Credit Card

Machine Science accepts major credit cards for purchase. All credit card transactions are processed by Authorize.Net.

IMPORTANT NOTE: Authorize.net validates all credit card transactions by ensuring that the customer's shipping address matches the billing address for the card. If you experience any difficulty processing your order, please check to ensure that these two addresses are the same.

Invoice

For the convenience of schools, universities, and other organizations that do not typically make credit card purchases, Machine Science will accept payment by check from pre-approved institutions. An invoice will be included with your order, and payment is due upon receipt. Note that this payment option is made available only to pre-approved customers. Please contact Machine Science at 617-354-7171 for more details.
