What to Track in Your Beer Inventory: A Complete Data Guide

Essential Metrics Every Collector Needs

These seven metrics are non-negotiable. Every superbuy spreadsheet should include them, regardless of collection size.

• Product Name: The full name including brewery and style. This is your primary identifier.
• Quantity: How many units you own. Updates after every purchase and sale.
• Unit Cost: The purchase price per unit. This is the foundation of all profit calculations.
• Shipping Cost: Delivery fees per order. Track this separately from product cost for accurate margin analysis.
• Total Investment: Quantity times unit cost plus shipping. This tells you how much money is tied up in inventory.
• Status: Available, Reserved, Sold, or Pending. This prevents double-selling and overcommitting.
• Supplier: Where you bought it. This helps you identify your best sources and negotiate better terms.

Optional Metrics for Advanced Users

These metrics add value but are not required for beginners. Add them when you have a specific need.

Metrics That Waste Time

Not every data point is useful. Some create work without delivering value. Avoid these common traps.

• Packaging color: Unless you are a graphic designer, this does not affect value or inventory.
• Bottle weight: Shipping companies handle this. You do not need to track it.
• Exact minute of purchase: The date is enough. The minute adds no analytical value.
• Seller mood: Subjective data that cannot be analyzed. Skip it.
• Weather on purchase day: Interesting but irrelevant for inventory management.

How to Prioritize Your Tracking

Start with the essential seven metrics. Run your spreadsheet for one month. Then ask yourself: what question do I wish I could answer? Add the metric that answers that question. Repeat this process monthly.

This incremental approach prevents bloat. A spreadsheet with fifty columns is overwhelming. A spreadsheet with ten well-chosen columns is powerful. The goal is clarity, not completeness.
