You can individual invoice texts add for each individual contact. These appear on every invoice or order that you create for this contact.
To make the settings for the payment text for a contact, you must first install the module “invoice text” to your contact. If you only want to create an invoice text for the selected contact, add a separate tab to their contact view (how – read here). But you can also add the module for all contacts.
Invoice texts contact
As soon as you have added the module/widget to your contact, it will appear under the corresponding tab. Here you can first find the respective accounting area, as well as payment type Select. Then select a payment text by typing its checkbox activate. You can find out how to define a payment text here.
