OrderEntry invoicing is not flexible enough for them - and they will need the archiving function. Cost is a big factor here since they are also looking at Quickbooks and I know it would work for them (but I won't tell them that). The workaround using the Cost field is "free" so I'm looking for a similarly cost-free idea.
