Ok, after some searching I have managed to find something that should automate the importing of CSV/XML files http://www.orbis-software.com/integrations/parse-a-csv-file.php. I had a demo from the guys at Orbis (Sven) and they can also provide PrestaShop integration with my ERP system so it will do more than syncing orders, stock levels etc. Has anyone any experience of using them? P.S: Hope this info helps.
