bank-payment/account_voucher_killer

Prevent the usage of voucher from invoices

This add-on disables the "Register Payment" button on customer invoices and the "Pay" button on supplier invoices.

It also disables the voucher-related menus entries such as "Sales Receipts", "Customer Payments", "Purchase Receipts", "Supplier Payments" and "Journal Vouchers", "Sales Receipts Analysis".

More precisely, this module adds a group "Use voucher in Invoices" and only users in that group see these buttons and menus.
