When Transaction Advisors acquired two related websites, we helped integrate those sites into their existing Drupal 7 infrastructure, providing responsive theming, subscription access, and a single administrative interface for all three sites.
Integrating the two new sites with the existing Transaction Advisors Drupal 7 installation and database using the Drupal Domain Access module allowed for each site to have its own domain name and theme while providing a single administrative interface.
We extended the Transaction Advisors theme to the SatelliteFinance and TelecomFinance sites in a responsive way so that they worked on all devices. For easy subscription management and access to paywall restricted content, we integrated Stripe via a custom module. The Drupal Feeds module allowed us to import all content from the two legacy sites before going live.
