Hi, this is quite a small task but let me know if you are interested and we can work out a budget and time frame.
At the moment when a customer uploads a file with an order we have to login to the backend, go to sales > orders and download the attachment.
What we want is for a link to the file to be included in the sales email that gets sent out.
I have attached 2 screenshots, 1 of the current sales email and 1 of the backend.
Let me know if you need any more details.
