Monthly Summary Dashboard: A visual summary sheet that displays key metrics including monthly sales volume, stock turnover rate, low-stock alerts, and revenue trends.
Inventory Master List: A static reference table containing all product codes, descriptions, categories, unit costs, and initial inventory levels at the start of the month.

Invoice ID Auto-increment: =IF(A2="","",MAX($B$1:B1)+1)
Description Auto-fill: =VLOOKUP(B2, 'Inventory Master List'!$A:$F, 2, FALSE)
Unit Cost Auto-fill: =VLOOKUP(B2, 'Inventory Master List'!$A:$F, 4, FALSE)
Total Amount: =C2*D2
Stock After Transaction (Cumulative): =IF(ROW()=2,'Inventory Master List'!$E$2,INDEX('Inventory Master List'!$E:$E,MATCH(B3,'Inventory Master List'!$A:$A,0))+SUMIFS($F:$F,$C:$C,"<="&ROW()-1,$B:$B,B3))
Reorder Alert Indicator: =IF(INDEX('Inventory Master List'!$E:$E,MATCH(B2,'Inventory Master List'!$A:$A,0)) <= INDEX('Inventory Master List'!$F:$F,MATCH(B2,'Inventory Master List'!$A:$A,0)), "Low Stock", "")

Conditional Formatting

To enhance usability and visual tracking:

Low Stock Items: Applies red fill with white text when current stock ≤ reorder point.
Sale Transactions: Blue background for rows where Transaction Type = "Sale".
Purchase Orders: Green background for "Purchase" entries.
Negative Quantity Alerts: Yellow highlight when quantity is negative (except on return transactions, which should be allowed).
Duplicate Invoice ID: Red border if an invoice ID is repeated.
