Does anybody knows good solution for products sync across multiple independent Magento 1.7 installations ?
I made an extension to do this exactly. It lets you sync orders, products, prices and stock from a base site to another site on a different magento installation. Great for people looking to manage private label websites.
Automatically download new products from base site to private label site
Automatically update private label site stock quantities based on base site
Automatically update base site stock quantities based on private label site orders (auto subtracts)
Automatically push orders from private label site to base site (under customer name or private label name)
Customize price mark-up per attribute set per private label site
Cancelling order on private label site cancels on base site
You can get the extension here:
Private Label Site Sync Premium Magento Extension
Disclaimer: This is my extension, so technically this is self promotion. None the less its still a valid solution to your problem. I can give a discount for new customers and we can setup on dev server. Free installation, free lifetime updates, free lifetime support.
Hope it helps!
