Tristock Inventory System

What is Tristock?

Products

1. Inventory & POS Platform

Tristock is a unified multi-shop management platform that orchestrates inventory, point-of-sale, HR, and finance operations for modern Ugandan businesses. It replaces disconnected spreadsheets and fragmented software with a single system that works across all shop locations in real time.

Features

• Responsive design with dark/light theme toggle
• Real-time inventory tracking across multiple shop branches
• Point-of-sale with MTN MoMo, Airtel Money, cash, bank transfer, and credit card support
• Low-stock alerts with configurable minimum stock levels
• Serial number, batch tracking, and expiry date management (FEFO logic)
• Sales orders, customer accounts, discounts, and professional invoicing
• HR module: employee clock-in/out, grace periods, late detection, and department management
• Payroll period generation and payslip management
• Expenses, budget tracking, and claim approval workflows
• Profit & Loss statements, real-time cash flow, and accounts receivable
• Excel and PDF export for reports
• Multi-branch centralized dashboard with branch-level permissions
• Full audit trails per cashier and shop

Powered by Next.js and TypeScript

User Workflow

1. Business owner signs up and configures shop locations and product catalog
2. Staff clock in via the HR module; permissions are assigned per role and branch
3. Cashier processes sales through the POS with mobile money or cash payment
4. Inventory levels update in real time; low-stock alerts trigger automatically
5. Manager reviews branch-level sales, expenses, and stock reports from the central dashboard
6. Finance team generates Profit & Loss statements and cash flow reports
7. Payroll is processed per period with auto-generated payslips

How it Works

1. Built with Next.js for server-side rendering and fast initial page loads
2. All data is managed through a PostgreSQL (Neon) database via Prisma ORM
3. Dynamic routes and server actions power each feature module end-to-end
4. Mobile money integration (MTN MoMo, Airtel Money) handles POS payments natively
5. Role-based access control enforces branch-level and feature-level permissions
6. Excel/PDF exports are generated server-side and streamed to the client

2. Admin Dashboard

The Admin Dashboard provides a centralized control panel for managing all shop operations, users, inventory, and financial data. It is the primary interface for business owners and managers overseeing multiple branches.

Open-Source and Modern Architecture

Tristock is built with modern web technologies and follows a strict layered architecture: Prisma schema → API routes → server actions → service layer → React Query hooks → Zod schemas → UI components. This separation of concerns ensures the codebase stays clean, testable, and easy to extend as new shop branches or feature modules are added. The platform is optimized for Ugandan business realities — UGX currency, local mobile money providers, and multi-branch operations.
