- Raise the order. Pick the supplier; the form brings their currency, the stored exchange rate, and your quote validity snapshot (§4.6). Lines take their expected prices from your purchase price and cost records (Chapter 6).
- Approve it. Approval commits the company: the order's value is now an open commitment the cockpit counts, and the supplier may be told to proceed. Approve and post remain separate permissions (1.5).
- Receive the goods. The goods receipt is raised from the order and records what actually arrived, into which warehouse, at the order's cost — plus lot details where the product is lot-tracked, and the landed-cost grid (§4.5). Posting the receipt moves the stock in. A short delivery leaves the balance open on the order; it is never quietly forgotten.
- Enter the supplier's invoice. The purchase invoice is raised from the receipts it covers, so its lines arrive already matched to what came in. This is the three-way match: order said it, receipt proved it, invoice charges it. With GRNI on, posting the invoice clears the liability the receipt recorded (§4.5); differences between the receipt's figures and the invoice's do not vanish — they post openly to their own variance accounts, price difference and exchange difference kept separate.
- Pay it. Payments are allocated against the invoice until it is settled (§4.5).
The order closes when everything on it has been received and invoiced, or by hand when the remainder will never come.
