Hey guys, quick question, I'm testing a customization with SuiteTax, I have enabled it, and set everything up following the check list NetSuite provides, everything is looking good. The taxes are calculated based on my setup. so, I have some generic customers created for integration purposes, I'm creating invoices daily and I want to prevent for this specific customers that the taxes are not calculated since we are already adding the taxes on the line level with a special line item (this is just for the integration purposes), so I was able to create a saved search and add the items that I know we create as part of the integration and then add them to the Nexus > non-taxability rules. I run a few tests and it is working, however, I have some scenarios in which a script create items on the fly that I might need to try to automatically include them on the non-taxabilty rules, hence I was looking at the certificates exemptions and I'm wondering if there is any other way to make a customer exemption of taxes? These customers are not real customers, so I'm not sure if a fake certificate setup on the SuiteTax would work since I read that it validates it from an external service. Do you have any ideas how to handle this?
