Hello, we are currently testing out if Odoo fits our needs, and we bumped into this error what we can't find solution to.

Whenever we try to close POS session, we get validation error saying

Missing required account on accountable invoice line.

I have found we need a private address for the employee in the POS, but even with that, it says the same error.

Can anyone help us with solving?

I'd like to add we want to avoid using Accounting package, because we really have no use for that.
