Formulas Required for Dynamic Functionality

• Total Amount (Invoice Master): =Quantity Sold * Selling Price per Unit
• In Stock Quantity (Inventory Ledger): Uses a SUMIF formula to track total inventory changes: =SUMIFS(Invoice Master!C:C, Invoice Master!B:B, "Item ID") - SUMIFS(Invoice Master!E:E, Invoice Master!B:B, "Item ID")
• Reorder Alert Flag: Conditional logic: =IF(In Stock Quantity <= Reorder Level, "Reorder Required", "")
• Outstanding Invoices Count: =COUNTIF(Payment Status, "Pending") + COUNTIF(Payment Status, "Overdue")

Conditional Formatting Rules

• Low Stock Alert: Apply red fill with white text to cells in the “In Stock Quantity” column when value ≤ Reorder Level.
• Pending/Overdue Invoices: Highlight rows in Invoice Master where Payment Status = "Pending" (yellow) or "Overdue" (red).
