    Register as a Commonwealth Supplier

    Overview

    Before bidding on Commonwealth contracts, you must register through the PA Supplier Portal. The portal is where you will set up your supplier account and manage your company's profile. 

    Registration takes less than 15 minutes and gives you instant access to Commonwealth procurement opportunities. Once registered, you will be able to:

    • Submit electronic bids for contracts
    • Monitor invoice and payment status
    • Access invoice remittance information
    • Update your company’s information online at any time

    Before you start

    • Use a desktop/laptop with Microsoft Edge or Google Chrome. Do not use a phone or tablet for best results.
    • Have your IRS-issued nine-digit Employer Identification Number (EIN) ready. A Social Security number will not work for business registration.
    • Monitor your inbox for emails from a pa.gov address. Be sure to check your spam folder, too.
