When syncing transactions on Ramp, you may run into an error message telling you that your accounting period is closed. This occurs when a transaction you are trying to sync belongs in an accounting period that has already been closed in your software.
You can always re-open your books for that month and sync that transaction into your software. Alternatively, you can edit an accounting date on Ramp directly.
Click on the transaction you need to edit on your accounting tab and scroll to "Advanced"
From there, edit the accounting date to a period that is currently open in your accounting software.
Afterwards, you'll be ready to sync!
