We use RF Pathways for the last 6 years, they are great to work with good system priced right but we may be outgrowing them we started out around 225,000 sq ft and are now up to 500K and our business is getting very complicated. It still works very good but I think like most software unless you spend the big bucks right from the start and go top of the line chances are you will outgrow it, we are on our 3rd TMS system and it will be our final as it will handle anything we throw at it. I always remember talking to a top systems guy who said that no matter what system you choose they all have good and bad sides you just need to know what you can live with and how much you are willing to spend.
