More and more people have recently consulted our X-ray exposure hand switches. When the customer tells us his specific needs, including model, length, quantity and customer related information, we will make a formal invoice (PI) for the customer to wait for the customer’s payment.
So what is PI? It is the meaning of a formal invoice.
This is the initial sales list sent to the buyer before shipping or delivering the goods. Invoices usually describe the items purchased and other important information, such as shipping weight and shipping costs.
