Order number VS Invoice number

Hi guys!

Woocommerce put by default an order number to all orders, including those who are cancelled. I needed all my “real” new orders (only those that are pending orders – paid) to be truly sequential.

I found a way to do it with your plugin by just checking the sending PDF “attach to” for only “new orders/admin email”. Once this done, no “invoice” number is set beside a cancelled order in Woocommerce. Which is nice.

BUT..

Woocommerce still creates an “order number” for a cancelled order. So it can look like this in my admin order page:

Order #2020 – Pending – Invoice #2019
Order #2019 – Pending – Invoice #2018
Order #2018 – Cancelled
Order #2017 – Pending – Invoice #2017

How can I just use YOUR plugin invoice number and not the Woocommcerce order number that is set by default?

Thanks!
