@ParasY1724 That's amazing, but can you please tell me where exactly you plan to place this feature on the website and when users can download the invoice? I think users can download the invoice after the payment, right? If that's correct, we're currently working on the payment integration. After it's completed, I'll let you know to work on it. Otherwise, please describe when users can download the invoice and other details.

@mdazfar2 I was referring to Myorders page

But , I think it would be better to work on it after payment gateway is merged

Alright! @ParasY1724

Right now, I'll keep this issue open, and after the payment integration is done, I'll mention you here to work on that.
