POS Application Enhancement – Payment Gateway & Distributor Module (PHP / MySQL) Project Overview We are developing a custom POS (Point of Sale) application using PHP and MySQL. The system was earlier built with a subscription-based (SaaS) payment module, which has now been removed as the application is no longer SaaS-based. We are looking for an experienced developer to: Integrate a direct payment gateway into the POS checkout flow Add a Distributor module for stock and order management between the parent company and franchise stores Key Requirements 1. Payment Gateway Integration - Integrate a payment gateway at the product sale level (POS checkout). - The existing subscription-based payment module has already been removed. - Add an option to select payment mode during checkout (e.g., Cash, Card, Online Gateway). - Ensure proper transaction handling and validation within the POS workflow. - Maintain security and performance best practices. 2. Business Structure - One Parent Company - Multiple Franchise Stores under the parent company - Centralized POS system with role-based access 3. Distributor Login & Stock Management - Develop a Distributor module responsible for managing product stock for franchise stores. - Stock Workflow – Two Scenarios * Scenario 1: Franchise-Initiated Order - Franchise owner places a stock order. - Distributor reviews and approves the order. - Upon approval, stock is automatically updated for the franchise. * Scenario 2: Distributor-Initiated Invoice - Distributor creates an invoice/order for a franchise. - Franchise owner approves the invoice. - Stock is applied only after approval. 4. Role-Based Access (Enhancement Only) - A role-based access system already exists. - Introduce one new role: Distributor. - Implement login and dashboard access for the Distributor role. - Configure permissions specific to distributors, primarily: - Stock management - Order approval - Invoice creation and coordination with franchise owners - Existing roles (Parent Company Admin & Franchise Owner) remain unchanged, except where interaction with the Distributor role is required. 5. Technical Stack - Backend: PHP - Database: MySQL - Existing POS system (codebase already available) - Payment gateway integration experience is required 6. Expected Skills - Strong experience in PHP & MySQL - Prior experience with payment gateway integration - Experience with POS, inventory, or ERP systems - Understanding of role-based access control - Ability to write clean, scalable, and secure code 7.

Hey — saw your post about enhancing your PHP/MySQL POS with a payment gateway and a new Distributor module. The tricky part here is keeping the stock flows and role-based access clean while you bolt on payments at the sale level, without breaking what already works for Parent and Franchise roles. Quick question before I suggest an approach: Which payment gateway are you planning to use (Stripe, Razorpay, PayPal, local bank API, etc.), and does it need to support split logic per franchise, or just a single merchant account on the parent company? I’ve worked on PHP/MySQL POS and inventory systems with role-based access and online payment integrations, including approval-based stock workflows between central and franchise locations. If you can share your current codebase structure (or Git repo access) and any existing DB schema or flow diagrams, I can review and tell you exactly how I’d plug in the gateway and distributor workflows within your current architecture.

Hello, I’m a PHP & MySQL developer with hands-on experience in POS systems, inventory management, and payment gateway integrations. I’ve worked on enhancing existing codebases, especially migrating systems away from SaaS models to direct, on-premise payment and role-based workflows. For your POS enhancement, I can: Integrate a direct payment gateway into the POS checkout flow with proper transaction validation. Add payment mode selection at checkout (Cash, Card, Online Gateway). Ensure secure and reliable payment handling following best practices. Design and implement the Distributor role within your existing role-based access system. Build the complete Distributor–Franchise stock workflows, covering both: Franchise-initiated stock orders with distributor approval. Distributor-created invoices requiring franchise approval before stock application. Develop a clean Distributor dashboard for stock management, order approvals, and invoice handling. Maintain data consistency and performance across the centralized POS system. I focus on clean architecture, secure coding, and minimal disruption to the existing system. All changes will be well-tested and production-ready. I’m comfortable reviewing your current codebase first, then proposing a clear implementation plan before development begins. Looking forward to discussing your POS structure and starting the work. Best regards, Mostafa
