CREATE TABLE Products ( ProductID INT PRIMARY KEY IDENTITY, PName VARCHAR(100), Price DECIMAL(18, 2), Stock INT ); CREATE TABLE Invoices ( InvoiceID INT PRIMARY KEY IDENTITY, CustomerName VARCHAR(100), InvoiceDate DATE, TotalAmount DECIMAL(18, 2) ); Use code with caution. 3. Setting up the Connection (Connection Class)
Use a KeyDown event on the ProductID textbox to trigger a search when a barcode scanner enters a value.
For larger enterprises with high transaction volumes, Microsoft SQL Server is the preferred choice. It offers superior performance, security, and scalability. Projects using SQL Server often employ advanced database features like stored procedures .
Private Sub frmBilling_Load(sender As Object, e As EventArgs) Handles MyBase.Load InitializeCartTable() GenerateInvoiceNumber() LoadProducts() LoadCustomers() End Sub vb.net billing software source code
End Class
Websites like SourceCodester and TechRooms are also excellent resources. These sites often feature well-documented projects with step-by-step installation guides. One prime example is the Automated Beer Parlour Billing System available on SourceCodester. This project, developed using VB.NET and MS Access, is a complete billing solution that includes login modules, POS transaction capabilities, and sales receipt generation. The same project, often referred to as the Pub Billing System , can also be found on sites like TechRooms, where the author encourages users to download and modify the source code to improve their programming skills. A more recent example from 2024 is a Food POS system on GitHub that uses Visual Studio 2019 and includes an audit trail and report generation.

To make your VB.NET billing software professional, consider adding:
#Region "Printing Engine Routines"Private Sub PrintInvoiceReceipt()Dim printDoc As New PrintDocument()AddHandler printDoc.PrintPage, AddressOf PrintPageHandler
: Options to generate PDF invoices or print receipts directly. Top Sources for VB.NET Billing Source Code Using Visual Studio and SQL Server
: Use System.Data.SqlClient or System.Data.OleDb to connect to SQL Server or MS Access for saving invoices. 🖥️ Building the User Interface
Creating your own billing software in VB.NET is a classic project for developers looking to master database management and CRUD (Create, Read, Update, Delete) operations. Using Visual Studio and SQL Server, you can build a robust system that handles everything from inventory to professional invoice generation.

Instead of coding the database structure, you start with a working skeleton. Your job shifts from "plumbing" to "customizing."
