Short answer: there are five billing models in this market — per seat, per ticket, per conversation, per resolution, and flat — and most vendors now run two of them at once. The headline price you see is almost always the seat meter; the AI you are actually buying sits on a second meter underneath it. At 500 tickets a month the gap between the cheapest and the most expensive option on this page is about 6×. At 20,000 tickets a month it is about 165×, and the ranking changes completely.
The three words that are not synonyms
This is the part every pricing comparison skips, and it is the part that decides whether a quote is cheap.
A ticket is a case record in the help desk. One customer with one problem, opened and closed. If the same person writes back three weeks later about something else, that is a second ticket.
A conversation is a thread. It may contain several tickets, or none — a visitor who asks one question in the widget and leaves has had a conversation and generated no ticket. Vendors that bill per conversation usually further split it into "billable conversations" (a human was involved, or a threshold of messages was crossed) and everything else. Tidio, for example, meters billable conversations and Lyro AI conversations as two separate counters that both bill.
A resolution or an outcome is counted only when the AI actually closes something. Intercom's Fin defines an outcome as a customer confirming their issue was answered — you are not charged when Fin tries and fails. Zendesk calls the same idea an Automated Resolution. Help Scout's AI Answers bills per resolution at $0.75.
Why this matters: the same month of support can produce very different counts under each unit. A team taking 1,000 tickets might see 1,400 conversations and 600 AI resolutions. So $0.99 per resolution is not automatically worse than $0.40 per ticket — it depends entirely on how many of each you generate. Before you compare two prices, make the vendors tell you which event triggers the meter and where the counter resets.
Two more questions worth asking in the same breath:
- What counts as a failed attempt? If the AI answers and the customer still escalates, does that bill?
- What happens to the AI meter when the AI gets better? Under per-resolution pricing, a model improvement is a bigger invoice. This is the structural point of the whole article.
The five models
1. Per seat (or per agent, or per user)
You pay for each person with a login, every month, whether they work a ticket or not. It is the oldest model and the easiest to forecast — until you hire.
Published 2026 examples: Zendesk Suite Professional $115 per agent/month paid yearly; Freshdesk Pro $55 per agent/month billed annually; Help Scout Plus $45 per user/month; Front Professional $65 per seat/month billed annually; Chatwoot Business $39 per agent/month billed annually; Intercom Advanced $85 per seat/month; HubSpot Service Hub Professional from $90 per seat/month; Richpanel Pro $99 per user per month.
Where it bites: part-time responders. The person in ops who answers four tickets a month costs the same as your best agent. Some vendors mitigate this with "light users" or day passes — Freshdesk sells day passes at $2, $7 and $12 depending on tier — which is worth asking about explicitly.
2. Per ticket
You pay per case, usually as overage above an included allowance rather than from the first ticket.
Published 2026 examples: Gorgias includes 50 / 300 / 2,000 / 5,000 tickets per month by plan and, in its own words, charges a $0.40 per-ticket fee past your limit on the lower tiers and $0.36 on the higher ones. eesel.ai is the purest form of the model — $0.40 per support ticket or chat session, with no subscription at all on its standard plan.
Where it bites: seasonality. A Black Friday spike bills at exactly the moment your margin is thinnest.
3. Per conversation
You pay per thread. Cheaper per unit than per resolution because it fires more often.
Published 2026 examples: Front's AI agent from $0.05 per conversation — the lowest published usage rate we found anywhere. Tidio bills billable conversations and Lyro AI conversations on separate meters. Crisp bundles AI credits into each plan and quantifies them in conversations: roughly 90, 450 and 1,350 automated conversations on its $45, $95 and $295 tiers.
Where it bites: definitional drift. "Conversation" is the least standardised unit in this market. Get the definition in writing.
4. Per resolution / per outcome
You pay when the AI closes something. The fairest-sounding model and the one that punishes success hardest.
Published 2026 examples: Intercom Fin $0.99 per outcome; Help Scout AI Answers $0.75 per resolution; Re:amaze $0.85 per additional resolution past the 5–20 per user per month included by tier; Gorgias AI Agent $1.00 down to $0.85 per automated interaction by plan, with a $1.50 per-interaction fee past the plan limit; HubSpot's Customer Agent burns 50 credits per resolved conversation against credits priced at $9 per 1,000 annually, which works out to about $0.45 per resolved conversation. Zendesk states that its AI agents are billed per Automated Resolution but does not publish the per-unit rate on its pricing page — if you are evaluating Zendesk, that number has to come from a salesperson.
Where it bites: the incentive inversion. Every improvement in the AI, every article you add to the knowledge base, every bit of work you do to make deflection better raises the bill. You are paying a success tax on your own operational effort.
5. Flat
One price for the account, regardless of seats or volume.
Published 2026 examples: Corebee $99/month for the account, with unlimited AI conversations and unlimited team members and no second meter. Crisp $0 / $45 / $95 / $295 per month per workspace, with 4 / 10 / 20+ seats included and a bundled AI credit allowance that can be exhausted. Re:amaze Starter $59/month flat with unlimited team members, capped at 500 responded conversations per month. Drag is also flat at roughly $18 per month — worth naming, because "flat" is not a category any one vendor owns.
Where it bites: you pay the same in a quiet month. Flat pricing is a hedge, and like any hedge it costs something when the risk does not materialise. See scenario A below, where a flat plan is not the cheapest option.
Worked example A — 500 tickets a month
Every input, stated: 500 customer conversations per month · 3 agents with logins · 60% of conversations routed to and resolved by AI = 300 AI resolutions/month · annual billing where the vendor publishes an annual rate · US pricing · no add-ons beyond the AI meter · one-time onboarding fees excluded from the monthly figure and flagged separately.
| Vendor & plan | Seat cost | AI cost | Modelled monthly total |
|---|---|---|---|
| Crisp Essentials (10 seats incl.) | $95 flat | ~450 automated conversations included | $95 |
| Corebee | $99 flat, unlimited seats | none | $99 |
| eesel.ai | none | 300 × $0.40 | $120 (plus whatever help desk you already run) |
| Chatwoot Business | 3 × $39 = $117 | Captain AI credits, $20/1,000 — no published conversion | $117 + credits |
| Front Professional | 3 × $65 = $195 | 300 × $0.05 = $15 | $210 |
| Freshdesk Pro + Copilot | 3 × $55 + 3 × $29 = $252 | first 500 AI Agent sessions included | $252 |
| Zendesk Suite Professional | 3 × $115 = $345 | per automated resolution, rate not published | $345 + AI |
| Help Scout Plus | 3 × $45 = $135 | 300 × $0.75 = $225 | $360 |
| Re:amaze Plus (annual) | 3 × $62.10 = $186.30 | 60 incl., 240 × $0.85 = $204 | $390 |
| Gorgias Basic (annual) | $77 + 200 tickets × $0.40 = $157 | 30 incl., 270 × $0.90 = $243 | ~$400 |
| HubSpot Service Hub Professional | 3 × $90 = $270 | ~300 × $0.45 = $135 | $405 (+ $1,500 one-time onboarding in year one) |
| Intercom Advanced | 3 × $85 = $255 | 300 × $0.99 = $297 | $552 |
Read this honestly: at this volume Corebee is not the cheapest option on the page. Crisp Essentials comes in $4 lower and includes ten seats. eesel.ai is cheaper still if you already have a help desk and only want the AI layer. Spread between cheapest and most expensive: about 5.8×.
Worked example B — 5,000 tickets a month
Every input, stated: 5,000 conversations/month · 8 agents · 60% AI-resolved = 3,000 AI resolutions/month · annual billing where published · one-time fees excluded and flagged.
| Vendor & plan | Seat cost | AI cost | Modelled monthly total |
|---|---|---|---|
| Corebee | $99 flat, unlimited seats | none | $99 |
| Crisp Unlimited | $295 flat, 20+ seats | ~1,350 automated conversations included; the remaining ~1,650 need additional credits, and Crisp publishes no per-conversation rate | $295 + unquantified AI credits |
| Chatwoot Business | 8 × $39 = $312 | credits, no published conversion | $312 + credits |
| Front Professional | 8 × $65 = $520 | 3,000 × $0.05 = $150 | $670 |
| Zendesk Suite Professional | 8 × $115 = $920 | rate not published | $920 + AI |
| eesel.ai | none | 3,000 × $0.40 | $1,200 (plus your help desk) |
| Freshdesk Pro + Copilot | 8 × $55 + 8 × $29 = $672 | 500 incl., 2,500 more = 25 × $49 = $1,225 | $1,897 |
| HubSpot Service Hub Professional | 8 × $90 = $720 | ~2,940 × $0.45 = $1,323 | $2,043 (+ $1,500 onboarding yr 1) |
| Help Scout Plus | 8 × $45 = $360 | 3,000 × $0.75 = $2,250 | $2,610 |
| Re:amaze Plus (annual) | 8 × $62.10 = $496.80 | 160 incl., 2,840 × $0.85 = $2,414 | $2,911 |
| Gorgias Advanced (annual) | $1,227 (5,000 tickets incl.) | 530 incl., 2,470 × $0.85 = $2,100 | ~$3,327 |
| Intercom Advanced | 8 × $85 = $680 | 3,000 × $0.99 = $2,970 | $3,650 |
Spread: about 37×. The ordering has already changed from scenario A — Crisp has moved above Corebee because its bundled AI credits ran out, and Gorgias has moved from the middle of the table to near the top.
Worked example C — 20,000 tickets a month
Every input, stated: 20,000 conversations/month · 20 agents · 60% AI-resolved = 12,000 AI resolutions/month · annual billing where published. At this volume several vendors move you to a custom quote, which is noted in the row.
| Vendor & plan | Seat cost | AI cost | Modelled monthly total |
|---|---|---|---|
| Corebee | $99 flat, unlimited seats | none | $99 |
| Crisp Unlimited | $295 flat | ~1,350 incl. of 12,000; rest on credits, no published rate | $295 + substantial AI credits |
| Chatwoot Business | 20 × $39 = $780 | credits, no published conversion | $780 + credits |
| Front Professional | 20 × $65 = $1,300 | 12,000 × $0.05 = $600 | $1,900 |
| Zendesk Suite Professional | 20 × $115 = $2,300 | rate not published | $2,300 + AI |
| eesel.ai | none | 12,000 × $0.40 | $4,800 (plus your help desk) |
| HubSpot Service Hub Professional | 20 × $90 = $1,800 | ~11,940 × $0.45 = $5,373 | $7,173 |
| Freshdesk Pro + Copilot | 20 × $55 + 20 × $29 = $1,680 | 500 incl., 11,500 more = 115 × $49 = $5,635 | $7,315 |
| Help Scout Plus | 20 × $45 = $900 | 12,000 × $0.75 = $9,000 | $9,900 |
| Re:amaze Plus (annual) | 20 × $62.10 = $1,242 | 400 incl., 11,600 × $0.85 = $9,860 | $11,102 |
| Intercom Advanced | 20 × $85 = $1,700 | 12,000 × $0.99 = $11,880 | $13,580 |
| Gorgias — above published plans | $1,227 + 15,000 tickets × $0.36 = $6,627 | 530 incl., 11,470 × $0.85 = $9,750 | ~$16,377, extrapolated — Gorgias publishes no plan at this volume and would quote |
Spread: about 165×, and the ordering has inverted. The vendors that looked cheapest at 500 tickets are the most expensive at 20,000, because their seat price was the small number and their AI meter was the large one.
The one line to take away: in every scenario above, the seat price moved by about 6× while the AI meter moved by 40×. When you evaluate a support tool in 2026, you are mostly choosing an AI meter.
Modelling caveats — read before you quote these numbers
- These are modelled figures from published list prices, not invoices. Annual commitments, volume discounts, negotiated rates and promotional pricing all change them, usually downward.
- The 60% AI resolution assumption is ours, applied uniformly so the vendors are comparable. It is not a claim about any product's actual performance, including Corebee's. Your rate depends on your documentation, your query mix and your configuration. Substitute your own number and the tables re-rank.
- One-time fees are excluded from the monthly totals. HubSpot Service Hub Professional requires a $1,500 one-time onboarding fee and Enterprise $3,500. In year one at 500 tickets, that fee alone is larger than eleven months of several plans on this page.
- Where a vendor does not publish a rate, we have said so rather than estimated. Zendesk's per-automated-resolution price and Chatwoot's credits-per-conversation conversion are both absent from their pricing pages. Crisp publishes AI credits as dollar bundles, not as a per-conversation rate, so its overage cells are unquantified by design.
- Gorgias has five moving variables — base fee, ticket allowance, ticket overage, automated-interaction allowance, automated-interaction overage — and its page shows both a per-plan automated-interaction rate ($1.00–$0.85) and a $1.50 fee past the plan limit. We modelled the plan rate. Confirm which applies to you.
- eesel.ai is a layer, not a help desk. Its totals are additive to whatever you already run.
- Prices change without notice. Every figure here is linked to its source; check before you buy.
What flat pricing actually claims — and what it does not
Corebee's price is $99 per month for the account: unlimited AI conversations, unlimited team members, all features, 14-day free trial, 30-day money-back guarantee, no annual contract. (pricing)
Here is the claim, stated precisely, because the loose version is wrong:
Corebee is not the only flat-rate vendor in this market. Crisp bills per workspace and markets unlimited conversations. Re:amaze has a $59 flat tier. Drag is around $18 flat. Anyone telling you flat pricing is unique to one product is selling.
What is defensible is narrower and more useful: Corebee's price does not change when the team grows, when volume grows, or when the AI resolves more. There is no second meter to exhaust. Crisp's AI credits run out. Re:amaze's flat tier caps at 500 responded conversations. Corebee's does not have that ceiling, and that is the specific difference — not the existence of a flat number.
And be clear about the other side of it: at scenario A, Crisp is cheaper. A flat price is a hedge against volume risk. If you do not have volume risk, you are paying for insurance you do not need.
Watch the unit on identical headline numbers. Corebee publishes $99. Richpanel also publishes $99 — per user per month on its Pro help-desk tier ($85/user billed annually), alongside a separate order-volume self-service product at $0 / $120 / $360 per month. Five agents makes those two "$99" prices $99 and $495. This is the most common misread in the category, and AI-generated comparisons make it constantly.
