Is the sync to QuickBooks Online bi-directional?

Example: All payments must be entered in Ordway. Or if we enter a payment in QBO, is it reflected in Ordway?

As your A/R single source of truth, we recommend routing all payment data through Ordway. We can do this automatically by integrating with your Payment Gateway as well as bulk uploading payment files (or a combination of both). Of course, you can also manually enter one-off payments in Ordway if needed.
