I've previously had one big frustration with them in that their reporting sucks. I have several product lines being sold (I'm in the hundreds of thousands of dollars of revenues in a year with the average payment way under $100) and Paypal isn't really able to help us track by product line. Even when we have the payments come in under different emails, they can't sort them out. It turns out the solution is to open a child account. The process was cumbersome, basically, open a new account, get it approved, get it linked to the old one, drop out all the fees, and the child account can ONLY withdraw money up to the parent account. And it's an automatic process which happens nightly. Which would be fine except we have some refunds (we do a money-back offer) and about 4% of our customers take the refund. Paypal does an automatic withdrawal every night but on the days that there are refunds, they try to withdraw too much and it produces all sorts of emergency warnings and failure notes.
Second big problem I just realized. My account has reserves. In fact, they hold onto 20% of my funds for 90 days on a rolling basis. It's really not something that I can work with. Have any of you any experience with this? I spoke to Paypal at some length last night and the agent said: "There's no way you can ever do anything about it. Ever! This is just the way it is. I've spoken to my supervisor dude and you've got the 20% withholding on you forever. You've been approved this way and there's no way ever that you will ever get reviewed again or get it removed. You might try setting up a new account and see if you get stuck with the same thing." Heh thanks!
I read the Paypal rules and found this:
