Greetings, I see you're looking to integrate Uganda's EFRIS API into your existing VB.NET POS system. This involves implementing features like e-invoicing, fiscal receipts, and QR code handling while ensuring compliance with URA regulations. My approach would involve a thorough understanding of the API documentation and leveraging my experience with similar tax compliance systems to ensure seamless integration. Having worked with VB.NET and MS SQL Server extensively, I have successfully tackled similar projects that required handling government APIs, which means I can effectively manage authentication, error handling, and response reconciliation for EFRIS. My focus will be on delivering a robust solution that meets all compliance requirements while enhancing the functionality of your POS system. Best regards, Saba Ehsan

Hello, I hope you are doing well. I’m a VB.NET and MS SQL specialist with hands-on experience building and upgrading POS systems and integrating tax/compliance APIs. My focus is clean architecture, secure data handling, and reliable SQL reporting. I have worked on Uganda URA EFRIS-like integrations and other government e-invoicing systems, implementing API auth, error handling, invoice validation, QR code processing, and reconciliation using VB.NET, REST, JSON/XML, and SQL Server. I can take this from design through deployment, ensuring URA EFRIS compliance, robust logging, retries, and test coverage. I will deliver a solid, production-ready integration tailored to your POS. Please feel free to contact me so we can discuss more details. Best regards, Billy Bryan

So, I can implement your request successfully in time. If you hire me, I'll do my best for you. I can start right now, please ping me.

@anirudhat

I have hands-on experience integrating Uganda's EFRIS API into VB.NET POS systems, including commodity code mapping, tax category handling, and the full e-invoice lifecycle from initialization through credit note management. My approach involves building a dedicated EFRIS service layer within your existing application that handles API authentication via the URA-provided keys, constructs compliant JSON payloads for invoice uploads, processes fiscal receipts with embedded QR codes, and implements robust error handling with automatic retry logic for failed submissions. I work extensively with MS SQL Server for transaction reconciliation and Crystal Reports for compliant invoice printing. I can start immediately and would be happy to share samples from similar EFRIS and KRA integrations I've completed.

Hey , I just went through your job description and noticed you need someone skilled in SQL, Crystal Reports, VB.NET, Software Architecture and Microsoft SQL Server. That’s right up my alley. You can check my profile — I’ve handled several projects using these exact tools and technologies. Before we proceed, I’d like to clarify a few things: Are these all the project requirements or is there more to it? Do you already have any work done, or will this start from scratch? What’s your preferred deadline for completion? Why Work With Me? Over 180 successful projects completed. Long-term track record of happy clients and repeat work. I prioritize quality, deadlines, and clear communication. Availability: 9am – 9pm Eastern Time (Full-time freelancer) I can share recent examples of similar projects in chat. Let’s connect and discuss your vision in detail. Kind Regards, Zain Arshad

Hi there! I see you need Uganda’s EFRIS API integrated into your VB.NET POS system for full tax compliance. I have strong experience with VB.NET, MS SQL Server, and e-invoicing integrations, including fiscal receipts, QR codes, and government APIs. I can handle authentication, error handling, and response reconciliation to ensure your system fully meets URA EFRIS standards. Do you have the API documentation and credentials ready for integration? I’m ready to start this integration immediately. Open chat now.

I need a fully automated bot that connects to the Deriv platform and hunts short-term arbitrage opportunities on the Volatility Indices. The core idea is simple: spot price discrepancies between synthetic markets, enter and exit fast, and repeat without human intervention. Here is what I expect: • A working script or application (Python, Node.js, or another language you are comfortable with) that logs in through the Deriv API, scans multiple Volatility markets in real time, and places trades the moment an arbitrage gap appears. • Adjustable parameters for stake size, maximum spread, trade frequency, and optional risk controls such as daily loss limits. • Clean, well-commented code plus a quick README so I can tweak settings and redeploy on my own server. • A short screen-share or video walkthrough proving the bot in action on a demo account. When you reply, please include links or repos that show similar trading automation you have built before; past work is my main filter. If you have clever ideas for latency control, smart order routing, or post-trade analytics, feel free to outline them as well—anything that tightens execution speed will be valued. I’m ready to move quickly once I see evidence that you have delivered high-frequency or arbitrage bots in the past.

@ratsoftware

hi I have done many applications and systems on vb.net and ready to show you some examples lets discuss Thanks

@jibrank00

Hello, I’ve reviewed your requirements and this project aligns well with my experience in VB.NET, MS SQL Server, and statutory e-invoicing integrations. I’m confident I can integrate Uganda URA EFRIS into your existing VB.NET POS system with full compliance. I’m new on the Freelancer platform, but I have 7+ years of experience working on tax and government API integrations, including systems similar to EFRIS, KRA/TIMS, VAT and e-invoicing platforms. I’ve handled API authentication, fiscal receipt generation, QR code handling, validation workflows, error reconciliation, and reporting in production POS environments. I’m comfortable working with government APIs, strict compliance rules, and legacy VB.NET systems backed by MS SQL Server, and I can provide relevant examples of similar completed work. Two quick questions: Is your POS currently using EFRIS-ready invoice structures, or will mapping be required? Do you need both online (real-time) and offline fallback handling for EFRIS submissions? Let’s jump into chat and get started right away. Best, Jibran
