What is OASIS?

wvOASIS Guide

This web page gives some general information related to the procurement module of the State of West Virginia's Enterprise Resource Planning (ERP) system, known as wvOASIS.  The wvOASIS system is administered by the Enterprise Resource Planning Board and more information about that agency can be found at wvOASIS.gov.

West Virginia Purchasing Bulletin

The West Virginia Purchasing Bulletin is now available only through the Vendor Self-Service portal in wvOASIS.

When viewing the West Virginia Purchasing Bulletin through the Vendor Self-Service (VSS) portal at wvOASIS.gov, vendors are now able to view solicitations currently out for bid by West Virginia state agencies and be able to search for bid opportunities in the portal using key words and other criteria, such as by department, by newly-published solicitations, et cetera.  Paid, registered vendors with the Purchasing Division will also receive notifications of bid opportunities based on the commodities they select during the registration process.  They will also be notified if a state buyer adds their wvOASIS vendor/customer number to a solicitation, even if they are not registered for the commodity code contained in the solicitation.

There is no limit on new bidding opportunities a vendor can view.  Please continue to visit this special webpage created by the West Virginia Purchasing Division for updated information on the procurement module of wvOASIS.  You are also encouraged to visit the wvOASIS official website at wvOASIS.gov for more details on this project.


Create an Account in Vendor Self Service

The Vendor Self-Service Portal (VSS) allows vendors to conduct business with the State of West Virginia.  Many state procurement functions such as the West Virginia Purchasing Bulletin and vendor registration are administered in wvOASIS through the VSS portal.

Vendors can utilize the VSS to manage their registration accounts and take advantage of its many benefits including:

- Setting up user accounts for its employees based on the type of access they need to have
- Receiving e-mailed bid alerts and notifications based on the commodity codes the vendor selects
- Keeping the company’s contact information, including mail and e-mail addresses, up-to-date
- Reviewing business opportunities, awarded contracts, and payment status online

Since the system went live on July 8, 2014, bid opportunities for the vendor community appear through the VSS portal.  Vendors are strongly encouraged to activate their vendor accounts, update registration information, and set up employee accounts at their earliest convenience.  For more information on setting up your company in the Vendor Self-Service system, you may consult the AMS Advantage® Vendor Self Service Registration Quick Start Guide.

When you are ready to activate your VSS account, please visit wvOASIS.gov and click the Vendor Self-Service link to begin.


Responding to a Solicitation

Vendors may respond to solicitations online through the Vendor Self-Service portal at wvOASIS.gov.  In the case of solicitations expected to exceed $25,000 going through the formal purchasing process with the West Virginia Purchasing Division, vendors may alternatively respond in hard copy format and submit responses to the Purchasing Division offices prior to the bid-opening date and time.

Vendors wanting to learn more about how to do business with the State of West Virginia are encouraged to read the West Virginia Vendor Procurement Guide, which serves as an introductory resource for businesses interested in the procurement process with state government entities.


What is wvOASIS?

wvOASIS is the state's Enterprise Resource Planning (ERP) system.  It has modernized the state's business processes through automation, fully or partially replacing approximately 100 of the state's former business applications.

An ERP system is a comprehensive suite of software modules that provide for statewide administrative functions, including financial management, procurement, asset management, personnel administration, payroll, time reporting, and benefits administration.

The purpose of this system is to facilitate the flow of information between all business functions within state government and manage more effectively the relationships to our partners, such as the vendor community.  These integrated software modules play a vital role in operating a modern approach to the state government procurement process and enhances tracking, reporting, and provides a greater transparency to state government functions.

One new user-friendly function of wvOASIS is the Vendor Self-Service (VSS) feature.  Many of the existing state procurement functions, such as the West Virginia Purchasing Bulletin and vendor registration, are now being administered in wvOASIS through the VSS portal.  The VSS portal allows vendors to:

- View commodities and services currently out for bid that your company may be able to supply
- Receive solicitation notifications by e-mail based on commodities and services in which your company has expressed interest at the time of registration
- Improve future business opportunities with the State of West Virginia
- Review awarded contracts
- Perform inquiries pertaining to awards
- View payment status online and submit invoices online
- Update your company contact information, including mail and e-mail addresses
- Set up user accounts for employees based on the type of access your business requests
