Hi, In order to print item receipts / GRN documents, do you have to install the Advanced Localization Features bundle, or is there another way?

You don't necessarily need the Advanced Localization Features bundle. It depends on your NetSuite setup and the type of Item Receipt/GRN document you want to generate. In many cases, a custom Advanced PDF/HTML template or transaction form can achieve the same result without installing the bundle. I've worked with NetSuite custom forms and document templates and can help you determine the best approach for your setup.
