# Sauna membership software

A subscription bills a card every month. A membership changes what a person does on a Tuesday. Only one of those keeps a recovery room full.

If your room lives on first visits and walk-ins, you do not need membership software. A recurring-billing toggle on a cheap scheduler is enough. If a meaningful slice of revenue is people who come back on a rhythm, the membership is a promise: member seats, founding prices, guest-pass limits, and a wallet that turns a cancellation into a return visit.

## Short answer

Zettlor treats a membership as a right of way, not only a recurring charge. Access rules can hold member seats before drop-ins book them, while shared drop-ins and private room buyouts still draw from the same physical room inventory. The same membership can carry more than one price so founding members keep their rate. A visit membership can include a fixed number of [sessions that reset](/guides/membership/included-sessions) on the Stripe billing date, such as 8 sessions per month. Unused sessions do not roll over. Punch packs and gift cards keep a remaining balance until use or expiry.

## When you do not need this

If your sauna or cold plunge business is mostly one-off walk-ins, tourist day passes, or private group rentals with no recurring cohort, a simple scheduler with Stripe payment links is enough. Membership software earns its keep when repeat visits are the floor under your monthly revenue.

## Why generic schedulers break

- **Shared seats, member holds, and private buyouts on one room**: Generic schedulers treat memberships as coupon codes on 1:1 appointments. Zettlor holds member seats against [shared-capacity room inventory](/guides/booking/shared-capacity) while allowing [private sessions and space buyout locks](/guides/booking/private-vs-shared-same-slot) (with [upfront deposits](/guides/pay/deposit-then-balance), checkout add-ons, and [host-paid rosters](/guides/pay/host-pays-before-names)) on the same room without double-booking.
- **Separate membership agreements and session waivers**: Operators can require both a session liability waiver and a separate membership agreement (or cold-plunge acknowledgment) using per-offering `Requires Waiver` and [multiple waiver templates](/guides/desk/more-than-one-waiver). Zettlor collects payment first so checkout never stalls, prompts immediately for signatures or [door QR / kiosk signing](/guides/desk/waiver-web-or-door), blocks self check-in until signed, and shows signed status on each guest row on `Schedule` ([seeing signed waivers](/guides/desk/see-signed-waiver)).
- **Front-desk POS on your own Stripe account**: Subscriptions, saved cards, and payouts live in [your own Stripe account](/guides/pay/own-stripe-account). At the register, staff charge saved cards on file, Stripe's in-browser card form (with phone tap-to-pay where supported by the browser), [retail cash](/guides/pay/offline-payment), or [door QR self-checkout](/guides/desk/qr-poster) without requiring dedicated countertop Stripe Terminal hardware ([front-desk card checkout](/guides/pay/stripe-reader)).
- **Assisted migration with zero second checkout**: When switching from Acuity, Momence, Mindbody, or Vagaro, Zettlor combines team-assisted migration with `Advanced -> Import` and `Advanced -> Migration` staging: customer CSVs are deduplicated by email and phone (`Merge Customer` includes undo), [existing Stripe subscriptions link directly to customer profiles](/guides/membership/port-existing-membership) so active members never re-enter their card, [remaining punch-pack visits and gift card balances load onto profiles](/guides/migrate/gift-card-balances), and [future bookings](/guides/migrate/future-reservations) are placed before you flip the live calendar ([full migration checklist](/resources/migrating-sauna-memberships-and-credits)).

## What to evaluate

- Ask the vendor to hold a window of member seats at 6pm before drop-ins can book them, then raise the rack rate while founding members keep their old price.
- Verify that existing Stripe subscriptions, punch packs, and gift cards port over without asking members to re-enter cards: [porting existing memberships](/guides/membership/port-existing-membership).
