"Für Interessenten buchbar" — the hidden checkbox
If you’ve set up a public form and it shows zero available slots despite the calendar being full of bookable time, this is the cause 95% of the time.
What the checkbox does
Section titled “What the checkbox does”Every individual resource slot has a “Für Interessenten buchbar” (bookable by prospects) checkbox. By default it’s off.
When off, the slot is:
- Visible in the internal console (operators can book it manually).
- Invisible to any embedded form or public booking surface.
When on, the slot is offered to prospects through forms and the public booking flow.
This is per-slot, not per-resource. Creating ten slots and forgetting the checkbox on any of them means those ten won’t appear in public bookings.
Why it works this way
Section titled “Why it works this way”The product distinguishes between internally schedulable and publicly bookable availability. A coach’s full work schedule is internally schedulable — they can be booked by the office staff into a Monday-morning team meeting, for example. But you might not want to offer that whole window to prospects via the website form; only the slots you’ve actively marked as “open for trial booking” should show up there.
The checkbox is what makes that distinction explicit.
How to set it
Section titled “How to set it”- Open the resource planner.
- Click a slot.
- Tick “Für Interessenten buchbar” in the slot details.
- Save.
- Repeat for every slot you want public.
If you have many slots and want to ship the form fast, batch-edit by selecting multiple slots first (depending on the planner UI version).
Form configuration is separate
Section titled “Form configuration is separate”The form widget has its own appointment-type filter — you choose which types the form offers. So there are two flags:
| Flag | Where | What it controls |
|---|---|---|
| Form’s appointment-type list | Form widget settings | Which types appear as options on the form |
Für Interessenten buchbar | Per-slot, in the resource planner | Whether each slot of those types is offered |
Both must align. A form configured to offer “Probetraining” but with no slots marked Für Interessenten buchbar shows the type but no times.
Future improvement
Section titled “Future improvement”A planned form-editor warning will flag this case: “You’ve selected appointment types X, Y, Z but no slots of those types are marked bookable by prospects.” Until that ships, this article is the safety net.
Troubleshooting checklist
Section titled “Troubleshooting checklist”If a public form shows no slots:
Für Interessenten buchbarticked on at least one slot of each offered appointment type? ← start here- Are the slots actually in the future?
- Is the appointment type linked to the resource that has the slot? (Mismatched resource ↔ appointment type breaks search.)
- Is the form configured to offer those appointment types?
- Are there blockers covering the visible date range?
In that order. 95% of the time it’s step 1.
