Lawyer's Treasure's case in the article shows a gross margin exceeding 20%, indicating that even with small-quantity courier, if your quotation structure is designed properly, margin space still exists. The core logic is: small-quantity courier costs should be reflected in your quotation, not absorbed by you. The "prepaid courier" model typically means taxes and freight are already included in the shipping price—the retailer pays an all-in-delivered price, making it clear for them to calculate profit, and for you to completely pass through costs. In practice, the small-quantity trial stage initially isn't about making money on volume anyway; it's about building market track record. Once distributors contact you proactively because you have evidence, bulk shipment logistics costs naturally fall, and your overall margin structure improves too.
