Found out from HW's North America support team that SERP on the Order Browse has a function that allows you to mark the Sales Order as "invoiced". This works great and saves the client from having to close the order which for many reports will not include the order. So "Set Order as invoiced" works great.

Would be nice if this is added to the Operation Menu on the Orders themselves. Currently you run your Invoicable Orders report and then you have to open up the order browse and search for the order to set it.

Would be less work for the client if you can use the hot link to the order on the report, run the function for the Order Browse and close and recalculate your report. Lots smoother and appealing to the SERP UX.

Great option all the same!
