JordanStephens Hey there,
Tomas is currently away so I'll jump in the conversation.
That's not quite right - Oberlo does not order products from the supplier.
Here's how the whole process works: when a customer places an order in your Shopify store and you receive money to your payment gateway account (PayPal for example), you then have to use your personal credit card and purchase an item for your customer from the supplier, to be shipped directly to your customer.
You'll then need to fulfill that order and this article explains the process in detail: https://help.oberlo.com/orders/fulfilling-orders/how-to-fulfill-orders-using-oberlo
Let us know if you need further clarification!
