Blues Man, within a 4.55% conventional sales tax system, the final purchaser within the chain of transactions is likely to be paying substantial embedded sales taxes in addition to the explicitly stated 4.55% sales tax. The aggregate total of those embedded unaccounted sales taxes differs for different products.
Within conventional sales tax systems, enterprises within chains of sales transactions are required to forward 100% of their collected sales taxes to the government along with their paperwork.
Enterprise's compliance paperwork for conventional or VAT are of similar complexity, (which is much simpler than most, (if not all) income tax systems).
Within a VAT system, enterprises are required to forward only the DIFFERENCES between the sales taxes they paid and those they collected, which expedites their their cash-flows. I've often been confronted by critical cash flow problems. I suppose that's a particularly typical challenge among small businesses.

Value-Added Tax (VAT) Definition (investopedia.com) , doesn't attribute great importance to the fact, unlike the older conventional sales tax systems, a 4.55% VAT system would increase products prices within every link of a commercial transaction chain by no more than 4.55%; there are no embedded additional sales taxes within a VAT system of sales taxes.
