How to Conduct Your Yearly Review: A Step-by-Step Guide

Step 1: Data Entry & Consistency

Ensure every purchase from the past year is logged in the spreadsheet. Each entry should include item name, price, seller, shipping cost, QC result (GL/RL), and any refund amount. Consistent logging is the foundation of accurate analysis.

Step 2: Calculate Total Spending

Use the spreadsheet's SUM functions to total all cost columns. Separate item costsshipping costs

Step 3: Analyze Refund Trends

Filter or create a pivot table to sort entries by refund status. Ask yourself: Were refunds clustered with a specific seller or item type? Calculating the total refunded amount as a percentage of total spending reveals your financial recovery rate.

Step 4: Assess QC Success Rates

Count the number of items you marked "Green Light" (GL) versus "Red Light" (RL). Divide the GL count by the total number of QC'd items. A high success rate indicates effective seller selection and QC processes.

Step 5: Draw Conclusions & Adjust

Combine these insights. For example: "Although my total spending was $X, my refund rate was high for Seller Y, but my overall QC success improved in the second half of the year." Use this to make informed decisions about which sellers to trust and where to allocate your budget next year.
