Before we upgraded to MultiFlex RMS, we used QB multi-store, function was terrible, I think we just grew out of it, we needed real time data-sync or at least close to it and something more tailored for retail business.
I looked at Revel, Light Speed, Vend, etc. many more that I do not remember the names, even some that interface looked nice, but back-end was not even close to what RMS can do.
Customer service is much more dedicated since it is in-house, amazing people, hard working and "can-do" people, same people every time you talk so awesome relationship, real time update and exchange (15 minutes) really helps, we also launched E-commerce and loyalty points program.
Much smoother than I thought, since techs are with you day and night, they will stand by for any issues when we need. I want to say special thanks to men behind the show Allen, Graham the Brit amazing key adviser, superman Parry and Moe and Anita for their HARD WORK and great assistance for our success.
