This is a question about US taxes and accounting.
The documentation I've read says that if an estate is run on a cash accounting system, then any income received after the decedent's date of death is income that belongs to the estate and is therefore to be reported with the estate's tax filing. Anything before the date of death is filed with the decedent's last tax return.
Is this also true for a sales transaction where the sale terms were completed on paper prior to the date of death but the actual proceeds were not received until after the decedent passed?
