Users can setup alternative names for their products. The alternative names will be shown on documents PDF. 

To setup alternative name, go to the product info, enter name(s) you like into the field and save.
​

Additionally, you can save alternative name(s) for customers or suppliers. The app will automatically apply the product default alternative name(s) for those customers/suppliers in the relevant documents.

In case you change your mind, the alternative name is optional so you can choose to have them displayed or not.
