Step 1: Worksheet Design

• Open Excel and create a new workbook.
• Set up the following sheets:
  • Dashboard
  • Products
  • Customers
  • Suppliers
  • Orders
• Design the layout for each sheet, including headers for relevant data fields (e.g., Product ID, Product Name, Quantity, Price, etc.).

Step 2: Create the Dashboard

• On the Dashboard sheet, create a summary of key metrics:
  • Total Products
  • Total Customers
  • Total Orders
• Use formulas to link these metrics to the respective sheets for real-time updates.

Step 3: Set Up the Products Sheet

• Create columns for:
  • Product ID
  • Product Name
  • Supplier
  • Quantity in Stock
  • Price per Unit
• Enter sample data to visualize how your inventory will look.

Step 4: Set Up the Customers Sheet

• Create columns for:
  • Customer ID
  • Customer Name
  • Contact Information
  • Address
• Populate with example customer data as needed.

Step 5: Set Up the Suppliers Sheet

• Create columns for:
  • Supplier ID
  • Supplier Name
  • Contact Information
  • Address
• Add sample supplier data.

Step 6: Set Up the Orders Sheet

• Create columns for:
  • Order ID
  • Customer ID
  • Product ID
  • Quantity Ordered
  • Order Date
• This sheet will track all sales transactions.

Step 7: Create a Selection Menu

• Use Excel’s Data Validation feature to create drop-down menus for selecting products and customers in the Orders sheet:
  • Select the cell where you want the drop-down.
  • Go to Data > Data Validation > List and select the range of your products or customers.

Step 8: Implement the Selection Change Event

• Use VBA to create an event that triggers when a selection is made in the drop-down menus.
• Open the VBA editor and insert the following code into the relevant worksheet:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Not Intersect(Target, Me.Range("A2")) Is Nothing Then
        ' Code to refresh product details based on selection
    End If
End Sub

Step 9: Saving Items

• Create a button that allows users to save new items in the Products sheet:
  • Use a form to gather data and write a macro that inputs this data into the sheet.

Step 10: Managing Customers

• Similar to saving items, create functionalities to:
  • Add new customers
  • Update existing customer information
  • Delete customers

Step 11: Managing Orders

• Implement functionalities to:
  • Add new orders
  • Update existing orders
  • Delete orders
  • Load saved orders for review

Step 12: Print Orders

• Design a print-friendly version of the order that can be generated with a button click.
• Use the Page Setup features in Excel to format the print layout.

Step 13: Creating Graphs

• Use Excel's charting tools to visualize sales data over time.
• Select your data range and choose the appropriate chart type from the Insert tab.

Conclusion

You have now created a complete inventory management system in Excel from scratch. This system allows you to manage products, customers, suppliers, and orders all in one place.
