How to become a new vendor with sei
Welcome to the Self Enhancement, Inc. New Vendor Portal. Here, you can securely submit the documentation required to work with SEI. This portal provides an electronic alternative to emailing personally identifiable information.
It is strongly encouraged that you use the ‘Send me a copy of my responses’ button at the bottom of the form to confirm your submission, but at minimum we ask that, if you are unsure that your submission was received, please connect with your SEI contact directly to confirm.
Required Vendor Documentation
W-9: Request for Taxpayer Identification Number (TIN) and Certification – This document tells SEI your name and/or the name of your business (if separate/distinct), your tax classification, your address, and your taxpayer Identification number (SSN OR EIN).
TAX CLASSIFICATION – If you check ‘LLC’ in Box 3a., you MUST also choose a tax classification to the right of the check box.
ADDRESS – Please provide the address where you would like your tax documents mailed. If you need your payment sent to a different address please clarify that with your primary SEI contact.
TIN NOTE – Please only provide one of either your social security number or your employer identification number. The number provided is the number we will report to the IRS for any income received as required.
Certificate of Insurance (COI) – When entering into a contract with SEI, you will need to provide documentation of any business insurance coverage you have. Your insurance carrier should be able to provide a COI on request.
ACH Enrollment Form (Optional but Recommended) – This form is an SEI specific form that authorizes us to deposit your payments directly into your bank account/Cashapp/Venmo.
ACH BACKUP DOCUMENT – In addition to the enrollment form, we’ll need a third-party backup document that confirms the account information you list on the enrollment form. We recommend a voided check or a direct deposit confirmation letter from your bank/Cashapp/Venmo, but we can accept any third-party document including screenshots of ‘Account Details’ pages from online banking provided it confirms the full routing and account info you list on the enrollment form.
Background Check Documentation – Individuals whose work includes direct interaction with youth or minors, or who perform work at the Tony Hopson, Sr. Center for Self Enhancement or other SEI sites where youth may be present, are required to provide proof of a current and valid background check.
