Most of our clients that use the Quick Expense option instead of raising purchases end up posting the expense incorrectly, either to the wrong account, or the figures/VAT is wrong. Unlike purchases, these can't be amended once posted, only deleted if they haven't been included in a VAT return already. However it seems that duplicate payments can be assigned to these expenses without the ability to see this has happened. I'd like the ability to disable the use of the Quick Expense to prevent clients using them and getting in a state that is difficult to fix without raising tons of credit notes or journals manually.
