The other thing you need is a transaction I'd. Transaction amounts can change over time. I got caught by this when I tried to build my own tracking tools. Credit card transactions in foreign currencies commonly change over time. My balances never added up and I couldn't figure out why. Turns out most banks support ofx. That has IDs so you can track the changes.
