We built our own order management system but Stone Edge has one that looks pretty good. It's built on Access but as you grow has the ability to go up to a SQL Server database. Netsuite is also available as a SAAS not sure of pricing but we have a small competitor in the 2-3 mil / year range that uses it. You can still use Quickbooks as your accounting package. Just don't keep the orders in it as someone has already mentioned.
