Choosing the Currency on a Grain Invoice
The invoice currency decides who carries the conversion. Pick it in the contract, then use it on every page.
A grain contract is a quantity and a price, and the price is incomplete without a currency. Dollars, the buyer's local money, or a third currency each put the conversion risk on someone. That choice is not a footnote to the exchange-rate story. Exchange rates matter to exporters because the value of a foreign receipt can move, a point made at https://goodsandgrain.trade/exchange-rates-grain-exports. This note is about which unit you write on the invoice, and what happens when the pages disagree.
One currency, named in the contract
Write the currency in the price clause, not in a later email. If the bid was discussed in dollars, the contract should say dollars. A buyer who thinks in another currency can still sign a dollar price. What they cannot do fairly is discover the currency when the invoice arrives. Match the commercial invoice to the contract. The invoice's job is described at https://goodsandgrain.trade/grain-commercial-invoice-contents.
Spell the name in words if a symbol is ambiguous. A symbol that two currencies share is how a clerk pays the wrong unit. The code your bank uses is clearer than a symbol alone.
Who lives with the move
If you invoice in the currency you already owe your lender and your suppliers, you have less conversion risk and the buyer has more. If you invoice in the buyer's currency, you will convert, or your bank will, on a day that may not be the day you priced the cargo. Neither choice is generous. It is an assignment of a risk. Price the assignment. A buyer who demands their local currency and also demands the cheapest dollar-equivalent is asking you to carry the move for nothing.
Advances and final invoices must use the same currency unless a conversion rule is written. Otherwise the credit for the advance will not match the wire. Advances are discussed at https://goodsandgrain.trade/advance-payment-in-grain-sales.
Banks, credits, and the day of conversion
A letter of credit pays in the currency it names. If that currency is not the one on your invoice, you have a discrepancy, not a clever hedge. Credits are strict about this, as explained at https://goodsandgrain.trade/letter-of-credit-grain-sale. Ask the bank which currencies it will pay you without a special arrangement. A currency you cannot receive is not a commercial victory.
If a conversion is required, say who converts and which day's rate, or accept that the bank's own practice will decide. Silence is a small argument waiting for a large cargo.
Costs that arrive in another unit
Freight, inspection, and demurrage may be billed in a different currency from the grain. That is normal and messy. Keep those invoices distinct so you do not subtract a freight bill in one unit from a grain total in another and call it a net price. Your own books should show the grain currency and the cost currency side by side. Blending them in a single cell is how a profitable cargo looks poor, or the reverse.
Also resist changing currency between the proforma and the commercial invoice. Those two documents are compared at https://goodsandgrain.trade/proforma-versus-commercial-invoice. A silent switch looks like a changed price.
Write it once and paste it
Choose the currency when you price. Paste it onto the contract, the invoice, the credit, and the wire instruction. If a counterparty asks to switch after the vessel is fixed, treat it as a new price, because the risk moved. This is practical contract hygiene, not foreign-exchange advice. For a large exposure, ask your banker how the receipt will actually arrive before you agree the unit.
Frequently asked questions
Is a dollar price and a local-currency price the same sale?
Only on the day you convert, and only at the rate you actually get. They are different risks until then.
Can I invoice in one currency and receive another?
Only with a written conversion rule and a bank that will do it. Do not assume the rate or the date.
What if the symbol is unclear?
Name the currency in words and use the code your bank uses. Symbols are how the wrong money gets sent.
