Get paid when the appointment is booked, without chasing payments later

Your client can pay for the service at the exact moment they book, directly from their portal. Payments are processed through Stripe and automatically linked to the appointment, the activity and the invoice.

Payments under control, not under guesswork

The payment is part of the booking, not a separate step

It is not a standalone gateway: it connects the payment with the client, the service, the calendar and invoicing.

Pay at booking

Clients pay for the service at the exact moment they book the appointment, without separate links or extra steps.

Fewer unpaid appointments

The service is already paid for by the time the appointment arrives, without depending on the client remembering or you having to ask.

Secure payments with Stripe

Payments are processed through Stripe, one of the most widely used and secure online payment providers.

Linked to the appointment

Every payment is automatically linked to the appointment and the activity it generates, with nothing to match up by hand.

Automatic invoicing

With the payment already linked, SIKIO can issue the corresponding invoice or simplified invoice, if that's what you choose.

Real income, not estimates

You always know what has been collected and what is still pending, without checking two or three different places.

Profitability with Expenses

Combined with the expenses module, you can easily see what's left from each service after your costs.

No extra tool

The payment gateway is included in SIKIO; there is no need to contract or manage a separate payment provider.

Built for Teams

With Teams, each professional's payments stay just as connected to their own calendar and activity.

How it works

From booking to confirmed payment

Choose which services require payment in advance

You decide which services turn on payment at booking time.

The client pays when booking

They book their appointment and pay in the same step, securely with Stripe, from their private space — whether they're a regular client or booking with you for the very first time.

Everything stays connected

Appointment, payment, activity and invoice remain linked in SIKIO, ready whenever you need them.

Payments and invoicing

More context than an isolated payment

SIKIO connects the payment with the rest of the professional relationship, not just the appointment.

Without a built-in gateway

Payment depends on the client paying during the appointment or afterwards.
You have to chase payments and match them to appointments by hand.
Invoicing happens separately, checking what has been collected.
You need another tool or process just to collect payments online.

With SIKIO

Clients pay when booking, securely with Stripe.
The payment is automatically linked to the appointment and the activity.
The invoice or simplified invoice is generated automatically.
All your income, in the same place where you manage your business.

Frequently asked questions

Questions about SIKIO's payment gateway

Is payment in advance mandatory?

No. You decide which services turn on payment at booking time; everything else can keep working as before.

Which payment gateway does SIKIO use, and is it secure?

Payments are processed through Stripe, one of the most widely used and secure online payment providers on the market.

Does the payment automatically generate the invoice?

Yes, if that's what you choose. The payment is linked to the appointment and the activity, and SIKIO can automatically issue the corresponding invoice or simplified invoice.

Does it also work for new clients booking for the first time?

Yes. There is no need to add them beforehand: when someone discovers you and books for the first time through your online calendar, they book their appointment and then complete the payment, exactly like a regular client.

Can I see my real income, not just what I've invoiced?

Yes. With payments built into the same platform, you always know what has been paid and what is still pending, and you can combine it with the expenses module to see the real profitability of each service.
