ReplyKit vs Intercom's Fin: the enterprise AI agent priced per resolution, against a flat-price WhatsApp agent for small businesses

Intercom's Fin is one of the strongest AI support agents on the market, used by software companies and large support teams, and priced per resolution. ReplyKit is a WhatsApp and website AI agent for small businesses, priced per month. A clinic or a salon comparing the two is really comparing a helpdesk to a receptionist. Here is the honest version.

Quick answer

Choose Intercom and Fin if you run a support team with a helpdesk, knowledge centre and many channels (email, chat, WhatsApp, voice) and can budget per-resolution AI pricing (about $0.99 per outcome) on top of seat plans from about $49 a month; in June 2026 Intercom announced an agreement to be acquired by Salesforce, so check the current terms. Choose ReplyKit if you are a small business on WhatsApp that wants AI replies, booking, a CRM and a website assistant for a flat $29 to $99 a month with no per-resolution fees. ReplyKit is $29, $49 or $99 a month with AI replies included (1,000, 5,000 or 20,000 a month), connected through Meta's official WhatsApp Business Platform with no pairing risk, a website assistant, booking, a CRM and inbox, and a 7-day free trial with no card. Meta's per-message fees apply only to reminder and follow-up templates sent outside the 24-hour window.

Where Fin wins

Fin's pricing is on its pricing page. For a large support volume the per-resolution model can be efficient; for a small business it is a variable bill on top of seats.

Where ReplyKit wins

Where the connection matters: ReplyKit runs on Meta's official WhatsApp Business Platform, so there is no linked-device pairing and no restriction risk from automation. Meta's per-message fees apply only to reminder and follow-up templates sent outside the 24-hour window; replies to customers who message you carry no Meta fee inside it. The trade-offs are explained in why ReplyKit runs on the official platform.

ReplyKit plans: Starter $29 (1 number, 1 agent, 1 website assistant, 1,000 replies), Growth $49 (3 numbers, 5 agents, 5 website assistants, 5,000 replies, follow-up nudges), Pro $99 (15 numbers, unlimited agents, 20,000 replies). Extra replies are $10 per 1,000. AI is included, and Meta's message fees apply only to reminder and follow-up templates. Details in what it costs.

How we know this. We compared Intercom and Fin's published September 2026 pricing with ReplyKit's plans; Fin is aimed at a different customer and we say so rather than pretend they compete on every point. Product figures in this article (limits, prices, per-reply costs) are taken from ReplyKit as it runs today and are re-checked when we update the page. Where we cite outside research, the source is linked below. We sell ReplyKit, so read our product claims with that in mind; we say where a different tool or no tool is the better choice.
