Service bundles

Sell the full journey, not one appointment.

Create an offer such as 20 appointments to use within three months. Your client buys once, receives a private booking link and schedules each included session while Zencal tracks the remaining limit and expiry date.

What are service bundles in Zencal?

Service bundles in Zencal let a client buy several appointments in one purchase. The bundle defines the number of uses and validity period, then gives the client a private link for scheduling the included sessions.

Best for: Long-term therapy, mentoring programmes and multi-session services
Replaces: Selling and tracking every session separately
Core outcome: Sell a high-ticket offer and receive payment upfront, while your client gets convenience and an attractive price

The problem it solves

A service outcome often requires more than one appointment. Selling each session separately forces the client to repeat the process several times. Enabling clients to buy a bundle reduces their effort and increases sales for your business.

Legal, data and technical detailsbefore moving to Zencal.

Review data processing terms, infrastructure location, available integrations and the technical conditions of migration before implementation begins.

Do I have to move my entire calendar?

No. Connect your current Google, Outlook or iCloud calendar and keep using it as before. Zencal checks for conflicts and adds new bookings to the connected calendar.

Which calendar and payment integrations are supported?

Zencal connects with Google Calendar, Outlook and iCloud. Supported payment providers include Stripe, PayU, Przelewy24, tPay, PayPal and AutoPay. Each connection can be introduced without replacing the rest of your technical setup.

How can existing client data be migrated or exported?

Connecting a calendar does not require rebuilding it. Client data can be imported and exported, and our team can help plan a larger migration before making any client-facing changes.
