  • Credit Card Payments

MDS Associates allows our customers to place orders online without the potential for exposing valuable credit card data on the Internet. Follow these three (3) quick steps:

  1. Place an order online at https://www.mdsassociates.com/
  2. Receive an automatically generated copy of your sales order via e-mail  
  3. Arrange for credit card payment - we will phone you, or you can call us.

Credit card fraud is a serious matter that shouldn't be taken lightly. For this reason, MDS Associates does NOT require credit cards to submit orders on-line. Instead, we touch base with you to answer any questions, confirm order details and take credit card information. That info is directly entered into our payment processing system, eliminating the transmission and storage of digital copies of your sensitive personal and financial information.

In the event we are unable to make these arrangements with you, we may close an order after three (3) business days. Please feel to contact us with any questions regarding this business model or to request our federal I.D. number.

MDS Associates accepts Visa, Discover, MasterCard & American Express and we do not charge your credit card until your items have shipped.

Your credit card will be "Pre-Authorized" once your order is placed and confirmed. The “Pre-Authorization” process may show up on your account but is NOT a charge; however, it will verify that your card is not fraudulent.

If you have a back order, this dollar amount is deducted off the first-generation invoice and will be run when the back order arrives and ships. Customers will receive receipts of sale by e-mail.

We reserve the right to refuse processing or shipping of any order based on the information we obtain such as the billing and shipping addresses, amount of goods ordered, contact information etc. For private/residential purchases, we may require a copy of your driver’s license to verify credit card information. 

If your shipping and billing addresses are different, we will need to complete these three (3) steps to prevent delays:

  1. - Confirm we have the CORRECT billing address associated with your credit card.
  2. - Confirm we have CORRECT Card Verification Number.
  3. - At our discretion, obtain the Issuing Bank Phone Number on back of card*

*For security reasons, we may need the phone number to verify your information with your credit card company for alternate ship to address which are not on record with your credit card company. The phone number you just entered must be the number your credit card issuer would use to call you. Giving an incorrect billing phone number will delay the shipment of your order. Your order will be delayed up to 4 business days for verification if your information is incorrect.

  • Credit Term Payments

Customers with established accounts can order on-line and pay with 30-day credit terms (NET30).

New customers can request credit terms by filling out and submitting the credit application that can be found here. However, this process can take 2-4 weeks+, so we recommend placing initial orders with a credit card while we confirm and review the application.

  • Sales Tax

Sales tax for orders shipped to New York State will be added to your sub-total including applicable shipping. Tax exempt organizations need to fax or email MDS a tax exempt certificate. 

Please always feel welcome to call (800) 274-4637 or e-mail [email protected] to place your order or have your questions answered. Thank you for considering MDS, we look forward to meeting you!
