Matt,
How did you integrate the other pos systems such as Micros into NAV? I have never used NAV before and so I am not very well versed on the product at all. Was there a special connector that your company made to establish the integration or was it done natively through the software? Can you point me to an area in the software to look at this? I've got 2013 NAV downloaded and have been looking at it but again I can not find anything in the help files that talk about this.
