Do I really need a barcode?

I wanna sell good lower priced products to a local store that is doing well, and they can sell it and they can make profit but I don't want any money from their sales I just wanna make profit from selling my product and that's it I don't want to be involved in anything else.

I don't want to be involved in anything else.

Barcodes are too expensive
And it will slash my profit margins

Is this even a thing or possible?
Can't they just put their own barcodes?
It's local and not a chain so they can just make their own for free for inventory management purposes

Am I being stupid
