clarity in reduced-motion settings.

Interaction Model & Motion Direction

• Intended Interaction Model: Animated
• The landing page will feature moderate scroll-triggered reveals and hover transitions, enhancing user engagement without overwhelming them. Interactive elements will have spring physics for a polished feel.

Non-Functional Requirements

• The system must ensure secure handling of payment data in compliance with local regulations.
• The platform should support high availability to handle peak transaction loads.
• User interfaces must be responsive and accessible across devices.

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

Assumptions and Constraints

• The system assumes users have access to UPI-enabled bank accounts.
• Constraints include compliance with Indian financial regulations and UPI standards.

Glossary

• UPI: Unified Payments Interface, a real-time payment system in India.
• AutoPay: Automated payment processing for recurring transactions.
• Reconciliation: The process of matching payments received with invoices issued.
• Retries: Automatic attempts to process failed payments again.
• SaaS: Software as a Service, a software distribution model.
