How to implement the functionality of an online storefront?

Question

1C-Bitrix

Hello! There is an online storefront without a basket, which is filled by sellers by filling out applications. I want to ask with the help of what tools is the easiest way to implement such functionality? what can be bundles of plugins, templates, etc.
maybe there are templates, scripts ready. as far as I understand, this site is implemented on cms bixrix on a self-written template?

Answer 1

For example, marketplace.1c-bitrix.ru/solutions/capital.magazinlite

Answer 2

The easiest marketplaces like Carro.by or the same online storefront that you provided are self-written modules on frameworks like yii2 or lareval

Answer 3

If there are up to 5000 products and a couple of filters (and why more?) - write yourself
