BSO was founded on the guiding principle, that customer service counts. We customize our programs to the clients needs. Where other IT and suppliers treat you as just another number, we are here to provide you with white glove service every step of the way. Our idea is simple the customer comes first.

Our logo is a modernized Yin and Yang symbol. Why? Because we embody the thought that contrary forces don't need to be mutually exclusive. They can be complementary. In the IT sourcing world, other companies may sacrifice speed for quality. Or accuracy for price. We believe that you don't have to.

Our goal is to deliver on all of the below at the highest levels of customer service possible.

Speed
Quality
Accuracy
Price

They all matter to us, because they all matter to you.
