I was wondering if anyone has any experience with remote pings to a invoice generating 3rd party? (Using the Membership Pro Plugin)
I've been looking all over, but I can't find any websites or programs that can generate invoices with a remote ping.
So if anyone knows any service that supports this, tested or untested, please let me know.
The laws in Europe are very strict, so it's pretty important that I find something that is able to do this.
