SCBO and SCPro: South Carolina Vendor Registration (2026)

What SCBO is

South Carolina Business Opportunities (SCBO) is the State's online advertising publication for public solicitations, published at scbo.sc.gov by the State Fiscal Accountability Authority's Division of Procurement Services. It covers goods, services, information technology, and construction. SCBO states that state agencies must advertise solicitations there when estimated values exceed specified thresholds, while cities, counties, and school districts may advertise voluntarily, so SCBO is not a complete list of every local bid in the state.

SCBO is an advertising publication, not a vendor account. Its online edition states that a vendor must be registered with the State of South Carolina to bid on government solicitations, and it links to the State's vendor search and registration portal. You need both: a current State vendor registration and a routine for reading SCBO.

For construction, the Office of State Engineer (OSE) Manual for Planning and Execution of State Permanent Improvements (2023 Edition) states that agencies must publish its required advertisements in SCBO, that SCBO is published daily Monday through Friday, and that advertised projects stay online until the bid date or submittal deadline. For a wider view of public bid sources, see our guide to finding government construction bids.

What changes in November 2026: SCEIS to SCPro

South Carolina is replacing its SCEIS vendor registration system with SCPro, a new web-based procurement system. SC Procurement Services publishes these dates on its supplier registration page:

• Through October 25, 2026, at 11:59 PM: the SCEIS Vendor Registration Portal stays open for profile updates and modifications.
• October 26 through November 9, 2026: a system freeze and data migration. The State says no registration updates can be processed by the State or by suppliers during the freeze.
• November 9, 2026: SCPro Release 1 is scheduled to go live, covering supplier accounts, solicitations, and contract management.

If you miss the October 25 deadline, the State says you must wait until SCPro goes live to request registration updates or create a new profile. From November 9, Procurement Services states, suppliers register, update their information, and respond to new solicitations in SCPro. The SCPro FAQ adds that solicitations will not be migrated from the old SRM system, and that SCPro will integrate with SCBO and email suppliers registered under the commodity code used on a solicitation. Launch dates can move, so verify current steps on the official portal.

Step 1 - Check whether your company is already registered

Before creating anything new, check whether your company already has a State of South Carolina vendor record. SCBO's online edition links to the State's vendor search, and Procurement Services advises searching the first word of the company name followed by an asterisk.

Procurement Services says it is migrating current vendor information into SCPro, and the State's SCPro registration guide says a new request is rejected if, for example, the email matches an active SCPro user or the company is already fully registered. Ask internally first; someone in accounting may have registered the firm years ago. The official pages reviewed for this guide do not explain how a migrated SCEIS vendor first signs in to SCPro, so verify on the official portal or with Procurement Services.

Step 2 - Open the SCPro Public Supplier Portal and start New Supplier Registration

Open the SCPro Public Supplier Portal at scpro.sc.gov and choose New Supplier Registration. The State's SCPro quick reference guide lists the opening steps: click New Supplier Registration, complete the CAPTCHA, click Submit, and select your Registration Type, which defaults to US Registration. Procurement Services calls this tier Initial Registration and states that accessing the form does not require login credentials.

Before November 9, 2026, the State's vendor resources page still points new vendors to the SCEIS registration portal, while the SCPro FAQ says that portal is open for profile updates and modifications only until October 25. If you are inside that window, confirm which path applies on the official registration page.

Step 3 - Enter entity, address, and contact details

Enter your entity, address, and contact details exactly as they appear in your tax and business records. The SCPro quick reference guide says fields marked with a red asterisk are mandatory. For US Registration, the entity section asks for your Recipient Type/1099 Classification, your Legal Name exactly as it appears on your W-8 or W-9, your Tax ID Number type (Federal Employer ID Number or Social Security Number) and the number itself, any Doing Business As (DBA) name, and your Federal SAM Unique Entity Identifier (UEI) if you have one. If you also bid federal work, our SAM.gov registration guide covers that side.

The guide states that the address entered is where payments are sent, and that if both a PO Box and a street address are listed later, the State defaults to the PO Box. The contact section asks for name, email, company phone number (formatted ###-###-####), position, and a password. That email becomes your SCPro login, and this first user is automatically designated as an Administrator. Use a monitored company mailbox, not a personal address that leaves when an estimator does.

Step 4 - Choose counties served and commodity codes

Choose the counties you serve and the commodity codes that match the work you want to bid. The SCPro guide says you indicate whether you intend to respond to solicitations, receive purchase orders, or be awarded a contract; enter the South Carolina counties you serve, or choose South Carolina for statewide service; and select the commodities you provide.

Commodity codes drive notifications. The guide says SCPro automatically sends solicitation notifications based on the commodity codes being procured, and that to be notified by email, your organization must have indicated it can provide the code included in the procurement. Codes can be updated on your profile later. Pick codes for the scopes you actually price, such as sitework, roofing, mechanical, or electrical; too few and you miss notices, too many and the team ignores them. The official pages reviewed for this guide do not name the code system SCPro uses, so verify the code list on the official portal.

Finish with the CAPTCHA and click Register. The guide states that you will receive an email notification about your initial registration request.

Step 5 - Complete Full Registration before award

Complete Full Registration so the State can award you a contract and pay you. Procurement Services states that Initial Registration (Bidder) lets you search and bid on active sourcing projects, while Full Registration (Supplier) is required before the State can award contracts, issue purchase orders, or process payments.

The SCPro quick reference guide describes the process:

• Log in with the email and password from initial registration, and accept the General Terms of Use the first time.
• Under General Info, open Company Profile and fill in Email, Company Phone Number, Type of Industry, and NAICS Code if they are blank.
• On the Contacts tab, assign at least one Supplier Admin and one Supplier Finance user. They can be the same person.
• On the Documents and Certs tab, upload an IRS document such as a W-9. The guide states that one is required to submit.
• Click Submit. The State reviews the request, and you are notified when it is approved or rejected.

SCPro training materials add that the State runs a TIN check, and the guide states that MWBE certifications must be approved by the State before that status shows on your profile. Do not wait for an award to start.

Step 6 - Keep contacts, codes, and documents current

Keep your SCPro profile current so notices reach the right people. SCPro training materials list a Sourcing Contact role as the primary contact for bid opportunities, and say changes to company information go through a change request that the State approves. Procurement Services states that Supplier Finance is the only role authorized to manage bank account details.

Review codes, contacts, and the W-9 whenever an estimator, project manager, or bookkeeper leaves. Procurement Services also offers free live supplier webinars on registering, responding to sourcing projects, and managing contracts in SCPro; check the registration page for the schedule.

How to find and submit a bid through SCBO

Start with SCBO's online edition at scbo.sc.gov, which lets you browse advertisements by category and date or use the advertisement search. Categories include Construction, Minor Construction ($10,000 - $100,000), Architectural/Engineering, and Maintenance/Repair. Because SCBO publishes each business day, check the construction categories daily.

Construction ads list fields such as Project Name, Agency/Owner, Project Number, Bid/Submittal Date & Time, Project Delivery Method, Construction Cost Range, Agency Project Coordinator, and Documents May Be Obtained From. That last field varies: some ads point to an agency website, some to a portal such as BidNet Direct or OpenGov, and some to an email address. Our guides to BidNet Direct, OpenGov Procurement, and Bonfire cover those kinds of portals.

For state construction, the OSE Manual (2023 Edition) sets the rules agencies follow. Key points for bidders:

• Construction contracts with a construction budget over $100,000 must be advertised in SCBO, and the SCBO advertisement is the official invitation for construction bids.
• For construction over $10,000 but less than $100,000, an agency may request written quotes from at least three qualified sources or post notice in SCBO's Minor Construction section.
• Pre-bid conferences must be advertised in SCBO, and missing a mandatory pre-bid conference or site visit is a listed reason for rejection.
• Addenda must be issued at least five business days before bid opening. A bid that fails to acknowledge all addenda must be rejected unless it shows in some other way that they were received.
• Bids must arrive at the address in the invitation and published in SCBO before the public bid opening. Delivering a bid to the agency by fax is cause for rejection.
• Each bid over $100,000 must include a bid bond or certified cashier's check of at least five percent of the base bid, with the agency named as obligee. Personal checks and letters of credit are not acceptable.
• Construction contracts over $50,000 require a performance bond and a labor and material payment bond for the full contract amount.
• Citing SC Code Section 40-11-260, the Manual notes that general and mechanical contractors must be licensed for projects valued at $10,000 or more, and agencies verify licenses for the bidder and its listed subcontractors.

For central purchasing solicitations for goods, services, and IT, the State's submitting-offers page currently links to the SCEIS SRM vendor portal and makes each bidder responsible for confirming that the response status shows Submitted. From November 9, 2026, suppliers respond to new solicitations in SCPro. The official pages reviewed for this guide do not say whether every construction solicitation will run through SCPro, so follow the submission method in each SCBO ad and its bid documents.

How ConstructionBids.ai helps

ConstructionBids.ai brings public construction bids from thousands of portals into one searchable feed with deadline alerts, which can sit alongside an SCBO routine. South Carolina contractors should keep reading SCBO directly for state procurement notices, and should register and submit through the State's official systems.

Because local governments may advertise in SCBO voluntarily, a complete South Carolina routine usually includes city, county, and school district portals too. One feed filtered to your trades and geography cuts the time spent checking them by hand. ConstructionBids.ai plans are $59, $79, and $99 a month, with a 7-day trial of Command.
