As it is asked in the title, we are a winery in France and would like to create custom alerts for several customers, that would appear when creating a new order.
This popup would show several important information to remember.
For example we have a customer that pays 2/3 of all its invoices in one time for the whole next year but sadly the Deposit function doesn't work for us so sometimes we forget that 2/3 has already been paid and send a false invoice.
Thank you for your help, wishing everyone a nice day !
You will have to use a page extension to add the code to allow this to happen, possibly also adding a "flag" field to the customers you want the message to appear on.
