It was easy for us because we were already using comtrx point of sale system which is integrated with many other software applications such as Sage 50 accounting package. The support staff from ComTREX are very knowledgeable about this product line so they could easily guide me through any problems I might be having at anytime during my integration process. No dislikes here; everything that it does has been beneficial when integrating to their POS System! We've used several different vendors over time but nothing compares to how well these guys do what there doing i.e., Integrating an ERP environment into one application instead of multiple separate ones.
