A portfolio is a collection of companies that were bought, not built, which means they share nothing. Different accounting systems, different charts of accounts, different definitions of the same metric, different close calendars. Every reporting cycle is therefore an integration project performed manually by analysts, and it happens again next month.
The cost is not primarily the analyst time, expensive though that is. It is that the numbers arrive too late in the period to act on, and that the operating partner’s meeting gets consumed by reconciling definitions rather than by discussing what the numbers mean. A variance discussion that begins with "which revenue figure is that" has already lost most of its value.
Standardising the portfolio is the obvious answer and it is not available. Migrating a portfolio company onto a common system is a multi-year programme with a real disruption cost, aimed at a company that may be sold before it completes. Nobody funds it, and they are right not to.
Diligence has the same shape in compressed form. A data room arrives, a small team reads it under time pressure, and the risk is not what they find but what they do not have time to read. The work is document comprehension at volume against a deadline, which is precisely the shape of task where machine assistance is most useful and most defensible.
And the reporting demands are increasing rather than stabilising. Limited partners ask for more, more frequently, in more standardised formats, and the operating model that produced quarterly numbers by hand does not extend to it.
