Blue Link ERP is available as a cloud or on-premises solution with the ability to switch at any time. It's functionality is comparable with NetSuite.
If you're speaking strictly in terms of ERP programs then most of the major players in the market offer some kind of cloud-delivery version of their core offering. Just about every variant of Microsoft Dynamics has a cloud version. The same goes for SAP Business One and JD Edwards EnterpriseOne (Oracle).
SAP Business ByDesign for manufacturing, supply chain and professional services. Plex for manufacturing. These two plus Netsuite are the true multi-tenant cloud ERP packages. There may be more but taking an on premises ERP package and hosting it and pricing it as a SaaS offering doesn't make it equivalent to Netsuite which is a true multi-tenant architecture. Although from the customer perspective that hosting and SaaS may be sufficient if they can deliver similar functionality for prices comparable to multi-tenant offerings.
