Why Reserve Checks for Manual Payments?

Prior to creating a manual payment, you must reserve payment numbers for each bank account you plan to use with manual payments. You will also reserve payment numbers for payment replacement. Creating a replacement payment

The process of reserving checks has three functions:

Reserved - Once reserved, payment numbers are not available for normal system payment use. Reserved payments are used for manual payments or payment replacements.

Unreserve - The unreserve function makes previously reserved payment numbers available again for system use.

Void - The void function is used to void payment numbers that were accidentally destroyed but not used. After you void a payment number, the payment number is taken out of circulation and is not available for use with manual or system payments.
