Have you ever run a business ? You collect a % of your sales for state sales tax. You then report and send that money to the state on a monthly basis. If they think you are keeping those taxes they audit you.
What is different than what most businesses do now ?
two onerous sales tax collections are not better than one onerous sales tax collection. DOUBLE the montly work.
Of course this assuemes the business is not currently in a service business and does not have to collect ANY sales tax.
