Fractional CFO support for Toronto agencies and consultancies
Reviewed by EverStone CPA · July 2026
An agency sells time it cannot store, on terms it rarely sets, to clients who can leave at ninety days’ notice. Almost every financial weakness in the model traces back to one of those three facts. This page covers part-time CFO work on them; the general offering is on the fractional CFO page.
Quick answer: A fractional CFO is part-time senior financial leadership. For a Toronto agency the work centres on the mix between retainer and project revenue, whether the pricing model matches how value is delivered, client concentration, and the cash absorbed by pass-through spend.
Revenue mix decides how stable the business is
Retainer revenue and project revenue behave completely differently. A retainer base covers fixed cost predictably and makes staffing plannable. Project revenue is lumpier, often higher margin, and disappears without warning. The ratio between them is the single largest determinant of how much risk the business carries, and most agencies have never set it deliberately.
The useful exercise is establishing what proportion of fixed cost the retainer base currently covers, and what proportion it would need to cover for the business to survive losing its largest project client without cutting staff. That number becomes a target rather than an observation, and it changes which new business is worth pursuing.
Does the pricing model match the work?
Hourly billing rewards inefficiency and caps the upside on work that is genuinely valuable. Fixed-fee project pricing transfers estimating risk to the agency, which is fine when estimates are reliable and punishing when they are not. Retainers smooth revenue and quietly invite scope creep. Value-based pricing works where the outcome is measurable and fails where it is not.
None of these is correct in general and each is correct for particular work. The problem in most agencies is that one model was adopted early and applied to everything since, including engagements it fits badly. Reviewing what is priced how, against how each type of work actually consumes resources, tends to find both a set of engagements that are underpriced and a set where the model itself is wrong.
Client concentration and the ninety-day problem
Agency contracts typically allow a client to leave at short notice. That makes concentration a live risk rather than a theoretical one: an account representing a large share of revenue can be gone within a quarter, taking with it the margin that funds the overhead the agency has built around it.
Quantifying it is straightforward and rarely done. What proportion of revenue and of contribution comes from the top account, the top three, the top five? What would need to be cut, and how quickly, if the largest one left? Knowing that does not prevent a loss, but it does inform how much fixed cost the agency should carry and how hard it should be working on new business while everything looks fine.
Pass-through spend and the cash it consumes
Where an agency commits to media, print or production on a client’s behalf, it is frequently paying the supplier before the client pays it. The amounts can dwarf the agency’s own fee, which means a large campaign can consume more working capital than the agency earns from the entire relationship.
The financial responses are limited and worth choosing deliberately: bill the pass-through in advance, arrange for the client to contract directly with the supplier, negotiate supplier terms that match the client’s payment cycle, or size a facility to cover the exposure. Doing none of these and absorbing it is a decision too, and it is the one most agencies make without noticing. The year-end statements page covers how the same spend is presented.
Capacity, hiring and the cost of standing still
An agency’s capacity is its people, and both over- and under-staffing are expensive. Carrying capacity for work that has not been won burns cash directly. Running permanently short means declining work, leaning on freelancers at lower margin, and eventually losing accounts to delivery problems.
Managing the tension needs a forward view of committed work against available capacity, refreshed monthly, so hiring decisions are made against a pipeline rather than against the last busy fortnight. It also needs an honest figure for what an additional person must bill to cover their fully loaded cost, which is generally higher than the rate card implies once non-billable time is counted.
When an agency does not need this
If time is not being recorded against clients and projects, none of the above can be calculated, and that is the first thing to fix. Similarly, an agency of a handful of people where the founder is across every account and every invoice is unlikely to learn much from formal financial oversight.
The point at which it starts to pay is usually a specific discomfort: growth that has not improved profit, a client loss that hurt more than expected, a pricing model that no longer fits, or partners who disagree about what the numbers mean. Absent one of those, better time recording and a timely year end deliver more. See agency and consulting accounting.
How the engagement works
EverStone is a sole practitioner CPA firm with one office, in Abbotsford, British Columbia, and no Toronto office. Engagements are delivered remotely through video calls, secure document exchange and electronic signature. The time difference means work sent at the end of a Toronto day is generally addressed before the next one starts.
This suits incorporated marketing and creative agencies, digital and media shops, management and technology consultancies and independent professional firms. Related page: Toronto agency accounting.
