Hi primordialsoup ,
Thank you very much for your reply.
I am incredibly sorry if stuff is taking too long. ATUM has a very limited budget and small, but a good team. We spend 50%-60% of the time helping users for free. I do not want to let my users down by reducing the hours of support so stuff will take time.
For any POS you may need to build an API that ATUM does not have yet. API will be developed this year before Summer we hope.
Once again, I apologise for any inconvenience caused.
PS: if you are not happy and want to consider a different 3rd party solution instead of MI, please, do let me know.
