The sort of already happens. Over here, businesses don't have to pay sales tax (VAT) on the goods and services they buy, because when they finally sell the item or service to a customer, the sales tax is charged in full.

So while a business doesn't pay sales on the fuel they need to deliver their goods to me, it gets paid in the end because the cost of the fuel is included in the price I pay and the sales tax is levied on the whole purchase price.

(It is a little more complicated than that. Don't sue me.)
