I like that they provide support in many languages around Europe (I'm from Germany).
They also have good documentation available online if you need it! You can definitely learn how things work with them but at first there's always something missing or confusing so be patient when asking about stuff - maybe someone else will spot what your question is before trying everything yourself :) If not working out perfectly smoothly then just try again later because this usually happens only once after some time being used together ;) Good solution choice regarding integration into SAP ERP system which was needed for my job.
