Hello Mohamed,

In Odoo online, you can import the custom module with XML and JS files.
You have to create a custom module to extend the POS receipt format and import it into Odoo online.

Thanks,

I tried building a module that works fine in my development enviroment, but just makes the POS hang in odoo online. There is no other way to modify the static files, but with a custom module. Not sure if Iḿ missing something but it's just two files, maybe someone can help us out :P

This is odoo 17:

manifest:

{
    'name': 'POS Custom Receipt',
    'version': 'saas~17.2.0.1',
    "license": "OPL-1",
    'category': 'Sales/Point of Sale',
    'description': "Customized our point of sale receipt.",
    'depends': ['base', 'point_of_sale'],
    'assets': {
        'point_of_sale._assets_pos': [
            'custom_pos_receipt/static/src/**/*',
        ],
    },
    'installable': True,
}

static/src/xml/pos.xml

For some reason xml will get stripped away, nothing fancy, just inherit the point_of_sale.OrderReceipt
