Is it possible transform Hikashop into prices engine comparison?

Hi,

HikaShop hasn't really been made to do that. First, there is no system to have different prices for the same product for different "vendors". You could potentially get by with variants, HikaMarket vendors and listing the variants as a list on the product page. But then the import from the 3 rd party sources would have to be completely cusotm made to be able to support that way of handling things.
So It might not be impossible but it would require development work at least for that.
And then, you'll probably need more customization on the views of the frontend to better catter to the needs of a price engine comparision website.

Hi,

Removing the add to cart button is no problem.
You can set the stock to 0 for example and then change the text "no stock" with a translation override.
Then, you can create a custom field of the table "product" so that you can store the external URL.
And to display a button with that URL, it's quite easy too.
The exact code will depend on how you configure the shop, and which view file is used but it will be something like that to add:

<a href="<?php echo $this->row->XXX; ?>" class="btn">Go to the page</a>

Hi,

If you use the Products>Import screen, you can import your CSV there. In it, if you have a column with the name corresponding to the column name of your custom product field for the external link, the import system will import the link in the custom field. So it sure is possible to automate that.
Regarding the plugins for HikaShop, there are many. You can find some in our marketplace:
