Is Customer and Is Supplier — control which document types a party can be used on: a Sales Invoice requires the party be a customer, a Purchase Order requires the party be a supplier.

Party Fields
The Outstanding panel
Every party’s edit page shows a read-only Outstanding panel — total amount this party owes you (receivable, if they’re a customer) and total you owe them (payable, if they’re a supplier). This updates automatically as invoices and payments are recorded; you never edit it directly.Create a Party
