Assalaamu alaykum, the following is the simple solution for dropshipping which can work:
1.Sell as Salam agreement with customer. This means you take payment in full from customer to supply an item you currently don’t own.
2.Thereafter, you go and purchase item from supplier in a normal transaction by paying.
3.You take responsibility for shipping so the Shariah requirement for possession is fulfilled.
- You take responsibility for Item to be sent directly to customer.
