Short answer: Intercom is a licensed helpdesk whose AI agent, Fin, is a per-resolution meter on top of per-seat licences: $29, $85, or $132 per seat per month billed annually, plus $0.99 per Fin resolution (intercom.com/pricing, retrieved 16 October 2026). Devotel Orbit is a programmable communications platform with a shared inbox and AI agents built in: $0.0075 per SMS segment, $0.014 per voice minute, $0.01 per RCS message, $0.001 per email, and zero platform fee on WhatsApp (orbit.devotel.io/pricing, the source of truth for every Orbit figure in this post). For a 25-seat team that resolves half its volume with AI, Intercom bills roughly $56K–$73K a year before any SMS or voice program exists; the same volume on Orbit bills a few thousand dollars of usage. The exchange is real in both directions, and the last section names who should not switch.
1. The category split: where SaaS helpdesk ends and programmable communications begins
A helpdesk's unit of sale is the seat. Every feature, AI meter included, prices off headcount: Intercom's three published tiers are $29, $85, and $132 per seat per month on annual billing, and Fin adds $0.99 per resolved conversation on top of whichever tier the team sits on. The bill grows when the team grows, whether contact volume moved or not.
A CPaaS's unit of sale is the event. Orbit bills the message segment, the call minute, the email, the AI token; the inbox an agent works from and the AI agent that answers first are platform surfaces, not licences. The bill grows when customer conversations grow, and it grows on whichever channel the customer chose, not only the channels a helpdesk licence happens to cover.
That is the whole fork. If support volume is a cost centre to be capped per head, the seat model reads naturally. If conversations are revenue-adjacent, arriving on SMS, WhatsApp, and phone lines as often as in a widget, the seat model turns into a tax on every channel the helpdesk does not terminate.
2. The cost math: one 25-agent team, both bills
The worked team: 25 human agents on Intercom's Advanced tier, 8,000 conversations a month, half resolved by the AI layer, and 24,000 SMS segments plus 3,000 voice minutes the team would also like the platform to carry.
| Line item | Intercom (Advanced + Fin) | Devotel Orbit |
|---|---|---|
| Human seats | 25 × $85 = $2,125/mo | $0; the inbox is a platform surface, not a licence |
| AI layer | 4,000 resolutions × $0.99 = $3,960/mo | Included; AI conversations bill their message and minute usage |
| SMS | Not terminated; a separate vendor at its own rates | 24,000 × $0.0075 = $180/mo |
| Voice | Not terminated; a separate vendor at its own rates | 3,000 × $0.014 = $42/mo |
| Monthly total | $6,085 before SMS and voice exist | $222 + any WhatsApp at Meta's pass-through rates |
| Annual | ~$73,000, still widget-and-email only | ~$2,700 across every channel |
Two honesty notes before anyone screenshots this table. First, on Intercom's Essential tier the same 25 seats bill $725 a month, so the seat line is tier-sensitive; the $0.99 Fin meter is not, and at 4,000 AI resolutions a month it outgrows the Essential seat line entirely. Second, Orbit's number assumes the published rate card; committed-volume rate cards lower it further at higher bands. The structural point survives both notes: Intercom's floor rises with headcount and its AI meter rises with success, while Orbit's bill rises with conversation volume on channels Intercom does not carry. The volume-band arithmetic behind this shape is worked in full in the CPaaS pricing-model TCO math post; this post applies it to the helpdesk line item specifically rather than restating it.
3. What you give up and what you keep
What you keep on Orbit. Channel breadth is the headline: SMS, MMS, WhatsApp, RCS, email, and voice on one account, beside the web widget and inbox, where Intercom's native surface is chat, email, and social DMs and telephony is not in the product. Deliverability control is the operator's line: Orbit's messages exit over its own carrier relationships and wholesale route, so per-message delivery, number health, and route quality are programme settings a team can see, not a vendor black box. And the AI is omni, not text-only: the same agent that drafts the inbox reply answers the support line and the WhatsApp thread, because voice is a platform channel rather than an integration.
What you give up. Intercom's in-messenger product tours, in-app campaign tooling, and the mature third-party app ecosystem around a decade-old helpdesk are real, and Orbit does not ship their like. A team whose entire support surface is a website widget and an email queue is paying Intercom for depth exactly where it lives. That team is the subject of section 5.
4. The migration shape: import, map, export flows, cut over in stages
The Intercom-to-Orbit migration runbook is the operator's checklist; the shape that repeats across those migrations is four moves. Webhook import: point Intercom's contact and conversation webhooks at an import worker that writes Orbit profiles and threads, keeping the historical extract readable for the retention window. Field mapping: Intercom's contact model translates onto Orbit's profile and audience model with a small, reviewable diff. Bot-flow export to Orbit Flows: Fin's answers become knowledge articles and flow steps, and the hand-off points become squad hand-offs to the human desk. Then a staged cutover week, never a big-bang weekend.
The field-mapping diff, condensed to the lines that decide the import:
# Intercom contact -> Orbit profile
- custom_attributes: { plan_tier: "pro", ltv_band: "high" }
+ custom_fields: { plan_tier: "pro", ltv_band: "high" }
- tags: ["vip", "churn-risk"]
+ audiences: ["vip", "churn-risk"] # tags become queryable CDP audiences
- owner_id: 512 # a seat id; seats do not exist on Orbit
+ team: "support-emea" # routing moves from person to teamThe staged cutover calendar, one week, each day reversible:
- Mon: import contacts and history; Orbit runs shadow next to Intercom, no customer-visible change.
- Tue: port the web widget; new conversations open in Orbit, old threads stay readable in Intercom.
- Wed: move email; verify opt-out and quiet-hours policy per market before the switch.
- Thu: activate SMS and WhatsApp senders; run the consent checks the runbook lists.
- Fri: forward the support line; the AI agent answers with human hand-off live from day one.
- Weekend: Intercom read-only; export retained for the agreed window; retro on Monday.
5. Where NOT to switch
A small US team whose support lives in the website widget and the email queue, with no SMS or voice programme planned, should stay on Intercom. On Essential at $29 a seat, five agents bill $145 a month for a mature helpdesk with a native Fin bot, and a CPaaS's per-message meter buys that team channels it will not send on. Orbit's economics start earning their keep at the first phone line, the first WhatsApp sender, the first seat hire that exists only because volume grew. If none of those is on the roadmap, the honest answer is that the helpdesk is the right tool, and this post is for the quarter that changes.
Frequently asked questions
Is Devotel Orbit an Intercom alternative?
Yes, for teams whose customer conversations extend past the widget: Orbit ships the shared inbox, the AI agents, and the channel set on one usage bill. For a widget-and-email team under five seats, Intercom remains the purpose-built choice and this post says so plainly.
How does Fin pricing compare to Orbit's AI agents?
Fin bills $0.99 per resolution on top of seats, retrieved from Intercom's pricing page on 16 October 2026. Orbit's AI agents are a platform surface: an AI-handled conversation bills its message segments, call minutes, and tokens on the published rate card, with no per-resolution meter and no seat underneath it.
Can we keep Intercom and add Orbit for SMS and voice only?
Yes, and the runbook's staged plan supports a channel-first cutover that leaves the helpdesk in place for a quarter. Most teams that start there finish the migration once the conversation history splits across two systems; plan the hybrid as a stage, not an architecture.
Does Orbit's inbox support AI with human hand-off?
Yes. A squad classifier routes each turn to a specialist agent or the human desk, and sensitive tool actions wait for an operator approval before they execute; the Fin alternative post walks the agent-scope question in detail.
