Sheet Names

• Invoice Entry: The main working sheet where users enter invoice details and manage order items.
• Inventory Ledger: A real-time database of all stocked items, including quantities, costs, reorder levels, and last updated dates.
• Supplier Directory: A reference list of vendors with contact details, lead times, pricing tiers, and preferred ordering terms.
• Dashboard Summary: An analytical overview sheet featuring KPIs such as inventory turnover rate, stock status alerts, total invoice value by month, and low-stock warnings.

Table Structures and Columns

1. Invoice Entry (Main Sheet)

2. Inventory Ledger (Database Sheet)

Formulas Required

• Invoice Entry - Subtotal (I3): =IF(AND(G3<>"", H3<>""), G3*H3, 0)
• Invoice Entry - Tax Amount (K3): =IF(J3<>"", I3*(J3/100), 0)
• Invoice Entry - Total Amount (L3): =I3+K3
• Inventory Ledger - Last Updated Date (H2): Use an auto-update formula based on the date of entry, e.g., via VBA or manual update.
• Invoice Entry - Description (F3): Uses VLOOKUP to pull item name from Inventory Ledger: =VLOOKUP(E3, Inventory_Ledger!A:H, 2, FALSE)
• Deduct Stock Upon Invoice: In the "Inventory Ledger" sheet, use a formula to subtract quantity sold via:

  IF(SUMPRODUCT((Inventory_Ledger!$E$2:$E$100=ItemCode)*(Invoice_Entry!$E:$E=ItemCode))>0,
             [Current Stock] - SUMPRODUCT((Invoice_Entry!$E:$E=ItemCode)*Invoice_Entry!G:G),
             [Current Stock])

  This formula dynamically adjusts the stock level based on all active invoices.

Conditional Formatting

• Low-Stock Alerts: Apply red fill to any row in the Inventory Ledger where Current Stock Level ≤ Reorder Level.
• Pending Orders: Highlight rows with "Reorder Required" status using yellow background when stock is below threshold.
• Total Amounts: Use a gradient scale for the Total Amount column to visually distinguish high-value invoices.
• Invoice Date Validation: If invoice date is in the future, apply bold red text to warn users of incorrect entries.

User Instructions

1. Setup: Begin by populating the Inventory Ledger with all current stock items. Ensure each Item Code is unique and accurately reflects your catalog.
2. Add New Invoices: Navigate to the Invoice Entry. Enter customer details, select an Item Code from the drop-down list, input quantity sold, and let formulas auto-calculate values.
3. Auto-Update Inventory: After saving the invoice, check the Inventory Ledger. Stock levels will automatically decrease based on sold quantities.
4. Order Replenishment: If a low-stock warning appears, consult the Supplier Directory, place a new purchase order, and update inventory after receiving goods via manual entry or bulk import.
5. Analyze Data: Use the Dashboard Summary to view monthly sales trends, top-selling items, and stock turnover rates. Charts auto-update as data changes.
