The use of the Taulia Vendor Portal is by invitation from your customer.  You have either received an email with an invitation link that will take you to a registration screen or you have received a letter in the mail with a invitation code to use when you get to the registration screen. You will then be asked a series of questions (if your customer requires to) that only you and your buyer would know. Please have access to information on the business you have done with your buyer before you register so you are able to answer these security questions.
