Annex Fulfillment

Annex Fulfillment is the rebirth of a decade old fulfillment program. In 2014 we purchased a building expanding our fulfillment & warehousing operations. In an effort for growth, we rebranded under Annex Fulfillment as our Annex building serves us as both as additional fulfillment and overstock capacity.

Annex Fulfillment has added technologies for streamlined fulfillment that OSI historically did not have. We can integrate with your website which automates data entry, and makes it possible to typically ship orders same business day if placed before 1pm. Although you are still working directly with OSI, you can find more about our fulfillment offerings on Annex Fulfillment's Website.
