Oh no! Someone got an invoice sent out after payment. The question is where is the checkbox to turn this off/on? As it happens there are several places that would be causing people to get invoices sent to them.
E commerce -> Settings -> Orders
E commerce Setup -> Recipts -> Orders
If the overall settings above are set to send an invoice the below settings will not override
This means if you turn the invoice off below and it is on in one of the above settings, an invoice will still go out.
If you are creating an order VIA action set
If you are creating an order VIA campaign sequence make sure the options in the screenshot below are not selected.
