A fractional CFO's constraint is hours. Each client needs a report, a forecast and a conversation, and the preparation often takes longer than the advice. Scale up the client list and preparation expands to fill the week. The forecast agent prepares a rolling cash view and drafts month-end commentary for each client. You read, correct and add the context only you have. The advice, and the judgement behind it, stay yours.
Because the same agents run for every client, your workflow becomes repeatable. A new client is connected, the forecast is built from their data and the first commentary draft arrives without a blank page. You decide what the client sees, and you still lead every conversation about what the numbers mean.
Drafts are useful only if they sound like you and reflect what you know. A little setup time per client pays back, because the same pattern then repeats for every pack that follows. Do this for your first two clients, then reuse it.
Forecasts depend on the books beneath them. If a client's bookkeeping is behind, the forecast will be weaker, so the bookkeeping agent can be a sensible first step. The output is a projection, not a promise, and it is not financial advice. Measure the result by how many clients receive a pack on time and how much preparation time shrinks.
