Price a fractional CFO diagnostic as a fixed-fee, two-to-three-week engagement between $2,500 and $10,000, not as a discounted preview of your retainer rate. The diagnostic's job is to prove value fast enough to earn the retainer conversation, and pricing it too low undermines that proof before the engagement even starts.

How to Price and Sell a Fractional CFO Diagnostic
Price a fractional CFO diagnostic as a fixed-fee, two-to-three-week engagement between $2,500 and $10,000, not as a discounted preview of your retainer rate. The diagnostic's job is to prove value fast enough to earn the retainer conversation, and pricing it too low undermines that proof before the engagement even starts.
Why the diagnostic needs its own price, not a discount
A common mistake is pricing the diagnostic as a cheap taste of the real work, reasoning that a low price will make it an easy yes. This backfires because a client who pays very little tends to invest very little attention in return, and a diagnostic that looks free or nearly free doesn't carry the credibility of a paid engagement. The diagnostic, pilot, and retainer each have a different sales job to do, and each needs its own price to do that job:
| Tier | Typical price | Typical duration | What it proves to the prospect |
|---|---|---|---|
| Diagnostic | $2,500 to $10,000 | 2 to 3 weeks | Here's exactly where your business is leaking money, and what it's costing you |
| Pilot | $7,500 to $15,000 | 6 to 8 weeks | I can fix one of these problems, and here's the result to show for it |
| Partnership or retainer | $15,000 to $40,000-plus per month | Ongoing | Now that you've seen both, here's what it looks like to have this permanently |

Where to set your specific number inside the range
Set your diagnostic price based on two factors: the size of the business you're targeting, and how many diagnostics you need to run before you have enough proof to raise your rate. For businesses under roughly $2 million in revenue, the lower end of the range, $2,500 to $4,000, is more realistic. For businesses in the $5 million-plus range, $7,500 to $10,000 reflects the larger stakes and larger findings a diagnostic on that scale typically surfaces.
Do not price your first two or three diagnostics at your eventual target rate. Price them to get done, gather case studies, and raise the price once you have proof. This mirrors the same acquisition sequence covered in how fractional CFOs get their first 5 clients.
How to present the price without discounting it live
Present the diagnostic price as a fixed number stated before the prospect asks, not as something negotiated live on the call. State the price, the timeline, and the deliverable in the same sentence: "This is a $5,000, three-week engagement that ends with a prioritized report showing exactly where the opportunity sits in your business." Stating price and deliverable together, without a pause for negotiation, signals confidence that a hesitant, apologetic pricing conversation does not.
Handling the three most common objections
"That seems expensive for just an assessment."
Reframe the comparison: the diagnostic isn't priced against an hour of your time, it's priced against the cost of continuing to operate with an unexamined leak. If the diagnostic finds even one issue worth more than its own price, which is the explicit goal of the engagement, it pays for itself before the retainer conversation even starts.
"Can we just skip the diagnostic and go straight to a retainer?"
This is a good problem to have, but resist skipping the diagnostic. Michael Barbarita, owner of Next Step CFO, describes the risk of skipping straight to ongoing work without first demonstrating a specific, quantified finding: he had been "reviewing the same things over and over again" for existing clients before shifting to a more strategic, value-led posture that let him "add more value to my current clients... increase the fees I charge... expand my client base and predictably scale" (Michael Barbarita, ProGlobal Business Advisors testimonial). This testimonial reflects Michael's experience with ProGlobal Business Advisors' coaching methodology, not a Profit Wizard user outcome. The diagnostic is what creates that specific, quantified starting point; skipping it removes the evidence that justifies the retainer price later.
"I need to think about it."
This objection is frequently really a request for lower risk, not lower price. Offer a smaller, bounded diagnostic scope (one function, such as pricing or cash flow, instead of the full four-area review) at a lower price point rather than discounting the full diagnostic. A bounded, lower-risk offer converts hesitation more reliably than a blanket price cut on the original offer.
Running the diagnostic itself: what actually goes into it
A fractional CFO diagnostic typically reviews financial and operational questions across the same categories an experienced CFO already covers in a discovery call, compressed into a fixed, time-boxed engagement rather than an open-ended one. To see how a structured, dollar-quantified diagnostic works in practice before you build your own from scratch, start the Profit Wizard on your own numbers. It estimates profit opportunity across four quadrants in about three minutes, giving you a firsthand look at what a fast, structured diagnostic experience feels like from the client's side of the table.
What to include in the diagnostic deliverable
Regardless of price, every diagnostic should end with three concrete elements: a prioritized list of findings ranked by dollar impact, a specific number attached to at least the top finding, and a clear next step, whether that's a pilot engagement or a retainer proposal. A diagnostic that ends in a vague summary without a ranked, dollar-quantified finding does not do the sales job it's priced to do.

Frequently asked questions
Should I ever offer the diagnostic for free to win a client?
Generally no. A free diagnostic removes the credibility signal that a paid, fixed-price engagement provides, and it also removes the natural on-ramp to the pilot and retainer tiers, which are priced against the diagnostic's proven value.
What if a prospect wants a custom scope instead of my standard diagnostic?
A narrower, bounded scope at a lower price is a reasonable accommodation. An open-ended scope at your standard price is not, since it breaks the fixed-fee, fixed-timeline structure that makes the diagnostic sellable in the first place.
How do I know if my diagnostic price is too low?
If prospects accept the price instantly with no hesitation at all, it is worth testing a higher number on your next few prospects. Some friction on price is a normal, healthy part of a real sales conversation.
