Calendly is quietly becoming a CRM with a payment terminal and an agent-facing API.
Scheduling is no longer where Calendly's releases land. The last two months added contact profiles with custom fields, lists and note reminders; multi-session Meeting Packages sold with upfront payment; standalone Payment Links that work without a booking at all; and a Claude connector that exposes event types, availability and booking to an assistant. Each of these sits beside the calendar rather than inside it.
Help Scout keeps adding channels — now a portal customers sign into
Two customer-facing surfaces landed in a week: two-way SMS through a customer's own Twilio number, and a Customer Portal where a company's contacts sign in to see support history raised across their organization. Underneath, the SLA system built out in May and June now drives workflows, views, and reporting. Per-inbox office hours, away auto-reassignment, and availability status on web and mobile fill in the operational layer.

Each of these sits beside the calendar rather than inside it.
Two expansions are running at once. Calendly is building the lightweight relationship layer its users previously kept in a CRM — fields, lists, follow-up nudges — and it is moving from collecting payment for a booking to collecting payment as its own action. The Claude connector points the other way: the booking flow becomes something an agent drives while the human stays in a conversation.
The contact object is the piece everything else can hang from, so expect follow-up automation and segmentation to build on lists and custom fields next, and payments to keep detaching from the booking flow. Whether the agent connector stays a convenience or becomes the primary interface is not something these entries can settle.

The product is widening from an agent-side inbox into the places customers actually wait — SMS, WhatsApp, and now a signed-in portal with company-level visibility. Portal access sitting on Plus and Pro puts the newest surfaces on the paid tiers rather than across the board.
Expect the portal to pick up what adjacent surfaces already have — SLA status, more self-serve actions — and the channel list to keep widening rather than any one channel getting deeper.
