Dropshipping in easy way

-- HikaShop version -- : 4.6.2
-- Joomla version -- : 3.11
-- PHP version -- : 8

Hi,
What's the easiest way to implement dropshipping in your store? The client provides an xml file with products, we convert this file to csv for hikashop (xml import in hikashop would be very useful) and we update the products every day. The problem is that the client also has other manually entered products that cannot be removed or modified during the update. What's the easiest way to do it?

Thank you.

I have already made a another system that convert XML for CSV that is supported by HikaShop. I have also make a cron job to import products.

But when I’am importing products from file, product that was created by client by him self, manually is disappearing. If I turn off function “Delete variants not in the CSV”, product that was deleted in supported XML file still is in shop, so I can’t do that.
It could be perfect to have a function in HikaShop that will prevent deleting product that was manually insert by user on import CSV file. Maybe some checkbox in every product – don’t delete this product during importing CSV file.

It would be also grate to import XML files. With CSV files there is a lot of problems. I spend on this many hours and many errors occurs.

Maybe now is some solution to my problem and I don’t know about it?
Than you for help and I hope so, that my opinion will be helpful for you.
