Prompt payment of NorthStar Engineering's invoices is an essential aspect of the overall consideration required for providing service to our clients.

Typically, we require that our clients make an initial payment (retainer) upon execution of our professional service agreements. This retainer is held and applied against the final invoice. Accounts are billed during the third week of each month for services performed in the previous month, are due upon presentation and are considered past due if not paid prior to the next billing date.

For our client's convenience, we accept the following forms of payment:

• credit card (Visa, Mastercard, AMEX, Discover)

            - download credit card charge authorization form

• personal check
• money order
• cashier's check
• cash (in person only)

The credit card charge authorization form allows you to either have your invoice automatically paid each month (option #1) or to make a one-time payment (option #2). Should you decide to select option #1, you will still receive a hard copy statement with a summary of charges and payments made each month.
