How do I pay by credit card?

Addgene accepts VISA, MasterCard, & American Express during the checkout process online. Here's what you need to know:

  • Your credit card will not be charged until after your order has shipped from Addgene, and we will email a receipt to the order contact automatically.
  • You may see a "pending" or "processing" transaction in your account as soon as you complete the checkout process. This is how credit card companies hold funds in your account to prevent them from being used for other purchases. Addgene has not received any money if the transaction still shows as "pending", "processing", or some similar designation.
  • Please note that Addgene can only accept credit card information through the secure payment gateway on our website. If you have received an unpaid invoice from Addgene and would like to pay it by credit card, please email us at, referencing the invoice number.  In our reply, we will provide you a secure link for you to access our payment gateway so that you can submit your card's details directly into our system.
