I have been doing ERP consulting for about a decade now and I tend to disagree. I think we have a lot ph ERP options now in the paid space apart from just Quickbooks and SAP. You need to pick and choose based upon what is the most complex operation for a company- be it multi currency financials, complex supply chain or some other parameter. Then you can pick from lowest complexity to highest in the following manner

* Quick books

* Sage

* Dynamics / NetSuite

* JD Edwards / Infor / Manhattan

* Workday

* Oracle EBS / SAP

Each of those on the same line are similar in features and complexity.

This is obviously not a complete list - just the ones I have dealt with.
