Do you know a modular product catalog + shopping cart solution to integrate with an existing website?

Question

CMS

Good day to all!
Given:
- A working landing page on Tilda that converts sales (accepted by phone): ji-fruits.ru
- Almost complete lack of programming knowledge
What you want:
1. Implement a simple product catalog with a basket to reduce the load from the phone
How to:
1. It would be nice to find some cloud-based solution like this: https://www.shoprocket.co/demo.html  - a simple widget that has a catalog control panel under it with a nice and most importantly manageable design (this one is unusable due to the lack of the necessary currencies in settings)
I know about Ecwid, but it does not fit due to the lack of the necessary settings in the control panel. Flexible enough if you know how to code, but this is not about me now :)
Anticipating possible questions, I’ll say that for me now moving to a new platform that is specifically tailored for creating an IM (unlike Tilda) is not the best solution, as it will require in fact, redesigning the site from scratch, and this is completely unreasonable at the current level of business.
I would be glad if someone can recommend some solutions - perhaps you have heard of some CMS that allow you to create a storefront, generate code and embed it on an existing site (in this case, on Tilda).
Thanks in advance!

Answer 1

smartlanding.biz/wp-content/themes/simply-vision/d...
may suit you, there is an archive with a basket script.

Answer 2

Almost complete lack of programming knowledge

will not work in any way.
With such manipulations, it immediately becomes necessary to be able to administer, write / understand what is happening in the code on the front and on the back . It is
better to turn to specialists to add functionality and place it on hosting / vps
