Regarding adding another client to your profile as a vendor.
This cannot be done from the CondoWorks vendor portal.
If you have received an email from a client asking you to register for CondoWorks, you do not have to register again if you already have an account used for other clients. If you are invited by an additional client, simply click the link in the blue box at the top of the registration screen to add the client to your profile.
If you have not received such an email, please contact the management company to add the vendor to the client. Once they do this, you will receive an email with details on submitting invoices to that client.
