>push clients to accept monthly net 15 or net 30 invoices. Doing any more frequently is too much overhead and cashflow isn't a huge concern for me.

Just a thought... after I had a client try to not pay me / slow pay me, I moved future contracts to a more aggressive invoicing / payment schedule, plus I added a harsher late payment penalty. Especially if you have payroll to make, it becomes very important to never let a customer get too far into you.
