Offer subscriptions online with a deposit (and process the balance at the first treatment in the salon) and offer the possibility to schedule all treatments (or the first if the settings) online during this reservation.

In automatic cancellation mail, if the deposit has not been paid, state that it was therefore canceled because the customer did not pay the deposit, otherwise it is confusing

If a customer asks you to add a certain treatment, you can't currently add it to an existing booking via the smartphone.

When a customer has a subscription, he/she would be able to book online without paying a deposit.
