This is exactly the problem my startup is trying to solve. We'll have the materials management portion (purchasing, inventory, warehousing) soon- June is the tentative target. There seems to be a pretty big gap between excel spreadsheets and huge business ERP/MRP/SCM/CRM software. Unfortunately, I think what you describe is right in the center of it. My first client is transferring off an amalgamation of Intacct Small Business and Salesforce.com. I wouldn't recommend it based on my experience, but it has worked out OK for them for about two years. They're at about 8M/yr in sales right now, and if you're under that, that pair might work OK for you.
