Parsing Data from Software to My website

There’s many ways to do that. The easiest would be to have the website connect to your software and download the details of the transaction when it’s requested. You could also download entire transaction records to the website and store them locally, but that would create issues if any details changed in the future.

For any of this you will ned to find out what sort of data connections are available from whatever software system that you’re using. Some will have full API’s to connect to, some will allow some form of remote access, and some won’t have anything built in so you’ll have to build yor own connector.
