Concentration is the first number we compute
An agency's riskiness is read fastest from one ratio: the largest client's share of fee income. Fee income, not gross billings; pass-through media inflates billings without adding a dollar of pricing power, which is why our agency accounting keeps the two apart. Lenders read this ratio, acquirers price on it, and it quietly sets how you behave in every negotiation with that account.
| Top client's share of fees | What it signals | The move |
|---|---|---|
| Well under a third | Losing them is a bad quarter, not a crisis | Normal pipeline discipline |
| Around a third | They set your pricing power | Longer notice terms, a deliberate pitch cadence |
| Half or more | You are effectively a dependent contractor | Run it as such: contract length, cost flexibility, no long fixed commitments |
This is the monthly cadence of Fractional CFO work: not a dashboard for its own sake, but a small set of numbers with a decision attached to each.
Utilization separates a team problem from a pricing problem
Two measures together diagnose almost any weak agency income statement. Utilization is billable hours over available hours for the delivery team. Effective rate is fees earned divided by hours actually delivered, per client. High utilization with weak profit means the pricing or the scope is broken and the team is fine. Healthy effective rates with weak utilization means a pipeline or capacity problem and the pricing is fine. Agencies that never split the two usually spend a year fixing the wrong one.
Flat retainers are where effective rate earns its keep: the fee is fixed while delivered hours creep, so an account degrades invisibly until renewal. A per-client effective-rate report turns each renewal into a priced decision instead of a relationship reflex.
Measure the denominator honestly. Count only delivery roles in available hours, keep founders' selling and admin time out of the billable pool, and treat internal projects as the investment they are rather than disguised utilization. An agency that flatters this number ends up hiring against capacity it never really lacked.
Retainer, project and value pricing allocate risk, not just revenue
Each model moves a different risk. Retainers smooth cash and hand scope risk to you. Projects price scope through change orders but leave cash lumpy and work sitting unbilled between milestones. Value or performance pricing pays best when outcomes land and makes revenue volatile when they do not. The CFO question is not which religion to join but the mix: enough contracted recurring fee income to cover fixed payroll and rent, project work carrying real change-order discipline, and performance kickers only where the client's own data can measure the outcome. That coverage ratio, fixed costs over contracted recurring fees, is one we watch every month, because it decides how frightening any single cancellation actually is.
Media float can sink a profitable agency
Platforms and publishers want their money on short terms, sometimes before a campaign runs; clients pay agency invoices on their own AP calendar, usually slower. Buy as principal and that gap is financed by you. The fixes, in the order we reach for them: media pre-funded by client deposit before spend is committed; the client paying platforms directly while you bill fees only; and where neither lands, an operating line sized to the float rather than to a round number. Lenders tend to misread agency balance sheets that carry gross media, and Walla Assaf's banking background plus Business Financing Advisory exist to put the case in lender language. The HST side of media billing is its own subject, handled with our agency tax services.
Hire the role or keep renting it
Freelancers flex with churn and cost more per delivered hour; employees cost less per hour only while steadily utilized, and they add fixed payroll plus real exit costs under Ontario employment law. Our rule: hire when contracted revenue, not the pipeline's hopes, keeps the role utilized through its notice period, and model the breakeven openly, freelancer premium against salary, payroll costs and bench risk. The middle exists too: contract-to-hire arrangements and fractional senior roles cover a growth spurt without betting a salary on a retainer that renews month to month. We run this math with agency founders across the GTA before the offer letter goes out, not after.
