Syn user data for multisite (need help)

Hi guys I am looking a serious piece of advice from you.
Is it possible to syn ultimate members data and woocommerce orders data from child site to parents?

I am thinking to go with multisite where A us my parents site and B will be a child site.
Both sites will share same plugins. The only difference will be the language and currency.

I know I can achieve this by wpml plugin but my problem is different (second currency is not supporting that’s why I am going to multisite structure).

So customers who signup and orders from Site B (child ) should be able to login into site A (parents).

I am not code expert but I can do copy paste or setup any plugin.
