This request sounds a lot like something I've been trying to get, and no I don't think the export of all payments and invoices does it.
We evaluate the profitability of each of our events -- the export from Finances does not carry the specific event name. I would want to sort by event name.
We reconcile the financials for each event separately so that the Treasurer knows how much revenue is in checks and Paypal for that event, and to be sure member accounts are correct. WA Registration by Type gives us total Revenue for that event, but that doesn't tell us all we need to know.
Currently I export attendee data for each event separately, delete all but relevant financial info, sort it so the event manager can verify the correct amount they have in paper checks so I can be sure our member account balances are correct. Our event managers often settle a member credit for payment incorrectly, but actually record a new payment (using a tender type for member credits thinking that does it). There is no easy way to find these errors (which must be corrected since members get credits they are not supposed to have).
For event reconciliations, I then add back in any cancelation charges for late cancel fees for that event. Finally I add in Paypal fees for all the Online transactions for the event (something I would not expect WA reports to do), but need to sort the transactions/event by payment type to allocate the PP fees to that specific event. Without this information, we don't have complete data for pricing our events for next season.
It is very cumbersome and I spend a lot of time trying to verify member credits are correct, (and helping event managers over the phone settle credits to try to prevent these errors) since the audit trail is not clear for this, especially when a trip leader makes errors on settling credits which is a common occurrence.
We are probably going to dedicate a board member to act as "assistant treasurer" to focus specifically on the new WA billing issues next year to help with all this additional work.
