Can I specify to defer line items in a batch input file?

Answer:

Yes, as with the graphical user interface, individual line items below $20 can be deferred. Amounts should only be deferred if they are below the bank minimum. For example, if the bank minimum is $10, then all payments above $10 are expected to be made. Furthermore, payers who choose this option should be prepared to present documentation of this limitation, if requested.
