What is the best way to customize the ERPNext POS interface without modifying the core code?

How can we change or add features to the ERPNext POS screen without editing ERPNext’s original/core code?

Hi @Suheb and welcome to the community

Normally Hooks are how you could customize the Framework itself.

For ERPNext you have options Custom Field and Customize Form are some of the options you have

Hope it helps

it depends with the needs , but if its just small small changes , you can do webhooks and custom fields but if you need major changes you can do a custom app and you can also use VUE
