Hi Monique,

When you click OK to save the order, you are presented with a small screen that has Order and Invoice options at the top, and fields indicating what the Order/Invoice/Credit numbers will be (or AUTO if the program assigns the numbers). If things have been set up correctly, the Order option that is at the top left of the window is editable.

As you indicated, the Order option is available. But if it is not selected, then indeed an Invoice will still be generated. You need to click that Order option to not generate an invoice.
