Answer 3

Take 1C Trade Management, it is the most popular. You can buy, for example, from the first bit. Well, or look for it yourself, I know that there are people who are ready to share the platform and configuration for free, but it’s not customary to talk about such things in decent places like Habr)
When installing the configuration, you can install a version of the database with demo data, so almost everything you need will be there.
If there are not enough goods, it is easy to write some kind of processing that generates the required number of goods.
