What we don't build

Most product pages are a list of what a tool does. This is the other list. Every capability below is something Calendaty does not have, said plainly, because the alternative is that you find out in week two with your whole diary already moved across.

The same list appears on six industry pages, on both comparison pages and on the features page. This is the one place that explains why each item is on it.

It is not a preview of a roadmap. Nothing below is described as being on the way, because a gap dressed up as a plan is still a gap, and the reader is the one who pays for the difference.

Money: no deposits, no packages, no credits

There are no deposits and no partial pre-payment. A service is charged in full at booking, or it is marked pay-locally and still tracked to the appointment. There is no partial hold, and no middle amount sitting between the two.

There are no packages, credits or memberships either. Ten sessions are ten bookings, each paid on its own, not a balance counting down. Both are absent for the same reason: a partial charge and a credit balance are ledger problems, not booking problems. Each needs refund rules, expiry rules, transfer rules and a statement the customer can argue with, and a booking product that implements a third of that is worse than one that does not implement it at all. What protects a high-value slot instead is the change-lock window, which costs the customer nothing and costs you nothing to run.

Time: no recurrence, no group capacity, no waitlists

Services do not recur. The client who comes every fourth Saturday rebooks each time, or you create the sessions from the dashboard — which takes seconds, and has the side benefit that a standing slot never quietly outlives the arrangement behind it.

And there is one appointment per slot. No attendee limit, no capacity, no waitlist. A class can be blocked out as a single booked slot, but the platform will not count or cap who is in it — you do that yourself, on paper or wherever you do it now. If capped group classes are the business rather than a sideline, this is the wrong tool, and no amount of blocking out slots will make it the right one.

Channels: no SMS, no WhatsApp, no Instagram

Reminders and follow-ups to your customers are email. Alerts to your staff go to Telegram, Slack or your own webhook. The agent itself works in web chat on your booking page — not on WhatsApp, Instagram or Telegram.

• Instead of SMS reminders: email reminders and follow-ups, plus a booking alert pushed to your own Telegram or Slack the second it lands.
• Instead of a WhatsApp agent: put the booking link in your WhatsApp Business profile and let the conversation carry on there.
• Instead of an Instagram agent: the link in the bio, and the individual service page linked from the post that is meant to sell it.

SMS is absent because it is a per-message cost with per-country rules that would have to be priced into every plan, and a booking product should not quietly become a telecoms reseller. WhatsApp and Instagram are absent for a different reason: both are gated business platforms with their own approvals, message templates and messaging windows, and an agent that somebody else's policy review can switch off is not something to build a front desk on.

Records and planning: no clinical records, no resource allocation

Calendaty is not an EMR or an EHR, and it is not sold as a HIPAA-compliant clinical system. It books the appointment, captures your intake fields with it, and stops there. Clinical notes belong in a clinical system, and a booking tool that starts storing them without the compliance regime around them is a liability wearing a feature's clothes.

Nor is there project or resource planning: no capacity planning, no timesheets, no multi-day allocation. An appointment here is one person, one service, one slot. If your work is allocating people across weeks, that is a different shape of problem and a different category of tool.

Why this list is published at all

Publishing your own gaps is unusual, and the reason is not modesty. A booking platform is chosen once and then everything else is arranged around it — your services, your prices, your staff, your customers' habits. The cost of discovering one of these eight items in month three is not the missing capability. It is the move.

A limit you read on the way in costs a decision. The same limit found in week two costs a migration.

It keeps us honest in the other direction too. Six industry pages, both comparison pages and the features page render this same list, so no item can be softened on one page and left standing on another. If any of it ever changes, this post is edited in the same change — or the site starts arguing with itself.

If that is your business, we are the wrong tool

That sentence is meant literally, and it is the most useful thing on this page. If you run capped group classes, sell session packs, or need standing weekly slots created for you, the honest recommendation is a tool built for those things. You will be happier, and we will not have cost you a month.

And if you need a clinical system, or stock and retail, keep the tool that does it and run Calendaty as the booking layer alongside it. That is a common and sensible setup, not a compromise. What is left after all eight of these is one narrow thing done properly: one person, one service, one slot, booked and paid for inside a conversation.
