The balance on arrival is the share of the fee still owed when she comes through the door, settled once, at the outset, with banknotes, a card or crypto.
A booking is paid in one or two parts. Where a deposit has been placed, the balance is the other half. Where no deposit applied, the balance is the whole price. Either way it is handed to the therapist in person, at the start of the visit, so that the matter of money is closed before the session begins and does not sit in the room waiting to be raised at the end.
At the door, three forms of payment serve. Banknotes may be euros, dollars, pounds or any other major currency, reckoned at the rate of the day, which spares a visitor a trip to an exchange counter. A card works equally well. Cryptocurrency is accepted too. Nothing needs to be chosen in advance, although mentioning the method in the thread saves a moment later.
There is one kind of booking settled entirely on arrival, and it is narrow: a same-day massage lasting an hour or two, for someone the house already knows from an earlier booking. It is a side door, not the main one. A first booking is not included, nor is a booking placed more than a day ahead, an overnight, anything running to three hours or beyond, two therapists, a companion format, a Schiphol or airport-hotel visit or a peak date. Each of those carries a deposit, and for each of them the balance is the second half.
Two figures make the difference plain. A returning client asking for ninety minutes tonight hands over EUR 270 when she arrives, and nothing beforehand. A client booking the same ninety minutes for the first time places EUR 135 ahead and pays EUR 135 on arrival. The deposit entry lists every case that requires one, the price page gives the ladder, and the order of messages is on the booking page.
