What does the setting do
This is the master switch. It means: as soon as an order comes in from eCom, Junipeer immediately creates and books an invoice in the ERP. No waiting for fulfillment/delivery.
This is a deviation from the model flow of invoicing, which happens at the fulfilment, not at order create stage.
With this setting checked, the invoice is booked the moment the order exists, which means capture and invoice creation are decoupled — the booked invoice can exist in ERP before the payment is actually captured.
Flows
Enabling this setting will make invoice creation dependent to the Order Flow. Deactivating it will make the invoice creation dependent to the Transform Order to Invoice flow.
