I installed Odoo13 on localhost, there are several apps that are free that we can use. But there are also several apps that we must upgrade to use it.
Now, I want to use the Odoo Accountant app in my local, but it seems we must upgrade it before.
So, my question is: if I upgrade to use the Accountant feature, can I use it on localhost after it..?, and should I also do the payment bill every month..?
