Hello @Mona,
The file location I have provided is not to change the view of the PDF invoices, it was for the inside WPERP. However, WPERP doesn’t manage the PDF invoices itself, another plugin called ‘WPERP PDF Invoice’ handles it. You’ll need to customize this plugin.
The mentioned plugin has just two files, so, I hope you’ll get which file you’ll require to work 🙂
Thanks
