We use an empty group to hide hundreds of inventory items we use on one job as well.  It is messy, and cannot be undone, or added later.  I also means if we want a printed copy of the inventory items on an invoice for ourselves we have to take a screenshot.  I cannot imagine other contractors don't have this problem and that Quick Books doesn't have a option to "not print" or "hide" inventory items from and invoice.  This is our single biggest problem in QB, especially when we want our techs to be able to use IFSM to create invoices in the field - they cannot edit the group in that platform.

In any case, when we use the empty group option, we cannot figure out how to include billable items.  They show up outside of the empty group even if we have our cursor inside of the group.  I have tried adding them, then copying and pasting each line into the empty group, but then those items are not hidden on the invoice.  The best I can do is use the "Print billable items as one group" feature, but then I end up with 2 line items on the invoice - one for the empty group that I created, and one for the billable items.  It looks silly.

We can't be the only contractors that want to hide hundreds of inventory parts we use on a job.
