Most of the content in a PI (Proforma Invoice) comes from an already-confirmed quotation: line items, quantities, unit prices, payment terms, and shipping terms. If this information already exists in the system, you can generate the PI directly from the quotation without the sales team re-entering everything. During conversion, the system applies the quotation terms, and flags any price discrepancies for review before finalizing. Besides saving time, this prevents errors from manual re-entry and ensures all terms are accurately transferred. If a single PI needs to be split into multiple shipments, each batch can be processed separately, and commercial invoices and packing lists can be generated from the same data without creating a separate document.
