Service for the sale of tickets. Does something similar exist?

Question

Electronic commerce

Let's say there is a recording studio, recording a phonogram in which it costs (conditionally) 2000 rubles.
Payment is made only online. Buyer's funds are initially "reserved". Payment takes place in two stages:
1 - purchase of a recording time ticket (a certain receipt indicating the time and date of the recording, selected by the buyer, and a barcode, on the basis of which the system writes off in favor of the studio 1000)
2 - after the track is mixed, the studio puts ready-made materials for sale for 1000 and, if the client is satisfied with everything, he writes off the reserved balance in favor of the studio
. If the client does not come to the studio, the funds are returned to him in full.
Is there something similar?

Answer 1

You've made a discovery: a digital good.
Feel HostCMS - out of the box there are both digital goods and internal currency, and even (which is not related to the topic at all) - barcodes !!...)))

Answer 2

Plati.ru - look at the subject of what can be sold.
