KAKOBUY Guide: How to Track SKU Performance Over Time

2026-03-09

Leverage Data for Smarter Purchasing Decisions

In the fast-paced world of e-commerce and retail, intuition alone isn't enough. Successful inventory management hinges on data-driven decisions. At KAKOBUY, we recommend using a centralized performance tracking spreadsheet

The Three Core Metrics to Monitor

Your tracking spreadsheet should, at minimum, include the following columns for each SKU, updated weekly or monthly:

1. Product Popularity (Sales Velocity)

  • What to Track:
  • Why It Matters:
  • Spreadsheet Column Example:Units_Sold_MTD, Sales_Trend_↑→↓

2. Return & Refund Rate

  • What to Track:
  • Why It Matters:
  • Spreadsheet Column Example:Return_Rate_%, Top_Return_Cause

3. Shipping & Fulfillment Delays

  • What to Track:
  • Why It Matters:
  • Spreadsheet Column Example:Avg_Lead_Time_Days, Delay_Alert

Building Your Tracking Spreadsheet

A basic table structure can be implemented in Excel, Google Sheets, or any data tool:

SKU Product Name Period Units Sold Return Rate Avg. Lead Time Performance Notes Action Item
KB-2024-TEE Premium Cotton Tee May-2024 320 2.1% 3 days Strong sales, low returns. Increase reorder quantity.
KB-2024-GADGET Multi-Function Gadget May-2024 95 8.5% 12 days High returns due to complexity; supplier delays. Negotiate with supplier, update user manual.

Turning Data into Smarter Purchasing Decisions

Regularly review your spreadsheet to guide your actions:

For Top-Performing SKUs

Increase purchase volumes, consider strategic price adjustments, and ensure ample stock to avoid stockouts.

For High-Return SKUs

Investigate root causes. Improve product photos/descriptions, inspect quality with suppliers, or consider discontinuing the item.

For Delay-Prone SKUs

Diversify suppliers, adjust lead times in your system, or communicate longer delivery estimates to customers.
