These are some of the Carr Communications projects that included e-commerce or other online payment / donations functionality.

• Democratic Professionals Council. Members can RSVP online for DPC events and pay for the event fee via PayPal or credit card. The website calculates the total price for the member and his or her guests, provides email receipts, and logs transactions to a database so organizers know who has and has not paid.
• Online donations via PayPal for multiple campaign websites, including those of Bryan Miller for State Representative and Coral Springs Mayor Scott J. Brook. The website prompts donors to provide information that is legally required for campaign finance reporting, such as employer and occupation.
• CID International, Designer Templates, Decorator Training Institute, and Ron Renner Gallery – retooled the shipping cart and sales reporting functions of these existing e-commerce websites. Automated functions such as assigning user passwords for online training courses.
