Why is there a $1 charge on my account?

When adding a card to our software, our third party payment processor will send over a request to your issuing bank for a $1 authorization. They do that to verify that the card is issued and the bank will allow your charge to be authorized. 

The important thing to remember here is that the $1 authorization is not a charge. 

It will disappear from your statement within a few business days.
