As a treasurer I generally ask for a copy of the accounts a few days before an EC meeting. The usual result is that I can say to the meeting that things look to be generally on track with the budget, perhaps that we are a little over spent on one item but a bit under on something else. Perhaps that I have sent a polite reminder to the few units that are shown as behind on levies. Our manager usually produces a comprehensive set of accounts within 24 hours. I think it is simply a matter of calling up the right OC in their software, hitting print and sending me a PDF version. It is then easy for me to see that we have paid (say) 6 of the 12 usual monthly accounts from our gardener and consequently have spent almost half of what we have budgeted for gardening and so appear to be on track for that item, and so on.
It does not seem to be beyond what the managing agent expects and not hard for me to interpret in spite of little relevant background expertise (biochemist, not accountant!).
