Cal.com, IncReviews of cal.com

A useless tool — everything is laggy. Support never actually tries to help. You wait 3 days for a response, only to get template replies; they don’t even try to understand the issue. If your business requires anything more than booking a video call, know this: you’re left completely on your own with your problem.

We really wanted to like Cal.com, and from a product point of view it’s close. Unfortunately, the invoicing and billing side makes it unusable for a serious business. Despite having correct company details attached to our account from day one, invoices keep getting issued to a private individual name. Support acknowledged the issue, said it was fixed, but weeks later the same problem still happens. Another issue is that invoices cannot be reissued. That’s simply not acceptable for a EU-based company that needs correct accounting documents. On top of that, invoices are only accessible via email. There is no invoice history inside the app. Emails sent by Cal often end up in spam, which makes bookkeeping unnecessarily painful. Competitors like Calendly handle this much better. Support responses are slow, fixes don’t stick, and the overall feeling is that billing is treated like an afterthought. The product feels more like a prototype than a tool ready for real businesses. We like the idea of Cal.com and would love to keep using it, but basic things like correct invoices and proper billing access are non-negotiable. Until this is fixed, we’re forced to look elsewhere. 2 stars because the core scheduling itself is solid.

Grate experience!!

Awesome app and allows for customizing the colors to fit our brand. Loving it and their customer support replied quickly to a small issue we had

Tech support FTW! They figured out the setting I needed to change and got me up and running super quick!

We’re incredibly grateful that Cal.com exists. It has become a key part of how we let our customers book our first-aid courses, and it has made our entire scheduling process smoother, faster, and more reliable. What truly sets Cal.com apart is the support. We’ve accidentally hit the API limit more than once, and José has repeatedly helped us get unblocked with impressive speed and patience — always friendly, always solution-oriented, and honestly as if it were the most normal thing in the world. That kind of consistent, human support is rare. We’ve also shared a few suggestions and feature requests along the way, and they were welcomed openly. You really get the feeling that Cal.com listens, cares, and continuously improves — and that you’re in good hands as a customer. On top of that, Cal.com offers excellent value for money: a powerful product, dependable APIs, and truly first-class customer service. We’re extremely satisfied and can wholeheartedly recommend Cal.com to anyone who needs a professional scheduling solution with top-tier support behind it. Marc from Lehrer-Spezialisten.de

Cal.com is amazing! The project is super solid but fluid in the same time, and what really stands out is the team and community, dedicated, helpful, and passionate. That energy comes in every update, and it makes using Cal.com a genuinely great experience.

Superb scheduling software! After dealing with the mess and issues of Calendly, I found Cal.com on a search and so glad I did. 2-way syncs with Outlook perfectly, and easy to use and setup. The in-person locations were a little confusing, but support walked me through. All good and all setup with scheduling software that works.
