Dear Calcy: My CEO Wants to Vibe Code Our Comp System

Dear Calcy,

Our CEO just walked out of a leadership offsite fired up about AI, then pulled me aside. "Why are we evaluating commission software when we could just vibe code something ourselves?” she said. “It's 2026. How hard could it be?"

Part of me wanted to agree. But I also know our comp environment: 15 plans, SPIFFs, clawbacks, mid-year amendments, and a sales team that disputes payouts like it's a competitive sport. I'm not anti-AI. I just don't want to agree to something that turns into a fiasco six months from now. How do I make my case without sounding like I'm defending the status quo?

Signed,

Dear Cautiously Optimistic in Comp,

Ah, vibe coding. How hard could it be, right?

Here's the truth your CEO needs to hear: 

AI has absolutely changed what's buildable. You can build a working commission calculator that has rates applied to deals, is connected to Salesforce, and looks demo-ready, in a single afternoon now. Acknowledge it. Don't fight it. That part is real.

What your CEO is underestimating is what "built" means for a system that touches every paycheck on your sales floor. A commission calculator applies math. But a commission system earns trust — every cycle, from every rep, with full accountability to Finance, Legal, and anyone who ever asks "show me how you got that number." Those are not the same thing. 

The gap between the demo and production is where homegrown comp tools go to die. That’s why even the companies with the strongest AI engineering talent in the market buy purpose-built comp platforms rather than build. They know the difference between a prototype and a platform.

Here's how to walk your CEO through it:

1. Define "done" before you agree to anything

Ask your CEO what success actually looks like — not the launch, the steady state. Remind her that while the prototype takes a weekend, the production version takes 18 months and a dedicated engineer. Who updates the logic when the comp plan changes in Q3? (And it will change in Q3.) Who maps the new Salesforce field? Who handles the rep who gets an edge case the calculator has never seen before? "We'll figure it out" is not a maintenance plan. Get the answers before you're living the questions.

2. Make the true cost undeniable

The build is never the real cost. It's everything that comes after. Every GTM change, every new integration, every mid-year exception — someone has to reopen the code, retest it, and redeploy it. According to CaptivateIQ's 2026 State of ICM Report, 77% of salespeople have experienced payout errors and 66% of companies have overpaid or underpaid commissions — and most of those teams aren't running on weekend prototypes. Production-grade comp is hard even with purpose-built tools. The same report found that 34% of compensation leaders say fixing calculation errors from manual processes is a top ongoing challenge. A homegrown build doesn't make that easier. It just makes it your engineering team's problem too.

3. Ask what happens when the builder leaves

Commission logic has a way of living in one person's head. The scripts are half-documented. The edge cases are handled with tribal knowledge and a prayer. When that person leaves, whoever inherits the tool starts from zero. The industry calls this “technical amnesia” and it’s the most common reason companies abandon homegrown comp tools within two years. Put it on the table now, before anyone's committed.

4. Bring Finance and Legal into the room 

A vibe-coded tool can demo beautifully and still fail its first audit. SOC 2 Type II compliance, encryption, role-based access controls, and full audit trails on every payout — that's a separate engineering project from the calculator. Every commission payment your company makes will eventually need to be traceable back to source data: for disputes, for audits, for M&A due diligence. "We built it ourselves" is a fine answer for a Slack bot, but it’s a terrifying answer for payroll infrastructure.

5. Don't say no to AI. Come in with a better AI vision.

This is where you get to be the strategic one.

Don't walk into that room as the person who killed the AI idea. Walk in as the person who understands it well enough to know where it actually belongs, which is a much more powerful position.

AI in comp, done right, is exciting. Building commission plans by describing them in plain language and letting AI translate intent into logic — real. Automatically handling day-to-day inquiry resolution so reps get answers without filing tickets — real. Running what-if scenarios across quotas, territories, and payouts before anyone commits to a plan change — real. Those capabilities exist inside purpose-built platforms that have spent years building the infrastructure AI needs to be trustworthy at payroll scale.

The goal isn't "we vibe coded it ourselves." The goal is "we use AI-powered comp tools that do things spreadsheets and legacy systems never could." Bring her that vision, and you won't sound like someone defending the status quo. You'll sound like the person with an AI strategy worth listening to. 

Good luck!
Calcy 💸
