This paper explores the design, architecture, and implementation of a desktop-based billing software application using VB.NET (Visual Basic .NET) within the .NET framework. The objective is to develop a robust, user-friendly system capable of managing inventory, generating invoices, and tracking transaction history for Small to Medium Enterprises (SMEs). The proposed system utilizes a three-tier architecture, separating the presentation layer, business logic, and data access layers to ensure maintainability and scalability. A local SQL database is employed for data persistence. The paper details the database schema, key code modules, and the rationale behind choosing VB.NET for Rapid Application Development (RAD) in business contexts.

: Monitor which invoices are paid, pending, or overdue, with the ability to update statuses post-save. Export Capabilities : Allow users to export billing data and invoices as files for easy record-keeping. User Role Management

Building billing software in VB.NET is an excellent way to understand database transactions, UI event handling, and business logic. The source code provided here is functional and can be directly integrated into a retail environment with minor modifications.

Proper database setup is a critical step in your development journey:

' Check if already in cart Dim existingRow() As DataRow = cartTable.Select($"ProductID = productID") If existingRow.Length > 0 Then existingRow(0)("Quantity") += 1 Dim qty As Integer = Convert.ToInt32(existingRow(0)("Quantity")) Dim totalBeforeGST As Decimal = qty * price Dim gstAmt As Decimal = totalBeforeGST * (gstPercent / 100) existingRow(0)("GST_Amount") = gstAmt existingRow(0)("Total") = totalBeforeGST + gstAmt Else Dim gstAmt As Decimal = price * (gstPercent / 100) Dim totalWithGST As Decimal = price + gstAmt cartTable.Rows.Add(productID, pName, 1, price, gstPercent, gstAmt, totalWithGST) End If CalculateTotals() txtProductCode.Clear() txtProductCode.Focus() Else MessageBox.Show("Product not found!") End If End If End Sub

: Double-check that all component identifier properties match the naming conventions listed in the UI section (such as dgvInvoiceItems , btnSaveInvoice ). Export Capabilities : Allow users to export billing

To scale this application into an enterprise-ready point-of-sale system, consider adding the following features:

: ComboBox ( cmbProducts ), TextBox ( txtPrice , txtQuantity ), Button ( btnAddToGrid )

Private Sub btnAddItem_Click(sender As Object, e As EventArgs) Handles btnAddItem.Click Dim qty As Integer = Integer.Parse(txtQuantity.Text) Dim price As Decimal = Decimal.Parse(txtPrice.Text) Dim product As String = txtProduct.Text
