This project is on a bit of a hiatus as the client I was building it for decided to use another finance provider hence the 70% completedness of this!

You can install to your own project with composer require billythekid/v12finance

Feel free to PR the few missing classes or I'll get to it as a side-project eventually, hopefully.

Here are the API docs

Here's some example code for how to use this
