I have been using this software for almost 3 year now with no major problems or issues that would make me change my mind about working here so far! The interface is easy enough but there are some minor things which can be improved (and maybe they already were). Some features like adding new users from CSV files could use an improvement too though nothing much serious at least not something you cannot live without if we talk seriously :P Highly recommended!! If your looking into buying softwares then do consider having them tested by experts who know what's good/bad etc first before making any decision because sometimes people get fooled easily when seeing just screenshots only :) We used tectrades products since couple months ago till date - mainly ERPs such Salesforce CRM integration & MS Dynamics GP Integration.
