Our Client is a US-based fintech startup founded by private investors with a mission to streamline operations for the restaurant industry. The company set out to develop a comprehensive management and point-of-sale solution designed to address common pain points in restaurant operations and improve customer service delivery.
The primary goal was to build a minimum viable product (MVP) to launch as a pilot project with a partner restaurant, gather real-world feedback, and use those insights to enhance functionality and scale to additional restaurant operators.

Building a reliable POS and payment platform required solving complex challenges across software, hardware integrations, and business operations. Developex partnered with the Client’s team throughout the development process to translate business requirements into practical technical solutions and deliver an MVP ready for market validation.
Restaurants struggled to manage and track fees, discounts, and service charges applied across different items and categories, making it difficult to optimize pricing strategies and understand true profitability.
Existing solutions did not provide integrated payment processing, forcing restaurants to manage payments, refunds, and tips across multiple disconnected systems and payment methods (cash and credit cards).
Restaurant operators lacked a unified platform to manage critical operations including staff roles, menu configuration, inventory, and integrated POS workflows, leading to inefficiencies and data silos.
Manual order creation processes and delayed communication between front-of-house and kitchen staff created bottlenecks that slowed service and reduced customer satisfaction.
Unreliable connections between POS terminals, payment devices, printers, and cash management systems—especially under poor network conditions—disrupted operations and created data inconsistencies.
The project started with undefined requirements and had to navigate legacy code constraints while simultaneously delivering new features under aggressive timelines.
We designed and built a centralized, integrated platform combining a web-based management system with an Android-powered POS application and unified payment processing.
A comprehensive management portal built with .NET and React.js enabling restaurant owners and managers to configure business rules, manage staff, design menus, set up devices, and access detailed financial and operational reports.
Unified payment operations through Dejavoo integration, enabling seamless handling of payments, refunds, and tips across all payment methods without requiring separate systems or manual reconciliation.
Granular permission system allowing managers to define staff roles, control access to POS functionality, and audit staff activities for security and accountability.
Centralized device provisioning and management ensuring stable, real-time connections between POS terminals, payment terminals, kitchen displays, and cash management systems—with failover capabilities for offline scenarios.
A purpose-built point-of-sale application allowing restaurant staff to quickly create and manage orders, process payments (cash and card), and communicate order details in real time to kitchen displays and other connected devices.
Flexible menu management system supporting item creation, category organization, customizable additions and pricing variations, enabling restaurants to quickly adapt their offerings and pricing strategies.
We established a comprehensive product vision and delivery roadmap with clear acceptance criteria for each feature, enabling systematic feature delivery and transparent stakeholder communication.
We conducted a complete backend and frontend rebuild from scratch, applying modern development practices and code standards while continuing to deliver new features without interrupting development momentum.
