Developing ERPNext as a Community offers the greatest positive contributions. One of the best ways to support open-source software is by leaving the footer credits. It will allow more and more people to get to know about the software and support the software which will benefit you as a software user.
However, the freedom of GPL license allows you to edit or remove the copyrights of ERPNext software.
How to remove the ERPNext footer?
Step 1: Go to Website > Website Script
Then add the following script:
frappe.ready(() => {
$('.footer-powered').addClass("hide");
});
