FluentCRM + FluentForms + WP Fusion Lite + ??

I have successfully created and implemented two sites NOT using MemberPress for access privileges to content with the above subject title combination. It works great, thanks to advice from a few people on here.

What I missed about MemberPress was that people can go to their account page and download their PDF paid receipt. I currently do not have a solution for that. It gets emailed to them, but I need a solution that I don't have to get involved with resending receipts.

Does anyone have a working solution that provides people with self-serve access to stuff like this without getting into the range of what MemberPress cost me?

Thanks for sharing your experience with me.
