I feel like I need to chime in, here.

A,  I am NOT a bank.......................I am finding very difficult to pay my copy costs at my ROD's.  Several of my clients are approaching 90 days on payment.  The ROD's that I deal with expect payment within 30 days, I expect the same. 

B.  The clients that I do have that pay me in a timely manner are bearing the brunt of those that don't.

C. To my clients that are WAY behind in payment:  Not my problem that you took on work for a company that is WAY behind on paying you (and you forwarded that work to me, and I performed that work, including copies).  

D.  I have not previously charged for plat maps and tax reports that I  can get online, but I am going to start doing that,  I'm using my ink and paper and time to do this.  Additionally, I think I will start charging an additional fee to the actual cost of copies.

 I simply cannot finance all of these copies.  I need to stay in the good graces of my ROD's. 

An additional note:   

I am letting any new client know that I bill at a minimum once a month - most new clients are billed at the time of service.  If my invoices are not paid in a timely manner, they are shut off.

Just my two cents.
