Invoice and package slip notre generated on pending

Hello Jean,
It’s not recommended to make the invoice number follow the order number! I have done a small writeup in the documentation, along with a solution:
Why is the invoice number different from the order number?

If you still want the numbers to match, there’s a solution for that further down that page:
But I want the invoice to have the same number as the order!

Note that no email is sent for pending payment orders, if you want to force invoice number creation, check this post: https://www.ads-software.com/support/topic/generate-invoice-as-soon-as-order-received/#post-5475990

Hope that helps!
