Creation of a small online store based on a ready-made template

As in the title. Currently, for budgetary reasons, the store is hung on the wix platform. Despite the ease of use of adding products, the store is not integrated with Polish payment plugins.

What do I care about? (If I use unprofessional vocabulary, please forgive me) - CMS - I can add products myself at any time, make updates to the site

- 5-7 sub-pages, with the possibility to duplicate them

- newsletter signup

-platform for customers after scanning QR code

- automation -sending an e-mail after placing/sending an order

-plug-in payment plus shipping

- accurate tracking of visits to the site (plus possibly other statistics after detailed discussion)

-English version of the website

- contact form

-discount codes (personalization and their visibility in the shopping cart, including a free product)

-the site should be visible to all browsers and be responsive (comp. tablet, mobile).

-products from the store visible in the google store

-others that may be worth introducing that I don't know about
