POS System Developer Needed

@ykarora26

With extensive experience in .NET and WPF, I understand the need to stabilize and enhance your POS system. I have successfully completed similar POS projects focusing on bug fixes, feature enhancements, and report generation. Could you provide more details on the current bug list and any specific requirements for the reporting and accounting checks? Regards, Yogesh Kumar

Hello, I will stabilize your .NET 8 WPF POS system, fix the critical bugs across sales, purchase, and inventory flows, then complete the missing features: hold/recall, mixed payments with partial/credit, lot/serial handling, and journal posting consistency for all transaction types. On a recent WPF POS project, setting up a staging SQLite database with the client's test data caught 40+ edge cases before touching production builds. I will do the same here. Questions: 1) Is the receipt/invoice printing targeting a specific thermal printer model, or do you need a generic ESC/POS driver? 2) For user roles, do you have a defined permission matrix, or should I propose one based on the workflows? Looking forward to discussing further. Best regards, Kamran

@NayaPakistan

Hi, I understand you need a .NET 8 WPF developer to stabilize and complete your POS system, focusing on critical flows and essential features. My approach would be to first thoroughly review your provided source code, bug list, and sample data to pinpoint stabilization issues. I'll then systematically address the critical bugs in sales, purchase, and inventory, followed by implementing the specified feature completions for sales workflows, payments, purchase orders, and inventory management. I will ensure all features are robust with improved validation and error handling, and deliver a reliable release build with clear deployment guidance and documentation. My focus will be on providing a stable, accurate, and maintainable system with efficient communication throughout. Could you please provide details on the complexity of the user roles/permissions and lot/serial handling requirements for a more precise estimate? Regards, Muhammad Azeem

From the scope, it looks like the system is already functional in parts—the challenge is getting it to a stable point without introducing regressions while finishing the workflows that are still incomplete. I'd start by getting the project building cleanly, reproducing every issue from your bug list, and tightening the core sales, purchasing, and inventory flows before adding the remaining features. Once those are reliable, I'd move on to reporting, accounting consistency, backup/restore, printing, and the final deployment package with handover documentation. I also like to add a small regression test pass around the checkout flow since that's usually where POS issues surface after changes elsewhere. I've worked on large desktop business applications where keeping SQLite data consistent across inventory and financial transactions was just as important as adding new features, so I understand the balance between fixing and finishing. For the milestone pricing, total cost, and timeline, I'd rather base them on the existing codebase and bug list than guess. Once I review those, I can provide a realistic M1–M4 breakdown with fixed pricing, included scope, exclusions, and post-delivery support. I'm ready to start as soon as you share the repository.

@Hubready

Hello!, I am a Florida-based senior software engineer(frontend, backend, ecommerce, etc) with about 15 years of experience, and I read your POS project carefully. You need someone to complete and stabilize a .NET 8 / WPF POS system, not just add features, but make it reliable, clean, and production-ready. I’ve built and stabilized C#, .NET, WPF, SQLite, and database-driven desktop systems, where the real work is fixing edge cases, UI flow, state handling, and making sure everything behaves consistently in real use. My approach would be: 1. Review the current codebase and identify stability issues 2. Trace the POS workflow end to end, including database operations 3. Fix bugs, tighten logic, and clean up the WPF UI behavior 4. Test the key flows thoroughly before handoff Could you please clarify the following questions to help me better understand the project? 1. Which parts are currently unstable, checkout, inventory, receipts, syncing, or something else? 2. Is the app fully local with SQLite only, or does it also connect to PHP or external services? 3. Do you already have the source code and known issues, or should I audit the system first? If helpful, I can start with a quick technical review and give you a clear fix plan before changing anything important. I’m the kind of person who pays attention to the details, and that matters a lot on POS work.

Your POS system will fail in production if the SQLite write-ahead logging is not configured correctly under concurrent transactions. WPF data binding errors in MVVM can also cause silent crashes during high-volume sales periods. Quick questions - are you handling inventory deductions atomically with payment commits to prevent overselling? And do your user roles need field-level permissions or just module-level access? Here is the architectural approach: - .NET 8 + WPF: Refactor MVVM command bindings to prevent UI thread blocking during database writes and implement async repository pattern for all CRUD operations. - SQLITE DATABASE MANAGEMENT: Add transaction isolation with WAL mode, implement optimistic locking for inventory adjustments, and create indexed views for reporting queries. - ACCOUNTING + AUDIT TRAIL: Build double-entry journal posting engine with rollback support and immutable audit logs tied to user sessions for compliance. I've built 4 retail POS systems processing 500+ daily transactions with zero data loss. Let's schedule a 20-minute call to review your codebase architecture before I send milestone pricing.

@kishanbwts

I’ve worked on a POS system for a retail client where I stabilized WPF sales and inventory flows and upgraded payment features to handle partial and mixed payments. Your stack and bug/feature list look clear and address typical POS pain points that I’ve solved before. For stabilization, focus will be on fixing the critical bugs in sales, purchase, and inventory flows first, ensuring smooth runtime and build without crashes or data inconsistencies. I’ll then complete the sales workflow and payments with all the requested cases like discounts and holds, plus purchase orders with returns. For inventory, I suggest handling lot/serial tracking using SQLite transactions to avoid data loss, and adding audit trail linked to user roles to meet compliance needs. Reporting will include cross-checks between journal posts and sales data to keep accounting reliable. Can you share the biggest issue currently in sales or payments? Also, do you prefer print templates built-in or integrate with existing printer drivers? Milestones could be: M1: Stabilization & critical bugs fix M2: Sales + payments features M3: Purchase, inventory + roles/audit M4: Reporting, backup, docs & deployment I’ll provide fixed prices and timelines per milestone after detailed review. Total duration likely 6-8 weeks. Post-delivery support can cover 2 weeks for bug fixes and clarifications. Ready to review your code and start as soon as you send it.
