If someone walked up to you with blood pouring from their arm, you wouldn't hand them a gym membership. You'd stop the bleeding. That instinct — stop the bleeding before suggesting a new workout — is exactly why Cost of Inaction beats Return on Investment as a prioritization tool for buyers and a selling strategy for reps.
People will always prioritize fixing a problem over chasing potential improvements. Sales leaders already know this, which is why SPICED, MEDDPICC, and even BANT focus on need and pain. But the backbone of most business cases — the classic Return on Investment calculation — completely misses the pain conversation and makes every deal more like a gym membership and less like a life saver.
Cost of Inaction is a better tool to evaluate problems and make buying decisions. Let's look at why, and then outline how to make the swap with minimal disruption.
Technical Primer
ROI — Return on Investment
ROI is a positive number that shows an increase in money after some lesser amount of money is spent. Return is the increase; Investment is the spend.
ROI is typically expressed as a ratio, though a dollar figure works too by looking at the Return on its own (gross) or Return minus Cost (net).
COI — Cost of Inaction
COI is a negative dollar value. It contrasts the buyer's status quo against an ideal golden or achievable state. COI assumes the existence of a problem — a drain, a draw, a leak constantly dripping money out of an organization — that will continue to cost money until some action is taken to stop the bleeding.
Achievable value minus current value = cost of inaction.
COI has no comment on the cost required to fix a problem, how to fix the problem, or even if the problem is fixable; it simply quantifies the extent and financial impact of the pain.
While both ROI and COI can apply to a one-off event or change over time, ROI is usually shared as a standalone figure, whereas Cost of Inaction nearly always has a time axis like "X dollars per quarter".
Even though the Return on a proposed change could be the exact same absolute dollar value as the cost of inaction, these two structural differences (again vs. loss & one-off vs. over time) fundamentally change the buyer-seller conversation.
Why COI Is Better than ROI
COI has three major advantages over traditional ROI:
- It forces a two-part discussion, splitting out the problem from the solution.
- It taps into base human psychological impulses around loss aversion.
- It forces a "why now" urgency consideration.
1. Splitting Out Problem vs. Solution
Value Selling, SPICED, MEDDPICC, and BANT all center around understanding and solving for a customer problem. But in their 2024 State Of Business Buying report, Forrester Research found that 82% of B2B decision-makers consider sales reps fundamentally unprepared for discovery, often jumping to demos and pitch decks far too quickly. The result: 87% of buyers say the seller didn't actually understand their business. That leads to lost deals.
By starting the buyer journey with COI, the rep and the buyer are forced to quantify — or at least approximate — the pain the customer is experiencing. The buyer and the seller collaborate to confirm that there really is a problem worth fixing, and that it's significant enough to spend time finding a solution.
Pipeline inspection gets a new signal too: no COI = unhealthy deal.
2. Buyer Psychology
Human nature makes us hate loss more than we value gain. There are decades of experiments proving this, known collectively as the "endowment effect." A classic example from Kahneman, Knetsch, and Thaler: researchers asked subjects how much they'd pay for a coffee mug. They said a couple of dollars. But when researchers gave subjects the same mug and then asked what they'd sell it for, the selling price averaged 2x the buying price — simply because it was theirs now. Loss aversion is real.
COI applies that to your buyer: losing money that's "rightfully" yours feels worse than gaining "new" money.
This does three things for the seller. First, it adds an emotional component to the buyer-seller conversation. Second, it flips the script so the status quo takes on the burden of risk rather than that burden falling on your proposed change. Third, the psychological switch makes early-stage conversations easier because the seller isn't talking about their product — they're talking about a problem the buyer is experiencing.
3. Forcing a "Why Now" Conversation
COI should always be presented as a cost per unit of time. The longer you fail to act, the higher the cost. The drip, drip, drip of leaking money creates pressure against inaction and no-decision.
For sellers who need a compelling event, COI acts as a backstop — especially useful in industries without true external forcing functions like pending legislation or regulatory deadlines.
Finally, COI lets you talk about numbers way earlier in the conversation. You and the buyer get a sense of proportion. Are you in the same ballpark on the figures? Are these numbers significant enough to act on?
Make the Switch
-
Find your ROI intro moment. Review your buyer journey and mark where sellers first introduce an ROI concept. It's probably after you've discussed pricing. That's too late.
-
Add COI into early discovery. Scrap the ROI moment and introduce the cost-of-inaction discussion in early to early-mid discovery instead. This gets your sellers talking about numbers early and establishes that there is a problem to solve — critical to generate urgency in your buyer and qualify the deal for your sales process.
-
Establish default numbers for your COI calculator. No one likes a blank page. Come up with sensible "status quo" starter values for the KPIs you're impacting. Make sure your seller is always clear that this is a first hypothesis / best guess. Something is better than nothing and shows you know at least something about their industry. It's also easier for a buyer to react against something and correct it. Again, the goal is to validate with the champion before getting into any solutioning.
If the KPI you address is not a percentage (like "support tickets per year" vs. "win rate") then it's helpful to your seller if you have a simple math method to get to absolute numbers from a publicly accessible input value (like ARR or headcount). Otherwise your seller will have to manually adjust the defaults based on the size of the company, which is a hassle for your seller and prone to error.
-
Establish your "achievable / golden state" of that same KPI. Ideally you're using a Canary Metric (more on this below) to bring the customer's own numbers into your calculator. Otherwise, back your estimates with third-party benchmarks. Note that without hard evidence (or a buyer's own canary metric, see below) this delta is a magic multiplier, so be prepared to defend it.
-
Position the cost of your change against this cost of inaction. Always position as cost over time, with a 2 or 3 year cumulative window to show an increasingly expensive future if the buyer chooses to do nothing.
A FOMU Hail Mary
COI forces a conversation about the problem before moving to the solution, and lets the seller talk as an expert before pitching the virtues of their product. That's just part of being a good problem-solving seller.
But COI also gives you a fantastic parting shot of FOMU (Fear Of Messing Up) for prospects who choose not to engage:
"I totally hear that you don't think this is an issue for you. 'Do Nothing' is the most common course of action for any problem in the world. But before you go — why don't we at least quantify the cost of not acting, so if later on someone asks why you didn't do anything, you have some numbers to back up your decision."
COI: Necessary but Insufficient
A parting note: You could have the best COI numbers in the world, but if the buyer doesn't believe the numbers, or worries about hidden costs within change management, there's no deal.
In upcoming posts, we'll cover the two other critical complements:
Canary Metrics — Buyers are skeptical of vendor numbers. A Canary Metric is a leading indicator of the root cause of the customer's problem, measurable in the customer's own systems. Instead of "trust me," you're saying "these are your numbers from your own org." Canary Metrics make your COI credible.
Change Plans — Budget is rarely the real reason someone won't buy. The real blockers are disbelief in your value prop or fear that implementation and adoption will fail. A Change Plan shows your team has a tested path to success — and guards against the "we'll just build it with AI" objection.
More on both soon. Meanwhile, make the move from ROI to COI and just watch the quality of your sellers' discovery and champion-enablement soar.
