Now getting paid for a meeting is as easy as booking one
Key takeaways
- Cal.com now lets users accept payment natively at booking time using Whop's embedded checkout components.
- Native payments eliminate external checkout handoffs that caused over 22% of customers to abandon purchases.
- Whop's embedded components let platforms offer native payments without building payment infrastructure from scratch.
Every coach, consultant, and doctor on the internet has a booking link. Getting paid through that link is the tricky part.
Cal.com just changed that.
Founded in 2021 by Bailey Pumfleet and Peer Richelsen, Cal.com is the open-source alternative to Calendly: scheduling infrastructure, as they call it, for absolutely everyone. Over 20,000 customers use it today, from independent coaches to DoD subcontractors to enterprise teams.
Now anyone using Cal.com can get accept payments, in app, at the time of booking – with Whop embedded components.
Getting paid for your time upfront
For Cal users who charge for their time – therapists, financial advisors, consultants – the ability to take payment at the time of booking is crucial. The alternative is an invoice sent after the fact. And invoices are consistently paid late.
According to Intuit QuickBooks' 2025 Small Business Late Payments Report, 56% of US small businesses are currently owed money on outstanding invoices. When you're a small business, cashflow is crucial.
Getting paid for bookings on Cal isn’t new, but getting paid natively is, with Cal Payments.
Before Cal Payments, users who wanted to charge for their time had to navigate to the app store, install an integration, connect an external account – a separate signup if they didn't already have one – and complete an OAuth flow before their booking link could collect a single dollar.
And once a client went to pay, they were handed off to an external checkout page. That handoff costs sales: more than 22% of customers abandon at checkout if the process is too long or complicated.
So imagine that you’re a coach whose entire business runs on a booking link. That drop-off could lead to a lost client. And for Cal, that transaction generated zero gross profit regardless of whether it completed or not.
Cal Payments, powered by Whop
Cal has now launched Cal Payments, a native payments layer built on Whop's embedded components.
When a Cal user sets a price on their booking link, Whop's embedded checkout loads natively inside the booking experience. The client picks a time, sees the price, and pays – by card, ACH, bank wire, crypto, or Cash App – without leaving Cal, without a Whop account, and without any OAuth setup on either side.
KYC is required at payout, not at setup. Hosts see their balance directly inside Cal and withdraw through Cal Payments. And the whole flow lives in one place.
For Cal users, that means paid bookings are finally as easy as free ones. For Cal, native payments means upgrading from SaaS to fintech, as the platform can now earn revenue on every paid booking.
"Very happy for this partnership. Technically was a breeze to integrate."
