Once you have completed the Lulu integration and a customer purchases the product, the order will appear in your Lulu account. The order will appear as unpaid in LuLu unless you have set up your account to be on auto-payment. If you do not set your Lulu account to auto-payment you will need to send funds to your Lulu account each time an order is submitted. Once the order is marked as paid, Lulu will fulfill the order and ship the product to your customer.
JVZoo recommends placing a credit card on file with Lulu to prevent having to manually process and pay for orders. It is also recommended to place a test order to ensure everything is working as expected.
