Hi Igor and thank you for your reply!
I have two different scenarios that I am concidering:
1: To build one main site which is for international customers (outside the EU), one subsite that is for my own country (Sweden), and a second subsite that is for the remaining EU-countries.
or:
2: To build one main site for international customers, one subsite for Sweden, and one subsite per remaining EU-country (this should be 26 subsites).
In either scenario, my plan is to use the Subdirectory installation method, so my main site would be named:
https://sitename.com
And the subsites would be named:
https://sitename.com/se
https://sitename.com/dk
etc…
The reason for creating a multisite network is to be able to provide customers from different countries with different languages, currencies and tax-options.
After posting my question yesterday, I also found this article: https://www.ads-software.com/support/topic/wordpress-multisite-111/
Is the meaning of this article that I can use the WooCommerce Stripe Payment Gateway on my main site and also on all subsites with only one Stripe account, Stripe keys and Stripe configuration?
Thank you!
