Add invoice to new order merchant notification in PS 8.1

[stevell]

Hello

Has anyone found a solution to adding a copy of the invoice pdf to the new order merchant notification. A copy is sent with the customer notification but not with the merchant notification. 

There are modules for PS 1.6 and 1.7 but not 8.1. 

I have previously used the module from LogicalIT in PS 1.7 but it's not compatible with 8.1 and I have emailed them a couple of times over the last 2 years if they are going to make it 8.1 compatible but they don't reply.

Regards

Steve
