Online Appointment Scheduling Software.
a calendar entry.
Between "When are you free?" and "See you tomorrow!" sits a chain: calculate free time, book, confirm, remind, review. Slotara runs that chain — for every single appointment.
Five stations. One flow.
Every Slotara capability sits at one station of this chain. None of it is a loose feature — everything works on the same appointment.
-
1
Availability.
From weekly schedules, existing appointments, absences and buffers, Slotara recalculates what is genuinely free on every request. There is no maintained slot inventory that could go stale.
-
2
Booking.
Your clients pick service, person and time themselves — on your booking page or in the widget on your website. The slot is occupied in the calendar immediately.
-
3
Confirmation.
The confirmation goes out instantly by email — with a calendar entry (.ics) your clients can import into their calendar.
-
4
Reminder.
Before the appointment, Slotara reminds exactly once by email — at the lead time you configure (default: 24 hours).

Insights.
Completed, cancelled and missed appointments land in your reports — you see what actually happens in your calendar.
Seven jobs. An answer for each.
In short: what Slotara handles where — and where to go deeper.
Online booking
Appointments happen in the evening, on weekends, on the go — not only when someone at your business can pick up.
Your own booking page under your name plus an embeddable widget for your website. Your branding, no marketplace.

Who can do what — and who is actually in when?
If you assign qualifications to a service, it is only offered with suitably assigned team members. Weekly schedules reflect real days — including multiple working windows.
See team managementConfirmation & reminder
Agreed appointments get forgotten — and you end up phoning after them.
Instant confirmation email with a calendar entry (.ics), plus one automatic reminder at your lead time.
See remindersPayment at booking
If payment is only settled after booking, an extra step appears in the flow.
If you enable payment at booking for a service, your clients pay right inside the booking flow. If you don't, the booking flow stays without a payment step.

Two branches, two systems, double the upkeep.
Multiple locations with their staff and service assignments in one Slotara environment — including location selection in the booking flow. Depending on your plan.

Busy is not the same as well utilised.
Booking volume, utilisation and missed appointments — as answers to business questions, not a graveyard of numbers.

Slotara should fit your website and your workflows — not the other way around.
Embeddable widget, a calendar entry in every confirmation, REST API and webhooks in the larger plans — activated per business.
See integrationsYour weekly schedule has gaps. On purpose.
A real working day is rarely one block from eight to six. Morning on site, closed at lunch, two more hours in the evening — in Slotara you create multiple working windows per person and day. Only what falls inside a window is bookable.
In between, nothing is bookable by design: the break stays a break, and the evening block starts when you say so. Nobody has to appear continuously available just to be bookable online.
Who was in, and when? It's on record.
Every booking belongs to a customer record: name, contact details and past appointments — in one place instead of a paper tray and an inbox. When someone calls, you can look up their details and past appointments right away.
Free times are calculated, not maintained.
Slotara stores no list of free slots that anyone would have to keep current. On every request the system recalculates: working windows minus existing appointments minus absences minus buffers — what remains is what is genuinely bookable right now.
Every booking is checked against the calendar of the chosen person. Anything that would collide is never offered — and a booked slot is occupied immediately.
