Main Settings for WooCommerce
In the Invoices menu, select Settings and then go to the WooCommerce tab.
Sequential Order Numbers
Out-of-the-box, WooCommerce does not have sequential order numbers. We made activating subsequent order numbers possible by selecting this option. In new stores, order numbers begin from 1. In stores with orders, numbers continue from the last order number.
Date of sale on the invoice
Set which date will be the date of sale on the invoice. You have to choose the order date or order completed date ( status change on completed ).
Select if you want to show variation attributes next to the product name. When enabled, the example name of the product on the invoice will be: T-shirt (Size: M, Color: green).
Select if you do not want to automatically issue invoices for free orders.
Free line items (PRO)
Select if you do not want free items, such as free products or free shipping, listed on the invoice.
Select if you want to show the order number on the invoice.
Select if you want to show the SKU number on the invoice.
Currency Exchange Table (PRO)
