I would recommend VEND as an easy-to-use module particularly for retailers who want to connect their inventory management with their point of sale.
VEND Point of Sale Software operates completely in the cloud. VEND as a Point of Sale module is intuitive and therefore very easy.
Vend also offers an e-commerce solution for your on-line store.
VEND integrates very well with Xero, add recommended hardware packages (PC or Tablet) and you have a complete business solution.
