Construction purchase order software

All,

My cousin owns/runs a small construction company. It started out as an excavating business and expanded from there. He installs septic and drainage systems, does a lot of hauling, recycles concrete, various other things. His wife does the books via Quickbooks.

He called and asked me about "purchase order" software. That's what he says he's looking for. I think he knows what he wants and at the same time _doesn't_ know exactly what he wants. The best he was able to articulate was he wants to make sure what his employees purchase for the company gets charged to the correct job. He says what's in Quickbooks in this regard isn't what he wants. There may be some employee pilfering going on. I don't _know_ that, I'm just inferring that from his voice mail.

Anyone have some suggestions where to look? I don't think he can explain it any better, I think he'll know it when he sees it.

Of course, no software is a panacea. If he doesn't have the proper controls on his employees, well, you know the rest.

Thanks.
