Hi, looking at websites there doesn't appear to be a specific term for "low cost" in this context. Some who advertise standard components often use the term "kostnadseffektiv". This is of cause broader than "lavkostnad", but "lavkostnadsautomatisering" is rather clunky. "Kostnadseffektiv automatisering" flows much better, but there are several sites that insist that their taylored solutions are "kostnadseffektivte". You could maybe contact someone in either of the following branch org's:
