Vendor checks are paid on a net 30 basis.  Invoices should be submitted to the specific department for processing.

All vendors must fill out a W9 form and submit it to the department they will be doing work for. The department will forward it to Finance for set up in the system.  If you are a LLC (limited liability company) please indicate if you are a single member, partnership or corporation LLC.  If a single member, please include your name and social security number.  We prefer you use our substitute W9 form so that we also have your contact information in our system.
