Use Fulfillment Data for Product Selection and Replenishment Decisions

Fulfillment data is the most honest operating signal. Link sales, returns, turnover and shipping share, and decision quality clearly rises.

1. Sales + turnover leads to replenishment qty

Look at the last 30 days' sales and turnover days; compute safety stock = daily sales x turnover days x coefficient - do not replenish by feel.

2. Return rate leads to selection warning

If a SKU's return rate exceeds the category average, investigate the cause before deciding whether to keep pushing - avoid selling more at a bigger loss.

3. Shipping share leads to pricing

For items with too-high shipping share of price, either raise price, change packaging or drop them - to keep the profit structure healthier.
