What is the name of this type of software?

Question

Online shopping

Hello.

I can NOT formulate and find the name of software like an online store, but not goods, but rather services. In this case, the construction theme.
Minimum functionality - the main thing is that the client, having typed a certain number of services on the site, has some analogue of the estimate or something ..
Is there such software in nature?

Answer 1

It's like Ikea had a planner. Type you draw a room, choose furniture from the catalog, arrange it. Do you get an estimate at the end?

Answer 2

This is commonly referred to as a service calculator. There are several constructors, you can write it yourself, you can ask the developer.
