Important Notice
Creating a user account in the Region 4 electronic bidding portal does not authorize a vendor to conduct business with Region 4. Vendors must respond to a specific solicitation (“bid”) that undergoes a formal review process and requires approval by the Region 4 Board of Trustees before any business may be conducted.
Vendor Registration
All existing and prospective vendors who wish to respond to a solicitation must register in the IonWave E-Bidding platform. Once registered, vendors will receive email notifications when solicitations are issued related to the product or service categories selected during registration.
Proposal Submissions
- Procurement documents are available exclusively through Region 4’s electronic bidding portal.
- Vendors are responsible for ensuring that Region 4 Procurement has the correct company name, authorized representative(s), and contact information on file in order to receive notices, addenda, or other important updates.
- All proposals must be submitted electronically through the portal by the stated deadline. Faxed or emailed proposals will not be accepted.
- Proposals must be submitted early enough to be received and time-stamped by the system before the due date and time. The portal will not accept late submissions.
- Please note: If a vendor begins responding to a solicitation but does not click “Submit” before the deadline, the proposal will not be considered.
- All proposals must remain valid until the anticipated Board of Trustees meeting date specified in the solicitation and until any and all deviations to proposal submittals are approved by Region 4.
Registration does not guarantee contract award. Formal procurements follow structured evaluation and approval processes.
