Figure 4.2 — The Purchase Order form. Drawing to be produced after the UI/UX pass: annotated capture of the purchase order form naming the supplier and currency header, the quote-validity snapshot, an order line, and the totals block.
The mirror of the sales order (§3.6), with the buyer-side differences:
- Code — the order number (PO-…), the reference you quote back to the supplier on every delivery and invoice query.
- Supplier — choosing one sets the document's currency, fills the exchange rate from the stored table, and stamps the quote validity below.
- Date and Required Date — when you order, and when you need it; the gap between required and received is the supplier's lead time the cockpit measures.
- Valid until — read-only: the quote-validity snapshot, set at creation from the supplier's quote validity days. On a foreign-currency order this is the date their prices stop being committed to you. It moves only through Extend validity or Re-price — deliberately.
- Currency and Exchange rate — the order's money, defaulting from the supplier; the rate frozen onto the order exactly as in Sales, blank rather than invented where no stored rate exists.
- Branch and Department — where your company tracks them, defaulting from you.
- Narrative — the order's own notes: delivery instructions, references, the story.
The Order Lines repeat per product: Product (its expected price arriving from your purchase price and cost records, Chapter 6), UOM, Warehouse — where these goods will be received into — Quantity, Unit Price (in the order's currency; the agreed cost the receipt will expect), and computed Ext. Amount and VAT per line. Order Totals — Subtotal, VAT, Order Total — are the value of the commitment.
