Formulas Required

The template uses a combination of lookup, calculation, and validation formulas to ensure accuracy and efficiency:

• VLOOKUP / XLOOKUP: Used in Invoice Generator to pull product name, unit price, and cost from Inventory Master List using Item ID.
• IF & AND Statements: Validate that Quantity Sold ≤ Current Stock before allowing invoice submission.
• SUMIFS: Calculate total sales per category or customer across the Sales & Transactions Log.
• COUNTIFS: Track number of times an item has been sold or reordered.
• DATEDIF: Calculate time between invoice date and payment status for aging reports.

Conditional Formatting

To enhance visual clarity and highlight critical inventory conditions:

• Stock Alerts: If Current Stock ≤ Reorder Level, cell background turns red with yellow text.
• Sales Performance: High-selling items (Top 10%) are highlighted in green; slow movers in gray.
• Invoice Status: "Paid" invoices appear in green; "Overdue" (after 30 days) in red.
• Dates: Invoices issued more than 7 days ago but not paid are flagged with a yellow highlight.
