Start converting currency at better value — right inside QuickBooks.
Castle Currency works with your QuickBooks workflow and adds the missing piece: a better approach to global transactions — so you keep more of what you earn.
If your team converts currency when it's convenient (accounting says so, invoice day, month-end), your results are largely at the mercy of whatever the market is doing that day. Saving a few points on spreads is fine - we can do that. But if you want a meaningful difference in your bottom line, we help you improve how conversion decisions are made.
