Use Order Date for Invoices During Orders to Invoices

If you would like to use the Order Date as the Invoice Date when creating new invoices with Income -> Orders -> Fulfillment Order -> Orders -> Invoices, turn on the setting Admin -> Billing -> Company Options -> Invoicing & Ordering ->Fulfillment Orders -> Invoice Using Order Date Rather Than Current Date. Click Save when done. When this setting is off, the current date will be used as the Invoice Date for new invoices.
