I am just starting out using Magenta and know very little about the cart only that it seems to work very well, so making it work with Joomla! was the project.
I found Yireo and bought not only the bridge but other add-ons they did and their installation service.
Within 3 days not only had they installed it and got Joomla! and Magenta working with each other but offered advice on parts of my Joomla! setup that I had missed!
Excellent value for money and first class service, well done!
