Creating a restaurant POS (Point of Sale) system using Microsoft Access involves several steps, from planning and designing your database schema to implementing the user interface and reports. Below is a detailed guide to help you create a functional restaurant POS system using MS Access.

1. Planning Your POS System

a. Define Requirements
  • Order Management: Handle table orders, takeaways, and deliveries.
  • Menu Management: Manage items, categories, prices, and specials.
  • Employee Management: Track staff information and shifts.
  • Inventory Management: Keep track of stock levels and supplier information.
  • Reporting: Generate sales reports, inventory reports, and employee performance reports.
  • User Interface: Design forms for easy data entry and order processing.
b. Database Schema Design
  • Tables: Identify the necessary tables such as Orders, OrderDetails, MenuItems, Categories, Employees, Inventory, and Suppliers.
  • Relationships: Define relationships between tables, such as Orders linked to OrderDetails and MenuItems linked to Categories.

2. Creating the Database

a. Set Up Tables
  1. MenuItems Table
    • Fields: ItemID (AutoNumber, Primary Key), CategoryID (Number), ItemName (Text), Price (Currency), Description (Text), StockLevel (Number)
  2. Categories Table
    • Fields: CategoryID (AutoNumber, Primary Key), CategoryName (Text)
  3. Orders Table
    • Fields: OrderID (AutoNumber, Primary Key), OrderDate (Date/Time), TableNumber (Number), EmployeeID (Number), TotalAmount (Currency)
  4. OrderDetails Table
    • Fields: OrderDetailID (AutoNumber, Primary Key), OrderID (Number), ItemID (Number), Quantity (Number), Price (Currency)
  5. Employees Table
    • Fields: EmployeeID (AutoNumber, Primary Key), FirstName (Text), LastName (Text), Position (Text), Shift (Text)
  6. Inventory Table
    • Fields: InventoryID (AutoNumber, Primary Key), ItemID (Number), QuantityInStock (Number), ReorderLevel (Number)
  7. Suppliers Table
    • Fields: SupplierID (AutoNumber, Primary Key), SupplierName (Text), ContactName (Text), Phone (Text), Email (Text)
b. Define Relationships
  • Link MenuItems to Categories via CategoryID.
  • Link OrderDetails to Orders via OrderID.
  • Link OrderDetails to MenuItems via ItemID.
  • Link Orders to Employees via EmployeeID.
  • Link Inventory to MenuItems via ItemID.

3. Creating Forms

a. Order Entry Form
  1. Main Form (Orders)
    • Use Orders table as the data source.
    • Include fields: OrderID, OrderDate, TableNumber, EmployeeID, TotalAmount.
  2. Subform (OrderDetails)
    • Use OrderDetails table as the data source.
    • Include fields: OrderDetailID, OrderID, ItemID, Quantity, Price.
  3. Add Controls
    • ComboBox for EmployeeID (to select employee).
    • ComboBox for ItemID (to select menu item).
    • TextBoxes for Quantity and Price.
b. Menu Management Form
  • Use the MenuItems table as the data source.
  • Include fields: ItemID, CategoryID, ItemName, Price, Description, StockLevel.
  • ComboBox for CategoryID to select category.
c. Inventory Management Form
  • Use the Inventory table as the data source.
  • Include fields: InventoryID, ItemID, QuantityInStock, ReorderLevel.
  • ComboBox for ItemID to select menu item.
d. Employee Management Form
  • Use the Employees table as the data source.
  • Include fields: EmployeeID, FirstName, LastName, Position, Shift.

4. Creating Queries

a. Sales Report Query
  • Query Name: SalesReport
  • Fields: OrderID, OrderDate, EmployeeID, TotalAmount.
  • Aggregate function: Sum TotalAmount grouped by OrderDate and EmployeeID.
b. Inventory Report Query
  • Query Name: InventoryReport
  • Fields: ItemID, ItemName, QuantityInStock, ReorderLevel.
  • Criteria: QuantityInStock <= ReorderLevel.
c. Employee Performance Query
  • Query Name: EmployeePerformance
  • Fields: EmployeeID, FirstName, LastName, Position.
  • Join with Orders to calculate total sales per employee.

5. Creating Reports

a. Sales Report
  • Use SalesReport query as the data source.
  • Group by OrderDate.
  • Include totals for TotalAmount.
b. Inventory Report
  • Use InventoryReport query as the data source.
  • Include ItemID, ItemName, QuantityInStock, ReorderLevel.
c. Employee Performance Report
  • Use EmployeePerformance query as the data source.
  • Include EmployeeID, FirstName, LastName, TotalSales.

6. Implementing Business Logic

a. Calculating Total Amount
  • In the Order Entry Form, create a button to calculate the total amount for an order.
  • Use VBA code to sum the Price * Quantity for each item in the order.
  Private Sub btnCalculateTotal_Click()
    Dim rs As DAO.Recordset
    Dim total As Currency
    total = 0
    Set rs = Me.RecordsetClone
    rs.MoveFirst
    Do While Not rs.EOF
        total = total + (rs!Quantity * rs!Price)
        rs.MoveNext
    Loop
    Me.TotalAmount = total
    rs.Close
    Set rs = Nothing
End Sub
b. Updating Inventory Levels
  • After processing an order, update the QuantityInStock in the Inventory table.
  • Use VBA code to subtract the Quantity from the QuantityInStock for each item in the order.
  Private Sub btnProcessOrder_Click()
    Dim rsOrderDetails As DAO.Recordset
    Dim rsInventory As DAO.Recordset
    Set rsOrderDetails = Me.OrderDetails.Form.RecordsetClone
    Set rsInventory = CurrentDb.OpenRecordset("Inventory")
    rsOrderDetails.MoveFirst
    Do While Not rsOrderDetails.EOF
        rsInventory.FindFirst "ItemID = " & rsOrderDetails!ItemID
        If Not rsInventory.NoMatch Then
            rsInventory.Edit
            rsInventory!QuantityInStock = rsInventory!QuantityInStock - rsOrderDetails!Quantity
            rsInventory.Update
        End If
        rsOrderDetails.MoveNext
    Loop
    rsOrderDetails.Close
    rsInventory.Close
    Set rsOrderDetails = Nothing
    Set rsInventory = Nothing
End Sub

7. Testing and Deployment

a. Test Functionality
  • Test all forms and reports to ensure they work correctly.
  • Validate data entry and ensure calculations are accurate.
  • Test business logic to confirm it updates inventory levels correctly.
b. User Training
  • Train staff on how to use the POS system.
  • Provide documentation or a user manual with step-by-step instructions.
c. Deployment
  • Deploy the Access database on the restaurant’s network.
  • Ensure regular backups are taken to prevent data loss.

8. Advanced Features (Optional)

a. Touchscreen Interface
  • Design forms with larger buttons and controls for touchscreen compatibility.
  • Use macros to handle button clicks and form navigation.
b. Barcode Scanning
  • Integrate barcode scanning for inventory management.
  • Use VBA to handle barcode input and lookup items in the MenuItems table.
c. Integration with Accounting Software
  • Export sales data to accounting software like QuickBooks or Xero.
  • Use VBA to generate export files in the required format (e.g., CSV).
d. Customer Loyalty Program
  • Implement a loyalty program to track customer purchases and reward points.
