Case Study: Constant Contact achieves scalable, reliable overnight billing with AppDirect's jBilling

Constant Contact - Customer Case Study

Constant Contact, a leading provider of online marketing tools for small businesses and nonprofits with over 500,000 customers worldwide, faced a growing billing problem as it expanded its products and customer base. Its legacy billing system couldn’t scale or complete full bill runs within the required time, and limited access to code made troubleshooting and customization difficult. The company needed a robust, flexible solution to handle complex billing scenarios and support rapid growth.

Constant Contact selected jBilling, keeping existing business rules while replacing underlying code and using jBilling’s plug-in architecture for customization. The new system was implemented quickly by a small team and now completes full overnight billing runs reliably, supports sales tax and multi-currency options, and allows changes to payment processors. With improved performance, scalability, and responsive vendor support, jBilling met Constant Contact’s evolving billing needs.
