About Electronic Ordering

Electronic controlled substance orders are placed using a software program that has been approved for CSOS. Typically, this software is available through a wholesaler and may be implemented into their ordering Web site. This software includes functionality to digitally sign the purchase order using the purchaser's CSOS digital certificate issued by DEA. A CSOS Certificate may be installed into multiple software programs and may also be transferred to multiple ordering computers.
