Hi firstresponse,
Thank you for your post.
Sorry to hear about having difficulty in adding a supplier name to an item. You can set up suppliers and items at any time before you begin entering a bill (using the Contact menu or the item's link in the purchases menu) or while creating it (using the + Create supplier and + create items list options). We have a Help Article: Enter a bill, quote, or order and Adding a supplier that has detailed information that you can use as a guide. Also, after doing the process, if the suppliers' names still do not appear, we recommend doing the basic troubleshooting like clearing the cache, clearing them fixes certain problems and helps your device run optimally.
If still need further assistance with this or if you have other questions or concerns, please contact us again or create a new post. We are happy to help.
