Fashion dropshipping supplier test: delivery, fit and real costs

1. Define the delivery route

Write down the supplier warehouse, destination country, shipping service and product variant. A website language is not a delivery market: an English shop might serve several countries. Check the exact route in the supplier's current terms. Confirm the return address and who pays each cost before ordering; support for deliveries does not establish support for returns.

2. Order and inspect a sample

Use the service you intend to offer customers. Save the product listing and size chart as they appeared when you ordered. Measure the garment flat in centimetres, name the measurement points, and compare them with the chart. Photograph the seams, fabric, labels and packaging in ordinary light. Record the actual difference instead of calling an item simply good or bad.

3. Keep evidence for every claim

Record payment, first carrier acceptance scan and delivery dates separately. A created tracking label is not proof of dispatch. Keep the invoice, tracking events, measurement photos and support replies together. Remove names, addresses and order identifiers before publishing evidence. One order describes one product on one route; it cannot establish an average delivery time or a supplier-wide defect rate.

4. Calculate the order contribution

Enter revenue after discounts, excluding tax collected for authorities, plus any shipping paid by the customer. Use one currency for every amount. Include supplier shipping, payment and conversion fees, estimated unrecovered return costs, and an allocation for store subscriptions or other overhead. The starting values are an invented example: 40 − 16 − 7 − 2 − 3 − 2 − 8 = 2. Replace every assumption with your own costs.

5. Decide what is ready to launch

Pause a product if its measurements conflict with the listing, costs leave no room for your plan, or delivery and returns remain unclear. Correct the listing or resolve the issue, then repeat the relevant check. Publish only the route, dates, costs and observations you can evidence. Repeat orders are needed before making reliability claims. This is our test method and worksheet; no supplier sample results have been collected for this guide yet.
