This is an OPTIONAL feature of fixed fee billing.
You may enter an integer value that will control how many times the fixed fee amount specified for this project will be billed.
For example, if you put 1 in this field the amount will only be billed on one invoice. The fixed fee project can still appear on subsequent invoices but the billed amount for it will be zero.
If you leave this field blank there will be no limit on the number of times the fixed fee amount of this project will be billed on recurring invoices.
