As far as my recollection goes, there are two customizable fields to the entry form in Quickbooks: 1) class and 2) location/project. The other four fields are your standard 1) vendor, 2) GL account, and 3) Client 4) date. Hence, in total, there are six separate filters for running modified reports.
You may use the class or project field for identifying each transaction as a phase. The class field should be used if you expect that separate line items will apply to a different phase as the project field applies to the whole transaction.
I personally used the project field in cases where I wanted the transaction to be reflected on the balance sheet report. If this is the case for your purposes, the phases will appear on the balance sheet as a capitalized amount. But this doesn’t seem to be the case in your example.
