Common questions aboutour dropshipping workflow

Answers sourced directly from our partner onboarding and support conversations.

How do I know if a product is in stock before I list it?

Our inventory API syncs every 15 minutes. You can connect your store (Shopify, WooCommerce, etc.) to see real-time stock levels, including buffer for in-transit orders.

What happens if a customer returns an item?

We handle returns for defective or incorrect items at no extra cost. Return shipping is covered for orders under our standard policy. For buyer's remorse, we offer a restocking fee model – details in your partnership agreement.

Can I order samples before committing to a full drop?

Absolutely. Sample orders are shipped via express courier (3–5 business days). We deduct the sample cost from your first full order of that product.

What are the typical shipping times to the US and EU?

Economy 7–14 days, standard 5–8 days, and express 2–4 days depending on the product category and warehouse origin. You can filter by speed in our product catalog.

Do you offer branded packaging or custom inserts?

We offer private-label packing for partners with monthly order volumes above 500 units. Reach out to your account manager for lead times and design support.
