Tiny ERP is a free enterprise management software package. It covers all domains for small to medium businesses; accounting, stock management, sales, customer relationship, purchases, project management, etcetera. This is the client application. tinyerp-client requires tinyerp-server. Additionally, you will get an error on startup if you do not have matplotlib installed; however, the only functionality lost is presenting graphs. Both tinyerp-server and matplotlib are available from SlackBuilds.org.
