On Oliverlist, each completed appointment is considered billable 24 hours after the start time of the appointment, if it has not been reported as out of scope or absent.
Regarding collections on Oliverlist:
We bill you each time your account reaches a certain amount, called the payment threshold, or exactly the same day of the month as your last automatic debit (whichever of these two events occurs first). The payment threshold corresponds to a ceiling, which, when exceeded, triggers the collection of this same amount. This amount is initially fixed at €300 and will be automatically increased in increments of €100 if it is exceeded before the end of the monthly billing cycle.
Regarding billing on Oliverlist:
Oliverlist issues an invoice for each debit, according to the conditions stated above.
You can find all your invoices in the "Settings" -> "Billing" -> "Invoices" section.
