Looking for ways to bulk update the Exemption Certificate No. field on the customer record for Avalara. When we went live, we didn't have certificates updated so we set that field to EXEMPT for all customers. Now we need to remove it so we can use the certificate information stored in Avalara. Its not updatable through CSV import or Mass Update. I also can't see the AvaTax tab or that field on the form. We need to also make sure no one with edit permissions can update that field. Help!
