The prospective buyer can pay the purchase price in a different currency. After the sale you will need euros to meet your own obligations, however. The proposal should therefore not be judged solely on an exchange result shown on the internet. The following editorial steps prepare a discussion with the bank and contract advisers. They serve as organisational guidance for Austria and Germany and do not recommend any currency transaction.
Describe the actual proposed performance
Record which amount in which currency is meant and when it is to be paid. Is it a price determined in euros with payment to be processed differently, or is the price obligation itself to be determined differently? This legal classification must be clarified by the responsible adviser for the specific proposal.
Add who would organise an exchange, at which point it is intended and which accounts would be involved. The article does not declare any payment route to be suitable and does not assume any generally permissible form of receipt.
Distinguish reference rate and actual processing
The European Central Bank explicitly publishes its reference rates for information purposes and advises against using them for transactions. [EZB] A displayed exchange figure is therefore not a confirmed offer from your bank for the planned payment in this preparation.
Ask about the actual terms of the intended service provider: offered conversion, relevant time points, possible fees and the treatment of delays. Use concrete answers for this. This article asserts neither a current rate nor a typical fee amount.
Record your own need in your currency
Note which amounts you actually need in euros and at what time. Put outstanding costs and the confirmations required alongside. A hoped-for conversion advantage does not belong in the calculation as money already available.
In the hypothetical case a seller wants to repay a euro loan from the proceeds. The buyer names a foreign currency amount which, according to a first private calculation, seems approximately appropriate. The seller now has the concrete processing examined and asks how timing, the actually offered conversion and costs relate to the available euro amount. He does not replace his open question with the best exchange figure from a search engine.
Assign the uncertainty consciously
For contract advice, in particular the payment currency, the decisive amount, the processing route and possible timing deviations are important. Which side assumes which risk and what security might be sensible is designed individually. The article provides neither an automatic exchange clause nor a recommendation for a forward transaction.
If the consequences cannot be explained to you in an understandable way or the required certainty is lacking, this is an open decision question. A desire for a quick conclusion does not make the unknown conversion more calculable.
Compare complete variants first
Place the examined foreign currency proposal next to a concretely described euro payment route, if this is available. Compare for each the confirmed scope, the costs, the timing requirements and your remaining own need.
This is how you decide on an understandable payment process. The figure on the purchase offer and the amount later available for your plan will not be equated unnoticed.
