That should be no problem and something you can do with Microsoft Dynamics RMS (POS). The great thing is that RMS is able to be easily integrated with your Magento store so you can have one integrated system. We actually provide cost effective “connectors” to help you integrate your Magento store and POS system like Dynamics RMS.
By connecting Magento to the POS system, you can easily syndicate items to nChannel, and merchandise them for Magento and all your other channels, eliminating redundant data entry procedures. nChannel can also push sales orders from Magento to your POS and help you keep inventory synchronized between the two.
