A product for a specific user

Hello Hika forum, this is a pre-sales question:

I would like to know if it is possible in any way to create products that only would see by a specific user (or visible by everyone but only can buy it a specific user). Options:

1. Creating a group for each user, and control it with access level. But as this option is "Business" I can´t know how it works and if it is possible.
(Although to create a group for each user is not the best)

2. Adding the product to the user´s cart with 1 maximum amount, so like this other users could not buy it (although I don´t know if it is possible to book the product while it is in any cart). But there is a problem if the user remove the product from his cart...
(too complicated)

3. Being the product unpayable, untill a specific coupon is added.

4. Being the product hidden, only accessible with an specific url.

5. Any other "easy" way?

6. Hikashop could offer paying small extensions like this?

Thank you!!
So 1 and 4 there are the best possibilities.

4. That's potentially possible yes.

4. How can I hide products? Or easier, how can I hide a category and get into this category all products I want to hide?
As I see, users can go always to "Categories listing" to see all the categories/products.

5. You mean the same option as 1, don´t you? It is almost perfect, but the access level is only with groups, not with users.
It could be a very hard work to create a group to each user, but it is possible

The issue with small extensions here and there is that you would spend a lot of time searching, installing and configuring each small extension while it wouldn't mean that it would end as cheaper for you in the long run. With the Business edition, you install it and you have access to everything for a fixed price.

6. You are right, probably I will buy Business edition due to it is very complete. But I mean if I buy it, is Hikashop open to create
a specific extension like an access level but also with user (not only groups)? (maybe it isn´t possible to create something like this, or is too difficult)
