What this record is, and what it is not

A benefit realization ledger reconciled to a general ledger needs the customer’s actual baseline figures and account structure. more

The measurement window ran FY25 Q2, eight weeks, shortened over a sample of 23,852. That sample size is on the page because a baseline drawn from twelve cases and one drawn from forty thousand are not the same instrument, and averaging them into a single confidence figure would hide which one you are looking at.

3 of 5 cash lines resting on this baseline carry a journal reference. A benefit line with no journal reference has not touched the general ledger, so it is shown as claimed rather than counted as realized cash.
