Hi,

I need to generate an email or SMS to my customer after invoicing which is manageable

But in the message there should be a link where the customer can access a page to see the details of their purchase. There will be also a download button to download their invoice.

I have seen this feature on Odoo.
Please guide how to achieve this.

That for, customization required.

Otherwise please make and take a web form right to customer user.
Customer can check the details or also print the document.

Thank You!
