identifier

Unique text or a unique image on an invoice that Tungsten AP Essentials uses to identify a supplier. Invoices with the same identifier are from the same supplier.

An example of an identifier is a bank account number. If invoices from a supplier always contain the same unique bank account number, you can use this to identify the supplier.

Another example is a logo. If invoices from a supplier always include the same unique logo, you can use this to identify the supplier.
