Formulas Required

The template relies on dynamic formulas to ensure real-time accuracy:

• Days in Inventory: `=IF([Current Stock]>0, (AVERAGE(B2:B13) * 30)/[Current Stock], 0)` — based on average monthly usage.
• Stock Status: `=IF(AND([Current Stock] <= [Minimum Level]), "Critical", IF([Current Stock] < [Minimum Level]*1.5, "Low", "In Stock"))`
• Reorder Flag: `=IF([Current Stock] <= [Minimum Level], "Yes", "")` — used to flag items needing restocking.
• Total Monthly Sales (Monthly Report): `=SUMIFS(Transactions!$Q:$Q, Transactions!$D:$D, "Sale", Transactions!$A:$A, ">="&DATE(2024,1,1), Transactions!$A:$A,"<"&DATE(2024,1,31))`
• Inventory Turnover (Dashboard): `=SUMIFS(Transactions!$Q:$Q, Transactions!$D:$D, "Sale") / AVERAGE([Average Stock])`
