How does Split - Partial Payments affect standard templates created in the store?

Our Split - Partial Payments app does not create any additional email templates and does not change any of the old ones.

Instead, it uses a custom_message variable that is used for showing messages here. If your Draft Order Invoice template has been changed, please be sure that it contains the custom_message variable. If you want to inform your customers, it is necessary to add this variable, as shown in the following example:

{% if custom_message != blank %}
<p>{{ custom_message }}</p>
{% else %}
{% endif %}


This code can be placed into a template, and the defined default message will be used.
