Vision, Mission & Objective

Providing competitively priced, quality products by direct global sourcing. AOS also offer products and services from one of our well-established partners. AOS was founded with focus on high quality, punctuality, transparency and trust.

AOS’ effort and commitment was noticed early on by the industry, and activity increased even when the downturn hit. During a time where most companies closed offices in Asia Pacific, AOS continued to grow providing much needed support in a supply-chain vacuum.

AOS offshore remain committed to client’s initiatives
aimed at reducing cost and improving up-time.

AOS’ success continue to be recognised, and AOS is on the AVL with a growing number of clients. We have also signed agreements with several OEM companies. The agreements allow our partners to have a presence in Asia Pacific while saving cost on offices and head count. This cost saving is an important part of keeping our prices down.

AOS would not have enjoyed this success without our strong local knowledge and partners. Our local network is extensive, and we support local businesses.
