The Second Engagement: What Happens After the 90-Day Number
After a 90-Day Number engagement, three honest paths: run it yourself, a light cadence, or quarterly reviews. A Sydney virtual CFO on the post-project…
Most CFO engagements are designed so you cannot leave; the retainer rolls on by default and the value of leaving is never made clear. A 90-Day Number engagement is designed the opposite way: it ends, you hold a finished deliverable, and what happens next is a genuine choice with more than one correct answer. This page sets out the honest paths after day 90, including the one where you need nothing further, which is stated with the same respect as the ones where you engage again.

The engagement is built to end with you holding something real. On the last day you have the named deliverable, the 13-week cashflow, the financial model, the unit economics build, the board pack, whichever you chose, plus a working session that hands it over so you can run it yourself. It is yours: the model, the method, and the understanding of how it works, not a dependency that only functions while someone is retained.
That is the deliberate design, and it shapes everything about what comes next. Because you hold a finished, usable artefact rather than a relationship that switches off, the decision about a second engagement is made from a position of strength. You are not deciding whether to keep the lights on; you are deciding whether a further, separately scoped piece of work would add something, with the first deliverable already in your hands regardless. That framing is the whole point of ending with a deliverable.
The first path, and for many founders the right one, is to run the deliverable yourself. This suits the founder who wanted a specific artefact built and the capability to use it, and who now has both. A 13-week cashflow you understand and update weekly, a model you can flex yourself, a board pack you produce each period, these are things a capable founder can run without ongoing help once they are built and handed over properly.
This path gets equal, respectful weight here because it is truly a correct outcome, not a failure or a lost sale. The engagement was designed to make you capable, and a founder who takes the deliverable and runs it independently has received exactly what the engagement promised. What running it yourself requires is modest: the discipline to maintain the artefact (update the forecast, refresh the model) and the understanding handed over in the final session. For a founder with that discipline, no further engagement is needed, and saying so plainly is part of the model.
The second path is a light ongoing cadence, and it exists for a specific reason rather than as a default. Some founders, having built the deliverable, want a regular rhythm around it: a fortnightly or monthly session to review the numbers, pressure-test decisions, and keep the analysis current as the business moves. This is real work with a real purpose, running the weekly cash meeting discipline with a second set of eyes, keeping a rolling forecast honest, bringing an outside perspective to the month’s decisions.
The honest framing is that a cadence is for founders who truly benefit from the rhythm and the outside input, not for founders who could run it themselves but are defaulted into paying anyway. If the ongoing sessions are doing real work, deciding things, catching things, they earn their cost. If they would just be a standing meeting to justify a retainer, they do not, and a good operator will tell you which it is. The cadence is a legitimate second engagement when it does real work, and it is scoped and priced separately, never rolled on automatically.
The third path sits between the first two: a quarterly review rather than a fortnightly or monthly cadence. This suits the founder who can run the deliverable themselves day to day but wants a periodic outside check, a quarterly session to review how the numbers have moved, refresh the model’s assumptions, and step back from the operational detail to look at the trajectory. It is a lighter, less frequent commitment than a cadence, and it fits founders who are largely self-sufficient but value an occasional expert pass over the numbers.
Quarterly reviews are often the natural middle path: more than nothing, less than an ongoing cadence, and well suited to a business that is running fine but benefits from a regular outside perspective at a sensible interval. Like the cadence, it is scoped and priced separately as its own engagement.
The way these paths get recommended matters as much as the paths themselves. A good operator recommends the path that fits the founder’s actual situation, including recommending that you need nothing further when that is the truth. The recommendation is not a soft sell toward a retainer; it is an honest read of whether further work would add value, made by someone who is willing to say “run it yourself, you do not need me for this.”
On pricing, the honesty is simple and structural: any ongoing work, a cadence, quarterly reviews, a further deliverable, is scoped and priced separately, as its own engagement. There is no default roll-on to a retainer, no automatic renewal, no arrangement where not-cancelling is how you end up paying. The 90-Day Number ends, and anything after it is a fresh, deliberate decision. That structure is what makes the run-it-yourself path a real option rather than a theoretical one, because leaving is the default, not the exception. For the ongoing-versus-project question in general, see the retainer discussion and choosing your 90-Day Number.
What do I have at the end of a 90-Day Number engagement?
The named deliverable you chose, the 13-week cashflow, financial model, unit economics build, or board pack, plus a working session that hands it over so you can run it yourself. It is yours: the model, the method, and the understanding of how it works. You end holding a finished, usable artefact, not a dependency that only functions while someone is retained.
Do I have to keep paying after day 90?
No. There is no default roll-on to a retainer and no automatic renewal. The engagement ends with you holding the deliverable, and anything after it, a cadence, quarterly reviews, a further deliverable, is a fresh, separately scoped and priced decision. Not-cancelling is never how you end up paying; leaving is the default.
Can I just run the deliverable myself?
Yes, and for many founders that is the right outcome. The engagement is designed to leave you capable: a 13-week cashflow you update weekly, a model you can flex, a board pack you produce each period. If you have the discipline to maintain the artefact and the understanding handed over in the final session, you need nothing further, and a good operator will tell you so.
What is an ongoing cadence for?
A fortnightly or monthly session for founders who truly benefit from a regular rhythm and outside input: reviewing the numbers, pressure-testing decisions, keeping the analysis current. It is a legitimate second engagement when it does real work, deciding and catching things, but not when it would just be a standing meeting to justify a retainer. A good operator distinguishes the two.
What is the difference between a cadence and quarterly reviews?
A cadence is a fortnightly or monthly rhythm for founders who benefit from frequent outside input; quarterly reviews are a lighter, less frequent check for founders who run the deliverable themselves day to day but want a periodic expert pass over the numbers. Quarterly reviews are often the natural middle path, more than nothing, less than an ongoing cadence.
How do you decide which path to recommend?
By reading the founder’s actual situation, including recommending nothing further when that is the truth. The recommendation is not a soft sell toward a retainer; it is a genuine read of whether more work would add value, from someone willing to say “run it yourself.” The run-it-yourself path is given equal weight because it is truly a correct outcome.
Is a second engagement more of the same?
Not necessarily. A second engagement is scoped to whatever would add value next, which might be an ongoing cadence, quarterly reviews, or an entirely different deliverable (a fundraise model after a cash forecast, say). It is scoped and priced separately based on what the business needs next, not a continuation of the first engagement by default.
