I am just starting with ERPNext and I am very happy with it so far. I am a developer, so naturally I want to know how I can start tweaking things. I have been able to add a custom button to the Sales Invoice form by following the samples on the custom script page. However, I would really like to customize the POS form (which I think is also a Sales Invoice?). I can’t figure out what I need to do to customize that page.
I have found this file in the Git Hub repo which seems to control most of the page: erpnext/pos.js at 2b9c95a9404bf4b59235700c874aa7674638a196 · frappe/erpnext · GitHub
However, I am not sure how to write a custom script to interact with this page. I could just add my code to the bottom of the file, but customizing a file that will be replaced by an update doesn’t seem like the best way to apply my customizations. Is there a better way?
Thank you for the help!
