is there a reason my Invoices don't have a link to the Sales Order they SHOULD be attached to?

I have seen broken links when the users change items in any of the linked transactions. Otherwise, no idea 🤔

so a "good" invoice would have the Sales order on the Invoice Form somewhere?

Yep

you can create a stand alone invoice that means no SO for it. Same broken link happens between PO and vendor bill when user chnages the items

Created from field

yeah and I'm not seeing that... I JUST RECENTLY started having them create WOs from SOs. Would that be a big factor I'm guessing?

If not Sales Order is created, the inventory is deducted in the Invoice itself, as opposed in the Item Fulfillment that a SO needs.

I can look the PO number field ID up and it shows me the linked transactions. The President of our company is heavily involved in all aspects and was just asking why he couldn't backtrack from a invoice to the Sales Order and I thought it was a good question

You can create a Saved Search of Invoices, with the Created From field. In that way you can get a very general view of how many of your invoices are direct, as opposed to created from a sales order.

I will probably go that route temporarily, this isn't going to be a constant thing but I would like to get it figured out to show up on the invoices, especially if it should just be doing it natively

If you use inventory items, you can clearly see the inventory accounts in the G/L impact of the direct invoices, meaning you are not using sales order > fulfillment > invoice

I don't look at any of that but I'll talk it over with the bossman
