For cost effective and easy to use inventory system I would suggest our BCI Basic Inventory Control kit. This bundles includes the Honeywell Dolphin 6100 portable data collector and the Wasp Inventory Control software to manage your stock. The 6100 will allow you to collect batch inventory changes and then batch load the data back to a PC running the Wasp software. It is a very intuitive system and is expandable to add additional portable readers if needed.
