Figure 13.3 — The Marketplace Order form. Drawing to be produced after the UI/UX pass: annotated capture of the order form naming the seller and receiving account, a line drawn from a listing, the resolved commission rule, and the gross–commission–net totals.
- Code — the order number (MKO-…), from the number sequence.
- Date — the day the sale completed.
- Currency — the currency the channel sold in. Every amount on the order — its lines, its totals, what the seller is owed on it — is denominated in this currency. It defaults to your functional currency; choose another whenever the channel settled in one. The picker is always there: an order's currency is a fact of the channel it arrived through, not an optional extra.
- Exchange rate — functional currency per one unit of the order's currency, offered from the rate table for the order's date and adjustable before you save. It is frozen on the order when the order is saved and never moves afterwards: the ledger posting, the governed readings and the seller's payout position all value this order at this rate, however the market moves later. An order in a foreign currency cannot post until a rate stands on it or in the table — the posting refuses, naming the currency, rather than guessing. Orders recorded before order currencies existed carry no currency and read as functional throughout.
- Buyer Name — who bought, as a name. Buyers have no record in your books and owe you nothing on it.
- Seller — the marketplace seller whose goods sold; choosing them resolves the commission rule below.
- Received Into (Bank/Cash) — the account the money landed in; debited with the gross when the order posts. There is no posting without one.
- Commission Rule — shown, never typed: the rule resolved for this seller (§13.5), whose rate prices the order.
The Order Lines repeat per item sold: Listing (optional — choosing one fills the description and unit price from the listing), Description (what was sold, in words), Quantity and Unit Price, and the Line Total they compute to.
The Totals are computed and read-only, all three: Gross Amount (the lines' sum), Commission Amount (gross at the rule's rate) and Net Amount (the seller payable) — each denominated in the order's currency, like every amount on the form. Nothing in the totals can be typed over — if a total looks wrong, the lines or the rule are where the truth is. When the order posts, the ledger entry is written in functional currency at the frozen rate: the bank leg is what actually arrived, valued by the bank account's own rate, the payable and the commission at the order's rate, and any difference between the two is booked as realised exchange gain or loss — never silently absorbed.
