It is not alignment. It is a tax on your growth.
How Per-Resolution Pricing Works
The model is straightforward. Your AI support tool charges you a fee every time it successfully resolves a customer conversation without escalating to a human agent. The current rates across the industry:
- Intercom (Fin AI): $0.99 per resolution
- Zendesk (AI Agents): $1.00-$2.00 per resolution (varies by plan and commitment level)
- Help Scout (AI Answers): $0.75 per resolution
These fees are layered on top of your existing seat-based subscription. They are not replacing your monthly bill. They are adding to it.
The Math That Should Worry You
Let us walk through the numbers for a mid-stage SaaS company handling 2,000 customer conversations per month. Assume a reasonable AI resolution rate where most conversations are handled without a human.
Intercom:
- Base plan: 5 seats at $85/month (Advanced) = $425/month
- AI resolutions (1,500 of 2,000): 1,500 x $0.99 = $1,485/month
- Total: $1,910/month
Zendesk:
- Base plan: 5 agents at $115/month (Suite Professional) = $575/month
- Advanced AI add-on: 5 x $50 = $250/month
- AI resolutions (1,500): 1,500 x $1.50 = $2,250/month
- Total: $3,075/month
Help Scout:
- Base plan: $75/month (Plus, 100 contacts)
- Additional contacts: variable
- AI resolutions (1,500): 1,500 x $0.75 = $1,125/month
- Total: $1,200+/month
Now consider what happens when your business grows. Double your customer base, double your conversations. The seat costs stay flat or grow modestly. But the AI resolution fees double. Then triple. Then quadruple.
This is not hypothetical. Intercom users have reported costs jumping from $4,000/month to $9,000/month after enabling Fin AI. One user described a 120% AI cost increase in a single month without warning.
Why This Model Was Designed for Vendors, Not Customers
Per-resolution pricing creates a perverse incentive structure. The better your knowledge base, the clearer your product documentation, the more intuitive your onboarding — in other words, the better job you do as a company — the more conversations AI can resolve. And the more you pay.
You are being charged for building a good product.
The vendor benefits enormously from this model. Their marginal cost of serving an AI resolution is fractions of a cent. They are charging you $0.75 to $2.00 for compute that costs them almost nothing. The margin on per-resolution pricing is extraordinary — for them.
There is also the question of what counts as a "resolution." This is not a settled matter. Intercom's own community forum has active threads titled "Fin's flawed assumed resolved & pricing design." Users report being charged for resolutions where the AI provided incomplete or unhelpful answers. The customer left the chat frustrated, but the system logged it as resolved. You still paid $0.99.
The Budget Surprise Problem
The most practical damage from per-resolution pricing is unpredictability. SaaS operators plan budgets quarterly or annually. When your support costs are directly tied to conversation volume — which is tied to customer growth, product launches, seasonal spikes, outages, and feature releases — your support line item becomes impossible to forecast.
Teams that budget $500/month for AI have ended up paying $2,000 or more. The budget "surprise" is the single most common complaint about Intercom's pricing model. It is not an edge case. It is the model working as designed.
The Flat-Rate Alternative
There is a simpler way to price AI support. Charge a flat rate. Include AI. Include every conversation. Let the company grow without penalizing it.
At Corebee, support costs $99/month. That includes unlimited AI conversations, unlimited agents, and full AI action capabilities. There is no per-resolution fee. There is no per-seat surcharge. The price does not change when your customer base doubles.
The math is simple because it should be simple:
| 1,000 conversations/mo | 5,000 conversations/mo | 10,000 conversations/mo | |
|---|---|---|---|
| Intercom | ~$1,420 | ~$5,380 | ~$10,340 |
| Zendesk | ~$2,325 | ~$8,075 | ~$15,825 |
| Corebee | $99 | $99 | $99 |
Per-resolution pricing was not designed to reward you for building better support. It was designed to capture the value you create and redirect it to your vendor's revenue line. The more successful your support operation becomes, the more it costs.
That is not partnership. That is extraction.
The companies that understand this are switching to flat-rate models. Not because flat-rate is trendy, but because it is the only pricing structure where your success and your vendor's success are genuinely aligned. You grow. Your cost stays the same. Your margin improves.
Support pricing should be simple enough to fit on a napkin. If yours requires a spreadsheet, something is wrong. For a deeper look at how per-seat models compare to flat-rate across team sizes, see our per-seat vs flat-rate pricing analysis.
