Balance on arrival: the part of the fee the deposit left open, settled once she is inside, in cash of a major currency, by card or in crypto.
A booking's fee arrives in at most two parts. The first, where a booking carries one, is the deposit, settled electronically before she sets out. The second is the balance, paid when she arrives and before the session begins. Settling at the outset means the time that follows contains no transaction at all.
Half the fee, which is the ordinary case. On a first booking of two hours with one therapist, one hour's worth went ahead and one hour's worth is the balance.
The whole fee, which is the exception. A returning client asks for one or two hours today, nothing is sent in advance, and the full fee for that hour or those two becomes the balance.
A figure already reduced by a deposit carried over. Where the house could not perform an earlier booking and the client chose to leave that deposit with it rather than take it back, the sum counts as paid, and the balance on the later booking falls by the same amount.
Every figure is a euro figure, and the euro figure is the price. Banknotes in another major currency are accepted too, and the exact amount in that currency is confirmed to you in writing before she sets out, so pounds, dollars or francs carried from home need no exchange first. Card works. Crypto is accepted as well. The method need not match the deposit's: an advance sent through Wise can be followed by a balance in banknotes.
The balance is written in the thread at confirmation, beside the deposit where one applies, so there is nothing to calculate at the door. Amounts in the rates table on each therapist profile are full fees; halve one to find the ordinary balance. The FAQ answers questions about currencies and cards.
