HikaShop store shared on exclave sites

[sarki]

Hello,
I have a client who currently has a website with a Hikashop and Hikamarket online shop, offering products to retailers who, through the same website, resell them to their customers.
He wants to grow his business by offering these retailers their own customer interface.
I have looked at several solutions, from the simplest to the most complicated, and what you can do with your extension seems to me to be the best option. The ability to choose which tables to synchronise is a plus.
The idea is to have the slave sites as subdomains on the same server, with separate databases.
I saw that Hikashop and Hikamarket were properly supported.
I understand the principle of synchronising databases and slave sites within the same hosting space. I imagine there is an FTP file transfer system for performing the necessary updates/file transfers on the slave sites.
I read in one of your case studies that profile avatars were not transferred to the different sites. Can you confirm that images of a new product added to the master site's shop are visible on the slave sites? The images are called up by relative URLs...
Please confirm that your extension allows me to carry out this project. If you require further information, please let me know.
Yours sincerely,
Sarki
