Payment Information

Beginning in January 2023, all future invoices will have our new billing address below as we have migrated to a banking lock box to ensure 24/7 security & staffing.

While our Lawrence, Kansas location will remain, we kindly ask that all payments be mailed to the new Dallas, Texas address below. All email addresses, phone numbers, & Maintenance Center info will remain the same. If you are paying via ACH or credit cards, nothing has changed. This only impacts clients that are paying by check.
