During our bookkeeping, we will see a row of data in a statement that is missing some information about the financial event. We will send you a email about this and ask for a more detailed explanation.
In the email is a link to a page where you respond with your answer.
Our conversation with you is by messenger.
And there is a message ID. Which helps your bookkeeper align your answer with their question.
It is possible you require a discussion to finalize your answer. In this case contact support (refer to message ID), firstname.lastname@example.org
