Has anyone ever sent a slow paying agency's client the bill. Especially if it is more than 90 days old?
I may have done worse than that. I had one client who was 6 months late. I was about to call in the collection folks. Before I did that, I spoke (confidentially) with some other business associates of the client to get some inside scoop on what was going on internally. Glad I did, because they ultimately paid me once they knew their reputation was at stake.
