<h3>Power Soft Empowers EasymealCo with Robust Billing Tool Enhancements & Long-Term Support</h3> <p><b>Executive Summary:</b><br />Power Soft forged a multi-year, dynamic partnership with EasymealCo, providing critical enhancements, ongoing support, and agile development for their core billing application. Through responsive communication, meticulous problem-solving, and expert ASP.NET Core development, Power Soft transformed a challenging system into a stable and efficient tool, significantly improving EasymealCo's invoicing operations and user satisfaction. This collaboration highlights Power Soft's ability to manage complex, long-term custom software development projects and navigate critical incidents with professionalism.</p><p><b>The Challenge: Stabilizing and Optimizing a Mission-Critical Billing System</b></p><p>EasymealCo, a growing French enterprise, relied on a custom-built ASP.NET Core MVC billing tool for its core invoicing and client management operations. While functional, the application suffered from several persistent issues and lacked crucial modern features, which impacted its efficiency and user experience. Key challenges included:</p><ul><li style="font-weight: 400;" aria-level="1"><b>Inaccurate VAT Calculations:</b> Problems with VAT logic, especially for subscription invoices.</li><li style="font-weight: 400;" aria-level="1"><b>Complex Invoice Numbering:</b> Need for robust and flexible invoice and credit note numbering, including handling gaps and specific client requirements.</li><li style="font-weight: 400;" aria-level="1"><b>UI/UX Inefficiencies:</b> Lack of user-friendly features like thousand separators, advanced table sorting/filtering, and intuitive data entry.</li><li style="font-weight: 400;" aria-level="1"><b>Security Vulnerabilities:</b> Need for SSL implementation and reliable certificate management.</li><li style="font-weight: 400;" aria-level="1"><b>Reporting Inconsistencies:</b> Issues with data accuracy and formatting in generated Excel reports.</li><li style="font-weight: 400;" aria-level="1"><b>Feature Gaps:</b> Missing functionalities like editing credit notes, customizable proposal PDFs, and streamlined email templating.</li><li style="font-weight: 400;" aria-level="1"><b>Scalability & Maintenance:</b> The client needed a reliable partner for ongoing bug fixes, feature requests, and proactive system maintenance.</li></ul><p><b>Power Soft's Agile & Collaborative Solution: A Journey of Continuous Improvement</b></p><p>Power Soft adopted a highly communicative and agile approach to address EasymealCo's evolving needs.</p><ol><li style="font-weight: 400;" aria-level="1"><b>Streamlined Communication & Project Management:</b><ul><li style="font-weight: 400;" aria-level="2"><b>Instantaneous Support:</b> Utilized WhatsApp for rapid discussion of minor fixes and approvals.</li><li style="font-weight: 400;" aria-level="2"><b>Transparent Task Tracking:</b> Implemented a shared Google Sheet for managing to-do lists, prioritizing tasks (urgent, low-priority), and ensuring clarity for both teams.</li></ul></li><li style="font-weight: 400;" aria-level="1"><b>Iterative Development & Rigorous Testing:</b><ul><li style="font-weight: 400;" aria-level="2"><b>Dedicated Test Environment (UAT):</b> Deployed all changes to a User Acceptance Testing (UAT) server on AWS for client validation before live deployment.</li><li style="font-weight: 400;" aria-level="2"><b>Phased Rollouts:</b> Ensured stability by deploying approved changes to the main production environment systematically.</li></ul></li><li style="font-weight: 400;" aria-level="1"><b>Key Technical Interventions & Enhancements:</b><ul><li style="font-weight: 400;" aria-level="2"><b>Core Logic Overhaul:</b> Rectified VAT calculation errors, particularly for subscription-based invoices.</li><li style="font-weight: 400;" aria-level="2"><b>Advanced Invoice Numbering System:</b> Engineered a sophisticated system to manage invoice and credit note sequencing, intelligently filling gaps from deleted invoices and maintaining distinct series for credit notes (YYYYMM##).</li><li style="font-weight: 400;" aria-level="2"><b>Security Fortification:</b> Successfully set up SSL certificates via Certbot on their IIS server (hosted on AWS EC2), and diligently managed manual renewals, eventually configuring auto-renewal for enhanced security and convenience.</li><li style="font-weight: 400;" aria-level="2"><b>Database & Performance Optimization:</b> Diagnosed and resolved issues related to data integrity, query performance, and report generation from their MySQL database.</li><li style="font-weight: 400;" aria-level="2"><b>Feature Implementation:</b> Developed new functionalities including editable credit notes, customizable proposal fields (delivery date, comments, payment methods), enhanced email templates, and options for bulk PDF downloads.</li><li style="font-weight: 400;" aria-level="2"><b>Subscription & Automation:</b> Refined the automated generation of subscription invoices, addressing issues with scheduling, next-generation dates, and potential duplicate generation.</li></ul></li></ol> <img width="1899" height="862"

<p><b>Project Overview:</b><br />Power Soft, through Principal Consultant Md. Monir Hossain, developed a Minimum Viable Product (MVP) for a client's core Fraud Detection as a Service (FDaaS) API. The project focused on creating a functional API for real-time fraud risk scoring, enabling the client to validate their concept and launch an initial offering. This case study highlights Power Soft's agile development, technical proficiency, and client-centric approach.</p><p><b>The Challenge:</b><br />The client needed a functional API to serve as the backbone of their new FDaaS platform. The primary requirement was an endpoint capable of receiving user data (email, IP, device ID, etc.), applying predefined fraud detection rules, and returning a real-time fraud score, risk level, and reason codes. The initial scope was a rule-based engine, with plans for future scalability.</p> <img width="1899" height="862" src="https://powersoft.agency/wp-content/uploads/2022/05/FDaaS-portal-Dashboard.jpg" alt="" srcset="https://powersoft.agency/wp-content/uploads/2022/05/FDaaS-portal-Dashboard.jpg 1899w, https://powersoft.agency/wp-content/uploads/2022/05/FDaaS-portal-Dashboard-300x136.jpg 300w, https://powersoft.agency/wp-content/uploads/2022/05/FDaaS-portal-Dashboard-1024x465.jpg 1024w, https://powersoft.agency/wp-content/uploads/2022/05/FDaaS-portal-Dashboard-768x349.jpg 768w, https://powersoft.agency/wp-content/uploads/2022/05/FDaaS-portal-Dashboard-1536x697.jpg 1536w" sizes="(max-width: 1899px) 100vw, 1899px" /> <p><b>Power Soft's Solution & Execution:</b><br />A collaborative and iterative development process was implemented:</p><ol><li style="font-weight: 400;" aria-level="1"><b>Requirement Definition:</b> Through detailed discussions, including a video call, our consultant worked with the client to solidify requirements.
