Ask HN: What ERP system do tech startups use?

The 'E' in ERP is for 'Enterprise' (http://en.wikipedia.org/wiki/Enterprise_resource_planning), which in my mind is another stage of development beyond startups.

As pbreit says, use QuickBooks.

So far my investigations have led me to a few interesting companies using Netsuite, specifically Groupon, Sixapart, Gawker and Atlassian. Still investigating :-)

Along with this, does anyone use OpenBravoERP? Intriguingly, it has always been one of the top SourceForge projects.

Tech startups don't use ERP systems. Pretty much everyone starts with QuickOoks.

Quickbooks cloud or excel.
