you're confusing a lot of things here. company b llc will have it's sales run under company a llc, and cease operating as a separate entity these two are contradicting each other. if b llc ceases to exist - it is not going to have it's sales run under a llc, since there will be no sales to run for a non-existent company. what happens is that you merge b llc into a llc, and then convert a llc into s corp. so you're cancelling the ein for b llc, you're cancelling the ein for a llc - because both entities cease to exist. you then create a ein for a corp, which is the converted a llc, and you create a dba where a corp dba b shop. you then go to the bank and open the account for a corp dba b shop with the ein you just created for a corp. get a better accountant. before you convert to s-corp.
