Formulas Required

The template leverages dynamic Excel formulas for automation and real-time tracking:

• =SUMIF(InventoryLedger!C:C,A2,InventoryLedger!F:F): Pulls unit cost from ledger by Item Code.
• =SUMIFS(InvoiceEntry!G:G,InvoiceEntry!I:I,"Inbound") - SUMIFS(InvoiceEntry!G:G,InvoiceEntry!I:I,"Outbound"): Calculates net inventory change.
• =VLOOKUP(ItemCode,InventoryLedger!A:H,7,FALSE): Retrieves current unit cost in real time.

Conditional Formatting

Enhances readability and highlights critical information:
