I've used Acdev POS with serialized inventory, it works.

Why not contact Acdev and have them show you? www.acdevware.com/ContactUs.php

Dear Ettienne,

I do some transaction on Acdev POS for this serialized item, but most of the document that has serialized item is unable to be process. While checking on the POS Server, the error is unclear just mention unable to process , please retry. This got me quite confused. Any Error you encounter on running the serialized at the time of implementation?

Hi there,

InfoPOS has a very powerful integration with IC Serialized Inventory for Sage 300.

We would be happy to take you through this integration in detail. Please visit https://www.infopos.com to find out more or to request a demonstration.

Hope this helps.
