It is a requirement for a bill to have a bill number entered - and this is a nuisance because I have to then take the time to enter data that I generally don't need to capture.

If want to see full details of the bill, I can open the PDF attachment of the original bill that I will have uploaded to Books when creating the bill.

I know that it is mandatory currently, and I understand the reason/benefit of having a bill number field, what I'm asking is that this field simply be made optional.

In the interest of helping users enter their data as quickly as possible, I propose that Books doesn't force users to enter data that they may not want to enter.
