Question

How would I acquire on the internet Company marketing services? What companies are there in the marketplace?

Answer 1

Right now, when a customer purchases something online and the retailer does not have a physical presence in the customer’s state, the merchant does not have to charge sales tax on the transaction. It’s up to the consumer to pay sales tax on all goods purchased online directly to their government at the end of the year. This is something that very few people do.
