Wayne County Supplier Portal
Current and awarded suppliers will be invited to register in the new Wayne County Supplier Portal. Through the Supplier Portal, suppliers can:
- Update company profiles
- Submit invoices electronically
- Track payment status in real time
What Hasn’t Changed:
Wayne County will continue to post solicitations and receive proposals through BidNet Direct (MITN) at https://www.bidnetdirect.com/mitn/county-of-wayne.
Notice: Very soon, all invoices for Purchase Order payments will be required to be submitted by the supplier through the portal. If you have a current PO with Wayne County, but have not yet received an invitation to Supplier Portal, please complete the survey at the following Link: Supplier Portal Contact Survey (For PO Vendors Only)
