How to handle the odd transaction in USD, despite only having a GBP bank account

[Dr. David Kirkby (Kirkby Microwave Ltd)]

My company sells products in GBP, but a particular customer wants to pay in
USD, so I quoted him a price in USD which he is going to pay into the
company bank account. The bank account is GBP, so the bank (RBS) will
convert the USD to GBP, at some interest rate, and with some fees.

How should this be recorded?
