The gap between making this at home and selling it is mostly documentation and a date, because the product itself often needs no change at all.

Fix the oil, not just the flavor

An infused oil tastes of what you put in it and ages according to what it was made from. Changing the base oil changes the shelf life, the clouding behavior in a cold kitchen and the flavor underneath the infusion. Fix the base oil and its supplier in the specification, not only the botanical.

Write the infusion method down, in full

If you acidify, the method is the safety control and it has to be written as a procedure rather than remembered as a practice: what solution, what ratio, how long, what is done with it afterwards. An undocumented control is one you cannot show you followed, which is the same position as not having one.

Then the bottle, and then the label

Net quantity comes from the bottle and the fill. Whether the bottle blocks light changes the shelf life you can honestly print. Both of those have to settle before artwork, and both move while a product is being developed.

The date is a claim

A best-before date on an oil is a statement about a product whose main enemy is time, so it is the claim most likely to be tested by reality. Hold stock back from your own batches, store it the way a customer would, and taste it at the date you printed. That is the only honest basis for the number.

What stops being optional

A batch code on every bottle, tied to the oil lot it came from.
The supplier lot of the bulk oil, recorded, so a problem upstream is traceable downstream.
The infusion method and the date it was carried out.
A recorded acid strength for a vinegar, with the method.

Decide filtered or unfiltered, and commit

It changes the appearance, how soon the product clouds in a cold kitchen, and what claims sit comfortably on the label. It is also the kind of decision that drifts batch to batch if nobody writes it down, which produces a product that looks different each time for no reason the buyer can see.
