They have their own lame, internal excuses. Often you're dealing with payment from a completely different procurement dept than the group you're delivering services to. So you often have to work your relationships in the project team to nag a completely different part of a company to get you paid. It's a nightmare at large companies. I had one large client that decided "we aren't going to pay bills in Dec". I'm pretty sure it had to do with the CFO playing cashflow games at the end of the year so their numbers looked good. So all vendors got dicked over... Of course if you're a giant firm, you can ride the cashflow waves. Or if you play golf with the CEO, you can put pressure to get payment. But if you're a small firm or a freelancer, the project team you work with can't really change much about what's happening. Also, net-60+ clients have a pretty "bad smell" because you know they set that up so they can play cashflow games to make their books look good.
