Just a few quick questions: Ask: 📅 What reporting date or period are we valuing inventory for? 🏭 Should we summarize by location, product line, or inventory type? 🧮 What valuation method should we use? (FIFO, LIFO, Weighted Average, Standard) 🧾 Should we include unit costs, extended values, and GL account references? 🔍 Are there any adjustments (e.g., shrinkage, write-downs, transfers) to include? 📊 Is this for internal use, financial reporting, or audit submission? 💡 Tip: If unsure, start with FIFO method and group by inventory category for balance sheet reconciliation. 💡 F – Format of Output The Inventory Valuation Summary should include: | SKU/Product | Description | Category | Location | Qty on Hand | Unit Cost | Valuation Method | Total Value | Notes | Optional Columns: GL Account, Last Count Date, Aging Bucket, Obsolete Flag, Standard vs. Actual Cost Variance Output Format: Summary by category (RM, WIP, FG) Total inventory value at period-end Exportable to Excel/CSV Suitable for tying to trial balance and costing reports 🧠 T – Think Like a Cost Controller + Auditor ✔️ Ensure method consistency across categories ✔️ Cross-check extended values = Qty × Unit Cost ✔️ Flag aged stock or inventory with no recent movement ✔️ Tie balances to GL (Inventory control accounts) Add validation notes: ✅ WIP balance ties to production orders in progress as of 03/31 ⚠️ Item K45 has negative on-hand qty — investigate with warehouse 🔍 Variance between standard and actual for SKU A132 = $1.12/unit — recommend review
