What do PO, PI, QT, and IQ represent in Patisco? What are the differences?

All four are trading documents with differences in who issues them and which stage they are used in: - IQ Inquiry: Buyer inquires pricing from seller. Located in left sidebar [Inquiry]. - QT Quotation: Seller's quotation to buyer. Located in left sidebar [Quotation Management]. - PO Purchase Order: Buyer's order to seller. Located in left sidebar [PO]. - PI Proforma Invoice: Seller's order confirmation and billing basis. Online payments are also processed through PI. Located in left sidebar [Proforma Invoice (PI)]. Common workflow is inquiry → quotation → buyer issues PO → seller issues PI. When you receive a customer's PO, you can click [Convert to Proforma Invoice] on that document to directly create your PI. Inquiry, quotation, and PO are not linked together. Each document type has two lists: "Sent" (documents you issued) and "Received" (documents the other party issued). Both parties have their own copy. Editing your copy does not directly change the other party's; they only see the latest version when you click [Send].
