You are able to open, close, and re-open Payment Batches in the Open/Close Payment Batches Express Action. To open or close a payment batch, simply run the Express Action and choose the Payment Batch you want to manage.
Then, simply select the correct action for a specific batch, and you are done. You are always able to re-open and re-close Payment Batches if needed (in cases where a payment was associated with an incorrect Batch Number).
