Exporting - From my understanding the CSV format matches the QB specification. Are you saying that it matching the filters is an issue or that the format is incorrect.
Treasury for nonprofits - We only just launched Treasury (in December) and nonprofits are a relatively small part of our business so this hadn't come up during our alpha. I am going to investigate why our clearing house does not support nonpfotis, and make sure the restrictions is clearly stated.
Tea Room Deals/Perks - We recently launched this https://mercury.com/perks. Did you see this already and it doesn't match what you want or did you miss it?
Tea - We were revamping the tea packaging so it might be on pause right now. But we do really ship some pretty nice tea normally :).
The other thing that you get with tea room is free domestic + international wires.
Anyway, I can see why your experience was disappointing. I really appreciate the feedback and hopefully we can improve to deliver something better in the future.
