If your are serious buyer EasySale POS is here to stay and conquer.
You would do much help if you can define your needs(important features) than stating a size of your store.Your store can grow overnight ,I wonder if you would replace the inflexible software already in operation.
Easy Sale POs is seriously very scalable and flexible right away. With multi stores, locations,multi currency,payment types that you accept(cash,deposit,gift cards, cheque,M-Pesa you define them),each store with multiple Sales Points,..set up can be
1. Localized servers(Branch-HQ) with synch, import/export
2. Centralized server with nods span into LAN/WAN.
