Understood. As we are targeting small local vendors, we do offer
standardized and preconfigured verticals. We do not offer individual
customer-specific modules for the same functionality.

At the moment I run different virtual servers for production, testing
and training, but each of them multi-tenant (in my sense), means one
Odoo instance, one Postgres instance, separate databases for each customer.

In my deployment the customer has no SSH access, (of course) no Odoo
Superuser access (database manager) and not even admin access on his own
database. The customer is not allowed to install modules and has only
"editor", but no "design" access to his own website.
The reason for these restrictions is mainly to protect the customer from
harming himself.

Thank you for your information and the test access. I will try it as
soon as possible.
