As a Guest Supplier, your customers can suggest that you enter your invoices at the SY Portal. 

This tab lets you:

• Collect the additional legal information that must be shown on invoices (based on the country)
• Set default values for some recurring information (such as “for settlement” or “discount”)

The objective is to produce a compliant invoice and avoid your having to enter this information each time you enter an invoice

You can complete this tab when you want, but you must have done so before you enter your first invoice. Otherwise, SY will tell you when you try to enter your first invoice.
