Can you run 20 appointments a day on free booking software, or what's the catch?

I started with a free booking tool at a similar volume, handling about 450 appointments a month. On top of the standard bank fees for payments, the software took an extra cut of 1.5 euro per transaction. By the end of the month, I’d lost over 600 euro to the platform. The very next month, I switched right over to a fixed-rate system for 35 euro a month.

Watch out for calendar sync issues. Most free plans don't use real-time webhooks with external calendars; they use ICS feed links. External calendars sometimes only refresh those feeds hours later. Even if you book an appointment over the phone during that gap, the system still thinks you're free and lets someone else book online.

There’s no such thing as truly free software in the booking industry. Companies don't cover server and SMS costs out of the goodness of their hearts. Unless the contract explicitly guarantees they won't pull your clients into their marketplace and recommend the competitor down the street, you're basically handing over your client list for free.

Check the terms of service for two main things: whether you can export your client list and booking history as a CSV, and if SMS reminders are included. If the free plan doesn't offer these two features, don't even bother; migrating to another platform later will be a massive headache.

20 sessions a day is a seriously intense pace, props to you. but at that volume, even a single client ghosting you means losing a full sessions income then anyway free systems usually lock features like pre-authorization or mandatory deposits to prevent no-shows, so keep that in mind from the get-go.

Edit: asked below, I wrote the answer in the second message.

rgpd rules in france are super strict too. tbh most free tools host their servers outside the eu or spam clients with their own ads without consent. if a client complains down the road its an unnecessary headache better to stick with a professional setup from the start.

Out of the 20 bookings you handle a day, how many are recurring clients versus first-timers? If it's mostly your regular client base, wouldn't a simple, one-time booking module integrated directly into your website be a much cleaner solution?

we were thrilled to set up a "free" system until the first month, when we saw it sending SMS discount codes for the business next door to our clients—huge wake-up call and with free software, if you aren't the product, your clients definitely are.

I went through the same thing.

We've heard this a lot, but it never happened like that for us. The system lives on after delivery; maintenance is a separate line item.

This is my opinion, I'm not claiming it's absolute truth.

I agree.

We need to make a distinction here. Everything goes well for the first three months; problems arise in the fourth.

Just leaving this note, it might be useful.

let me clarify the technical side. just because everyone does it doesn't mean it's right.

hope this helps.

We need to take it step by step. If you don't write this down from the start, it leads to arguments later.

Just leaving this note, it might be useful.

If I understood correctly, you're saying: Everything goes well for the first three months; problems arise in the fourth.

If I were you I'd go this route.

you're right and solutions that work at a small scale collapse when you grow; I learned this late.

proven by experience.

Following.

Thanks for writing this, that's the right way. Any unwritten clause becomes a point of disagreement later, as both sides remember it differently.

Most time waste accumulates in tasks waiting for approval. That's all, sorry if I went on too long.
