Quarterly Invoice Billing

If you prefer to receive an invoice rather than pay by credit card, we can bill in advance each calendar quarter. Invoices will be sent January 1, April 1, July 1 and October 1. The first invoice will be sent on the first day of the next quarter and will include pro-rated fees for the current quarter as well as the fees for the next quarter. Subsequent invoices will be sent on the first day of the quarter and will include fees for the quarter.

USD 500.00 Minimum
If your quarterly billing amount is less than $500.00, you will be billed the minimum of $500.00. This minimum only applies to invoice billing.
