If you would like to export a Filtered List of Bill Batches, make sure to apply the filter first. Otherwise, you will export the entire list. However, keep in mind that the amount of entries you will see will be based on the Settings Performance tabs configuration. Administrators who wish to speed up performance may elect to limit the number of historical items that show up by default. Once you have obtained the desired list of bill batches, click 
in the accounting center toolbar.
