I found a really cool options for managing finance in Align. One of them is Cash Flow from Epic's Finance tab, but unfortunately I failed to enter negative numbers. I tried both "-" end "( )" symbols.
From finance perspective negative cash flow is absolutely normal.
@Arseny Korotaev Great question and use case. From my research it looks like you confirmed that there is not a way to add a negative number to this field. I did not see any details about formatting in help and could not see any bugs or requests in our support system.
I'll ask product management directly to confirm.
In the meantime, I would submit a support case to get this change into our system.
