I've first contacted SystemsManager about 8 years ago. I was looking for some complex customization for my osCommerce online shop at that time. Being able to discuss and do business with someone in Canada, very close to my actual location, was a key factor in chosing SystemsManager.
I've found that they had an understanding of my needs that surpassed all other coders I'd contacted. Service has always been excellent. I would never hesitate referring SystemsManager to anyone in need of osCommerce programming and related services. They are the true experts. Cheers!
