I need a fully-featured accounting system written in C# with a SQL Server back-end, and I expect the complete, well-documented source code. The application has to cover day-to-day accounting operations without errors and be simple for end-users to navigate. At minimum it must include these functional areas: • Invoicing • Inventory control • Expense and income tracking • Sales management • User and role management • Purchasing management • Employee records • Comprehensive, printable reports Please build it as a clean Visual Studio solution, using standard design patterns and clear naming so future developers can extend it easily. All database objects (tables, views, stored procedures) should be created through scripts that I can run on a fresh SQL Server instance. Before delivery I will test: 1. Accurate posting of every transaction to the ledger. 2. Real-time stock level updates after sales or purchase entries. 3. Role-based access preventing unauthorized operations. 4. Exportable reports (PDF or Excel) that match on-screen data. Send the executable, source, and SQL scripts in a single archive, along with a brief setup guide. If anything is unclear you can message me on Facebook at [login to view URL] for quick clarifications.

Hi I can build a complete C# accounting system with a SQL Server backend, clean Visual Studio solution structure, documented source code, and runnable SQL scripts for fresh database setup. The main technical challenge is making sure every invoice, purchase, sale, expense, income entry, and stock movement posts accurately to the ledger while keeping inventory and reports synchronized. I can implement modules for invoicing, inventory control, expense/income tracking, sales, purchasing, employee records, user/role management, and printable PDF/Excel reports. The system can be structured using clean design patterns, role-based access control, validation rules, transaction-safe database operations, stored procedures, views, and clear naming conventions. I will also include setup documentation, database scripts, executable files, and source code in a single organized archive. All communication and clarification can stay safely within the Freelancer platform so the full scope remains documented. Thanks, Hercules

Hey, I will deliver the full C# accounting system — invoicing, inventory, expense/income tracking, sales, purchasing, employee records, and role-based user management — as a clean Visual Studio solution with all SQL Server scripts ready to run on a fresh instance. For the ledger architecture, I will implement a double-entry posting engine where every transaction creates balanced debit/credit entries automatically. This prevents the silent mismatches that often surface in single-entry systems and makes your reconciliation reports trustworthy from day one. Stock levels will update transactionally alongside sales and purchase postings — so inventory and financials stay in sync without batch jobs. Questions: 1) Are you targeting WinForms, WPF, or a web front-end like ASP.NET for the UI layer? Looking forward to talking through the details. Kamran

Hi Asem A., Last week I delivered a very similar C# + SQL Server accounting system, so I’m confident I can handle this really well. My Questions. - Do you want a desktop app (WinForms/WPF) or a web app (ASP.NET Core), and any UI preferences for navigation and data entry? - Should all writes use stored procedures only, or is EF Core acceptable if I provide full SQL scripts; and for exports do you prefer RDLC-based PDF/Excel or another library? My Suggestions. - Use a Clean Architecture (Domain, Application, Infrastructure, UI) with clear naming and unit tests around the ledger posting engine for long‑term maintainability. - Enforce SQL transactions, foreign keys, and rowversion for concurrency, plus proper indexing on ledgers, inventory, and sales to keep performance stable as data grows. My Execution Plan. - Confirm scope: modules, roles, chart of accounts, taxes, inventory valuation (FIFO/Avg), report list. - Design the database schema, views, and stored procedures; deliver fresh-install SQL scripts. - Build a clean Visual Studio solution with layered architecture and standard patterns (Repository, Unit of Work). - Implement modules: invoicing, sales, purchases, inventory updates (real-time), expenses/income, employees, and role-based access. - Implement a double‑entry posting engine with audit trail; validate balanced entries. - Add reports with on-screen views and export to PDF/Excel; ensure exports match on-screen

It’s overwhelming when an accounting system is clunky, error-prone, or requires users to hunt for features, especially when you’re responsible for accurate ledgers, real-time stock updates, and secure role management. Every small mistake can ripple out, causing costly confusion or unauthorized access. You’ll get a clean, well-documented C# solution with a SQL Server back end that keeps daily accounting operations smooth, lets you generate exportable reports that always match what you see on screen, and ensures every transaction posts correctly. First, I’ll design the database with scripts you can run on any fresh SQL Server. Then, I’ll build the application in Visual Studio using clear patterns and naming for easy future updates. Finally, I’ll package the executable, full source, and setup guide so you can get started right away. Would you like to discuss any of the functional areas in more detail before I begin?

Hello, I will use c sharp with asp net core architecture for the application layer and sql server for relational data management ensuring strong consistency across accounting modules. the system will be structured in a layered architecture separating presentation, business logic and data access so invoicing, inventory, expenses, sales, purchasing and employee management remain modular and easy to maintain. entity framework core will be used for controlled data interaction while raw sql scripts will define all tables, views and stored procedures so the database can be recreated from scratch. ledger accuracy will be handled through transaction based processing ensuring every financial entry is recorded atomically and reflected across reports and inventory in real time. role based authentication and authorization will control access across users and employees. reporting will be generated through ssrs or pdf and excel export services to match on screen values exactly. Let's have a detailed discussion, as it will help me give you a complete plan, including a timeline and estimated budget. I will share my portfolio in chat I look forward to hear from you.
