Unistore – Advanced Omnichannel E-commerce & POS SaaS
How it Works
U
nistore is an all-in-one omnichannel retail platform that bridges the gap between online e-commerce stores and physical brick-and-mortar brick-and-mortar operations. It features a fully integrated, real-time Point of Sale (POS) system that allows physical retail cashiers to process in-store checkouts seamlessly while sharing a single, unified inventory database with the digital storefront. Unistore centralizes multi-channel product management, dynamic pricing, customer loyalty tracking, instant digital receipt generation, and global billing into a unified dashboard, enabling retail businesses to scale their operations smoothly across all sales channels.
Key Features
- Integrated POS Terminal: A high-speed, barcode-scanner-compatible Point of Sale interface designed for fast physical checkouts, custom discounts, and split payment processing.
- Omnichannel Inventory Sync: Real-time automated stock synchronization between the online store and physical retail locations to completely prevent overselling.
- Automated Billing & QR Receipts: Generates instant digital PDF invoices using mPDF and embeds secure tracking codes with PHP-QRCode for effortless physical receipt scanning.
- Multi-Gateway Global Payments: Accepts secure, international, and localized retail payments through integrated processing via PayPal, Billplz, and Midtrans.
- Product & Variant Matrix: Comprehensive management of multi-attribute products (size, color, SKU) supported by interactive, server-side DataTables.

nwidart/laravel-modules, enforcing a highly structured, scalable modular architecture that separates domain logic into self-contained, reusable modules. - Relational Schema & Robust ORM Management: Designed an optimized MySQL database utilizing Laravel Migrations and Eloquent ORM to handle complex relational data models, using Faker and PHPUnit to execute automated testing suites.
- Enterprise Role & Security Protocols: Integrated
spatie/laravel-permissionto enforce precise, granular Role-Based Access Control (RBAC), alongsidelaravel/sanctumfor stateless API authentication and Google reCAPTCHA v3 for bot protection. - 10+ Multi-Gateway Payment Orchestration: Developed a unified, decoupled payment processing layer supporting international and regional gateways, including PayPal, Stripe, Razorpay, Paytm, IyZico, Mollie, MercadoPago, Midtrans, Paystack, Duitku, and YooMoney.

- Iterative Stress Testing: Executed aggressive automated race-condition simulations to ensure the database remained accurate when a product was sold on the website and at the POS terminal at the exact same moment.
- Seamless System Deployment: Built and integrated custom utility modules including mPDF for structured invoice printing and Monolog for auditing financial transactions.
- Business Growth Outcomes: Delivered an advanced retail ecosystem that slashes manual ledger reconciling, cuts down customer waiting time at physical counters, and drives omni-channel operational efficiency.
