Why Your Order History is a Goldmine
Most users simply check their spreadsheet for current parcel status and costs. However, maintaining a personal log or copying data from completed orders allows you to build a private database. This database helps you identify patterns in shipping costs, product quality, and seller behavior that are impossible to see when looking at orders in isolation.

- Total Declared Value:
- Parcel Weight (Actual vs. Volumetric):
- Final Shipping Cost:
- Parcel Weight (Actual vs. Volumetric):
By creating a simple average, you can establish a baseline cost per gram or per item category (e.g., "shoes," "hoodies"). For your next haul, you can estimate the total shipping cost before

Create a simple rating system in your personal log: This transforms your buying decisions from being based on random forum posts to being driven by your own documented experience. With several parcels' worth of data, you can answer strategic questions: Start today: Create a new Google Sheets or Excel file.
