NOTICE: Due to the increased cost of processing Credit Cards, January 1st, 2026 we will begin to charge a 4% service fee for Credit Card payments through our online portal. If you wish to use a Visa or Mastercard endorsed Debit Card, you may do so, but a 4% fee will be included in the transaction. We do not take plain non-endorsed debit cards. These fee's divert valuable costs away from making improvement's to our service and equipment. Through our portal we provide ACH payments in which will not be charged a fee. This will require you to provide a checking or savings account in our portal to be debited for invoices generated. If you have any further questions about this change, please contact our office at 810-336-3000 or e-mail us at office@cdsmich.com. Please note that our online portal goes through stringent security protocols that keep your data safe, including PCI, CISSP, SOX and other security standards.

NOTICE: Our Contact Forms are not working, our IT is currently looking into the situation and will update as soon as possible.
