The customer chooses towels, drinks and treatments at the same time as the sauna session. Everything comes on one order, so you know in advance how many towels and which drinks the session needs.
Treatments only when there's time for them
A treatment has its own availability, so the customer can only buy it for a time when a treatment slot is available.
Online and at the POS
You sell the same add-on services and sauna products on site with Johku POS, and the sales are recorded in the same Johku as your online store orders.
