For invoices denominated in a fiat currency which payment is received in the same currency at the end of the process, the bookkeeping of the transaction is the same as usual.
The accountant does not need to be informed about using blockchain technology, as the amount received in the bank account matches the amount of the invoice.
Invoices paid in cryptocurrencies are different. Go to your Request Finance dashboard, export your invoices as a CSV or download them individually as PDFs and send them to your accountant. Your accountant will then have all of the information needed to finalize your accounting.
Your accountant will manage these invoices in a similar way as a payment in a foreign currency, including exchange rate gains and losses, and additionally might also have to book capital gains.
