I have a checking account and a credit card under my LLC.

Me and my significant other are currently located in NJ but dream of making this move happen on the island.

So dream of equity and forget about cashflow,... its just a myth.* These are just my personal beliefs based on my experience.

Typically a credit card balance does not need to be paid off to include the expense on the current year return. 

How many bank/credit cards?

The last post is correct, we are required to have our license classification and clearly displayed on our trucks, business cards and any other advertising.

Everyone has their own dream and criteria.

It's seamless, makes tracking revenue and expenses very easily, provides me with bank account options for all of my properties as well as virtual credit cards AND a hefty interest rate on savings.

When you return an item, if it's on a credit card, you can just enter a credit card transaction for a refund and apply it to a COGS account. 

I have been successful for other clients negotiating a get out of debt free card for the DIL.
