ERP vendors that have good high-end packages are increasingly moving into the Tier 1 space, at least into the divisions and department of companies that use an enterprise-level application to run their financial operations.  The signs are abundant. NetSuite this month signed an agreement with Informatica which will integrate NetSuite and Tier 1 products. Also this month, Epicor CEO George Klaus stated, “We are going upmarket” and noted that Epicor 9, which is making the effort possible, can handle about 3,000 concurrent users.
