Sheet Structure

The template comprises four interconnected sheets to ensure modular data handling while enabling seamless dashboard updates:

• Supply Inventory – Primary data entry sheet containing all supply records.
• Purchase Orders – Tracks procurement history, vendors, costs, and delivery dates.
• Dashboards – Interactive visualization hub with charts, KPIs, and summary tables.
• Settings & References – Contains static lookup tables (e.g., categories, units of measure) and threshold values for alerts.

Table Structures & Column Definitions

The Supply Inventory table is structured with the following columns:

Formulas Required

The template employs advanced Excel formulas to automate decision-making:

• Total Value: =[@[Current Stock]] * [@Unit Cost] — Calculates total inventory value per item.
• Status Indicator: As above, dynamically updates based on stock levels and thresholds.
• Usage Rate (Monthly): =SUMIFS(Purchase Orders!Quantity, Purchase Orders!Item ID, [@Item ID], Purchase Orders!Date, ">="&EOMONTH(TODAY(),-12))/12 — Calculates 12-month average consumption.
• Days Since Last Reorder: =TODAY()-[@[Last Reorder Date]] — Helps identify stale stock or delayed replenishment.
• Projected Days of Supply: =[Current Stock]/[Usage Rate] — Predicts how long current stock will last.
• Dashboard Totals: SUMIF, COUNTIFS, and SUMPRODUCT functions aggregate values across categories for KPI cards.

Conditional Formatting

Visual cues enhance usability:

• Status Column: Red fill if “Reorder Needed,” orange if “Low,” green if “Adequate.”
• Total Value Column: Color scale from light yellow to dark red based on value magnitude.
• Projected Days of Supply: If below 15 days, text turns bold and red with warning icon.
• Expiry Dates (in Notes): If date is within 30 days, cell highlights in yellow.

User Instructions

1. Begin by populating the Settings & References sheet with your category list and vendor names.
2. Enter each supply item in the Supply Inventory sheet. Ensure Item ID is unique.
3. Update Current Stock after each usage or replenishment.
4. Add new purchase orders in the Purchase Orders sheet using the dropdown for Item ID to auto-populate data.
5. The Dashboards sheet updates automatically—no manual input required there. Refresh PivotTables if needed (Data > Refresh All).
6. Review weekly: Use the Dashboard to identify items approaching reorder point and flag budget overruns.
7. Do not delete rows in Supply Inventory. To archive an item, mark it as “Discontinued” in the Status column.

Recommended Charts & Dashboard Elements

The Dashboards sheet features interactive components:

• Inventory Health Gauge Chart: Shows overall % of items below threshold.
• Bar Chart: Top 10 High-Value Items: Highlights capital-intensive supplies.
• Pie Chart: Supply Category Distribution (by Value): Reveals where budget is allocated (e.g., Reagents = 65%).
• Line Chart: Monthly Usage Trends: Tracks consumption over time to forecast future demand.
• Summary Cards: Real-time KPIs: Total Inventory Value, Items Needing Reorder, Avg. Lead Time (days), Total Spent This Quarter.
• Drill-Down Filters: Slicers for Category, Supplier, and Status allow users to segment views dynamically.

This template is not merely a static list—it is an intelligent system embedded with business logic tailored for Research Management. By combining the granular control of a Supply List with the strategic clarity of a Dashboard View, it empowers researchers and administrators to prevent costly delays, reduce waste, and maintain continuous project momentum. With minimal training, teams can transition from reactive inventory management to proactive resource planning.
