Before you can submit a bid or proposal through South Carolina Enterprise Information System (SCEIS), you must be registered as a vendor. If you have not done so, please go here. For assistance with registration or submission of your bid or proposal, please reference the following guides. For additional assistance, call the SCEIS Help Desk at (803)-896-0001. (Note: Please do not contact the procurement officers directly as they do not control the SCEIS system.)
