Thanks to those who posted their situation. I'm surprised I have not received PIP yet since I usually have it on the 24th when it's a weekday. My revenue doubled from February to March thanks to additions and improvements, which I was very happy about, but I guess I'm just leery that Google wouldn't pay for whatever reason.
As long as you have not violated the TOS, you have no need to worry. From the payment stats I can see, PIP occured on the 24th for the last 2 months, but January was the 26th and December was the 23rd. As far as I can tell, there's no set day for payment processing, rather just count on it *sometime* in the last week of the month.
You can find the option under your account details. Hint: If your site gets banned, you will loose all the money on hold toooooo Good luck!
I have not recieved my pip either....I also have a balance with adwords, I wonder is one has anything to do with the other...they say the hve the right to hold payment of one til payment of the the other is received but do they enforce this?...its only a couple of hunge on either side...=)
March payment did not show PIP, just went straight to payment on the 27th and that same day the money was in my account. Don't worry, should happen by Friday.
