What is the name of such non-standard functionality based on an online store?

Question

Online shopping

Colleagues, tell me, what is the name of such a solution, in order to understand where to dig?

For example, we are selling a jacket and the product card indicates that the seller will start sending out jackets to customers when this jacket is bought 30 times. In the meantime, the number of orders is less than 30, the goods are not sent, and customers are waiting. And at the same time, they see in the product card and in their personal account how many purchases are left before shipment, for example, 27 out of 30.

Customers are waiting, because the price is very favorable. And the seller until he gets 30 orders does not start production.

Is it very similar to joint purchases or is it?

Have you seen this functionality? What is it called and where to look for solutions?

Answer 1

Collective order.
