Invoice of -$37.50
 
The -$37.50 is a credit for the free trial for the first $15K billed ($15K x 0.25% = $37.50). The amount carries over every month. We invoice quarterly, users can find out more about our billing cycle here:

The trial period ends when you consume your credit of $37.50 (ie. bill more than $15K). Once we have a charge pending after your free trial, we will request your credit card information.
