I suspect this is a regular customisation request, but it would be very useful to have a limited number of additional fields added to tables where there are cards (e.g. Customers, Vendors, Items, Sales Orders, Sales Quotes, Purchase Orders, etc.) that can be used by admins for business specific purposes and for these additional fields to be renamed. Ideally you'd be able to define the data type, but a small number of predefined fields of the main data types would be a good compromise. These fields should be exposed on the associated form templates so that they can be used for documents/reports. I see this in most other ERP systems and it is frustrating not to have it in a Microsoft product, which should be feature leading.
