How do I book a complimentary session?

Staff book a walk-in or reservation at $0 when a credit covers the seat, or grant a complimentary credit first.

ZettlorUpdated August 26, 2026

Staff book the complimentary sauna or cold plunge seat at the desk so checkout is $0 when a credit covers it, or after a complimentary grant. Public checkout still creates a reservation; it is $0 only when spendable credit covers the seat.

What Zettlor does today

Staff walk-in and reservation flows can complete at $0 when session or dollar credits cover the price, or when staff choose complimentary on the walk-in pay path. A public guest without cover still sees a price.

This behavior is live in Zettlor today for a commercial sauna and cold plunge room. Guest booking, cancel, and credit self-serve steps stay on Help. This page is for operators.

Desk path

Grant a complimentary credit if they have none, then book the slot from Schedule or walk-in. Walk-in pay supports now or comp; do not invent a complimentary-session toggle on the offering.

Do not invent a settings path beyond what is listed here. If the product does not include a control, the desk workaround is the path.

Failure mode

Desk clicks the public booking page, pays $0 expecting a hidden complimentary product, and either fails payment or consumes the last seat without a customer credit record.

Operator example

Alchemy comps a first-timer cold plunge after a tour. Staff grant one session credit, then walk them onto the in-progress slot so the reservation shows paid with credit.

A sauna and cold plunge operator can copy the shape of this example without copying another brand's private pricing or customer lists.

How to do this

  1. If the guest has no cover, grant a complimentary credit on the customer.
  2. Open Schedule and book the sauna or cold plunge slot as staff.
  3. Use walk-in comp or let the credit cover the seat to $0.
  4. Confirm the attendee is on the reservation before they enter the room.

Can the guest self-book a free session without credit?

Public checkout charges the session price unless spendable credit covers it. Staff comp is the desk path.

Does comp consume capacity?

Yes. A complimentary seat still occupies session capacity like any other reservation.
