Hello,
does someone have any directions which way we should work in Odoo8 and the POS.
Situation: User registered payment by Cash, but the customer paid with Visa. During closing control of this POS session, he noticed his mistake. How can he change the payment method from Cash to Visa in a proper way. Or how does the financial manager can do this? It has to be done before the POS session is closed, because the end balances are not correct.
